Access to this vpn is provided through a public port on the network host for the project. This allows users to have free access to the virtual machines in their project without exposing those machines to the public internet. + +Cloudpipe Image +--------------- + +The cloudpipe image is basically just a linux instance with openvpn installed. It needs a simple script to grab user data from the metadata server, b64 decode it into a zip file, and run the autorun.sh script from inside the zip. The autorun script will configure and run openvpn to run using the data from nova. + +It is also useful to have a cron script that will periodically redownload the metadata and copy the new crl. This will keep revoked users from connecting and will disconnect any users that are connected with revoked certificates when their connection is renegotiated (every hour). + +Cloudpipe Launch +---------------- + +When you use nova-manage to launch a cloudpipe for a user, it goes through the following process: + +#. creates a keypair called -vpn and saves it in the keys directory +#. creates a security group -vpn and opens up 1194 and icmp +#. creates a cert and private key for the vpn instance and saves it in the CA/projects// directory +#. zips up the info and puts it b64 encoded as user data +#. launches an m1.tiny instance with the above settings using the flag-specified vpn image + +Vpn Access +---------- + +In vlan networking mode, the second ip in each private network is reserved for the cloudpipe instance. This gives a consistent ip to the instance so that nova-network can create forwarding rules for access from the outside world. The network for each project is given a specific high-numbered port on the public ip of the network host. This port is automatically forwarded to 1194 on the vpn instance. + +If specific high numbered ports do not work for your users, you can always allocate and associate a public ip to the instance, and then change the vpn_public_ip and vpn_public_port in the database. This will be turned into a nova-manage command or a flag soon. + + +Certificates and Revocation +--------------------------- + +If the use_project_ca flag is set (required to for cloudpipes to work securely), then each project has its own ca. This ca is used to sign the certificate for the vpn, and is also passed to the user for bundling images. When a certificate is revoked using nova-manage, a new Certificate Revocation List (crl) is generated. As long as cloudpipe has an updated crl, it will block revoked users from connecting to the vpn. + +The :mod:`cloudpipe` Module +~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +.. automodule:: nova.cloudpipe.pipelib + :members: + :undoc-members: + :show-inheritance: + +The :mod:`crypto` Module +~~~~~~~~~~~~~~~~~~~~~~~~ + +.. automodule:: nova.crypto + :members: + :undoc-members: + :show-inheritance: + diff --git a/doc/source/concepts.and.introduction.rst b/doc/source/concepts.and.introduction.rst index 29b8f064a..d2ab6f14b 100644 --- a/doc/source/concepts.and.introduction.rst +++ b/doc/source/concepts.and.introduction.rst @@ -129,7 +129,7 @@ This is similar to the flat mode, in that all instances are attached to the same VLAN DHCP Mode ~~~~~~~~~~~~~~ -This is the default networking mode and supports the most features.

All of the major nova components can be run on multiple servers. This means that most component to component communication must go via message queue. In order to avoid blocking each component while waiting for a response, we use deferred objects, with a callback that gets triggered when a response is received. -In order to achieve shared-nothing with multiple copies of the same component (especially when the component is an API server that needs to reply with state information in a timely fashion), we need to keep all of our system state in a distributed data system. Updates to system state are written into this system, using atomic transactions when necessary. Requests for state are read out of this system. In limited cases, these read calls are memoized within controllers for short periods of time. (Such a limited case would be, for instance, the current list of system users.) - +Nova recently moved to using a sql-based central database that is shared by all components in the system. The amount and depth of the data fits into a sql database quite well. For small deployments this seems like an optimal solution. For larger deployments, and especially if security is a concern, nova will be moving towards multiple data stores with some kind of aggregation system.

See the + License for the specific language governing permissions and limitations + under the License. + +Getting Started with Nova +========================= + +This code base is continually changing, so dependencies also change. If you +encounter any problems, see the :doc:`../reaching.out` page. +The `contrib/nova.sh` script should be kept up to date, and may be a good +resource to review when debugging. + +The purpose of this document is to get a system installed that you can use to +test your setup assumptions. Working from this base installtion you can +tweak configurations and work with different flags to monitor interaction with +your hardware, network, and other factors that will allow you to determine +suitability for your deployment. After following this setup method, you should +be able to experiment with different managers, drivers, and flags to get the +best performance. + +Dependencies +------------ + +Related servers we rely on + +* **RabbitMQ**: messaging queue, used for all communication between components + +Optional servers + +* **OpenLDAP**: By default, the auth server uses the RDBMS-backed datastore by + setting FLAGS.auth_driver to `nova.auth.dbdriver.DbDriver`. But OpenLDAP + (or LDAP) could be configured by specifying `nova.auth.ldapdriver.LdapDriver`. + There is a script in the sources (`nova/auth/slap.sh`) to install a very basic + openldap server on ubuntu. +* **ReDIS**: There is a fake ldap auth driver + `nova.auth.ldapdriver.FakeLdapDriver` that backends to redis. This was + created for testing ldap implementation on systems that don't have an easy + means to install ldap. +* **MySQL**: Either MySQL or another database supported by sqlalchemy needs to + be avilable. Currently, only sqlite3 an mysql have been tested. + +Python libraries that we use (from pip-requires): + +.. literalinclude:: ../../../tools/pip-requires + +Other libraries: + +* **XenAPI**: Needed only for Xen Cloud Platform or XenServer support. Available + from http://wiki.xensource.com/xenwiki/XCP_SDK or + http://community.citrix.com/cdn/xs/sdks. + +External unix tools that are required: + +* iptables +* ebtables +* gawk +* curl +* kvm +* libvirt +* dnsmasq +* vlan +* open-iscsi and iscsitarget (if you use iscsi volumes) +* aoetools and vblade-persist (if you use aoe-volumes) + +Nova uses cutting-edge versions of many packages. There are ubuntu packages in +the nova-core ppa. You can use add this ppa to your sources list on an ubuntu +machine with the following commands:: + + sudo apt-get install -y python-software-properties + sudo add-apt-repository ppa:nova-core/ppa + +Recommended +----------- + +* euca2ools: python implementation of aws ec2-tools and ami tools +* build tornado to use C module for evented section + + +Installation +-------------- + +You can install from packages for your particular Linux distribution if they are +available. Otherwise you can install from source by checking out the source +files from the `Nova Source Code Repository `_ +and running:: + + python setup.py install + +Configuration +--------------- + +Configuring the host system +~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +As you read through the Administration Guide you will notice configuration hints +inline with documentation on the subsystem you are configuring. Presented in +this "Getting Started with Nova" document, we only provide what you need to +get started as quickly as possible. For a more detailed description of system +configuration, start reading through :doc:`multi.node.install`. + +* Create a volume group (you can use an actual disk for the volume group as + well):: + + # This creates a 1GB file to create volumes out of + dd if=/dev/zero of=MY_FILE_PATH bs=100M count=10 + losetup --show -f MY_FILE_PATH + # replace /dev/loop0 below with whatever losetup returns + # nova-volumes is the default for the --volume_group flag + vgcreate nova-volumes /dev/loop0 + + +Configuring Nova +~~~~~~~~~~~~~~~~ + +Configuration of the entire system is performed through python-gflags. The +best way to track configuration is through the use of a flagfile. + +A flagfile is specified with the ``--flagfile=FILEPATH`` argument to the binary +when you launch it. Flagfiles for nova are typically stored in +``/etc/nova/nova.conf``, and flags specific to a certain program are stored in +``/etc/nova/nova-COMMAND.conf``. Each configuration file can include another +flagfile, so typically a file like ``nova-manage.conf`` would have as its first +line ``--flagfile=/etc/nova/nova.conf`` to load the common flags before +specifying overrides or additional options. + +A sample configuration to test the system follows:: + + --verbose + --nodaemon + --FAKE_subdomain=ec2 + --auth_driver=nova.auth.dbdriver.DbDriver + +Running +--------- + +There are many parts to the nova system, each with a specific function. They +are built to be highly-available, so there are may configurations they can be +run in (ie: on many machines, many listeners per machine, etc). This part +of the guide only gets you started quickly, to learn about HA options, see +:doc:`multi.node.install`. + +Launch supporting services + +* rabbitmq +* redis (optional) +* mysql (optional) + +Launch nova components, each should have ``--flagfile=/etc/nova/nova.conf`` + +* nova-api +* nova-compute +* nova-objectstore +* nova-volume +* nova-scheduler diff --git a/doc/source/adminguide/index.rst b/doc/source/adminguide/index.rst new file mode 100644 index 000000000..ad1788b8b --- /dev/null +++ b/doc/source/adminguide/index.rst @@ -0,0 +1,36 @@ +.. + Copyright 2010 United States Government as represented by the + Administrator of the National Aeronautics and Space Administration. + All Rights Reserved. + + Licensed under the Apache License, Version 2.0 (the "License"); you may + not use this file except in compliance with the License.

All of the major nova components can be run on multiple servers. This means that most component to component communication must go via message queue. In order to avoid blocking each component while waiting for a response, we use deferred objects, with a callback that gets triggered when a response is received. - -Nova recently moved to using a sql-based central database that is shared by all components in the system. The amount and depth of the data fits into a sql database quite well. For small deployments this seems like an optimal solution. For larger deployments, and especially if security is a concern, nova will be moving towards multiple data stores with some kind of aggregation system. - -Components ----------- - -Below you will find a helpful explanation of the different components. - -:: - - /- ( LDAP ) - [ Auth Manager ] --- - | \- ( DB ) - | - | [ scheduler ] - [ volume ] - ( ATAoE/iSCSI ) - | / - [ Web Dashboard ] -> [ api ] -- < AMQP > ------ [ network ] - ( Flat/Vlan ) - | \ - < HTTP > [ scheduler ] - [ compute ] - ( libvirt/xen ) - | | - [ objectstore ] < - retrieves images - -* DB: sql database for data storage.

The APIs can be logically grouped into sets that align with five typical roles: - -* Base User -* System Administrator/Developer (currently have the same permissions) -* Network Administrator -* Project Manager -* Cloud Administrator/IT-Security (currently have the same permissions) - -There is an additional, conceptual end-user that may or may not have API access: - -* (EXTERNAL) End-user / Third-party User - -Basic operations are available to any : - -* Describe Instances -* Describe Images -* Describe Volumes -* Describe Keypairs -* Create Keypair -* Delete Keypair -* Create, Upload, Delete: Buckets and Keys (Object Store) - -System Administrators/Developers/Project Manager: - -* Create, Attach, Delete Volume (Block Store) -* Launch, Reboot, Terminate Instance -* Register/Unregister Machine Image (project-wide) -* Request / Review CloudAudit Scans - -Project Manager: - -* Add and remove other users (currently no api) -* Set roles (currently no api) - -Network Administrator: - -* Change Machine Image properties (public / private) -* Change Firewall Rules, define Security Groups -* Allocate, Associate, Deassociate Public IP addresses - -Cloud Administrator/IT-Security: - -* All permissions - -Enhancements ------------- - -* SAML Token passing -* REST interfaces -* SOAP interfaces - -Wrapping the SAML token into the API calls. -Then store the UID (fetched via backchannel) into the instance metadata, providing end-to-end auditability of ownership and responsibility, without PII. - -CloudAudit APIs ---------------- - -* Request formats -* Response formats -* Stateless asynchronous queries - -CloudAudit queries may spawn long-running processes (similar to launching instances, etc.) They need to return a ReservationId in the same fashion, which can be returned in further queries for updates. -RBAC of CloudAudit API calls is critical, since detailed system information is a system vulnerability. - -Type declarations ------------------ -* Data declarations – Volumes and Objects -* System declarations – Instances - -Existing API calls to launch instances specific a single, combined “type” flag. We propose to extend this with three additional type declarations, mapping to the “Confidentiality, Integrity, Availability” classifications of FIPS 199. An example API call would look like:: - - RunInstances type=m1.large number=1 secgroup=default key=mykey confidentiality=low integrity=low availability=low - -These additional parameters would also apply to creation of block storage volumes (along with the existing parameter of ‘size’), and creation of object storage ‘buckets’. (C.I.A. classifications on a bucket would be inherited by the keys within this bucket.) - -Request Brokering ------------------ - - * Cloud Interop - * IMF Registration / PubSub - * Digital C&A - -Establishing declarative semantics for individual API calls will allow the cloud environment to seamlessly proxy these API calls to external, third-party vendors – when the requested CIA levels match. - -See related work within the Infrastructure 2.0 working group for more information on how the IMF Metadata specification could be utilized to manage registration of these vendors and their C&A credentials. - -Dirty Cloud – Hybrid Data Centers ---------------------------------- - -* CloudAudit bridge interfaces -* Anything in the ARP table - -A hybrid cloud environment provides dedicated, potentially co-located physical hardware with a network interconnect to the project or users’ cloud virtual network. - -This interconnect is typically a bridged VPN connection.

Access to this vpn is provided through a public port on the network host for the project. This allows users to have free access to the virtual machines in their project without exposing those machines to the public internet. - -Cloudpipe Image ---------------- - -The cloudpipe image is basically just a linux instance with openvpn installed. It needs a simple script to grab user data from the metadata server, b64 decode it into a zip file, and run the autorun.sh script from inside the zip. The autorun script will configure and run openvpn to run using the data from nova. - -It is also useful to have a cron script that will periodically redownload the metadata and copy the new crl. This will keep revoked users from connecting and will disconnect any users that are connected with revoked certificates when their connection is renegotiated (every hour). - -Cloudpipe Launch ----------------- - -When you use nova-manage to launch a cloudpipe for a user, it goes through the following process: - -#. creates a keypair called -vpn and saves it in the keys directory -#. creates a security group -vpn and opens up 1194 and icmp -#. creates a cert and private key for the vpn instance and saves it in the CA/projects// directory -#. zips up the info and puts it b64 encoded as user data -#. launches an m1.tiny instance with the above settings using the flag-specified vpn image - -Vpn Access ----------- - -In vlan networking mode, the second ip in each private network is reserved for the cloudpipe instance. This gives a consistent ip to the instance so that nova-network can create forwarding rules for access from the outside world. The network for each project is given a specific high-numbered port on the public ip of the network host. This port is automatically forwarded to 1194 on the vpn instance. - -If specific high numbered ports do not work for your users, you can always allocate and associate a public ip to the instance, and then change the vpn_public_ip and vpn_public_port in the database. This will be turned into a nova-manage command or a flag soon. - - -Certificates and Revocation ---------------------------- - -If the use_project_ca flag is set (required to for cloudpipes to work securely), then each project has its own ca. This ca is used to sign the certificate for the vpn, and is also passed to the user for bundling images. When a certificate is revoked using nova-manage, a new Certificate Revocation List (crl) is generated. As long as cloudpipe has an updated crl, it will block revoked users from connecting to the vpn. - -The :mod:`cloudpipe` Module -~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -.. automodule:: nova.cloudpipe.pipelib - :members: - :undoc-members: - :show-inheritance: - -The :mod:`crypto` Module -~~~~~~~~~~~~~~~~~~~~~~~~ - -.. automodule:: nova.crypto - :members: - :undoc-members: - :show-inheritance: - diff --git a/doc/source/compute.rst b/doc/source/compute.rst deleted file mode 100644 index e4c6c6ae7..000000000 --- a/doc/source/compute.rst +++ /dev/null @@ -1,146 +0,0 @@ -.. - Copyright 2010 United States Government as represented by the - Administrator of the National Aeronautics and Space Administration. - All Rights Reserved. - - Licensed under the Apache License, Version 2.0 (the "License"); you may - not use this file except in compliance with the License.

All of the major nova components can be run on multiple servers. This means that most component to component communication must go via message queue. In order to avoid blocking each component while waiting for a response, we use deferred objects, with a callback that gets triggered when a response is received. + +Nova recently moved to using a sql-based central database that is shared by all components in the system. The amount and depth of the data fits into a sql database quite well. For small deployments this seems like an optimal solution. For larger deployments, and especially if security is a concern, nova will be moving towards multiple data stores with some kind of aggregation system. + +Components +---------- + +Below you will find a helpful explanation of the different components. + +:: + + /- ( LDAP ) + [ Auth Manager ] --- + | \- ( DB ) + | + | [ scheduler ] - [ volume ] - ( ATAoE/iSCSI ) + | / + [ Web Dashboard ] -> [ api ] -- < AMQP > ------ [ network ] - ( Flat/Vlan ) + | \ + < HTTP > [ scheduler ] - [ compute ] - ( libvirt/xen ) + | | + [ objectstore ] < - retrieves images + +* DB: sql database for data storage.

We propose to extend this with three additional type declarations, mapping to the “Confidentiality, Integrity, Availability” classifications of FIPS 199. An example API call would look like:: + + RunInstances type=m1.large number=1 secgroup=default key=mykey confidentiality=low integrity=low availability=low + +These additional parameters would also apply to creation of block storage volumes (along with the existing parameter of ‘size’), and creation of object storage ‘buckets’.

Access to this vpn is provided through a public port on the network host for the project. This allows users to have free access to the virtual machines in their project without exposing those machines to the public internet. + +Cloudpipe Image +--------------- + +The cloudpipe image is basically just a linux instance with openvpn installed. It needs a simple script to grab user data from the metadata server, b64 decode it into a zip file, and run the autorun.sh script from inside the zip. The autorun script will configure and run openvpn to run using the data from nova. + +It is also useful to have a cron script that will periodically redownload the metadata and copy the new crl. This will keep revoked users from connecting and will disconnect any users that are connected with revoked certificates when their connection is renegotiated (every hour). + +Cloudpipe Launch +---------------- + +When you use nova-manage to launch a cloudpipe for a user, it goes through the following process: + +#. creates a keypair called -vpn and saves it in the keys directory +#. creates a security group -vpn and opens up 1194 and icmp +#. creates a cert and private key for the vpn instance and saves it in the CA/projects// directory +#. zips up the info and puts it b64 encoded as user data +#. launches an m1.tiny instance with the above settings using the flag-specified vpn image + +Vpn Access +---------- + +In vlan networking mode, the second ip in each private network is reserved for the cloudpipe instance. This gives a consistent ip to the instance so that nova-network can create forwarding rules for access from the outside world. The network for each project is given a specific high-numbered port on the public ip of the network host. This port is automatically forwarded to 1194 on the vpn instance. + +If specific high numbered ports do not work for your users, you can always allocate and associate a public ip to the instance, and then change the vpn_public_ip and vpn_public_port in the database. This will be turned into a nova-manage command or a flag soon. + + +Certificates and Revocation +--------------------------- + +If the use_project_ca flag is set (required to for cloudpipes to work securely), then each project has its own ca. This ca is used to sign the certificate for the vpn, and is also passed to the user for bundling images. When a certificate is revoked using nova-manage, a new Certificate Revocation List (crl) is generated. As long as cloudpipe has an updated crl, it will block revoked users from connecting to the vpn. + +The :mod:`cloudpipe` Module +~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +.. automodule:: nova.cloudpipe.pipelib + :members: + :undoc-members: + :show-inheritance: + +The :mod:`crypto` Module +~~~~~~~~~~~~~~~~~~~~~~~~ + +.. automodule:: nova.crypto + :members: + :undoc-members: + :show-inheritance: + diff --git a/doc/source/devguide/compute.rst b/doc/source/devguide/compute.rst new file mode 100644 index 000000000..e4c6c6ae7 --- /dev/null +++ b/doc/source/devguide/compute.rst @@ -0,0 +1,146 @@ +.. + Copyright 2010 United States Government as represented by the + Administrator of the National Aeronautics and Space Administration. + All Rights Reserved. + + Licensed under the Apache License, Version 2.0 (the "License"); you may + not use this file except in compliance with the License.

This document attempts to outline the division of responsibilities to make understanding the system a little bit easier. + +Currently, Managers and Drivers are specified by flags and loaded using utils.load_object(). This method allows for them to be implemented as singletons, classes, modules or objects. As long as the path specified by the flag leads to an object (or a callable that returns an object) that responds to getattr, it should work as a manager or driver. + +Service +------- + +A service is a very thin wrapper around a Manager object. It exposes the manager's public methods to other components of the system via rpc. It will report state periodically to the database and is responsible for initiating any periodic tasts that need to be executed on a given host. + +The :mod:`service` Module +~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +.. automodule:: nova.service + :members: + :undoc-members: + :show-inheritance: + +Manager +------- + +Managers are responsible for a certain aspect of the sytem. It is a logical grouping of code relating to a portion of the system. In general other components should be using the manager to make changes to the components that it is responsible for. + +For example, other components that need to deal with volumes in some way, should do so by calling methods on the VolumeManager instead of directly changing fields in the database. This allows us to keep all of the code relating to volumes in the same place. + +We have adopted a basic strategy of Smart managers and dumb data, which means rather than attaching methods to data objects, components should call manager methods that act on the data. + +Methods on managers that can be executed locally should be called directly. If a particular method must execute on a remote host, this should be done via rpc to the service that wraps the manager + +Managers should be responsible for most of the db access, and non-implementation specific data. Anything implementation specific that can't be generalized should be done by the Driver. + +In general, we prefer to have one manager with multiple drivers for different implementations, but sometimes it makes sense to have multiple managers. You can think of it this way: Abstract different overall strategies at the manager level(FlatNetwork vs VlanNetwork), and different implementations at the driver level(LinuxNetDriver vs CiscoNetDriver). + +Managers will often provide methods for initial setup of a host or periodic tasksto a wrapping service. + +The :mod:`manager` Module +~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +.. automodule:: nova.manager + :members: + :undoc-members: + :show-inheritance: + +Driver +------ + +A manager will generally load a driver for some of its tasks. The driver is responsible for specific implementation details. Anything running shell commands on a host, or dealing with other non-python code should probably be happening in a driver. + +Drivers should minimize touching the database, although it is currently acceptable for implementation specific data. This may be reconsidered at some point. + +It usually makes sense to define an Abstract Base Class for the specific driver (i.e. VolumeDriver), to define the methods that a different driver would need to implement. diff --git a/doc/source/devguide/volume.rst b/doc/source/devguide/volume.rst new file mode 100644 index 000000000..39b33a500 --- /dev/null +++ b/doc/source/devguide/volume.rst @@ -0,0 +1,62 @@ +.. + Copyright 2010 United States Government as represented by the + Administrator of the National Aeronautics and Space Administration. + All Rights Reserved. + + Licensed under the Apache License, Version 2.0 (the "License"); you may + not use this file except in compliance with the License.

This document attempts to outline the division of responsibilities to make understanding the system a little bit easier. - -Currently, Managers and Drivers are specified by flags and loaded using utils.load_object(). This method allows for them to be implemented as singletons, classes, modules or objects. As long as the path specified by the flag leads to an object (or a callable that returns an object) that responds to getattr, it should work as a manager or driver. - -Service -------- - -A service is a very thin wrapper around a Manager object. It exposes the manager's public methods to other components of the system via rpc. It will report state periodically to the database and is responsible for initiating any periodic tasts that need to be executed on a given host. - -The :mod:`service` Module -~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -.. automodule:: nova.service - :members: - :undoc-members: - :show-inheritance: - -Manager -------- - -Managers are responsible for a certain aspect of the sytem. It is a logical grouping of code relating to a portion of the system. In general other components should be using the manager to make changes to the components that it is responsible for. - -For example, other components that need to deal with volumes in some way, should do so by calling methods on the VolumeManager instead of directly changing fields in the database. This allows us to keep all of the code relating to volumes in the same place. - -We have adopted a basic strategy of Smart managers and dumb data, which means rather than attaching methods to data objects, components should call manager methods that act on the data. - -Methods on managers that can be executed locally should be called directly. If a particular method must execute on a remote host, this should be done via rpc to the service that wraps the manager - -Managers should be responsible for most of the db access, and non-implementation specific data. Anything implementation specific that can't be generalized should be done by the Driver. - -In general, we prefer to have one manager with multiple drivers for different implementations, but sometimes it makes sense to have multiple managers. You can think of it this way: Abstract different overall strategies at the manager level(FlatNetwork vs VlanNetwork), and different implementations at the driver level(LinuxNetDriver vs CiscoNetDriver). - -Managers will often provide methods for initial setup of a host or periodic tasksto a wrapping service. - -The :mod:`manager` Module -~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -.. automodule:: nova.manager - :members: - :undoc-members: - :show-inheritance: - -Driver ------- - -A manager will generally load a driver for some of its tasks. The driver is responsible for specific implementation details. Anything running shell commands on a host, or dealing with other non-python code should probably be happening in a driver. - -Drivers should minimize touching the database, although it is currently acceptable for implementation specific data. This may be reconsidered at some point. - -It usually makes sense to define an Abstract Base Class for the specific driver (i.e. VolumeDriver), to define the methods that a different driver would need to implement. diff --git a/doc/source/volume.rst b/doc/source/volume.rst deleted file mode 100644 index 39b33a500..000000000 --- a/doc/source/volume.rst +++ /dev/null @@ -1,62 +0,0 @@ -.. - Copyright 2010 United States Government as represented by the - Administrator of the National Aeronautics and Space Administration. - All Rights Reserved. - - Licensed under the Apache License, Version 2.0 (the "License"); you may - not use this file except in compliance with the License.

    Nova Daemons

    +

    The configuration of these binaries relies on “flagfiles” using the google +gflags package:

    +
    $ nova-xxxxx --flagfile flagfile
    +
    +

    The binaries can all run on the same machine or be spread out amongst multiple boxes in a large deployment.

    +
    +

    nova-api

    +

    Nova api receives xml requests and sends them to the rest of the system. It is a wsgi app that routes and authenticate requests. It supports the ec2 and openstack apis.

    +
    +
    +

    nova-objectstore

    +

    Nova objectstore is an ultra simple file-based storage system for images that replicates most of the S3 Api. It will soon be replaced with glance and a simple image manager.

    +
    +
    +

    nova-compute

    +

    Nova compute is responsible for managing virtual machines. It loads a Service object which exposes the public methods on ComputeManager via rpc.

    +
    +
    +

    nova-volume

    +

    Nova volume is responsible for managing attachable block storage devices. It loads a Service object which exposes the public methods on VolumeManager via rpc.

    +
    +
    +

    nova-network

    +

    Nova network is responsible for managing floating and fixed ips, dhcp, bridging and vlans. It loads a Service object which exposes the public methods on one of the subclasses of NetworkManager. Different networking strategies are as simple as changing the network_manager flag:

    +
    $ nova-network --network_manager=nova.network.manager.FlatManager
    +
    +

    IMPORTANT: Make sure that you also set the network_manager on nova-api and nova_compute, since make some calls to network manager in process instead of through rpc. More information on the interactions between services, managers, and drivers can be found here

    +
    + +
    +
    +
    +
    + +
    +

    Installation on other distros (like Debian, Fedora or CentOS )

    +

    Feel free to add additional notes for additional distributions.

    +
    +

    Nova installation on CentOS 5.5

    +

    These are notes for installing OpenStack Compute on CentOS 5.5 and will be updated but are NOT final. Please test for accuracy and edit as you see fit.

    +

    The principle botleneck for running nova on centos in python 2.6. Nova is written in python 2.6 and CentOS 5.5. comes with python 2.4. We can not update python system wide as some core utilities (like yum) is dependent on python 2.4. Also very few python 2.6 modules are available in centos/epel repos.

    +
    +
    +

    Pre-reqs

    +

    Add euca2ools and EPEL repo first.:

    +
    cat >/etc/yum.repos.d/euca2ools.repo << EUCA_REPO_CONF_EOF
+[eucalyptus]
+name=euca2ools
+baseurl=http://www.eucalyptussoftware.com/downloads/repo/euca2ools/1.3.1/yum/centos/
+enabled=1
+gpgcheck=0
+
+EUCA_REPO_CONF_EOF
    +
    +
    rpm -Uvh 'http://download.fedora.redhat.com/pub/epel/5/i386/epel-release-5-4.noarch.rpm'
    +
    +

    Now install python2.6, kvm and few other libraries through yum:

    +
    yum -y  install dnsmasq  vblade kpartx kvm gawk iptables ebtables  bzr screen euca2ools  curl rabbitmq-server gcc gcc-c++ autoconf automake swig  openldap openldap-servers nginx  python26 python26-devel python26-distribute git openssl-devel  python26-tools mysql-server qemu kmod-kvm libxml2 libxslt libxslt-devel mysql-devel
    +
    +

    Then download the latest aoetools and then build(and install) it, check for the latest version on sourceforge, exact url will change if theres a new release:

    +
    wget -c http://sourceforge.net/projects/aoetools/files/aoetools/32/aoetools-32.tar.gz/download
+tar -zxvf aoetools-32.tar.gz
+cd aoetools-32
+make
+make install
    +
    +

    Add the udev rules for aoetools:

    +
    cat > /etc/udev/rules.d/60-aoe.rules << AOE_RULES_EOF
+SUBSYSTEM=="aoe", KERNEL=="discover",    NAME="etherd/%k", GROUP="disk", MODE="0220"
+SUBSYSTEM=="aoe", KERNEL=="err",    NAME="etherd/%k", GROUP="disk", MODE="0440"
+SUBSYSTEM=="aoe", KERNEL=="interfaces",    NAME="etherd/%k", GROUP="disk", MODE="0220"
+SUBSYSTEM=="aoe", KERNEL=="revalidate",    NAME="etherd/%k", GROUP="disk", MODE="0220"
+# aoe block devices
+KERNEL=="etherd*",       NAME="%k", GROUP="disk"
+AOE_RULES_EOF
    +
    +

    Load the kernel modules:

    +
    modprobe aoe
    +
    +
    modprobe kvm
    +
    +

    Now, install the python modules using easy_install-2.6, this ensures the installation are done against python 2.6

    +

    easy_install-2.6 twisted sqlalchemy mox greenlet carrot daemon eventlet tornado IPy routes lxml MySQL-python +python-gflags need to be downloaded and installed manually, use these commands (check the exact url for newer releases ):

    +
    wget -c "http://python-gflags.googlecode.com/files/python-gflags-1.4.tar.gz"
+tar -zxvf python-gflags-1.4.tar.gz
+cd python-gflags-1.4
+python2.6 setup.py install
+cd ..
    +
    +

    Same for python2.6-libxml2 module, notice the –with-python and –prefix flags. –with-python ensures we are building it against python2.6 (otherwise it will build against python2.4, which is default):

    +
    wget -c "ftp://xmlsoft.org/libxml2/libxml2-2.7.3.tar.gz"
+tar -zxvf libxml2-2.7.3.tar.gz
+cd libxml2-2.7.3
+./configure --with-python=/usr/bin/python26 --prefix=/usr
+make all
+make install
+cd python
+python2.6 setup.py install
+cd ..
    +
    +

    + +
    +

    Installing on Ubuntu 10.04 (Lucid)

    +
    +

    Step 1: Install dependencies

    +

    Grab the latest code from launchpad:

    +
    bzr clone lp:nova
    +
    +

    Here’s a script you can use to install (and then run) Nova on Ubuntu or Debian (when using Debian, edit nova.sh to have USE_PPA=0):

    +
    +

    Todo

    +

    give a link to a stable releases page

    +
    +
    +
    +

    Step 2: Install dependencies

    +

    Nova requires rabbitmq for messaging and optionally you can use redis for storing state, so install these first.

    +

    Note: You must have sudo installed to run these commands as shown here.

    +
    sudo apt-get install rabbitmq-server redis-server
    +
    +

    You’ll see messages starting with “Reading package lists... Done” and you must confirm by typing Y that you want to continue.

    +

    If you’re running on Ubuntu 10.04, you’ll need to install Twisted and python-gflags which is included in the OpenStack PPA.

    +
    sudo apt-get install python-twisted
+
+sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 95C71FE2
+sudo sh -c 'echo "deb http://ppa.launchpad.net/openstack/openstack-ppa/ubuntu lucid main" > /etc/apt/sources.list.d/openstackppa.list'
+sudo apt-get update && sudo apt-get install python-gflags
    +
    +

    Once you’ve done this, continue at Step 3 here: Installing Nova on a Single Host

    Installing on Ubuntu 10.10 (Maverick)

    +

    Single Machine Installation (Ubuntu 10.10)

    +

    While we wouldn’t expect you to put OpenStack Compute into production on a non-LTS version of Ubuntu, these instructions are up-to-date with the latest version of Ubuntu.

    +

    Make sure you are running Ubuntu 10.10 so that the packages will be available. This install requires more than 70 MB of free disk space.

    +

    These instructions are based on Soren Hansen’s blog entry, Openstack on Maverick. A script is in progress as well.

    +
    +

    Step 1: Install required prerequisites

    +

    Nova requires rabbitmq for messaging and redis for storing state (for now), so we’ll install these first.:

    +
    sudo apt-get install rabbitmq-server redis-server
    +
    +

    You’ll see messages starting with “Reading package lists... Done” and you must confirm by typing Y that you want to continue.

    +
    +
    +

    Step 2: Install Nova packages available in Maverick Meerkat

    +

    Type or copy/paste in the following line to get the packages that you use to run OpenStack Compute.:

    +
    sudo apt-get install python-nova
+sudo apt-get install nova-api nova-objectstore nova-compute nova-scheduler nova-network euca2ools unzip
    +
    +

    You’ll see messages starting with “Reading package lists... Done” and you must confirm by typing Y that you want to continue. This operation may take a while as many dependent packages will be installed. Note: there is a dependency problem with python-nova which can be worked around by installing first.

    +

    When the installation is complete, you’ll see the following lines confirming::

    +
    Adding system user `nova' (UID 106) ...
+Adding new user `nova' (UID 106) with group `nogroup' ...
+Not creating home directory `/var/lib/nova'.
+Setting up nova-scheduler (0.9.1~bzr331-0ubuntu2) ...
+ * Starting nova scheduler nova-scheduler
+WARNING:root:Starting scheduler node
+   ...done.
+Processing triggers for libc-bin ...
+ldconfig deferred processing now taking place
+Processing triggers for python-support ...
    +
    +

    Once you’ve done this, continue at Step 3 here: Installing Nova on a Single Host

    Getting Started with Nova

    +

    This code base is continually changing, so dependencies also change. If you +encounter any problems, see the Getting Involved page. +The contrib/nova.sh script should be kept up to date, and may be a good +resource to review when debugging.

    +

    The purpose of this document is to get a system installed that you can use to +test your setup assumptions. Working from this base installtion you can +tweak configurations and work with different flags to monitor interaction with +your hardware, network, and other factors that will allow you to determine +suitability for your deployment. After following this setup method, you should +be able to experiment with different managers, drivers, and flags to get the +best performance.

    +
    +

    Dependencies

    +

    Related servers we rely on

    +
      +
    • RabbitMQ: messaging queue, used for all communication between components
      • +
    +

    Optional servers

    +
      +
    • OpenLDAP: By default, the auth server uses the RDBMS-backed datastore by +setting FLAGS.auth_driver to nova.auth.dbdriver.DbDriver. But OpenLDAP +(or LDAP) could be configured by specifying nova.auth.ldapdriver.LdapDriver. +There is a script in the sources (nova/auth/slap.sh) to install a very basic +openldap server on ubuntu.
      • +
    • ReDIS: There is a fake ldap auth driver +nova.auth.ldapdriver.FakeLdapDriver that backends to redis. This was +created for testing ldap implementation on systems that don’t have an easy +means to install ldap.
      • +
    • MySQL: Either MySQL or another database supported by sqlalchemy needs to +be avilable. Currently, only sqlite3 an mysql have been tested.
      • +
    +

    Python libraries that we use (from pip-requires):

    +
    SQLAlchemy==0.6.3
+pep8==0.5.0
+pylint==0.19
+IPy==0.70
+M2Crypto==0.20.2

      • +
    • ebtables
      • +
    • gawk
      • +

      • +
    • aoetools and vblade-persist (if you use aoe-volumes)
      • +
    +

    Nova uses cutting-edge versions of many packages. There are ubuntu packages in +the nova-core ppa. You can use add this ppa to your sources list on an ubuntu +machine with the following commands:

    +
    sudo apt-get install -y python-software-properties
+sudo add-apt-repository ppa:nova-core/ppa
    +
    +
    + +
    +

    Installation

    +

    You can install from packages for your particular Linux distribution if they are +available. Otherwise you can install from source by checking out the source +files from the Nova Source Code Repository +and running:

    +
    python setup.py install
    +
    +
    +
    +

    Configuration

    +
    +

    Configuring the host system

    +

    As you read through the Administration Guide you will notice configuration hints +inline with documentation on the subsystem you are configuring. Presented in +this “Getting Started with Nova” document, we only provide what you need to +get started as quickly as possible. For a more detailed description of system +configuration, start reading through Installing Nova on Multiple Servers.

    +
      +

    • Create a volume group (you can use an actual disk for the volume group as +well):

      +
      # This creates a 1GB file to create volumes out of
+dd if=/dev/zero of=MY_FILE_PATH bs=100M count=10
+losetup --show -f MY_FILE_PATH
+# replace /dev/loop0 below with whatever losetup returns
+# nova-volumes is the default for the --volume_group flag
+vgcreate nova-volumes /dev/loop0
      +
      +
      • +
    +
    +
    +

    Configuring Nova

    +

    Configuration of the entire system is performed through python-gflags. The +best way to track configuration is through the use of a flagfile.

    +

    A flagfile is specified with the --flagfile=FILEPATH argument to the binary +when you launch it. Flagfiles for nova are typically stored in +/etc/nova/nova.conf, and flags specific to a certain program are stored in +/etc/nova/nova-COMMAND.conf. Each configuration file can include another +flagfile, so typically a file like nova-manage.conf would have as its first +line --flagfile=/etc/nova/nova.conf to load the common flags before +specifying overrides or additional options.

    +

    A sample configuration to test the system follows:

    +
    --verbose
+--nodaemon
+--FAKE_subdomain=ec2
+--auth_driver=nova.auth.dbdriver.DbDriver
+
    +
    +
    +
    +
    +

    Running

    +

    There are many parts to the nova system, each with a specific function. They +are built to be highly-available, so there are may configurations they can be +run in (ie: on many machines, many listeners per machine, etc). This part +of the guide only gets you started quickly, to learn about HA options, see +Installing Nova on Multiple Servers.

    +

    Launch supporting services

    +
      +
    • rabbitmq
      • +
    • redis (optional)
      • +
    • mysql (optional)
      • +
    • openldap (optional)
      • +
    +

    Launch nova components, each should have --flagfile=/etc/nova/nova.conf

    Administration Guide

    +

    This guide describes the basics of running and managing Nova.

    +
    +

    Running the Cloud

    +

    The fastest way to get a test cloud running is by following the directions in the Nova Quickstart.

    +

    Nova’s cloud works via the interaction of a series of daemon processes that reside persistently on the host machine(s). Fortunately, the Nova Quickstart process launches sample versions of all these daemons for you. Once you are familiar with basic Nova usage, you can learn more about daemons by reading Service Architecture and Nova Daemons.

    +
    +
    +

    Administration Utilities

    +

    There are two main tools that a system administrator will find useful to manage their Nova cloud:

    +
    + +
    +

    nova-manage may only be run by users with admin priviledges. euca2ools can be used by all users, though specific commands may be restricted by Role Based Access Control. You can read more about creating and managing users in Managing Users

    +
    +
    +

    User and Resource Management

    +

    nova-manage and euca2ools provide the basic interface to perform a broad range of administration functions. In this section, you can read more about how to accomplish specific administration tasks.

    Keypairs

    +

    Images can be shared by many users, so it is dangerous to put passwords into the images. Nova therefore supports injecting ssh keys into instances before they are booted. This allows a user to login to the instances that he or she creates securely. Generally the first thing that a user does when using the system is create a keypair. Nova generates a public and private key pair, and sends the private key to the user. The public key is stored so that it can be injected into instances.

    +

    Keypairs are created through the api. They can be created on the command line using the euca2ools script euca-add-keypair. Refer to the man page for the available options. Example usage:

    +
    euca-add-keypair test > test.pem
+chmod 600 test.pem
+euca-run-instances -k test -t m1.tiny ami-tiny
+# wait for boot
+ssh -i test.pem root@ip.of.instance
    +
    +
    +
    +

    Basic Management

    +

    Instance management can be accomplished with euca commands:

    +

    To run an instance:

    +
    euca-run-instances
+
    +
    +

    To terminate an instance:

    +
    euca-terminate-instances
+
    +
    +

    To reboot an instance:

    +
    euca-reboot-instances
+
    +
    +

    See the euca2ools documentation for more information

    Networking Overview

    +

    In Nova, users organize their cloud resources in projects. A Nova project consists of a number of VM instances created by a user. For each VM instance, Nova assigns to it a private IP address. (Currently, Nova only supports Linux bridge networking that allows the virtual interfaces to connect to the outside network through the physical interface. Other virtual network technologies, such as Open vSwitch, could be supported in the future.) The Network Controller provides virtual networks to enable compute servers to interact with each other and with the public network.

    Nova Network Strategies

    +

    Currently, Nova supports three kinds of networks, implemented in three “Network Manager” types respectively: Flat Network Manager, Flat DHCP Network Manager, and VLAN Network Manager. The three kinds of networks can c-exist in a cloud system. However, the scheduler for selecting the type of network for a given project is not yet implemented. Here is a brief description of each of the different network strategies, with a focus on the VLAN Manager in a separate section.

    Managing Projects

    +

    Projects are isolated resource containers forming the principal organizational structure within Nova. They consist of a separate vlan, volumes, instances, images, keys, and users.

    +

    Although the original ec2 api only supports users, nova adds the concept of projects. A user can specify which project he or she wishes to use by appending :project_id to his or her access key. If no project is specified in the api request, nova will attempt to use a project with the same id as the user.

    +

    The api will return NotAuthorized if a normal user attempts to make requests for a project that he or she is not a member of. Note that admins or users with special admin roles skip this check and can make requests for any project.

    +
    +
    To create a project, use the project create command of nova-manage. The syntax is nova-manage project create projectname manager_id [description] You must specify a projectname and a manager_id. For example::
    +
    nova-manage project create john_project john “This is a sample project”
    +
    You can add and remove users from projects with project add and project remove::
    +
    nova-manage project add john_project john +nova-manage project remove john_project john
    +
    +
    +

    Project Commands

    +

    Admins and Project Managers can use the ‘nova-manage project’ command to manage project resources:

    +
      +
    • +

    Setting Quotas

    +

    Nova utilizes a quota system at the project level to control resource consumption across available hardware resources. Current quota controls are available to limit the:

    +
      +
    • Number of volumes which may be created
      • +
    • Total size of all volumes within a project as measured in GB
      • +
    • Number of instances which may be launched
      • +
    • Number of processor cores which may be allocated
      • +
    • Publicly accessible IP addresses
      • +
    +

    Use the following command to set quotas for a project +* project quota: Set or display quotas for project

    +
    +
      +
    • arguments: project_id [key] [value]
      • +
    +

    +
    +

    Users and Access Keys

    +

    Access to the ec2 api is controlled by an access and secret key. The user’s access key needs to be included in the request, and the request must be signed with the secret key. Upon receipt of api requests, nova will verify the signature and execute commands on behalf of the user.

    +

    In order to begin using nova, you will need a to create a user. This can be easily accomplished using the user create or user admin commands in nova-manage. user create will create a regular user, whereas user admin will create an admin user. The syntax of the command is nova-manage user create username [access] [secret]. For example:

    +
    nova-manage user create john my-access-key a-super-secret-key
    +
    +

    If you do not specify an access or secret key, a random uuid will be created automatically.

    +
    +
    +

    Credentials

    +

    Nova can generate a handy set of credentials for a user. These credentials include a CA for bundling images and a file for setting environment variables to be used by euca2ools. If you don’t need to bundle images, just the environment script is required. You can export one with the project environment command. The syntax of the command is nova-manage project environment project_id user_id [filename]. If you don’t specify a filename, it will be exported as novarc. After generating the file, you can simply source it in bash to add the variables to your environment:

    +
    nova-manage project environment john_project john
+. novarc
    +
    +

    If you do need to bundle images, you will need to get all of the credentials using project zipfile. Note that zipfile will give you an error message if networks haven’t been created yet. Otherwise zipfile has the same syntax as environment, only the default file name is nova.zip. Example usage:

    +
    nova-manage project zipfile john_project john
+unzip nova.zip
+. novarc
    +
    +
    +
    +

    Role Based Access Control

    +

    Roles control the api actions that a user is allowed to perform. For example, a user cannot allocate a public ip without the netadmin role. It is important to remember that a users de facto permissions in a project is the intersection of user (global) roles and project (local) roles. So for john to have netadmin permissions in his project, he needs to separate roles specified. You can add roles with role add. The syntax is nova-manage role add user_id role [project_id]. Let’s give john the netadmin role for his project:

    +
    nova-manage role add john netadmin
+nova-manage role add john netadmin john_project
    +
    +

    Role-based access control (RBAC) is an approach to restricting system access to authorized users based on an individual’s role within an organization. Various employee functions require certain levels of system access in order to be successful. These functions are mapped to defined roles and individuals are categorized accordingly. Since users are not assigned permissions directly, but only acquire them through their role (or roles), management of individual user rights becomes a matter of assigning appropriate roles to the user. This simplifies common operations, such as adding a user, or changing a user’s department.

    +

    Nova’s rights management system employs the RBAC model and currently supports the following five roles:

    +
      +
    • Cloud Administrator. (admin) Users of this class enjoy complete system access.
      • +
    • IT Security. (itsec) This role is limited to IT security personnel. It permits role holders to quarantine instances.
      • +
    • Project Manager. (projectmanager)The default for project owners, this role affords users the ability to add other users to a project, interact with project images, and launch and terminate instances.
      • +
    • Network Administrator. (netadmin) Users with this role are permitted to allocate and assign publicly accessible IP addresses as well as create and modify firewall rules.
      • +
    • Developer. This is a general purpose role that is assigned to users by default.
      • +
    +

    RBAC management is exposed through the dashboard for simplified user management.

    +
    +

    User Commands

    +

    Users, including admins, are created through the user commands.

    +

    Security Considerations

    +
    +

    Todo

    +

    This doc is vague and just high-level right now. Describe architecture that enables security.

    +
    +

    The goal of securing a cloud computing system involves both protecting the instances, data on the instances, and +ensuring users are authenticated for actions and that borders are understood by the users and the system. +Protecting the system from intrusion or attack involves authentication, network protections, and +compromise detection.

    +
    +

    Key Concepts

    +

    Authentication - Each instance is authenticated with a key pair.

    +

    Network - Instances can communicate with each other but you can configure the boundaries through firewall +configuration.

    +

    Monitoring - Log all API commands and audit those logs.

    +

    Encryption - Data transfer between instances is not encrypted.

    Installing Nova on Multiple Servers

    +

    When you move beyond evaluating the technology and into building an actual +production environemnt, you will need to know how to configure your datacenter +and how to deploy components across your clusters. This guide should help you +through that process.

    +

    You can install multiple nodes to increase performance and availability of the OpenStack Compute installation.

    +

    This setup is based on an Ubuntu Lucid 10.04 installation with the latest updates. Most of this works around issues that need to be resolved in the installation and configuration scripts as of October 18th 2010. It also needs to eventually be generalized, but the intent here is to get the multi-node configuration bootstrapped so folks can move forward.

    +
    +

    Requirements for a multi-node installation

    +
      +
    • You need a real database, compatible with SQLAlchemy (mysql, postgresql) There’s not a specific reason to choose one over another, it basically depends what you know. MySQL is easier to do High Availability (HA) with, but people may already know Postgres. We should document both configurations, though.
      • +
    • For a recommended HA setup, consider a MySQL master/slave replication, with as many slaves as you like, and probably a heartbeat to kick one of the slaves into being a master if it dies.
      • +
    • For performance optimization, split reads and writes to the database. MySQL proxy is the easiest way to make this work if running MySQL.
      • +
    +
    +

    Assumptions

    +
      +
    • Networking is configured between/through the physical machines on a single subnet.
      • +
    • Installation and execution are both performed by root user.
      • +
    +
    +
    +
    +

    Step 1 Use apt-get to get the latest code

    +
      +
    1. Setup Nova PPA with https://launchpad.net/~nova-core/+archive/ppa.
      2. +
    +
    sudo apt-get install python-software-properties
+sudo add-apt-repository ppa:nova-core/ppa
    +
    +
      +
    1. Run update.
      2. +
    +
    sudo apt-get update
    +
    +
      +
    1. Install nova-pkgs (dependencies should be automatically installed).
      2. +
    +
    sudo apt-get install python-greenlet
+sudo apt-get install nova-common nova-doc python-nova nova-api nova-network nova-objectstore nova-scheduler
    +
    +

    It is highly likely that there will be errors when the nova services come up since they are not yet configured. Don’t worry, you’re only at step 1!

    +
    +
    +

    Step 2 Setup configuration files (installed in /etc/nova)

    +

    Note: CC_ADDR=<the external IP address of your cloud controller>

    +
      +
    1. These need to be defined in EACH configuration file
      2. +
    +
    --sql_connection=mysql://root:nova@$CC_ADDR/nova # location of nova sql db
+--s3_host=$CC_ADDR  # This is where nova is hosting the objectstore service, which
+                    # will contain the VM images and buckets
+--rabbit_host=$CC_ADDR # This is where the rabbit AMQP messaging service is hosted
+--cc_host=$CC_ADDR     # This is where the the nova-api service lives
+--verbose              # Optional but very helpful during initial setup
+--ec2_url=http://$CC_ADDR:8773/services/Cloud
+--network_manager=nova.network.manager.FlatManager # simple, no-vlan networking type
    +
    +
      +
    1. nova-manage specific flags
      2. +
    +
    --FAKE_subdomain=ec2             # workaround for ec2/euca api
+--fixed_range=<network/prefix>   # ip network to use for VM guests, ex 192.168.2.64/26
+--network_size=<# of addrs>      # number of ip addrs to use for VM guests, ex 64
    +
    +
      +
    1. nova-network specific flags
      2. +
    +
    --fixed_range=<network/prefix>   # ip network to use for VM guests, ex 192.168.2.64/26
+--network_size=<# of addrs>      # number of ip addrs to use for VM guests, ex 64
    +
    +
      +
    1. nova-api specific flags
      2. +
    +
    --FAKE_subdomain=ec2             # workaround for ec2/euca api
+
    +
    +
      +
    1. Create a nova group
      2. +
    +
    sudo addgroup nova
    +
    +
      +
    1. nova-objectstore specific flags < no specific config needed >
      2. +
    +

    Config files should be have their owner set to root:nova, and mode set to 0640, since they contain your MySQL server’s root password.

    +
    cd /etc/nova
+chown -R root:nova .
    +
    +
    +
    +

    Step 3 Setup the sql db

    +
      +
    1. First you ‘preseed’ (using vishy’s Nova Quickstart). Run this as root.
      2. +
    +
    sudo apt-get install bzr git-core
+sudo bash
+export MYSQL_PASS=nova
    +
    +
    cat <<MYSQL_PRESEED | debconf-set-selections
+mysql-server-5.1 mysql-server/root_password password $MYSQL_PASS
+mysql-server-5.1 mysql-server/root_password_again password $MYSQL_PASS
+mysql-server-5.1 mysql-server/start_on_boot boolean true
+MYSQL_PRESEED
    +
    +
      +
    1. Install mysql
      2. +
    +
    sudo apt-get install -y mysql-server
    +
    +
      +
    1. Edit /etc/mysql/my.cnf and set this line: bind-address=0.0.0.0 and then sighup or restart mysql
      2. +
    2. create nova’s db
      3. +
    +
    mysql -uroot -pnova -e 'CREATE DATABASE nova;'
    +
    +
      +
    1. Update the db to include user ‘root’@’%’
      2. +
    +
    mysql -u root -p nova
+GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' WITH GRANT OPTION;
+SET PASSWORD FOR 'root'@'%' = PASSWORD('nova');
    +
    +
      +
    1. branch and install Nova
      2. +
    +
    sudo -i
+cd ~
+export USE_MYSQL=1
+export MYSQL_PASS=nova
+git clone https://github.com/vishvananda/novascript.git
+cd novascript
+./nova.sh branch
+./nova.sh install
+./nova.sh run
    +
    +
    +
    +

    Step 4 Setup Nova environment

    +
    /usr/bin/python /usr/bin/nova-manage user admin <user_name>
+/usr/bin/python /usr/bin/nova-manage project create <project_name> <user_name>
+/usr/bin/python /usr/bin/nova-manage project create network
    +
    +

    Note: The nova-manage service assumes that the first IP address is your network (like 192.168.0.0), that the 2nd IP is your gateway (192.168.0.1), and that the broadcast is the very last IP in the range you defined (192.168.0.255). If this is not the case you will need to manually edit the sql db ‘networks’ table.o.

    +

    On running this command, entries are made in the ‘networks’ and ‘fixed_ips’ table. However, one of the networks listed in the ‘networks’ table needs to be marked as bridge in order for the code to know that a bridge exists. We ended up doing this manually, (update query fired directly in the DB). Is there a better way to mark a network as bridged?

    +

    Update: This has been resolved w.e.f 27/10. network is marked as bridged automatically based on the type of n/w manager selected.

    +
    +

    More networking details to create a network bridge for flat network

    +

    Nova defaults to a bridge device named ‘br100’. This needs to be created and somehow integrated into YOUR network. In my case, I wanted to keep things as simple as possible and have all the vm guests on the same network as the vm hosts (the compute nodes). Thus, I set the compute node’s external IP address to be on the bridge and added eth0 to that bridge. To do this, edit your network interfaces config to look like the following:

    +
    < begin /etc/network/interfaces >
+# The loopback network interface
+auto lo
+iface lo inet loopback
+
+# Networking for NOVA
+auto br100
+
+iface br100 inet dhcp
+       bridge_ports    eth0
+       bridge_stp      off
+       bridge_maxwait  0
+       bridge_fd       0
+< end /etc/network/interfaces >
    +
    +

    Next, restart networking to apply the changes:

    +
    sudo /etc/init.d/networking restart
    +
    +
    +
    +
    +

    Step 5: Create nova certs.

    +

    Generate the certs as a zip file:

    +
    mkdir creds
+sudo /usr/bin/python /usr/bin/nova-manage project zip admin admin creds/nova.zip
    +
    +

    you can get the rc file more easily with:

    +
    sudo /usr/bin/python /usr/bin/nova-manage project env admin admin creds/novarc
    +
    +

    unzip them in your home directory, and add them to your environment:

    +
    unzip creds/nova.zip
+echo ". creds/novarc" >> ~/.bashrc
+~/.bashrc
    +
    +
    +
    +

    Step 6 Restart all relevant services

    +

    Restart Libvirt:

    +
    sudo /etc/init.d/libvirt-bin restart
    +
    +

    Restart relevant nova services:

    +
    sudo /etc/init.d/nova-compute restart
+sudo /etc/init.d/nova-volume restart
    +
    +
    +

    Flat Network Mode (Original and Flat)

    +

    Flat network mode removes most of the complexity of VLAN mode by simply +bridging all instance interfaces onto a single network.

    +

    There are two variations of flat mode that differ mostly in how IP addresses +are given to instances.

    +
    +

    Original Flat Mode

    +

    IP addresses for VM instances are grabbed from a subnet specified by the network administrator, and injected into the image on launch. All instances of the system are attached to the same Linux networking bridge, configured manually by the network administrator both on the network controller hosting the network and on the computer controllers hosting the instances. To recap:

    +
      +
    • Each compute host creates a single bridge for all instances to use to attach to the external network.
      • +
    • The networking configuration is injected into the instance before it is booted or it is obtained by a guest agent installed in the instance.
      • +
    +

    Note that the configuration injection currently only works on linux-style systems that keep networking +configuration in /etc/network/interfaces.

    +
    +
    +

    Flat DHCP Mode

    +

    IP addresses for VM instances are grabbed from a subnet specified by the network administrator. Similar to the flat network, a single Linux networking bridge is created and configured manually by the network administrator and used for all instances. A DHCP server is started to pass out IP addresses to VM instances from the specified subnet. To recap:

    +
      +
    • Like flat mode, all instances are attached to a single bridge on the compute node.
      • +
    • In addition a DHCP server is running to configure instances.
      • +
    +
    +
    +

    Implementation

    +

    The network nodes do not act as a default gateway in flat mode. Instances +are given public IP addresses.

    +

    Compute nodes have iptables/ebtables entries created per project and +instance to protect against IP/MAC address spoofing and ARP poisoning.

    +
    +

    VLAN Network Mode

    +

    VLAN Network Mode is the default mode for Nova. It provides a private network +segment for each project’s instances that can be accessed via a dedicated +VPN connection from the Internet.

    +

    In this mode, each project gets its own VLAN, Linux networking bridge, and subnet. The subnets are specified by the network administrator, and are assigned dynamically to a project when required. A DHCP Server is started for each VLAN to pass out IP addresses to VM instances from the subnet assigned to the project. All instances belonging to one project are bridged into the same VLAN for that project. The Linux networking bridges and VLANs are created by Nova when required, described in more detail in Nova VLAN Network Management Implementation.

    +
    +

    Todo

    +

    Insert Figure 2 from “An OpenStack Network Overview” contributed by Citrix

    +
    +

    While network traffic between VM instances belonging to the same VLAN is always open, Nova can enforce isolation of network traffic between different projects by enforcing one VLAN per project.

    +

    In addition, the network administrator can specify a pool of public IP addresses that users may allocate and then assign to VMs, either at boot or dynamically at run-time. This capability is similar to Amazon’s ‘elastic IPs’. A public IP address may be associated with a running instances, allowing the VM instance to be accessed from the public network. The public IP addresses are accessible from the network host and NATed to the private IP address of the project.

    +
    +

    Todo

    +

    Describe how a public IP address could be associated with a project (a VLAN)

    +
    +

    This is the default networking mode and supports the most features. For multiple machine installation, it requires a switch that supports host-managed vlan tagging. In this mode, nova will create a vlan and bridge for each project. The project gets a range of private ips that are only accessible from inside the vlan. In order for a user to access the instances in their project, a special vpn instance (code named cloudpipe) needs to be created. Nova generates a certificate and key for the user to access the vpn and starts the vpn automatically. More information on cloudpipe can be found here.

    +

    The following diagram illustrates how the communication that occurs between the vlan (the dashed box) and the public internet (represented by the two clouds)

    +../_images/cloudpipe.png +
    +

    Goals

    +
      +
    • each project is in a protected network segment
        +
      • RFC-1918 IP space
        • +
      • public IP via NAT
        • +
      • no default inbound Internet access without public NAT
        • +
      • limited (project-admin controllable) outbound Internet access
        • +
      • limited (project-admin controllable) access to other project segments
        • +
      • all connectivity to instance and cloud API is via VPN into the project segment
        • +
      +
      • +
    • common DMZ segment for support services (only visible from project segment)
        +
      • metadata
        • +
      • dashboard
        • +
      +
      • +
    +
    +
    +

    Limitations

    +
      +
    • Projects / cluster limited to available VLANs in switching infrastructure
      • +
    • Requires VPN for access to project segment
      • +
    +
    +
    +

    Implementation

    +

    Currently Nova segregates project VLANs using 802.1q VLAN tagging in the +switching layer. Compute hosts create VLAN-specific interfaces and bridges +as required.

    +

    The network nodes act as default gateway for project networks and contain +all of the routing and firewall rules implementing security groups. The +network node also handles DHCP to provide instance IPs for each project.

    +

    VPN access is provided by running a small instance called CloudPipe +on the IP immediately following the gateway IP for each project. The +network node maps a dedicated public IP/port to the CloudPipe instance.

    +

    Compute nodes have per-VLAN interfaces and bridges created as required. +These do NOT have IP addresses in the host to protect host access. +Compute nodes have iptables/ebtables entries created per project and +instance to protect against IP/MAC address spoofing and ARP poisoning.

    +

    The network assignment to a project, and IP address assignment to a VM instance, are triggered when a user starts to run a VM instance. When running a VM instance, a user needs to specify a project for the instances, and the security groups (described in Security Groups) when the instance wants to join. If this is the first instance to be created for the project, then Nova (the cloud controller) needs to find a network controller to be the network host for the project; it then sets up a private network by finding an unused VLAN id, an unused subnet, and then the controller assigns them to the project, it also assigns a name to the project’s Linux bridge, and allocating a private IP within the project’s subnet for the new instance.

    +

    If the instance the user wants to start is not the project’s first, a subnet and a VLAN must have already been assigned to the project; therefore the system needs only to find an available IP address within the subnet and assign it to the new starting instance. If there is no private IP available within the subnet, an exception will be raised to the cloud controller, and the VM creation cannot proceed.

    +
    +

    Todo

    +

    insert the name of the Linux bridge, is it always named bridge?

    +
    +
    +
    +

    External Infrastructure

    +

    Nova assumes the following is available:

    +
      +
    • DNS
      • +
    • NTP
      • +
    • Internet connectivity
      • +
    +
    +
    +

    Example

    +

    This example network configuration demonstrates most of the capabilities +of VLAN Mode. It splits administrative access to the nodes onto a dedicated +management network and uses dedicated network nodes to handle all +routing and gateway functions.

    +

    It uses a 10GB network for instance traffic and a 1GB network for management.

    +
    +

    Hardware

    +
      +
    • All nodes have a minimum of two NICs for management and production.
        +
      • management is 1GB
        • +
      • production is 10GB
        • +
      • add additional NICs for bonding or HA/performance
        • +
      +
      • +
    • network nodes should have an additional NIC dedicated to public Internet traffic
      • +
    • switch needs to support enough simultaneous VLANs for number of projects
      • +
    • production network configured as 802.1q trunk on switch
      • +
    +
    +
    +

    Operation

    +

    The network node controls the project network configuration:

    +
      +
    • assigns each project a VLAN and private IP range
      • +
    • starts dnsmasq on project VLAN to serve private IP range
      • +
    • configures iptables on network node for default project access
      • +
    • launches CloudPipe instance and configures iptables access
      • +
    +

    When starting an instance the network node:

    +
      +
    • sets up a VLAN interface and bridge on each host as required when an +instance is started on that host
      • +
    • assigns private IP to instance
      • +
    • generates MAC address for instance
      • +
    • update dnsmasq with IP/MAC for instance
      • +
    +

    When starting an instance the compute node:

    +
      +
    • sets up a VLAN interface and bridge on each host as required when an +instance is started on that host
      • +
    +
    +
    +

    Setup

    +
      +
    • Assign VLANs in the switch:
        +
      • public Internet segment
        • +
      • production network
        • +
      • management network
        • +
      • cluster DMZ
        • +
      +
      • +
    • Assign a contiguous range of VLANs to Nova for project use.
      • +
    • Configure management NIC ports as management VLAN access ports.
      • +
    • Configure management VLAN with Internet access as required
      • +
    • Configure production NIC ports as 802.1q trunk ports.
      • +
    • Configure Nova (need to add specifics here)
        +
      • public IPs
        • +
      • instance IPs
        • +
      • project network size
        • +
      • DMZ network
        • +
      +
      • +
    +

    The nova-manage command is used to perform many essential functions for +administration and ongoing maintenance of nova, such as user creation, +vpn management, and much more.

    +

    The standard pattern for executing a nova-manage command is:

    +

    nova-manage <category> <command> [<args>]

    +

    For example, to obtain a list of all projects:

    +

    nova-manage project list

    +

    You can run without arguments to see a list of available command categories:

    +

    nova-manage

    +

    You can run with a category argument to see a list of all commands in that +category:

    +

    nova-manage user

    +
    +

    Installing Nova on a Single Host

    +

    Nova can be run on a single machine, and it is recommended that new users practice managing this type of installation before graduating to multi node systems.

    +

    The fastest way to get a test cloud running is through our Nova Quickstart. But for more detail on installing the system read this doc.

    +
    +

    Step 1 and 2: Get the latest Nova code system software

    +

    Depending on your system, the mehod for accomplishing this varies

    +
    + +
    +
    +
    +

    Step 3: Build and install Nova services

    +

    Switch to the base nova source directory.

    +

    Then type or copy/paste in the following line to compile the Python code for OpenStack Compute.

    +
    sudo python setup.py build
+sudo python setup.py install
    +
    +

    When the installation is complete, you’ll see the following lines:

    +
    Installing nova-network script to /usr/local/bin
+Installing nova-volume script to /usr/local/bin
+Installing nova-objectstore script to /usr/local/bin
+Installing nova-manage script to /usr/local/bin
+Installing nova-scheduler script to /usr/local/bin
+Installing nova-dhcpbridge script to /usr/local/bin
+Installing nova-compute script to /usr/local/bin
+Installing nova-instancemonitor script to /usr/local/bin
+Installing nova-api script to /usr/local/bin
+Installing nova-import-canonical-imagestore script to /usr/local/bin
+
+Installed /usr/local/lib/python2.6/dist-packages/nova-2010.1-py2.6.egg
+Processing dependencies for nova==2010.1
+Finished processing dependencies for nova==2010.1
    +
    +
    +
    +

    Step 4: Create a Nova administrator

    +

    Type or copy/paste in the following line to create a user named “anne.”:

    +
    sudo nova-manage user admin anne
    +
    +

    You see an access key and a secret key export, such as these made-up ones::

    +
    export EC2_ACCESS_KEY=4e6498a2-blah-blah-blah-17d1333t97fd
+export EC2_SECRET_KEY=0a520304-blah-blah-blah-340sp34k05bbe9a7
    +
    +
    +
    +

    Step 5: Create a project with the user you created

    +

    Type or copy/paste in the following line to create a project named IRT (for Ice Road Truckers, of course) with the newly-created user named anne.

    +
    sudo nova-manage project create IRT anne
    +
    +
    Generating RSA private key, 1024 bit long modulus
+.....++++++
+..++++++
+e is 65537 (0x10001)
+Using configuration from ./openssl.cnf
+Check that the request matches the signature
+Signature ok
+The Subject's Distinguished Name is as follows
+countryName           :PRINTABLE:'US'
+stateOrProvinceName   :PRINTABLE:'California'

+
+Write out database with 1 new entries
+Data Base Updated
    +
    +
    +
    +

    Step 6: Unzip the nova.zip

    +

    You should have a nova.zip file in your current working directory. Unzip it with this command:

    +
    unzip nova.zip
    +
    +

    You’ll see these files extract.

    +
    Archive:  nova.zip
+ extracting: novarc
+ extracting: pk.pem
+ extracting: cert.pem
+ extracting: nova-vpn.conf
+ extracting: cacert.pem
    +
    +
    +
    +

    Step 7: Source the rc file

    +

    Type or copy/paste the following to source the novarc file in your current working directory.

    +
    . novarc
    +
    +
    +
    +

    Step 8: Pat yourself on the back :)

    +

    Congratulations, your cloud is up and running, you’ve created an admin user, retrieved the user’s credentials and put them in your environment.

    +

    Now you need an image.

    +
    +
    +

    Step 9: Get an image

    +

    To make things easier, we’ve provided a small image on the Rackspace CDN. Use this command to get it on your server.

    +
    wget http://c2477062.cdn.cloudfiles.rackspacecloud.com/images.tgz
    +
    +
    --2010-10-12 21:40:55--  http://c2477062.cdn.cloudfiles.rackspacecloud.com/images.tgz
+Resolving cblah2.cdn.cloudfiles.rackspacecloud.com... 208.111.196.6, 208.111.196.7
+Connecting to cblah2.cdn.cloudfiles.rackspacecloud.com|208.111.196.6|:80... connected.
+HTTP request sent, awaiting response... 200 OK
+Length: 58520278 (56M) [appication/x-gzip]
+Saving to: `images.tgz'
+
+100%[======================================>] 58,520,278  14.1M/s   in 3.9s
+
+2010-10-12 21:40:59 (14.1 MB/s) - `images.tgz' saved [58520278/58520278]
    +
    +
    +
    +

    Step 10: Decompress the image file

    +

    Use this command to extract the image files::

    +
    tar xvzf images.tgz
    +
    +

    You get a directory listing like so::

    +
    images
+|-- aki-lucid
+|   |-- image
+|   `-- info.json
+|-- ami-tiny
+|   |-- image
+|   `-- info.json
+`-- ari-lucid
+    |-- image
+    `-- info.json
    +
    +
    +
    +

    Step 11: Send commands to upload sample image to the cloud

    +

    Type or copy/paste the following commands to create a manifest for the kernel.:

    +
    euca-bundle-image -i images/aki-lucid/image -p kernel --kernel true
    +
    +

    You should see this in response::

    +

    Checking image
+Tarring image
+Encrypting image
+Splitting image...
+Part: ramdisk.part.0
+Generating manifest /tmp/ramdisk.manifest.xml
    +
    +

    Type or copy/paste the following commands to upload the kernel bundle.:

    Type or copy/paste the following commands to upload the ramdisk bundle.:

    +
    euca-upload-bundle -m /tmp/ramdisk.manifest.xml -b mybucket
    +
    +

    You should see this in response::

    +
    Checking bucket: mybucket
+Uploading manifest file
+Uploading part: ramdisk.part.0
+Uploaded image as mybucket/ramdisk.manifest.xml
    +
    +

    Type or copy/paste the following commands to register the kernel and get its ID.:

    +
    euca-register mybucket/kernel.manifest.xml
    +
    +

    You should see this in response::

    +

    Troubleshooting Installation

    +

    If you see an “error loading the config file ‘./openssl.cnf’” it means you can copy the openssl.cnf file to the location where Nova expects it and reboot, then try the command again.

    +
    cp /etc/ssl/openssl.cnf ~
+sudo reboot
    +

    Cloud Computing 101

    +

    Originally the term cloud came from a diagram that contained a cloud-like shape to contain the +services that afforded computing power that was harnessed to get work done. Much like the electrical +power we receive each day, cloud computing is a model for enabling access to a shared collection of +computing resources - networks for transfer, servers for storage, and applications or services for +completing work.

    +
    +

    Why Cloud?

    +

    Like humans supposedly only use 10% of their brain power, many of the computers in place in data +centers today are underutilized in computing power and networking bandwidth. People also may need a large +amount of computing capacity to complete a computation for example, but don’t need the computing power +once the computation is done. You want cloud computing when you want a service that’s available +on-demand with the flexibility to bring it up or down through automation or with little intervention.

    +
    +
    +

    Attributes of a Cloud

    +

    On-demand self-service - A cloud should enable self-service, so that users can provision servers and networks with little +human intervention.

    +

    Network access - Any computing capabilities are available over the network and you can use many different +devices through standardized mechanisms.

    +

    Resource pooling - Clouds can serve multiple consumers according to demand.

    +

    Elasticity - Provisioning is rapid and scales out or in based on need.

    +

    Metered or measured service - Just like utilities that are paid for by the hour, clouds should optimize +resource use and control it for the level of service or type of servers such as storage or processing.

    +
    +
    +

    Types of Cloud Services

    +

    Cloud computing offers different service models depending on the capabilities a consumer may require. +The US-based National Institute of Standards and Technology offers definitions for cloud computing +and the service models that are emerging.

    +
    +

    SaaS - Software as a Service

    +

    Provides the consumer the ability to use the software in a cloud environment, such as web-based email for example.

    +
    +
    +

    PaaS - Platform as a Service

    +

    Provides the consumer the ability to deploy applications through a programming language or tools supported +by the cloud platform provider. An example of platform as a service is an Eclipse/Java programming +platform provided with no downloads required.

    +
    +
    +

    IaaS - Infrastructure as a Service

    +

    Provides infrastructure such as computer instances, network connections, and storage so that people +can run any software or operating system.

    +
    +

    Todo

    +

    Use definitions from http://csrc.nist.gov/groups/SNS/cloud-computing/ and attribute NIST

    Nova System Architecture

    +

    Nova is built on a shared-nothing, messaging-based architecture. All of the major nova components can be run on multiple servers. This means that most component to component communication must go via message queue. In order to avoid blocking each component while waiting for a response, we use deferred objects, with a callback that gets triggered when a response is received.

    +

    Nova recently moved to using a sql-based central database that is shared by all components in the system. The amount and depth of the data fits into a sql database quite well. For small deployments this seems like an optimal solution. For larger deployments, and especially if security is a concern, nova will be moving towards multiple data stores with some kind of aggregation system.

    +
    +

    Components

    +

    Below you will find a helpful explanation of the different components.

    Nova provides RBAC (Role-based access control) of the AWS-type APIs. We define the following roles:

    +

    Roles-Based Access Control of AWS-style APIs using SAML Assertions +“Achieving FIPS 199 Moderate certification of a hybrid cloud environment using CloudAudit and declarative C.I.A. classifications”

    +
    +
    +

    Introduction

    +

    We will investigate one method for integrating an AWS-style API with US eAuthentication-compatible federated authentication systems, to achieve access controls and limits based on traditional operational roles. +Additionally, we will look at how combining this approach, with an implementation of the CloudAudit APIs, will allow us to achieve a certification under FIPS 199 Moderate classification for a hybrid cloud environment.

    +
    +
    +

    Relationship of US eAuth to RBAC

    +

    Typical implementations of US eAuth authentication systems are structured as follows:

    +
    [ MS Active Directory or other federated LDAP user store ]
+      --> backends to…
+[ SUN Identity Manager or other SAML Policy Controller ]
+      --> maps URLs to groups…
+[ Apache Policy Agent in front of eAuth-secured Web Application ]
    +
    +

    In more ideal implementations, the remainder of the application-specific account information is stored either in extended schema on the LDAP server itself, via the use of a translucent LDAP proxy, or in an independent datastore keyed off of the UID provided via SAML assertion.

    +
    +
    +

    Roles

    +

    AWS API calls are traditionally secured via Access and Secret Keys, which are used to sign API calls, along with traditional timestamps to prevent replay attacks. The APIs can be logically grouped into sets that align with five typical roles:

    +
      +
    • Base User
      • +
    • System Administrator/Developer (currently have the same permissions)
      • +
    • Network Administrator
      • +
    • Project Manager
      • +
    • Cloud Administrator/IT-Security (currently have the same permissions)
      • +
    +

    There is an additional, conceptual end-user that may or may not have API access:

    +
      +
    • (EXTERNAL) End-user / Third-party User
      • +
    +

    Basic operations are available to any :

    +
      +
    • Describe Instances
      • +
    • Describe Images
      • +
    • Describe Volumes
      • +
    • Describe Keypairs
      • +
    • Create Keypair
      • +
    • Delete Keypair
      • +
    • Create, Upload, Delete: Buckets and Keys (Object Store)
      • +
    +

    System Administrators/Developers/Project Manager:

    +
      +
    • Create, Attach, Delete Volume (Block Store)
      • +
    • Launch, Reboot, Terminate Instance
      • +
    • Register/Unregister Machine Image (project-wide)
      • +
    • Request / Review CloudAudit Scans
      • +
    +

    Project Manager:

    +
      +
    • Add and remove other users (currently no api)
      • +
    • Set roles (currently no api)
      • +
    +

    Network Administrator:

    +
      +
    • Change Machine Image properties (public / private)
      • +
    • Change Firewall Rules, define Security Groups
      • +
    • Allocate, Associate, Deassociate Public IP addresses
      • +
    +

    Cloud Administrator/IT-Security:

    +
      +
    • All permissions
      • +
    +
    +
    +

    Enhancements

    +
      +
    • SAML Token passing
      • +
    • REST interfaces
      • +
    • SOAP interfaces
      • +
    +

    Wrapping the SAML token into the API calls. +Then store the UID (fetched via backchannel) into the instance metadata, providing end-to-end auditability of ownership and responsibility, without PII.

    +
    +
    +

    CloudAudit APIs

    +
      +
    • Request formats
      • +
    • Response formats
      • +
    • Stateless asynchronous queries
      • +
    +

    CloudAudit queries may spawn long-running processes (similar to launching instances, etc.) They need to return a ReservationId in the same fashion, which can be returned in further queries for updates. +RBAC of CloudAudit API calls is critical, since detailed system information is a system vulnerability.

    +
    +
    +

    Type declarations

    +
      +
    • Data declarations – Volumes and Objects
      • +
    • System declarations – Instances
      • +
    +

    Existing API calls to launch instances specific a single, combined “type” flag. We propose to extend this with three additional type declarations, mapping to the “Confidentiality, Integrity, Availability” classifications of FIPS 199. An example API call would look like:

    +
    RunInstances type=m1.large number=1 secgroup=default key=mykey confidentiality=low integrity=low availability=low
    +
    +

    These additional parameters would also apply to creation of block storage volumes (along with the existing parameter of ‘size’), and creation of object storage ‘buckets’. (C.I.A. classifications on a bucket would be inherited by the keys within this bucket.)

    +
    +
    +

    Request Brokering

    +
      +
    • Cloud Interop
      • +
    • IMF Registration / PubSub
      • +
    • Digital C&A
      • +
    +

    Establishing declarative semantics for individual API calls will allow the cloud environment to seamlessly proxy these API calls to external, third-party vendors – when the requested CIA levels match.

    +

    See related work within the Infrastructure 2.0 working group for more information on how the IMF Metadata specification could be utilized to manage registration of these vendors and their C&A credentials.

    +
    +
    +

    Dirty Cloud – Hybrid Data Centers

    +
      +
    • CloudAudit bridge interfaces
      • +
    • Anything in the ARP table
      • +
    +

    A hybrid cloud environment provides dedicated, potentially co-located physical hardware with a network interconnect to the project or users’ cloud virtual network.

    +

    This interconnect is typically a bridged VPN connection. Any machines that can be bridged into a hybrid environment in this fashion (at Layer 2) must implement a minimum version of the CloudAudit spec, such that they can be queried to provide a complete picture of the IT-sec runtime environment.

    +

    Network discovery protocols (ARP, CDP) can be applied in this case, and existing protocols (SNMP location data, DNS LOC records) overloaded to provide CloudAudit information.

    +
    +
    +

    The Details

    +
      +
    • Preliminary Roles Definitions
      • +
    • Categorization of available API calls
      • +
    • SAML assertion vocabulary
      • +
    +
    +
    +

    System limits

    +

    The following limits need to be defined and enforced:

    +
      +
    • Total number of instances allowed (user / project)
      • +
    • Total number of instances, per instance type (user / project)
      • +
    • Total number of volumes (user / project)
      • +
    • Maximum size of volume
      • +
    • Cumulative size of all volumes
      • +
    • Total use of object storage (GB)
      • +
    • Total number of Public IPs
      • +
    +
    +
    +

    Further Challenges

    +
      +
    • Prioritization of users / jobs in shared computing environments
      • +
    • Incident response planning
      • +
    • Limit launch of instances to specific security groups based on AMI
      • +
    • Store AMIs in LDAP for added property control

    Cloudpipe – Per Project Vpns

    +

    Cloudpipe is a method for connecting end users to their project insnances in vlan mode.

    +
    +

    Overview

    +

    The support code for cloudpipe implements admin commands (via nova-manage) to automatically create a vm for a project that allows users to vpn into the private network of their project. Access to this vpn is provided through a public port on the network host for the project. This allows users to have free access to the virtual machines in their project without exposing those machines to the public internet.

    +
    +
    +

    Cloudpipe Image

    +

    The cloudpipe image is basically just a linux instance with openvpn installed. It needs a simple script to grab user data from the metadata server, b64 decode it into a zip file, and run the autorun.sh script from inside the zip. The autorun script will configure and run openvpn to run using the data from nova.

    +

    It is also useful to have a cron script that will periodically redownload the metadata and copy the new crl. This will keep revoked users from connecting and will disconnect any users that are connected with revoked certificates when their connection is renegotiated (every hour).

    +
    +
    +

    Cloudpipe Launch

    +

    When you use nova-manage to launch a cloudpipe for a user, it goes through the following process:

    +
      +
    1. creates a keypair called <project_id>-vpn and saves it in the keys directory
      2. +
    2. creates a security group <project_id>-vpn and opens up 1194 and icmp
      3. +
    3. creates a cert and private key for the vpn instance and saves it in the CA/projects/<project_id>/ directory
      4. +
    4. zips up the info and puts it b64 encoded as user data
      5. +
    5. launches an m1.tiny instance with the above settings using the flag-specified vpn image
      6. +
    +
    +
    +

    Vpn Access

    +

    In vlan networking mode, the second ip in each private network is reserved for the cloudpipe instance. This gives a consistent ip to the instance so that nova-network can create forwarding rules for access from the outside world. The network for each project is given a specific high-numbered port on the public ip of the network host. This port is automatically forwarded to 1194 on the vpn instance.

    +

    If specific high numbered ports do not work for your users, you can always allocate and associate a public ip to the instance, and then change the vpn_public_ip and vpn_public_port in the database. This will be turned into a nova-manage command or a flag soon.

    +
    +
    +

    Certificates and Revocation

    +

    If the use_project_ca flag is set (required to for cloudpipes to work securely), then each project has its own ca. This ca is used to sign the certificate for the vpn, and is also passed to the user for bundling images. When a certificate is revoked using nova-manage, a new Certificate Revocation List (crl) is generated. As long as cloudpipe has an updated crl, it will block revoked users from connecting to the vpn.

    The nova networking components manage private networks, public IP addressing, VPN connectivity, and firewall rules.

    +
    +
    +

    Components

    +

    There are several key components:

    +
      +
    • NetworkController (Manages address and vlan allocation)
      • +
    • RoutingNode (NATs public IPs to private IPs, and enforces firewall rules)
      • +
    • AddressingNode (runs DHCP services for private networks)
      • +
    • BridgingNode (a subclass of the basic nova ComputeNode)
      • +
    • TunnelingNode (provides VPN connectivity)
      • +
    +
    +
    +

    Component Diagram

    +

    Overview:

    +
                                   (PUBLIC INTERNET)
+                                |              \
+                               / \             / \
+                 [RoutingNode] ... [RN]    [TunnelingNode] ... [TN]
+                       |             \    /       |              |

+                      / \             / \         / \         / \
+                       [BridgingNode] ...          [BridgingNode]
+
+
+                 [NetworkController]   ...    [NetworkController]
+                                   \          /
+                                     < AMQP >
+                                        |
+                                       / \
+                      [CloudController]...[CloudController]
    +
    +

    While this diagram may not make this entirely clear, nodes and controllers communicate exclusively across the message bus (AMQP, currently).

    +
    +
    +

    State Model

    +

    Network State consists of the following facts:

    +
      +
    • VLAN assignment (to a project)
      • +
    • Private Subnet assignment (to a security group) in a VLAN
      • +
    • Private IP assignments (to running instances)
      • +
    • Public IP allocations (to a project)
      • +
    • Public IP associations (to a private IP / running instance)
      • +
    +

    While copies of this state exist in many places (expressed in IPTables rule chains, DHCP hosts files, etc), the controllers rely only on the distributed “fact engine” for state, queried over RPC (currently AMQP). The NetworkController inserts most records into this datastore (allocating addresses, etc) - however, individual nodes update state e.g. when running instances crash.

    +
    +
    +

    The Public Traffic Path

    +

    Public Traffic:

    +
                   (PUBLIC INTERNET)
+                      |
+                    <NAT>  <-- [RoutingNode]
+                      |
+[AddressingNode] -->  |
+                   ( VLAN )
+                      |    <-- [BridgingNode]
+                      |
+               <RUNNING INSTANCE>
    +
    +

    The RoutingNode is currently implemented using IPTables rules, which implement both NATing of public IP addresses, and the appropriate firewall chains. We are also looking at using Netomata / Clusto to manage NATting within a switch or router, and/or to manage firewall rules within a hardware firewall appliance.

    +

    Similarly, the AddressingNode currently manages running DNSMasq instances for DHCP services. However, we could run an internal DHCP server (using Scapy ala Clusto), or even switch to static addressing by inserting the private address into the disk image the same way we insert the SSH keys. (See compute for more details).

    Services, Managers and Drivers

    +

    The responsibilities of Services, Managers, and Drivers, can be a bit confusing to people that are new to nova. This document attempts to outline the division of responsibilities to make understanding the system a little bit easier.

    +

    Currently, Managers and Drivers are specified by flags and loaded using utils.load_object(). This method allows for them to be implemented as singletons, classes, modules or objects. As long as the path specified by the flag leads to an object (or a callable that returns an object) that responds to getattr, it should work as a manager or driver.

    +
    +
    +

    The nova.manager Module

    +
    +
    +

    Implementation-Specific Drivers

    +

    A manager will generally load a driver for some of its tasks. The driver is responsible for specific implementation details. Anything running shell commands on a host, or dealing with other non-python code should probably be happening in a driver.

    +

    Drivers should minimize touching the database, although it is currently acceptable for implementation specific data. This may be reconsidered at some point.

    +

    It usually makes sense to define an Abstract Base Class for the specific driver (i.e. VolumeDriver), to define the methods that a different driver would need to implement.

    Old Docs

    +

    Nova uses ata-over-ethernet (AoE) to export storage volumes from multiple storage nodes. These AoE exports are attached (using libvirt) directly to running instances.

    +

    Nova volumes are exported over the primary system VLAN (usually VLAN 1), and not over individual VLANs.

    +

    AoE exports are numbered according to a “shelf and blade” syntax. In order to avoid collisions, we currently perform an AoE-discover of existing exports, and then grab the next unused number. (This obviously has race condition problems, and should be replaced by allocating a shelf-id to each storage node.)

    +

    The underlying volumes are LVM logical volumes, created on demand within a single large volume group.

    Welcome to Nova’s documentation!

    +

    Nova is a cloud computing fabric controller, the main part of an IaaS system. +Individuals and organizations can use Nova to host and manage their own cloud +computing systems. Nova originated as a project out of NASA Ames Research Laboratory.

    +

    Nova is written with the following design guidelines in mind:

    +
      +
    • Component based architecture: Quickly add new behaviors
      • +
    • Highly available: Scale to very serious workloads
      • +
    • Fault-Tollerant: Isloated processes avoid cascading failures
      • +
    • Recoverable: Failures should be easy to diagnose, debug, and rectify
      • +
    • Open Standards: Be a reference implementation for a community-driven api
      • +
    • API Compatibility: Nova strives to provide API-compatible with popular systems like Amazon EC2
      • +
    +

    This documentation is generated by the Sphinx toolkit and lives in the source +tree. Additional documentation on Nova and other components of OpenStack can +be found on the OpenStack wiki. Also see the Getting Involved page for +other ways to interact with the community.

    Nova Concepts and Introduction

    +
    +

    Introduction

    +

    Nova is the software that controls your Infrastructure as as Service (IaaS) +cloud computing platform. It is similar in scope to Amazon EC2 and Rackspace +CloudServers. Nova does not include any virtualization software, rather it +defines drivers that interact with underlying virtualization mechanisms that +run on your host operating system, and exposes functionality over a web API.

    +

    This document does not attempt to explain fundamental concepts of cloud +computing, IaaS, virtualization, or other related technologies. Instead, it +focuses on describing how Nova’s implementation of those concepts is achieved.

    +

    This page outlines concepts that you will need to understand as a user or +administrator of an OpenStack installation. Each section links to more more +detailed information in the Administration Guide, +but you’ll probably want to read this section straight-through before tackling +the specifics presented in the administration guide.

    +
    +
    +

    Concept: Users and Projects

    +
      +
    • access to images is limited by project
      • +
    • access/secret are per user
      • +
    • keypairs are per user
      • +
    • quotas are per project
      • +
    +
    +
    +

    Concept: Virtualization

    +
      +
    • KVM
      • +
    • UML
      • +
    • XEN
      • +
    • HyperV
      • +
    • qemu
      • +
    +
    +
    +

    Concept: Instances

    +

    An ‘instance’ is a word for a virtual machine that runs inside the cloud.

    +
    +
    +

    Concept: Storage

    +
    +

    Volumes

    +

    A ‘volume’ is a detachable block storage device. You can think of it as a usb hard drive. It can only be attached to one instance at a time, so it does not work like a SAN. If you wish to expose the same volume to multiple instances, you will have to use an NFS or SAMBA share from an existing instance.

    +
    +
    +

    Local Storage

    +

    Every instance larger than m1.tiny starts with some local storage (up to 160GB for m1.xlarge). This storage is currently the second partition on the root drive.

    +
    +
    +
    +

    Concept: Quotas

    +

    Nova supports per-project quotas. There are currently quotas for number of instances, total number of cores, number of volumes, total number of gigabytes, and number of floating ips.

    +
    +
    +

    Concept: RBAC

    +

    Nova provides roles based access control (RBAC) for access to api commands. A user can have a number of different roles. Roles define which api_commands a user can perform.

    +

    It is important to know that there are user-specific (sometimes called global) roles and project-specific roles. A user’s actual permissions in a particular project are the INTERSECTION of his user-specific roles and is project-specific roles.

    +

    For example: A user can access api commands allowed to the netadmin role (like allocate_address) only if he has the user-specific netadmin role AND the project-specific netadmin role.

    +

    More information about RBAC can be found in the Authentication and Authorization.

    +
    +
    +

    Concept: API

    +
      +
    • EC2
      • +
    • OpenStack / Rackspace
      • +
    +
    +
    +

    Concept: Networking

    +

    Nova has a concept of Fixed Ips and Floating ips. Fixed ips are assigned to an instance on creation and stay the same until the instance is explicitly terminated. Floating ips are ip addresses that can be dynamically associated with an instance. This address can be disassociated and associated with another instance at any time.

    +

    There are multiple strategies available for implementing fixed ips:

    +
    +

    Flat Mode

    +

    The simplest networking mode. Each instance receives a fixed ip from the pool. All instances are attached to the same bridge (br100) by default. The bridge must be configured manually. The networking configuration is injected into the instance before it is booted. Note that this currently only works on linux-style systems that keep networking configuration in /etc/network/interfaces.

    +
    +
    +

    Flat DHCP Mode

    +

    This is similar to the flat mode, in that all instances are attached to the same bridge. In this mode nova does a bit more configuration, it will attempt to bridge into an ethernet device (eth0 by default). It will also run dnsmasq as a dhcpserver listening on this bridge. Instances receive their fixed ips by doing a dhcpdiscover.

    +
    +
    +

    VLAN DHCP Mode

    +

    This is the default networking mode and supports the most features. For multiple machine installation, it requires a switch that supports host-managed vlan tagging. In this mode, nova will create a vlan and bridge for each project. The project gets a range of private ips that are only accessible from inside the vlan. In order for a user to access the instances in their project, a special vpn instance (code named cloudpipe) needs to be created. Nova generates a certificate and key for the user to access the vpn and starts the vpn automatically. More information on cloudpipe can be found here.

    +

    The following diagram illustrates how the communication that occurs between the vlan (the dashed box) and the public internet (represented by the two clouds)

    +_images/cloudpipe.png +
    +
    +
    +

    Concept: Binaries

    +

    Nova is implemented by a number of related binaries. These binaries can run on the same machine or many machines. A detailed description of each binary is given in the binaries section of the developer guide.

    +
    +
    +

    Concept: nova-manage

    +

    The nova-manage command is used to perform many essential functions for +administration and ongoing maintenance of nova, such as user creation, +vpn management, and much more.

    +

    See doc:nova.manage in the Administration Guide for more details.

    +
    +
    +

    Concept: Flags

    +

    python-gflags

    +
    +
    +

    Concept: Plugins

    +
      +
    • Managers/Drivers: utils.import_object from string flag
      • +
    • virt/connections: conditional loading from string flag
      • +
    • db: LazyPluggable via string flag
      • +
    • auth_manager: utils.import_class based on string flag
      • +
    • Volumes: moving to pluggable driver instead of manager
      • +
    • Network: pluggable managers
      • +
    • Compute: same driver used, but pluggable at connection
      • +
    +
    +
    +

    Concept: IPC/RPC

    +

    Nova utilizes the RabbitMQ implementation of the AMQP messaging standard for performing communication between the various nova services. This message queuing service is used for both local and remote communication because Nova is designed so that there is no requirement that any of the services exist on the same physical machine. RabbitMQ in particular is very robust and provides the efficiency and reliability that Nova needs. More information about RabbitMQ can be found at http://www.rabbitmq.com/.

    +
    +

    +
      +
    • auth
      • +
    • ldap
      • +

    Concept: Certificate Authority

    +

    Nova does a small amount of certificate management. These certificates are used for project vpns and decrypting bundled images.

    The contrib/nova.sh file in the source distribution is a script that +will quickly set up nova to run on a single machine. It is tested against +Ubuntu only, but other distributions are forthcoming.

    +
    +
    +

    Environment Variables

    +

    By tweaking the environment that nova.sh run in, you can build slightly +different configurations (though for more complex setups you should see +Getting Started with Nova and Installing Nova on Multiple Servers).

    +
      +
    • +
      HOST_IP
      +
        +
      • Default: address of first interface from the ifconfig command
        • +
      • Values: 127.0.0.1, or any other valid address
        • +
      +
      +
      +
      • +
    +
    +

    TEST

    +

    Default: 0 +Values: 1, run tests after checkout and initial setup

    +
    +
    +

    USE_MYSQL

    +

    Default: 0, use sqlite3 +Values: 1, use mysql instead of sqlite3

    +
    +
    +

    MYSQL_PASS

    +

    Only useful if $USE_MYSQL=1.

    +

    Default: nova +Values: value of root password for mysql

    +
    +
    +

    USE_LDAP

    +

    Default: 0, use nova.auth.dbdriver +Values: 1, use nova.auth.ldapdriver

    +
    +
    +

    LIBVIRT_TYPE

    +

    Default: qemu +Values: uml, kvm

    +
    +
    +
    +

    Usage

    +

    Unless you want to spend a lot of time fiddling with permissions and sudoers, +you should probably run nova as root.

    +
    sudo -i
+
    +
    +

    If you are concerned about security, nova runs just fine inside a virtual +machine.

    +

    Use the script to install and run the current trunk. You can also specify a +specific branch by putting lp:~someone/nova/some-branch after the branch +command

    +
    ./nova.sh branch
+./nova.sh install
+./nova.sh run
    +
    +

    The run command will drop you into a screen session with all of the workers +running in different windows You can use eucatools to run commands against the +cloud.

    +
    euca-add-keypair test > test.pem
+euca-run-instances -k test -t m1.tiny ami-tiny
+euca-describe-instances
    +
    +

    To see output from the various workers, switch screen windows

    +
    <ctrl-a> "
    +
    +

    will give you a list of running windows.

    +

    When the instance is running, you should be able to ssh to it.

    +
    chmod 600 test.pem
+ssh -i test.pem root@10.0.0.3
    +
    +

    When you exit screen

    +
    <ctrl-a> <ctrl-d>
    +
    +

    nova will terminate. It may take a while for nova to finish cleaning up. If +you exit the process before it is done because there were some problems in your +build, you may have to clean up the nova processes manually. If you had any +instances running, you can attempt to kill them through the api:

    +
    ./nova.sh terminate
    +
    +

    Then you can destroy the screen:

    +
    ./nova.sh clean
    +
    +

    If things get particularly messed up, you might need to do some more intense +cleanup. Be careful, the following command will manually destroy all runnning +virsh instances and attempt to delete all vlans and bridges.

    +
    ./nova.sh scrub
    +
    +

    You can edit files in the install directory or do a bzr pull to pick up new versions. You only need to do

    +
    ./nova.sh run
    +
    +

    to run nova after the first install. The database should be cleaned up on each run.

    Service Architecture

    +

    Nova’s Cloud Fabric is composed of the following major components:

    +
      +
    • API Server
      • +
    • Message Queue
      • +
    • Compute Worker
      • +
    • Network Controller
      • +
    • Volume Worker
      • +
    • Scheduler
      • +
    • Image Store
      • +

    +

    API Server

    +

    At the heart of the cloud framework is an API Server. This API Server makes command and control of the hypervisor, storage, and networking programmatically available to users in realization of the definition of cloud computing.

    +

    The API endpoints are basic http web services which handle authentication, authorization, and basic command and control functions using various API interfaces under the Amazon, Rackspace, and related models. This enables API compatibility with multiple existing tool sets created for interaction with offerings from other vendors. This broad compatibility prevents vendor lock-in.

    +
    +
    +

    Message Queue

    +

    A messaging queue brokers the interaction between compute nodes (processing), volumes (block storage), the networking controllers (software which controls network infrastructure), API endpoints, the scheduler (determines which physical hardware to allocate to a virtual resource), and similar components. Communication to and from the cloud controller is by HTTP requests through multiple API endpoints.

    +

    A typical message passing event begins with the API server receiving a request from a user. The API server authenticates the user and ensures that the user is permitted to issue the subject command. Availability of objects implicated in the request is evaluated and, if available, the request is routed to the queuing engine for the relevant workers. Workers continually listen to the queue based on their role, and occasionally their type hostname. When such listening produces a work request, the worker takes assignment of the task and begins its execution. Upon completion, a response is dispatched to the queue which is received by the API server and relayed to the originating user. Database entries are queried, added, or removed as necessary throughout the process.

    +
    +
    +

    Compute Worker

    +

    Compute workers manage computing instances on host machines. Through the API, commands are dispatched to compute workers to:

    +
      +
    • Run instances
      • +
    • Terminate instances
      • +
    • Reboot instances
      • +
    • Attach volumes
      • +
    • Detach volumes
      • +
    • Get console output
      • +
    +
    +
    +

    Network Controller

    +

    The Network Controller manages the networking resources on host machines. The API server dispatches commands through the message queue, which are subsequently processed by Network Controllers. Specific operations include:

    +
      +
    • Allocate Fixed IP Addresses
      • +
    • Configuring VLANs for projects
      • +
    • Configuring networks for compute nodes
      • +
    +
    +
    +

    Volume Workers

    +

    Volume Workers interact with iSCSI storage to manage LVM-based instance volumes. Specific functions include:

    +
      +
    • Create Volumes
      • +
    • Delete Volumes
      • +
    • Establish Compute volumes
      • +
    +

    Volumes may easily be transferred between instances, but may be attached to only a single instance at a time.

    +
    +

      The nova.virt.fake Driver

      +

      A fake (in-memory) hypervisor+api.

      +

      Allows nova testing w/o a hypervisor. This module also documents the +semantics of real hypervisor connections.

      +
      +
      +class nova.virt.fake.FakeConnection
      +

      Bases: object

      +

      The interface to this class talks in terms of ‘instances’ (Amazon EC2 and +internal Nova terminology), by which we mean ‘running virtual machine’ +(XenAPI terminology) or domain (Xen or libvirt terminology).

      +

      An instance has an ID, which is the identifier chosen by Nova to represent +the instance further up the stack. This is unfortunately also called a +‘name’ elsewhere. As far as this layer is concerned, ‘instance ID’ and +‘instance name’ are synonyms.

      +

      Note that the instance ID or name is not human-readable or +customer-controlled – it’s an internal ID chosen by Nova. At the +nova.virt layer, instances do not have human-readable names at all – such +things are only known higher up the stack.

      +

      Most virtualization platforms will also have their own identity schemes, +to uniquely identify a VM or domain. These IDs must stay internal to the +platform-specific layer, and never escape the connection interface. The +platform-specific layer is responsible for keeping track of which instance +ID maps to which platform-specific ID, and vice versa.

      +

      In contrast, the list_disks and list_interfaces calls may return +platform-specific IDs. These identify a specific virtual disk or specific +virtual network interface, and these IDs are opaque to the rest of Nova.

      +

      Some methods here take an instance of nova.compute.service.Instance. This +is the datastructure used by nova.compute to store details regarding an +instance, and pass them into this layer. This layer is responsible for +translating that generic datastructure into terms that are specific to the +virtualization platform.

      +
      +
      +FakeConnection.attach_volume(instance_name, device_path, mountpoint)
      +

      Attach the disk at device_path to the instance at mountpoint

      +
      + +
      +
      +FakeConnection.block_stats(instance_name, disk_id)
      +

      Return performance counters associated with the given disk_id on the +given instance_name. These are returned as [rd_req, rd_bytes, wr_req, +wr_bytes, errs], where rd indicates read, wr indicates write, req is +the total number of I/O requests made, bytes is the total number of +bytes transferred, and errs is the number of requests held up due to a +full pipeline.

      +

      All counters are long integers.

      +

      This method is optional. On some platforms (e.g. XenAPI) performance +statistics can be retrieved directly in aggregate form, without Nova +having to do the aggregation. On those platforms, this method is +unused.

      +

      Note that this function takes an instance ID, not a +compute.service.Instance, so that it can be called by compute.monitor.

      +
      + +
      +
      +FakeConnection.destroy(instance)
      +

      Destroy (shutdown and delete) the specified instance.

      +

      The given parameter is an instance of nova.compute.service.Instance, +and so the instance is being specified as instance.name.

      +

      The work will be done asynchronously. This function returns a +Deferred that allows the caller to detect when it is complete.

      +
      + +
      +
      +FakeConnection.detach_volume(instance_name, mountpoint)
      +

      Detach the disk attached to the instance at mountpoint

      +
      + +

      +FakeConnection.get_info(instance_name)
      +

      Get a block of information about the given instance. This is returned +as a dictionary containing ‘state’: The power_state of the instance, +‘max_mem’: The maximum memory for the instance, in KiB, ‘mem’: The +current memory the instance has, in KiB, ‘num_cpu’: The current number +of virtual CPUs the instance has, ‘cpu_time’: The total CPU time used +by the instance, in nanoseconds.

      +

      This method should raise exception.NotFound if the hypervisor has no +knowledge of the instance

      +
      + +
      +
      +FakeConnection.interface_stats(instance_name, iface_id)
      +

      Return performance counters associated with the given iface_id on the +given instance_id. These are returned as [rx_bytes, rx_packets, +rx_errs, rx_drop, tx_bytes, tx_packets, tx_errs, tx_drop], where rx +indicates receive, tx indicates transmit, bytes and packets indicate +the total number of bytes or packets transferred, and errs and dropped +is the total number of packets failed / dropped.

      +

      All counters are long integers.

      +
      +FakeConnection.list_disks(instance_name)
      +

      Return the IDs of all the virtual disks attached to the specified +instance, as a list. These IDs are opaque to the caller (they are +only useful for giving back to this layer as a parameter to +disk_stats). These IDs only need to be unique for a given instance.

      +
      + +

      +

      Return the names of all the instances known to the virtualization +layer, as a list.

      +
      + +
      +
      +FakeConnection.list_interfaces(instance_name)
      +

      Return the IDs of all the virtual network interfaces attached to the +specified instance, as a list. These IDs are opaque to the caller +(they are only useful for giving back to this layer as a parameter to +interface_stats). These IDs only need to be unique for a given +instance.

      +

      Reboot the specified instance.

      +

      The given parameter is an instance of nova.compute.service.Instance, +and so the instance is being specified as instance.name.

      +

      The work will be done asynchronously. This function returns a +Deferred that allows the caller to detect when it is complete.

      +

      Rescue the specified instance.

      + +
      +
      +FakeConnection.spawn(instance)
      +

      Create a new instance/VM/domain on the virtualization platform.

      +

      The given parameter is an instance of nova.compute.service.Instance. +This function should use the data there to guide the creation of +the new instance.

      +

      The work will be done asynchronously. This function returns a +Deferred that allows the caller to detect when it is complete.

      +

      Once this successfully completes, the instance should be +running (power_state.RUNNING).

      +

      If this fails, any partial instance should be completely +cleaned up, and the virtualization platform should be in the state +that it was before this call began.

      +
      + +
      +
      +FakeConnection.unrescue(instance)

      Unrescue the specified instance.

These are returned as [rd_req, rd_bytes, wr_req, +wr_bytes, errs], where rd indicates read, wr indicates write, req is +the total number of I/O requests made, bytes is the total number of +bytes transferred, and errs is the number of requests held up due to a +full pipeline.

        +

        All counters are long integers.

        +

        This method is optional. On some platforms (e.g. XenAPI) performance +statistics can be retrieved directly in aggregate form, without Nova +having to do the aggregation. On those platforms, this method is +unused.

        +

        Reboot the specified instance.

        +

        The given parameter is an instance of nova.compute.service.Instance, +and so the instance is being specified as instance.name.

        +

        The work will be done asynchronously. This function returns a +Deferred that allows the caller to detect when it is complete.

        +
        + +
        +
        +FakeConnection.spawn(instance)
        +

        Create a new instance/VM/domain on the virtualization platform.

        +

        The given parameter is an instance of nova.compute.service.Instance. +This function should use the data there to guide the creation of +the new instance.

        +

        The work will be done asynchronously. This function returns a +Deferred that allows the caller to detect when it is complete.

        +

        Once this successfully completes, the instance should be +running (power_state.RUNNING).

A DHCP Server is started for each VLAN to pass out IP addresses to VM instances from the subnet assigned to the project.

    The network assignment to a project, and IP address assignment to a VM instance, are triggered when a user starts to run a VM instance. When running a VM instance, a user needs to specify a project for the instances, and the security groups (described in Security Groups) when the instance wants to join. If this is the first instance to be created for the project, then Nova (the cloud controller) needs to find a network controller to be the network host for the project; it then sets up a private network by finding an unused VLAN id, an unused subnet, and then the controller assigns them to the project, it also assigns a name to the project’s Linux bridge, and allocating a private IP within the project’s subnet for the new instance.

    If the instance the user wants to start is not the project’s first, a subnet and a VLAN must have already been assigned to the project; therefore the system needs only to find an available IP address within the subnet and assign it to the new starting instance. If there is no private IP available within the subnet, an exception will be raised to the cloud controller, and the VM creation cannot proceed.

Nova therefore supports injecting ssh keys into instances before they are booted. This allows a user to login to the instances that he or she creates securely.

A Nova project consists of a number of VM instances created by a user. For each VM instance, Nova assigns to it a private IP address. (Currently, Nova only supports Linux bridge networking that allows the virtual interfaces to connect to the outside network through the physical interface. Other virtual network technologies, such as Open vSwitch, could be supported in the future.) The Network Controller provides virtual networks to enable compute servers to interact with each other and with the public network. - -.. - (perhaps some of this should be moved elsewhere) - Introduction - ------------ - - Nova consists of seven main components, with the Cloud Controller component representing the global state and interacting with all other components. API Server acts as the Web services front end for the cloud controller. Compute Controller provides compute server resources, and the Object Store component provides storage services. Auth Manager provides authentication and authorization services. Volume Controller provides fast and permanent block-level storage for the comput servers. Network Controller provides virtual networks to enable compute servers to interact with each other and with the public network. Scheduler selects the most suitable compute controller to host an instance. - - .. todo:: Insert Figure 1 image from "An OpenStack Network Overview" contributed by Citrix - - Nova is built on a shared-nothing, messaging-based architecture. All of the major components, that is Compute Controller, Volume Controller, Network Controller, and Object Store can be run on multiple servers. Cloud Controller communicates with Object Store via HTTP (Hyper Text Transfer Protocol), but it communicates with Scheduler, Network Controller, and Volume Controller via AMQP (Advanced Message Queue Protocol). To avoid blocking each component while waiting for a response, Nova uses asynchronous calls, with a call-back that gets triggered when a response is received. - - To achieve the shared-nothing property with multiple copies of the same component, Nova keeps all the cloud system state in a distributed data store. Updates to system state are written into this store, using atomic transactions when required. Requests for system state are read out of this store. In limited cases, the read results are cached within controllers for short periods of time (for example, the current list of system users.) - - .. note:: The database schema is available on the `OpenStack Wiki _`. - -Nova Network Strategies ------------------------ - -Currently, Nova supports three kinds of networks, implemented in three "Network Manager" types respectively: Flat Network Manager, Flat DHCP Network Manager, and VLAN Network Manager. The three kinds of networks can c-exist in a cloud system. However, the scheduler for selecting the type of network for a given project is not yet implemented. Here is a brief description of each of the different network strategies, with a focus on the VLAN Manager in a separate section. - -Read more about Nova network strategies here: - -.. toctree:: - :maxdepth: 1 - - network.flat.rst - network.vlan.rst - - -Network Management Commands ---------------------------- - -Admins and Network Administrators can use the 'nova-manage' command to manage network resources: - -VPN Management -~~~~~~~~~~~~~~ - -* vpn list: Print a listing of the VPNs for all projects. - * arguments: none -* vpn run: Start the VPN for a given project. - * arguments: project -* vpn spawn: Run all VPNs. - * arguments: none - - -Floating IP Management -~~~~~~~~~~~~~~~~~~~~~~ - -* floating create: Creates floating ips for host by range - * arguments: host ip_range -* floating delete: Deletes floating ips by range - * arguments: range -* floating list: Prints a listing of all floating ips - * arguments: none - -Network Management -~~~~~~~~~~~~~~~~~~ - -* network create: Creates fixed ips for host by range - * arguments: [fixed_range=FLAG], [num_networks=FLAG], - [network_size=FLAG], [vlan_start=FLAG], - [vpn_start=FLAG] - diff --git a/doc/build/html/_sources/adminguide/managing.projects.txt b/doc/build/html/_sources/adminguide/managing.projects.txt deleted file mode 100644 index b592e14d7..000000000 --- a/doc/build/html/_sources/adminguide/managing.projects.txt +++ /dev/null @@ -1,68 +0,0 @@ -.. - Copyright 2010 United States Government as represented by the - Administrator of the National Aeronautics and Space Administration. - All Rights Reserved. - - Licensed under the Apache License, Version 2.0 (the "License"); you may - not use this file except in compliance with the License.

A user can specify which project he or she wishes to use by appending `:project_id` to his or her access key.

The user's access key needs to be included in the request, and the request must be signed with the secret key. Upon receipt of api requests, nova will verify the signature and execute commands on behalf of the user. - -In order to begin using nova, you will need a to create a user. This can be easily accomplished using the user create or user admin commands in nova-manage. `user create` will create a regular user, whereas `user admin` will create an admin user. The syntax of the command is nova-manage user create username [access] [secret]. For example:: - - nova-manage user create john my-access-key a-super-secret-key - -If you do not specify an access or secret key, a random uuid will be created automatically. - -Credentials ------------ - -Nova can generate a handy set of credentials for a user. These credentials include a CA for bundling images and a file for setting environment variables to be used by euca2ools. If you don't need to bundle images, just the environment script is required. You can export one with the `project environment` command. The syntax of the command is nova-manage project environment project_id user_id [filename]. If you don't specify a filename, it will be exported as novarc. After generating the file, you can simply source it in bash to add the variables to your environment:: - - nova-manage project environment john_project john - . novarc - -If you do need to bundle images, you will need to get all of the credentials using `project zipfile`.

Example usage:: - - nova-manage project zipfile john_project john - unzip nova.zip - . novarc - -Role Based Access Control -------------------------- -Roles control the api actions that a user is allowed to perform. For example, a user cannot allocate a public ip without the `netadmin` role. It is important to remember that a users de facto permissions in a project is the intersection of user (global) roles and project (local) roles. So for john to have netadmin permissions in his project, he needs to separate roles specified. You can add roles with `role add`. The syntax is nova-manage role add user_id role [project_id]. Let's give john the netadmin role for his project:: - - nova-manage role add john netadmin - nova-manage role add john netadmin john_project - -Role-based access control (RBAC) is an approach to restricting system access to authorized users based on an individual’s role within an organization. Various employee functions require certain levels of system access in order to be successful. These functions are mapped to defined roles and individuals are categorized accordingly. Since users are not assigned permissions directly, but only acquire them through their role (or roles), management of individual user rights becomes a matter of assigning appropriate roles to the user. This simplifies common operations, such as adding a user, or changing a user's department. - -Nova’s rights management system employs the RBAC model and currently supports the following five roles: - -* **Cloud Administrator.** (admin) Users of this class enjoy complete system access. -* **IT Security.** (itsec) This role is limited to IT security personnel. It permits role holders to quarantine instances. -* **Project Manager.** (projectmanager)The default for project owners, this role affords users the ability to add other users to a project, interact with project images, and launch and terminate instances. -* **Network Administrator.** (netadmin) Users with this role are permitted to allocate and assign publicly accessible IP addresses as well as create and modify firewall rules. -* **Developer.** This is a general purpose role that is assigned to users by default. - -RBAC management is exposed through the dashboard for simplified user management. - - -User Commands -~~~~~~~~~~~~ - -Users, including admins, are created through the ``user`` commands. - -* user admin: creates a new admin and prints exports - * arguments: name [access] [secret] -* user create: creates a new user and prints exports - * arguments: name [access] [secret] -* user delete: deletes an existing user - * arguments: name -* user exports: prints access and secrets for user in export format - * arguments: name -* user list: lists all users - * arguments: none -* user modify: update a users keys & admin flag - * arguments: accesskey secretkey admin - * leave any field blank to ignore it, admin should be 'T', 'F', or blank - - -User Role Management -~~~~~~~~~~~~~~~~~~~~ - -* role add: adds role to user - * if project is specified, adds project specific role - * arguments: user, role [project] -* role has: checks to see if user has role - * if project is specified, returns True if user has - the global role and the project role - * arguments: user, role [project] -* role remove: removes role from user - * if project is specified, removes project specific role - * arguments: user, role [project] diff --git a/doc/build/html/_sources/adminguide/managingsecurity.txt b/doc/build/html/_sources/adminguide/managingsecurity.txt deleted file mode 100644 index 3b11b181a..000000000 --- a/doc/build/html/_sources/adminguide/managingsecurity.txt +++ /dev/null @@ -1,39 +0,0 @@ -.. - Copyright 2010 United States Government as represented by the - Administrator of the National Aeronautics and Space Administration. - All Rights Reserved. - - Licensed under the Apache License, Version 2.0 (the "License"); you may - not use this file except in compliance with the License.

This capability is similar to Amazon's 'elastic IPs'. A public IP address may be associated with a running instances, allowing the VM instance to be accessed from the public network. The public IP addresses are accessible from the network host and NATed to the private IP address of the project. - -.. todo:: Describe how a public IP address could be associated with a project (a VLAN) - -This is the default networking mode and supports the most features. For multiple machine installation, it requires a switch that supports host-managed vlan tagging. In this mode, nova will create a vlan and bridge for each project. The project gets a range of private ips that are only accessible from inside the vlan. In order for a user to access the instances in their project, a special vpn instance (code named :ref:`cloudpipe `) needs to be created.

Compute hosts create VLAN-specific interfaces and bridges -as required. - -The network nodes act as default gateway for project networks and contain -all of the routing and firewall rules implementing security groups. The -network node also handles DHCP to provide instance IPs for each project. - -VPN access is provided by running a small instance called CloudPipe -on the IP immediately following the gateway IP for each project. The -network node maps a dedicated public IP/port to the CloudPipe instance. - -Compute nodes have per-VLAN interfaces and bridges created as required. -These do NOT have IP addresses in the host to protect host access. -Compute nodes have iptables/ebtables entries created per project and -instance to protect against IP/MAC address spoofing and ARP poisoning. - -The network assignment to a project, and IP address assignment to a VM instance, are triggered when a user starts to run a VM instance. When running a VM instance, a user needs to specify a project for the instances, and the security groups (described in Security Groups) when the instance wants to join. If this is the first instance to be created for the project, then Nova (the cloud controller) needs to find a network controller to be the network host for the project; it then sets up a private network by finding an unused VLAN id, an unused subnet, and then the controller assigns them to the project, it also assigns a name to the project's Linux bridge, and allocating a private IP within the project's subnet for the new instance. - -If the instance the user wants to start is not the project's first, a subnet and a VLAN must have already been assigned to the project; therefore the system needs only to find an available IP address within the subnet and assign it to the new starting instance. If there is no private IP available within the subnet, an exception will be raised to the cloud controller, and the VM creation cannot proceed. - -.. todo:: insert the name of the Linux bridge, is it always named bridge? - -External Infrastructure ------------------------ - -Nova assumes the following is available: - -* DNS -* NTP -* Internet connectivity - - -Example -------- - -This example network configuration demonstrates most of the capabilities -of VLAN Mode.

Much like the electrical -power we receive each day, cloud computing is a model for enabling access to a shared collection of -computing resources - networks for transfer, servers for storage, and applications or services for -completing work. - -Why Cloud? ----------- -Like humans supposedly only use 10% of their brain power, many of the computers in place in data -centers today are underutilized in computing power and networking bandwidth. People also may need a large -amount of computing capacity to complete a computation for example, but don't need the computing power -once the computation is done. You want cloud computing when you want a service that's available -on-demand with the flexibility to bring it up or down through automation or with little intervention. - -Attributes of a Cloud ---------------------- -On-demand self-service - A cloud should enable self-service, so that users can provision servers and networks with little -human intervention. - -Network access - Any computing capabilities are available over the network and you can use many different -devices through standardized mechanisms. - -Resource pooling - Clouds can serve multiple consumers according to demand. - -Elasticity - Provisioning is rapid and scales out or in based on need. - -Metered or measured service - Just like utilities that are paid for by the hour, clouds should optimize -resource use and control it for the level of service or type of servers such as storage or processing. - -Types of Cloud Services ------------------------ - -Cloud computing offers different service models depending on the capabilities a consumer may require. -The US-based National Institute of Standards and Technology offers definitions for cloud computing -and the service models that are emerging. - -SaaS - Software as a Service -^^^^^^^^^^^^^^^^^^^^^^^^^^^^ - -Provides the consumer the ability to use the software in a cloud environment, such as web-based email for example. - -PaaS - Platform as a Service -^^^^^^^^^^^^^^^^^^^^^^^^^^^^ - -Provides the consumer the ability to deploy applications through a programming language or tools supported -by the cloud platform provider. An example of platform as a service is an Eclipse/Java programming -platform provided with no downloads required. - -IaaS - Infrastructure as a Service -^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ - -Provides infrastructure such as computer instances, network connections, and storage so that people -can run any software or operating system. - -.. todo:: Use definitions from

All of the major nova components can be run on multiple servers. This means that most component to component communication must go via message queue. In order to avoid blocking each component while waiting for a response, we use deferred objects, with a callback that gets triggered when a response is received. - -Nova recently moved to using a sql-based central database that is shared by all components in the system. The amount and depth of the data fits into a sql database quite well. For small deployments this seems like an optimal solution. For larger deployments, and especially if security is a concern, nova will be moving towards multiple data stores with some kind of aggregation system. - -Components ----------- - -Below you will find a helpful explanation of the different components. - -:: - - /- ( LDAP ) - [ Auth Manager ] --- - | \- ( DB ) - | - | [ scheduler ] - [ volume ] - ( ATAoE/iSCSI ) - | / - [ Web Dashboard ] -> [ api ] -- < AMQP > ------ [ network ] - ( Flat/Vlan ) - | \ - < HTTP > [ scheduler ] - [ compute ] - ( libvirt/xen ) - | | - [ objectstore ] < - retrieves images - -* DB: sql database for data storage.

The APIs can be logically grouped into sets that align with five typical roles: - -* Base User -* System Administrator/Developer (currently have the same permissions) -* Network Administrator -* Project Manager -* Cloud Administrator/IT-Security (currently have the same permissions) - -There is an additional, conceptual end-user that may or may not have API access: - -* (EXTERNAL) End-user / Third-party User - -Basic operations are available to any : - -* Describe Instances -* Describe Images -* Describe Volumes -* Describe Keypairs -* Create Keypair -* Delete Keypair -* Create, Upload, Delete: Buckets and Keys (Object Store) - -System Administrators/Developers/Project Manager: - -* Create, Attach, Delete Volume (Block Store) -* Launch, Reboot, Terminate Instance -* Register/Unregister Machine Image (project-wide) -* Request / Review CloudAudit Scans - -Project Manager: - -* Add and remove other users (currently no api) -* Set roles (currently no api) - -Network Administrator: - -* Change Machine Image properties (public / private) -* Change Firewall Rules, define Security Groups -* Allocate, Associate, Deassociate Public IP addresses - -Cloud Administrator/IT-Security: - -* All permissions - - -Enhancements ------------- - -* SAML Token passing -* REST interfaces -* SOAP interfaces - -Wrapping the SAML token into the API calls. -Then store the UID (fetched via backchannel) into the instance metadata, providing end-to-end auditability of ownership and responsibility, without PII. - - -CloudAudit APIs ---------------- - -* Request formats -* Response formats -* Stateless asynchronous queries - -CloudAudit queries may spawn long-running processes (similar to launching instances, etc.) They need to return a ReservationId in the same fashion, which can be returned in further queries for updates. -RBAC of CloudAudit API calls is critical, since detailed system information is a system vulnerability. - - -Type declarations ------------------ -* Data declarations – Volumes and Objects -* System declarations – Instances - -Existing API calls to launch instances specific a single, combined “type” flag. We propose to extend this with three additional type declarations, mapping to the “Confidentiality, Integrity, Availability” classifications of FIPS 199. An example API call would look like:: - - RunInstances type=m1.large number=1 secgroup=default key=mykey confidentiality=low integrity=low availability=low - -These additional parameters would also apply to creation of block storage volumes (along with the existing parameter of ‘size’), and creation of object storage ‘buckets’.

Access to this vpn is provided through a public port on the network host for the project. This allows users to have free access to the virtual machines in their project without exposing those machines to the public internet. - - -Cloudpipe Image ---------------- - -The cloudpipe image is basically just a linux instance with openvpn installed. It needs a simple script to grab user data from the metadata server, b64 decode it into a zip file, and run the autorun.sh script from inside the zip. The autorun script will configure and run openvpn to run using the data from nova. - -It is also useful to have a cron script that will periodically redownload the metadata and copy the new crl. This will keep revoked users from connecting and will disconnect any users that are connected with revoked certificates when their connection is renegotiated (every hour). - - -Cloudpipe Launch ----------------- - -When you use nova-manage to launch a cloudpipe for a user, it goes through the following process: - -#. creates a keypair called -vpn and saves it in the keys directory -#. creates a security group -vpn and opens up 1194 and icmp -#. creates a cert and private key for the vpn instance and saves it in the CA/projects// directory -#. zips up the info and puts it b64 encoded as user data -#. launches an m1.tiny instance with the above settings using the flag-specified vpn image - - -Vpn Access ----------- - -In vlan networking mode, the second ip in each private network is reserved for the cloudpipe instance. This gives a consistent ip to the instance so that nova-network can create forwarding rules for access from the outside world. The network for each project is given a specific high-numbered port on the public ip of the network host. This port is automatically forwarded to 1194 on the vpn instance. - -If specific high numbered ports do not work for your users, you can always allocate and associate a public ip to the instance, and then change the vpn_public_ip and vpn_public_port in the database. This will be turned into a nova-manage command or a flag soon. - - -Certificates and Revocation ---------------------------- - -If the use_project_ca flag is set (required to for cloudpipes to work securely), then each project has its own ca. This ca is used to sign the certificate for the vpn, and is also passed to the user for bundling images. When a certificate is revoked using nova-manage, a new Certificate Revocation List (crl) is generated. As long as cloudpipe has an updated crl, it will block revoked users from connecting to the vpn. - - -The :mod:`nova.cloudpipe.pipelib` Module -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -.. automodule:: nova.cloudpipe.pipelib - :noindex: - :members: - :undoc-members: - :show-inheritance: - - -The :mod:`nova.api.cloudpipe` Module -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -.. automodule:: nova.api.cloudpipe - :noindex: - :members: - :undoc-members: - :show-inheritance: - - -The :mod:`nova.crypto` Module -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -.. automodule:: nova.crypto - :noindex: - :members: - :undoc-members: - :show-inheritance: - diff --git a/doc/build/html/_sources/devref/compute.txt b/doc/build/html/_sources/devref/compute.txt deleted file mode 100644 index db9ef6f34..000000000 --- a/doc/build/html/_sources/devref/compute.txt +++ /dev/null @@ -1,153 +0,0 @@ -.. - Copyright 2010 United States Government as represented by the - Administrator of the National Aeronautics and Space Administration. - All Rights Reserved. - - Licensed under the Apache License, Version 2.0 (the "License"); you may - not use this file except in compliance with the License.

It is similar in scope to Amazon EC2 and Rackspace -CloudServers. Nova does not include any virtualization software, rather it -defines drivers that interact with underlying virtualization mechanisms that -run on your host operating system, and exposes functionality over a web API. - -This document does not attempt to explain fundamental concepts of cloud -computing, IaaS, virtualization, or other related technologies. Instead, it -focuses on describing how Nova's implementation of those concepts is achieved. - -This page outlines concepts that you will need to understand as a user or -administrator of an OpenStack installation. Each section links to more more -detailed information in the :doc:`adminguide/index`, -but you'll probably want to read this section straight-through before tackling -the specifics presented in the administration guide. - - -Concept: Users and Projects ---------------------------- - -* access to images is limited by project -* access/secret are per user -* keypairs are per user -* quotas are per project - - -Concept: Virtualization ------------------------ - -* KVM -* UML -* XEN -* HyperV -* qemu - - -Concept: Instances ------------------- - -An 'instance' is a word for a virtual machine that runs inside the cloud. - -Concept: Storage ----------------- - -Volumes -~~~~~~~ - -A 'volume' is a detachable block storage device. You can think of it as a usb hard drive. It can only be attached to one instance at a time, so it does not work like a SAN. If you wish to expose the same volume to multiple instances, you will have to use an NFS or SAMBA share from an existing instance. - -Local Storage -~~~~~~~~~~~~~ - -Every instance larger than m1.tiny starts with some local storage (up to 160GB for m1.xlarge). This storage is currently the second partition on the root drive. - -Concept: Quotas ---------------- - -Nova supports per-project quotas. There are currently quotas for number of instances, total number of cores, number of volumes, total number of gigabytes, and number of floating ips. - - -Concept: RBAC -------------- - -Nova provides roles based access control (RBAC) for access to api commands. A user can have a number of different :ref:`roles `. Roles define which api_commands a user can perform. - -It is important to know that there are user-specific (sometimes called global) roles and project-specific roles. A user's actual permissions in a particular project are the INTERSECTION of his user-specific roles and is project-specific roles. - -For example: A user can access api commands allowed to the netadmin role (like allocate_address) only if he has the user-specific netadmin role AND the project-specific netadmin role. - -More information about RBAC can be found in the :ref:`auth`. - -Concept: API ------------- - -* EC2 -* OpenStack / Rackspace - - -Concept: Networking -------------------- - -Nova has a concept of Fixed Ips and Floating ips. Fixed ips are assigned to an instance on creation and stay the same until the instance is explicitly terminated. Floating ips are ip addresses that can be dynamically associated with an instance. This address can be disassociated and associated with another instance at any time. - -There are multiple strategies available for implementing fixed ips: - -Flat Mode -~~~~~~~~~ - -The simplest networking mode. Each instance receives a fixed ip from the pool. All instances are attached to the same bridge (br100) by default. The bridge must be configured manually. The networking configuration is injected into the instance before it is booted. Note that this currently only works on linux-style systems that keep networking configuration in /etc/network/interfaces. - -Flat DHCP Mode -~~~~~~~~~~~~~~ - -This is similar to the flat mode, in that all instances are attached to the same bridge. In this mode nova does a bit more configuration, it will attempt to bridge into an ethernet device (eth0 by default). It will also run dnsmasq as a dhcpserver listening on this bridge. Instances receive their fixed ips by doing a dhcpdiscover. - -VLAN DHCP Mode -~~~~~~~~~~~~~~ - -This is the default networking mode and supports the most features. For multiple machine installation, it requires a switch that supports host-managed vlan tagging. In this mode, nova will create a vlan and bridge for each project. The project gets a range of private ips that are only accessible from inside the vlan. In order for a user to access the instances in their project, a special vpn instance (code named :ref:`cloudpipe `) needs to be created. Nova generates a certificate and key for the user to access the vpn and starts the vpn automatically. More information on cloudpipe can be found :ref:`here `. - -The following diagram illustrates how the communication that occurs between the vlan (the dashed box) and the public internet (represented by the two clouds) - -.. image:: /images/cloudpipe.png - :width: 100% - -.. - -Concept: Binaries ------------------ - -Nova is implemented by a number of related binaries. These binaries can run on the same machine or many machines. A detailed description of each binary is given in the :ref:`binaries section ` of the developer guide. - -.. _manage_usage: - -Concept: nova-manage --------------------- - -The nova-manage command is used to perform many essential functions for -administration and ongoing maintenance of nova, such as user creation, -vpn management, and much more. - -See doc:`nova.manage` in the Administration Guide for more details. - - -Concept: Flags --------------- - -python-gflags - - -Concept: Plugins ----------------- - -* Managers/Drivers: utils.import_object from string flag -* virt/connections: conditional loading from string flag -* db: LazyPluggable via string flag -* auth_manager: utils.import_class based on string flag -* Volumes: moving to pluggable driver instead of manager -* Network: pluggable managers -* Compute: same driver used, but pluggable at connection - - -Concept: IPC/RPC ----------------- - -Nova utilizes the RabbitMQ implementation of the AMQP messaging standard for performing communication between the various nova services. This message queuing service is used for both local and remote communication because Nova is designed so that there is no requirement that any of the services exist on the same physical machine. RabbitMQ in particular is very robust and provides the efficiency and reliability that Nova needs.

This API Server makes command and control of the hypervisor, storage, and networking programmatically available to users in realization of the definition of cloud computing. - -The API endpoints are basic http web services which handle authentication, authorization, and basic command and control functions using various API interfaces under the Amazon, Rackspace, and related models. This enables API compatibility with multiple existing tool sets created for interaction with offerings from other vendors. This broad compatibility prevents vendor lock-in. - -Message Queue --------------------------------------------------- -A messaging queue brokers the interaction between compute nodes (processing), volumes (block storage), the networking controllers (software which controls network infrastructure), API endpoints, the scheduler (determines which physical hardware to allocate to a virtual resource), and similar components. Communication to and from the cloud controller is by HTTP requests through multiple API endpoints. - -A typical message passing event begins with the API server receiving a request from a user. The API server authenticates the user and ensures that the user is permitted to issue the subject command. Availability of objects implicated in the request is evaluated and, if available, the request is routed to the queuing engine for the relevant workers. Workers continually listen to the queue based on their role, and occasionally their type hostname. When such listening produces a work request, the worker takes assignment of the task and begins its execution. Upon completion, a response is dispatched to the queue which is received by the API server and relayed to the originating user. Database entries are queried, added, or removed as necessary throughout the process. - -Compute Worker --------------------------------------------------- -Compute workers manage computing instances on host machines. Through the API, commands are dispatched to compute workers to: - -* Run instances -* Terminate instances -* Reboot instances -* Attach volumes -* Detach volumes -* Get console output - -Network Controller --------------------------------------------------- -The Network Controller manages the networking resources on host machines. The API server dispatches commands through the message queue, which are subsequently processed by Network Controllers. Specific operations include: - -* Allocate Fixed IP Addresses -* Configuring VLANs for projects -* Configuring networks for compute nodes - -Volume Workers --------------------------------------------------- -Volume Workers interact with iSCSI storage to manage LVM-based instance volumes. Specific functions include: - -* Create Volumes -* Delete Volumes -* Establish Compute volumes - -Volumes may easily be transferred between instances, but may be attached to only a single instance at a time. - - -.. todo:: P2: image store description diff --git a/doc/build/html/_static/basic.css b/doc/build/html/_static/basic.css deleted file mode 100644 index 69f30d4fb..000000000 --- a/doc/build/html/_static/basic.css +++ /dev/null @@ -1,509 +0,0 @@ -/* - * basic.css - * ~~~~~~~~~ - * - * Sphinx stylesheet -- basic theme. - * - * :copyright: Copyright 2007-2010 by the Sphinx team, see AUTHORS. - * :license: BSD, see LICENSE for details. - * - */ - -/* -- main layout ----------------------------------------------------------- */ - -div.clearer { - clear: both;

            Nova Daemons

            -

            The configuration of these binaries relies on “flagfiles” using the google -gflags package:

            -
            $ nova-xxxxx --flagfile flagfile
            -
            -

            The binaries can all run on the same machine or be spread out amongst multiple boxes in a large deployment.

            -
            -

            nova-api

            -

            Nova api receives xml requests and sends them to the rest of the system. It is a wsgi app that routes and authenticate requests. It supports the ec2 and openstack apis.

            -
            -
            -

            nova-objectstore

            -

            Nova objectstore is an ultra simple file-based storage system for images that replicates most of the S3 Api. It will soon be replaced with glance and a simple image manager.

            -
            -
            -

            nova-compute

            -

            Nova compute is responsible for managing virtual machines. It loads a Service object which exposes the public methods on ComputeManager via rpc.

            -
            -
            -

            nova-volume

            -

            Nova volume is responsible for managing attachable block storage devices. It loads a Service object which exposes the public methods on VolumeManager via rpc.

            -
            -
            -

            nova-network

            -

            Nova network is responsible for managing floating and fixed ips, dhcp, bridging and vlans. It loads a Service object which exposes the public methods on one of the subclasses of NetworkManager. Different networking strategies are as simple as changing the network_manager flag:

            -
            $ nova-network --network_manager=nova.network.manager.FlatManager
            -
            -

            IMPORTANT: Make sure that you also set the network_manager on nova-api and nova_compute, since make some calls to network manager in process instead of through rpc. More information on the interactions between services, managers, and drivers can be found here

            Nova installation on CentOS 5.5

            -

            These are notes for installing OpenStack Compute on CentOS 5.5 and will be updated but are NOT final. Please test for accuracy and edit as you see fit.

            -

            The principle botleneck for running nova on centos in python 2.6. Nova is written in python 2.6 and CentOS 5.5. comes with python 2.4. We can not update python system wide as some core utilities (like yum) is dependent on python 2.4. Also very few python 2.6 modules are available in centos/epel repos.

            -
            -
            -

            Pre-reqs

            -

            Add euca2ools and EPEL repo first.:

            -
            cat >/etc/yum.repos.d/euca2ools.repo << EUCA_REPO_CONF_EOF
-[eucalyptus]
-name=euca2ools
-baseurl=http://www.eucalyptussoftware.com/downloads/repo/euca2ools/1.3.1/yum/centos/
-enabled=1
-gpgcheck=0
-
-EUCA_REPO_CONF_EOF
            -
            -
            rpm -Uvh 'http://download.fedora.redhat.com/pub/epel/5/i386/epel-release-5-4.noarch.rpm'
            -
            -

            Now install python2.6, kvm and few other libraries through yum:

            -
            yum -y  install dnsmasq  vblade kpartx kvm gawk iptables ebtables  bzr screen euca2ools  curl rabbitmq-server gcc gcc-c++ autoconf automake swig  openldap openldap-servers nginx  python26 python26-devel python26-distribute git openssl-devel  python26-tools mysql-server qemu kmod-kvm libxml2 libxslt libxslt-devel mysql-devel
            -
            -

            Then download the latest aoetools and then build(and install) it, check for the latest version on sourceforge, exact url will change if theres a new release:

            -
            wget -c http://sourceforge.net/projects/aoetools/files/aoetools/32/aoetools-32.tar.gz/download
-tar -zxvf aoetools-32.tar.gz
-cd aoetools-32
-make
-make install
            -
            -

            Add the udev rules for aoetools:

            -
            cat > /etc/udev/rules.d/60-aoe.rules << AOE_RULES_EOF
-SUBSYSTEM=="aoe", KERNEL=="discover",    NAME="etherd/%k", GROUP="disk", MODE="0220"
-SUBSYSTEM=="aoe", KERNEL=="err",    NAME="etherd/%k", GROUP="disk", MODE="0440"
-SUBSYSTEM=="aoe", KERNEL=="interfaces",    NAME="etherd/%k", GROUP="disk", MODE="0220"
-SUBSYSTEM=="aoe", KERNEL=="revalidate",    NAME="etherd/%k", GROUP="disk", MODE="0220"
-# aoe block devices
-KERNEL=="etherd*",       NAME="%k", GROUP="disk"
-AOE_RULES_EOF
            -
            -

            Load the kernel modules:

            -
            modprobe aoe
            -
            -
            modprobe kvm
            -
            -

            Now, install the python modules using easy_install-2.6, this ensures the installation are done against python 2.6

            -

            easy_install-2.6 twisted sqlalchemy mox greenlet carrot daemon eventlet tornado IPy routes lxml MySQL-python -python-gflags need to be downloaded and installed manually, use these commands (check the exact url for newer releases ):

            -
            wget -c "http://python-gflags.googlecode.com/files/python-gflags-1.4.tar.gz"
-tar -zxvf python-gflags-1.4.tar.gz
-cd python-gflags-1.4
-python2.6 setup.py install
-cd ..
            -
            -

            Same for python2.6-libxml2 module, notice the –with-python and –prefix flags. –with-python ensures we are building it against python2.6 (otherwise it will build against python2.4, which is default):

            -
            wget -c "ftp://xmlsoft.org/libxml2/libxml2-2.7.3.tar.gz"
-tar -zxvf libxml2-2.7.3.tar.gz
-cd libxml2-2.7.3
-./configure --with-python=/usr/bin/python26 --prefix=/usr
-make all
-make install
-cd python
-python2.6 setup.py install
-cd ..
            -
            -

            Installing on Ubuntu 10.04 (Lucid)

            -
            -

            Step 1: Install dependencies

            -

            Grab the latest code from launchpad:

            -
            bzr clone lp:nova
            -
            -

            Here’s a script you can use to install (and then run) Nova on Ubuntu or Debian (when using Debian, edit nova.sh to have USE_PPA=0):

            -
            -

            Todo

            -

            give a link to a stable releases page

            -
            -
            -
            -

            Step 2: Install dependencies

            -

            Nova requires rabbitmq for messaging and optionally you can use redis for storing state, so install these first.

            -

            Note: You must have sudo installed to run these commands as shown here.

            -
            sudo apt-get install rabbitmq-server redis-server
            -
            -

            You’ll see messages starting with “Reading package lists... Done” and you must confirm by typing Y that you want to continue.

            -

            If you’re running on Ubuntu 10.04, you’ll need to install Twisted and python-gflags which is included in the OpenStack PPA.

            -
            sudo apt-get install python-twisted
-
-sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 95C71FE2
-sudo sh -c 'echo "deb http://ppa.launchpad.net/openstack/openstack-ppa/ubuntu lucid main" > /etc/apt/sources.list.d/openstackppa.list'
-sudo apt-get update && sudo apt-get install python-gflags
            -
            -

            -

            Single Machine Installation (Ubuntu 10.10)

            -

            While we wouldn’t expect you to put OpenStack Compute into production on a non-LTS version of Ubuntu, these instructions are up-to-date with the latest version of Ubuntu.

            -

            Make sure you are running Ubuntu 10.10 so that the packages will be available. This install requires more than 70 MB of free disk space.

            -

            These instructions are based on Soren Hansen’s blog entry, Openstack on Maverick. A script is in progress as well.

            -
            -

            Step 1: Install required prerequisites

            -

            Nova requires rabbitmq for messaging and redis for storing state (for now), so we’ll install these first.:

            -
            sudo apt-get install rabbitmq-server redis-server
            -
            -

            You’ll see messages starting with “Reading package lists... Done” and you must confirm by typing Y that you want to continue.

            -
            -
            -

            Step 2: Install Nova packages available in Maverick Meerkat

            -

            Type or copy/paste in the following line to get the packages that you use to run OpenStack Compute.:

            -
            sudo apt-get install python-nova
-sudo apt-get install nova-api nova-objectstore nova-compute nova-scheduler nova-network euca2ools unzip
            -
            -

            You’ll see messages starting with “Reading package lists... Done” and you must confirm by typing Y that you want to continue. This operation may take a while as many dependent packages will be installed. Note: there is a dependency problem with python-nova which can be worked around by installing first.

            -

            When the installation is complete, you’ll see the following lines confirming::

            -
            Adding system user `nova' (UID 106) ...
-Adding new user `nova' (UID 106) with group `nogroup' ...
-Not creating home directory `/var/lib/nova'.
-Setting up nova-scheduler (0.9.1~bzr331-0ubuntu2) ...
- * Starting nova scheduler nova-scheduler
-WARNING:root:Starting scheduler node
-   ...done.
-Processing triggers for libc-bin ...
-ldconfig deferred processing now taking place
-Processing triggers for python-support ...
            -
            -

            Once you’ve done this, continue at Step 3 here: Installing Nova on a Single Host

            Getting Started with Nova

            -

            This code base is continually changing, so dependencies also change. If you -encounter any problems, see the Getting Involved page. -The contrib/nova.sh script should be kept up to date, and may be a good -resource to review when debugging.

            -

            The purpose of this document is to get a system installed that you can use to -test your setup assumptions. Working from this base installtion you can -tweak configurations and work with different flags to monitor interaction with -your hardware, network, and other factors that will allow you to determine -suitability for your deployment. After following this setup method, you should -be able to experiment with different managers, drivers, and flags to get the -best performance.

            Related servers we rely on

            -
              -
            • RabbitMQ: messaging queue, used for all communication between components
              • -
            -

            Optional servers

            -
              -
            • OpenLDAP: By default, the auth server uses the RDBMS-backed datastore by -setting FLAGS.auth_driver to nova.auth.dbdriver.DbDriver. But OpenLDAP -(or LDAP) could be configured by specifying nova.auth.ldapdriver.LdapDriver. -There is a script in the sources (nova/auth/slap.sh) to install a very basic -openldap server on ubuntu.
              • -
            • ReDIS: There is a fake ldap auth driver -nova.auth.ldapdriver.FakeLdapDriver that backends to redis. This was -created for testing ldap implementation on systems that don’t have an easy -means to install ldap.
              • -
            • MySQL: Either MySQL or another database supported by sqlalchemy needs to -be avilable. Currently, only sqlite3 an mysql have been tested.
              • -
            -

            Nova uses cutting-edge versions of many packages. There are ubuntu packages in -the nova-core ppa. You can use add this ppa to your sources list on an ubuntu -machine with the following commands:

            -
            sudo apt-get install -y python-software-properties
-sudo add-apt-repository ppa:nova-core/ppa
            -
            -
            - -
            -

            Installation

            -

            You can install from packages for your particular Linux distribution if they are -available. Otherwise you can install from source by checking out the source -files from the Nova Source Code Repository -and running:

            -
            python setup.py install
            -
            -
            -
            -

            Configuration

            -
            -

            Configuring the host system

            -

            As you read through the Administration Guide you will notice configuration hints -inline with documentation on the subsystem you are configuring. Presented in -this “Getting Started with Nova” document, we only provide what you need to -get started as quickly as possible. For a more detailed description of system -configuration, start reading through Installing Nova on Multiple Servers.

            -
              -

            • Create a volume group (you can use an actual disk for the volume group as -well):

              -
              # This creates a 1GB file to create volumes out of
-dd if=/dev/zero of=MY_FILE_PATH bs=100M count=10
-losetup --show -f MY_FILE_PATH
-# replace /dev/loop0 below with whatever losetup returns
-# nova-volumes is the default for the --volume_group flag
-vgcreate nova-volumes /dev/loop0
              -
              -
              • -

            -

            Configuring Nova

            -

            Configuration of the entire system is performed through python-gflags. The -best way to track configuration is through the use of a flagfile.

            -

            A flagfile is specified with the --flagfile=FILEPATH argument to the binary -when you launch it. Flagfiles for nova are typically stored in -/etc/nova/nova.conf, and flags specific to a certain program are stored in -/etc/nova/nova-COMMAND.conf. Each configuration file can include another -flagfile, so typically a file like nova-manage.conf would have as its first -line --flagfile=/etc/nova/nova.conf to load the common flags before -specifying overrides or additional options.

            -

            A sample configuration to test the system follows:

            -
            --verbose
---nodaemon
---FAKE_subdomain=ec2
---auth_driver=nova.auth.dbdriver.DbDriver
-
            -
            -
            -
            -
            -

            Running

            -

            There are many parts to the nova system, each with a specific function. They -are built to be highly-available, so there are may configurations they can be -run in (ie: on many machines, many listeners per machine, etc). This part -of the guide only gets you started quickly, to learn about HA options, see -Installing Nova on Multiple Servers.

            -

            Launch supporting services

            Administration Guide

            -

            This guide describes the basics of running and managing Nova.

            -
            -

            Running the Cloud

            -

            The fastest way to get a test cloud running is by following the directions in the Nova Quickstart.

            -

            Nova’s cloud works via the interaction of a series of daemon processes that reside persistently on the host machine(s). Fortunately, the Nova Quickstart process launches sample versions of all these daemons for you. Once you are familiar with basic Nova usage, you can learn more about daemons by reading Service Architecture and Nova Daemons.

            -

            Administration Utilities

            -

            There are two main tools that a system administrator will find useful to manage their Nova cloud:

            -
            - -
            -

            nova-manage may only be run by users with admin priviledges. euca2ools can be used by all users, though specific commands may be restricted by Role Based Access Control. You can read more about creating and managing users in Managing Users

            -
            -
            -

            User and Resource Management

            -

            nova-manage and euca2ools provide the basic interface to perform a broad range of administration functions. In this section, you can read more about how to accomplish specific administration tasks.

            Keypairs

            -

            Images can be shared by many users, so it is dangerous to put passwords into the images. Nova therefore supports injecting ssh keys into instances before they are booted. This allows a user to login to the instances that he or she creates securely. Generally the first thing that a user does when using the system is create a keypair. Nova generates a public and private key pair, and sends the private key to the user. The public key is stored so that it can be injected into instances.

            -

            Keypairs are created through the api. They can be created on the command line using the euca2ools script euca-add-keypair. Refer to the man page for the available options. Example usage:

            -
            euca-add-keypair test > test.pem
-chmod 600 test.pem
-euca-run-instances -k test -t m1.tiny ami-tiny
-# wait for boot
-ssh -i test.pem root@ip.of.instance
            -
            -
            -
            -

            Basic Management

            -

            Instance management can be accomplished with euca commands:

            -

            To run an instance:

            -
            euca-run-instances
-
            -
            -

            To terminate an instance:

            -
            euca-terminate-instances
-
            -
            -

            To reboot an instance:

            -
            euca-reboot-instances
-
            -
            -

            See the euca2ools documentation for more information

            Networking Overview

            -

            In Nova, users organize their cloud resources in projects. A Nova project consists of a number of VM instances created by a user. For each VM instance, Nova assigns to it a private IP address. (Currently, Nova only supports Linux bridge networking that allows the virtual interfaces to connect to the outside network through the physical interface. Other virtual network technologies, such as Open vSwitch, could be supported in the future.) The Network Controller provides virtual networks to enable compute servers to interact with each other and with the public network.

            -
            -

            Nova Network Strategies

            -

            Currently, Nova supports three kinds of networks, implemented in three “Network Manager” types respectively: Flat Network Manager, Flat DHCP Network Manager, and VLAN Network Manager. The three kinds of networks can c-exist in a cloud system. However, the scheduler for selecting the type of network for a given project is not yet implemented. Here is a brief description of each of the different network strategies, with a focus on the VLAN Manager in a separate section.

            -

            Managing Projects

            -

            Projects are isolated resource containers forming the principal organizational structure within Nova. They consist of a separate vlan, volumes, instances, images, keys, and users.

            -

            Although the original ec2 api only supports users, nova adds the concept of projects. A user can specify which project he or she wishes to use by appending :project_id to his or her access key. If no project is specified in the api request, nova will attempt to use a project with the same id as the user.

            -

            The api will return NotAuthorized if a normal user attempts to make requests for a project that he or she is not a member of. Note that admins or users with special admin roles skip this check and can make requests for any project.

            -
            -
            To create a project, use the project create command of nova-manage. The syntax is nova-manage project create projectname manager_id [description] You must specify a projectname and a manager_id. For example::
            -
            nova-manage project create john_project john “This is a sample project”
            -
            You can add and remove users from projects with project add and project remove::
            -
            nova-manage project add john_project john -nova-manage project remove john_project john
            -

            Setting Quotas

            -

            Nova utilizes a quota system at the project level to control resource consumption across available hardware resources. Current quota controls are available to limit the:

            -
              -
            • Number of volumes which may be created
              • -
            • Total size of all volumes within a project as measured in GB
              • -
            • Number of instances which may be launched
              • -
            • Number of processor cores which may be allocated

            Users and Access Keys

            -

            Access to the ec2 api is controlled by an access and secret key. The user’s access key needs to be included in the request, and the request must be signed with the secret key. Upon receipt of api requests, nova will verify the signature and execute commands on behalf of the user.

            -

            In order to begin using nova, you will need a to create a user. This can be easily accomplished using the user create or user admin commands in nova-manage. user create will create a regular user, whereas user admin will create an admin user. The syntax of the command is nova-manage user create username [access] [secret]. For example:

            -
            nova-manage user create john my-access-key a-super-secret-key
            -
            -

            If you do not specify an access or secret key, a random uuid will be created automatically.

            -
            -
            -

            Credentials

            -

            Nova can generate a handy set of credentials for a user. These credentials include a CA for bundling images and a file for setting environment variables to be used by euca2ools. If you don’t need to bundle images, just the environment script is required. You can export one with the project environment command. The syntax of the command is nova-manage project environment project_id user_id [filename]. If you don’t specify a filename, it will be exported as novarc. After generating the file, you can simply source it in bash to add the variables to your environment:

            -
            nova-manage project environment john_project john
-. novarc
            -
            -

            If you do need to bundle images, you will need to get all of the credentials using project zipfile. Note that zipfile will give you an error message if networks haven’t been created yet. Otherwise zipfile has the same syntax as environment, only the default file name is nova.zip. Example usage:

            -
            nova-manage project zipfile john_project john
-unzip nova.zip
-. novarc
            -
            -
            -
            -

            Role Based Access Control

            -

            Roles control the api actions that a user is allowed to perform. For example, a user cannot allocate a public ip without the netadmin role. It is important to remember that a users de facto permissions in a project is the intersection of user (global) roles and project (local) roles. So for john to have netadmin permissions in his project, he needs to separate roles specified. You can add roles with role add. The syntax is nova-manage role add user_id role [project_id]. Let’s give john the netadmin role for his project:

            -
            nova-manage role add john netadmin
-nova-manage role add john netadmin john_project
            -
            -

            Role-based access control (RBAC) is an approach to restricting system access to authorized users based on an individual’s role within an organization. Various employee functions require certain levels of system access in order to be successful. These functions are mapped to defined roles and individuals are categorized accordingly. Since users are not assigned permissions directly, but only acquire them through their role (or roles), management of individual user rights becomes a matter of assigning appropriate roles to the user. This simplifies common operations, such as adding a user, or changing a user’s department.

            -

            Nova’s rights management system employs the RBAC model and currently supports the following five roles:

            -
              -
            • Cloud Administrator. (admin) Users of this class enjoy complete system access.
              • -
            • IT Security. (itsec) This role is limited to IT security personnel. It permits role holders to quarantine instances.
              • -
            • Project Manager. (projectmanager)The default for project owners, this role affords users the ability to add other users to a project, interact with project images, and launch and terminate instances.
              • -
            • Network Administrator. (netadmin) Users with this role are permitted to allocate and assign publicly accessible IP addresses as well as create and modify firewall rules.
              • -
            • Developer. This is a general purpose role that is assigned to users by default.
              • -
            -

            RBAC management is exposed through the dashboard for simplified user management.

            This doc is vague and just high-level right now. Describe architecture that enables security.

            -
            -

            The goal of securing a cloud computing system involves both protecting the instances, data on the instances, and -ensuring users are authenticated for actions and that borders are understood by the users and the system. -Protecting the system from intrusion or attack involves authentication, network protections, and -compromise detection.

            -
            -

            Key Concepts

            -

            Authentication - Each instance is authenticated with a key pair.

            -

            Network - Instances can communicate with each other but you can configure the boundaries through firewall -configuration.

            -

            Monitoring - Log all API commands and audit those logs.

            -

            Encryption - Data transfer between instances is not encrypted.

            Installing Nova on Multiple Servers

            -

            When you move beyond evaluating the technology and into building an actual -production environemnt, you will need to know how to configure your datacenter -and how to deploy components across your clusters. This guide should help you -through that process.

            -

            You can install multiple nodes to increase performance and availability of the OpenStack Compute installation.

            -

            This setup is based on an Ubuntu Lucid 10.04 installation with the latest updates. Most of this works around issues that need to be resolved in the installation and configuration scripts as of October 18th 2010. It also needs to eventually be generalized, but the intent here is to get the multi-node configuration bootstrapped so folks can move forward.

            -
            -

            Requirements for a multi-node installation

            -
              -
            • You need a real database, compatible with SQLAlchemy (mysql, postgresql) There’s not a specific reason to choose one over another, it basically depends what you know. MySQL is easier to do High Availability (HA) with, but people may already know Postgres. We should document both configurations, though.
              • -
            • For a recommended HA setup, consider a MySQL master/slave replication, with as many slaves as you like, and probably a heartbeat to kick one of the slaves into being a master if it dies.
              • -
            • For performance optimization, split reads and writes to the database. MySQL proxy is the easiest way to make this work if running MySQL.
              • -
            -
            -

            Assumptions

            -
              -
            • Networking is configured between/through the physical machines on a single subnet.
              • -
            • Installation and execution are both performed by root user.
              • -

            -

            It is highly likely that there will be errors when the nova services come up since they are not yet configured. Don’t worry, you’re only at step 1!

            -
            -
            -

            Step 2 Setup configuration files (installed in /etc/nova)

            -

            Note: CC_ADDR=<the external IP address of your cloud controller>

            -
              -
            1. These need to be defined in EACH configuration file
              2. -
            -
            --sql_connection=mysql://root:nova@$CC_ADDR/nova # location of nova sql db
---s3_host=$CC_ADDR  # This is where nova is hosting the objectstore service, which
-                    # will contain the VM images and buckets
---rabbit_host=$CC_ADDR # This is where the rabbit AMQP messaging service is hosted
---cc_host=$CC_ADDR     # This is where the the nova-api service lives
---verbose              # Optional but very helpful during initial setup
---ec2_url=http://$CC_ADDR:8773/services/Cloud
---network_manager=nova.network.manager.FlatManager # simple, no-vlan networking type

-
            -
            -
              -
            1. Create a nova group
              2. -
            -
            sudo addgroup nova
            -

              2. -
            -

            Config files should be have their owner set to root:nova, and mode set to 0640, since they contain your MySQL server’s root password.

            -
            cd /etc/nova
-chown -R root:nova .
            -
            -
            -
            -

            Step 3 Setup the sql db

            -
              -
            1. First you ‘preseed’ (using vishy’s Nova Quickstart). Run this as root.
              2. -
            -
            sudo apt-get install bzr git-core
-sudo bash
-export MYSQL_PASS=nova
            -
            -
            cat <<MYSQL_PRESEED | debconf-set-selections
-mysql-server-5.1 mysql-server/root_password password $MYSQL_PASS
-mysql-server-5.1 mysql-server/root_password_again password $MYSQL_PASS
-mysql-server-5.1 mysql-server/start_on_boot boolean true
-MYSQL_PRESEED
            -
            -
              -
            1. Install mysql
              2. -
            -
            sudo apt-get install -y mysql-server
            -
            -
              -
            1. Edit /etc/mysql/my.cnf and set this line: bind-address=0.0.0.0 and then sighup or restart mysql
              2. -
            2. create nova’s db
              3. -
            -
            mysql -uroot -pnova -e 'CREATE DATABASE nova;'
            -
            -
              -
            1. Update the db to include user ‘root’@’%’
              2. -
            -
            mysql -u root -p nova
-GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' WITH GRANT OPTION;
-SET PASSWORD FOR 'root'@'%' = PASSWORD('nova');
            -
            -
              -
            1. branch and install Nova
              2. -
            -
            sudo -i
-cd ~
-export USE_MYSQL=1
-export MYSQL_PASS=nova
-git clone https://github.com/vishvananda/novascript.git
-cd novascript
-./nova.sh branch
-./nova.sh install
-./nova.sh run
            -
            -
            -
            -

            Step 4 Setup Nova environment

            -
            /usr/bin/python /usr/bin/nova-manage user admin <user_name>
-/usr/bin/python /usr/bin/nova-manage project create <project_name> <user_name>
-/usr/bin/python /usr/bin/nova-manage project create network
            -
            -

            Note: The nova-manage service assumes that the first IP address is your network (like 192.168.0.0), that the 2nd IP is your gateway (192.168.0.1), and that the broadcast is the very last IP in the range you defined (192.168.0.255). If this is not the case you will need to manually edit the sql db ‘networks’ table.o.

            -

            On running this command, entries are made in the ‘networks’ and ‘fixed_ips’ table. However, one of the networks listed in the ‘networks’ table needs to be marked as bridge in order for the code to know that a bridge exists. We ended up doing this manually, (update query fired directly in the DB). Is there a better way to mark a network as bridged?

            -

            Update: This has been resolved w.e.f 27/10. network is marked as bridged automatically based on the type of n/w manager selected.

            -
            -

            More networking details to create a network bridge for flat network

            -

            Nova defaults to a bridge device named ‘br100’. This needs to be created and somehow integrated into YOUR network. In my case, I wanted to keep things as simple as possible and have all the vm guests on the same network as the vm hosts (the compute nodes). Thus, I set the compute node’s external IP address to be on the bridge and added eth0 to that bridge. To do this, edit your network interfaces config to look like the following:

            -
            < begin /etc/network/interfaces >
-# The loopback network interface
-auto lo
-iface lo inet loopback
-
-# Networking for NOVA
-auto br100
-
-iface br100 inet dhcp
-       bridge_ports    eth0
-       bridge_stp      off
-       bridge_maxwait  0
-       bridge_fd       0
-< end /etc/network/interfaces >
            -
            -

            Next, restart networking to apply the changes:

            -
            sudo /etc/init.d/networking restart
            -
            -
            -
            -
            -

            Step 5: Create nova certs.

            -

            Generate the certs as a zip file:

            -
            mkdir creds
-sudo /usr/bin/python /usr/bin/nova-manage project zip admin admin creds/nova.zip
            -
            -

            you can get the rc file more easily with:

            -
            sudo /usr/bin/python /usr/bin/nova-manage project env admin admin creds/novarc
            -
            -

            unzip them in your home directory, and add them to your environment:

            -
            unzip creds/nova.zip
-echo ". creds/novarc" >> ~/.bashrc
-~/.bashrc
            -
            -
            -
            -

            Step 6 Restart all relevant services

            -

            Restart Libvirt:

            -
            sudo /etc/init.d/libvirt-bin restart
            -
            -

            Restart relevant nova services:

            -
            sudo /etc/init.d/nova-compute restart
-sudo /etc/init.d/nova-volume restart
            -
            -
            -

            Flat Network Mode (Original and Flat)

            -

            Flat network mode removes most of the complexity of VLAN mode by simply -bridging all instance interfaces onto a single network.

            -

            There are two variations of flat mode that differ mostly in how IP addresses -are given to instances.

            -
            -

            Original Flat Mode

            -

            IP addresses for VM instances are grabbed from a subnet specified by the network administrator, and injected into the image on launch. All instances of the system are attached to the same Linux networking bridge, configured manually by the network administrator both on the network controller hosting the network and on the computer controllers hosting the instances. To recap:

            -
              -
            • Each compute host creates a single bridge for all instances to use to attach to the external network.
              • -
            • The networking configuration is injected into the instance before it is booted or it is obtained by a guest agent installed in the instance.
              • -
            -

            Note that the configuration injection currently only works on linux-style systems that keep networking -configuration in /etc/network/interfaces.

            -
            -
            -

            Flat DHCP Mode

            -

            IP addresses for VM instances are grabbed from a subnet specified by the network administrator. Similar to the flat network, a single Linux networking bridge is created and configured manually by the network administrator and used for all instances. A DHCP server is started to pass out IP addresses to VM instances from the specified subnet. To recap:

            -
              -
            • Like flat mode, all instances are attached to a single bridge on the compute node.
              • -
            • In addition a DHCP server is running to configure instances.
              • -
            -
            -
            -

            Implementation

            -

            The network nodes do not act as a default gateway in flat mode. Instances -are given public IP addresses.

            -

            Compute nodes have iptables/ebtables entries created per project and -instance to protect against IP/MAC address spoofing and ARP poisoning.

            VLAN Network Mode

            -

            VLAN Network Mode is the default mode for Nova. It provides a private network -segment for each project’s instances that can be accessed via a dedicated -VPN connection from the Internet.

            -

            In this mode, each project gets its own VLAN, Linux networking bridge, and subnet. The subnets are specified by the network administrator, and are assigned dynamically to a project when required. A DHCP Server is started for each VLAN to pass out IP addresses to VM instances from the subnet assigned to the project. All instances belonging to one project are bridged into the same VLAN for that project. The Linux networking bridges and VLANs are created by Nova when required, described in more detail in Nova VLAN Network Management Implementation.

            -../_images/Novadiagram.png -

            While network traffic between VM instances belonging to the same VLAN is always open, Nova can enforce isolation of network traffic between different projects by enforcing one VLAN per project.

            In addition, the network administrator can specify a pool of public IP addresses that users may allocate and then assign to VMs, either at boot or dynamically at run-time. This capability is similar to Amazon’s ‘elastic IPs’. A public IP address may be associated with a running instances, allowing the VM instance to be accessed from the public network. The public IP addresses are accessible from the network host and NATed to the private IP address of the project.

            Describe how a public IP address could be associated with a project (a VLAN)

            -
            -

            This is the default networking mode and supports the most features. For multiple machine installation, it requires a switch that supports host-managed vlan tagging. In this mode, nova will create a vlan and bridge for each project. The project gets a range of private ips that are only accessible from inside the vlan. In order for a user to access the instances in their project, a special vpn instance (code named cloudpipe) needs to be created. Nova generates a certificate and key for the user to access the vpn and starts the vpn automatically. More information on cloudpipe can be found here.

            -

            The following diagram illustrates how the communication that occurs between the vlan (the dashed box) and the public internet (represented by the two clouds)

              -
            • Projects / cluster limited to available VLANs in switching infrastructure
              • -

            Implementation

            -

            Currently Nova segregates project VLANs using 802.1q VLAN tagging in the -switching layer. Compute hosts create VLAN-specific interfaces and bridges -as required.

            -

            The network nodes act as default gateway for project networks and contain -all of the routing and firewall rules implementing security groups. The -network node also handles DHCP to provide instance IPs for each project.

            -

            VPN access is provided by running a small instance called CloudPipe -on the IP immediately following the gateway IP for each project. The -network node maps a dedicated public IP/port to the CloudPipe instance.

            -

            Compute nodes have per-VLAN interfaces and bridges created as required. -These do NOT have IP addresses in the host to protect host access. -Compute nodes have iptables/ebtables entries created per project and -instance to protect against IP/MAC address spoofing and ARP poisoning.

            -

            The network assignment to a project, and IP address assignment to a VM instance, are triggered when a user starts to run a VM instance. When running a VM instance, a user needs to specify a project for the instances, and the security groups (described in Security Groups) when the instance wants to join. If this is the first instance to be created for the project, then Nova (the cloud controller) needs to find a network controller to be the network host for the project; it then sets up a private network by finding an unused VLAN id, an unused subnet, and then the controller assigns them to the project, it also assigns a name to the project’s Linux bridge, and allocating a private IP within the project’s subnet for the new instance.

            -

            If the instance the user wants to start is not the project’s first, a subnet and a VLAN must have already been assigned to the project; therefore the system needs only to find an available IP address within the subnet and assign it to the new starting instance. If there is no private IP available within the subnet, an exception will be raised to the cloud controller, and the VM creation cannot proceed.

            -

            insert the name of the Linux bridge, is it always named bridge?

            External Infrastructure

            -

            Nova assumes the following is available:

            -
              -
            • DNS
              • -
            • NTP
              • -
            • Internet connectivity
              • -
            -
            -
            -

            Example

            -

            This example network configuration demonstrates most of the capabilities -of VLAN Mode. It splits administrative access to the nodes onto a dedicated -management network and uses dedicated network nodes to handle all -routing and gateway functions.

            -

            It uses a 10GB network for instance traffic and a 1GB network for management.

            -
            -

            Hardware

            -
              -
            • All nodes have a minimum of two NICs for management and production.
                -
              • management is 1GB
                • -
              • production is 10GB
                • -
              • add additional NICs for bonding or HA/performance
                • -
              -
              • -
            • network nodes should have an additional NIC dedicated to public Internet traffic
              • -
            • switch needs to support enough simultaneous VLANs for number of projects
              • -
            • production network configured as 802.1q trunk on switch
              • -
            -
            -
            -

            Operation

            -

            The network node controls the project network configuration:

            -
              -
            • assigns each project a VLAN and private IP range
              • -
            • starts dnsmasq on project VLAN to serve private IP range
              • -
            • configures iptables on network node for default project access
              • -
            • launches CloudPipe instance and configures iptables access
              • -
            -

            When starting an instance the network node:

            -
              -
            • sets up a VLAN interface and bridge on each host as required when an -instance is started on that host
              • -
            • assigns private IP to instance
              • -
            • generates MAC address for instance
              • -
            • update dnsmasq with IP/MAC for instance
              • -
            -

            When starting an instance the compute node:

            -
              -
            • sets up a VLAN interface and bridge on each host as required when an -instance is started on that host
              • -
            -
            -
            -

            The nova-manage command

            -
            -

            Introduction

            -

            The nova-manage command is used to perform many essential functions for -administration and ongoing maintenance of nova, such as user creation, -vpn management, and much more.

            -

            The standard pattern for executing a nova-manage command is: -nova-manage <category> <command> [<args>]

            -

            For example, to obtain a list of all projects: -nova-manage project list

            -

            Run without arguments to see a list of available command categories: -nova-manage

            -

            Categories are user, project, role, shell, vpn, and floating. Detailed descriptions are below.

            -

            You can also run with a category argument such as user to see a list of all commands in that category: -nova-manage user

            -

            These sections describe the available categories and arguments for nova-manage.

            Installing Nova on a Single Host

            -

            Nova can be run on a single machine, and it is recommended that new users practice managing this type of installation before graduating to multi node systems.

            -

            The fastest way to get a test cloud running is through our Nova Quickstart. But for more detail on installing the system read this doc.

            -
            -

            Step 1 and 2: Get the latest Nova code system software

            -

            Depending on your system, the mehod for accomplishing this varies

            -
            - -
            -
            -
            -

            Step 3: Build and install Nova services

            -

            Switch to the base nova source directory.

            -

            Then type or copy/paste in the following line to compile the Python code for OpenStack Compute.

            -
            sudo python setup.py build
-sudo python setup.py install
            -
            -

            When the installation is complete, you’ll see the following lines:

            -
            Installing nova-network script to /usr/local/bin
-Installing nova-volume script to /usr/local/bin
-Installing nova-objectstore script to /usr/local/bin
-Installing nova-manage script to /usr/local/bin
-Installing nova-scheduler script to /usr/local/bin
-Installing nova-dhcpbridge script to /usr/local/bin
-Installing nova-compute script to /usr/local/bin
-Installing nova-instancemonitor script to /usr/local/bin
-Installing nova-api script to /usr/local/bin
-Installing nova-import-canonical-imagestore script to /usr/local/bin
-
-Installed /usr/local/lib/python2.6/dist-packages/nova-2010.1-py2.6.egg
-Processing dependencies for nova==2010.1
-Finished processing dependencies for nova==2010.1
            -
            -
            -
            -

            Step 4: Create a Nova administrator

            -

            Type or copy/paste in the following line to create a user named “anne.”:

            -
            sudo nova-manage user admin anne
            -
            -

            You see an access key and a secret key export, such as these made-up ones::

            -
            export EC2_ACCESS_KEY=4e6498a2-blah-blah-blah-17d1333t97fd
-export EC2_SECRET_KEY=0a520304-blah-blah-blah-340sp34k05bbe9a7
            -
            -
            -
            -

            Step 5: Create a project with the user you created

            -

            Type or copy/paste in the following line to create a project named IRT (for Ice Road Truckers, of course) with the newly-created user named anne.

            -
            sudo nova-manage project create IRT anne
            -
            -

            -
            -
            -
            -

            Step 6: Unzip the nova.zip

            -

            You should have a nova.zip file in your current working directory. Unzip it with this command:

            -
            unzip nova.zip
            -
            -

            You’ll see these files extract.

            -
            Archive:  nova.zip
- extracting: novarc
- extracting: pk.pem
- extracting: cert.pem
- extracting: nova-vpn.conf
- extracting: cacert.pem
            -
            -
            -
            -

            Step 7: Source the rc file

            -

            Type or copy/paste the following to source the novarc file in your current working directory.

            -
            . novarc
            -
            -
            -
            -

            Step 8: Pat yourself on the back :)

            -

            Congratulations, your cloud is up and running, you’ve created an admin user, retrieved the user’s credentials and put them in your environment.

            -

            Now you need an image.

            -
            -
            -

            Step 9: Get an image

            -

            To make things easier, we’ve provided a small image on the Rackspace CDN. Use this command to get it on your server.

            -
            wget http://c2477062.cdn.cloudfiles.rackspacecloud.com/images.tgz
            -
            -

            -
            -
            -
            -

            Step 10: Decompress the image file

            -

            Use this command to extract the image files::

            -
            tar xvzf images.tgz
            -
            -

            You get a directory listing like so::

            -
            images
-|-- aki-lucid
-|   |-- image
-|   `-- info.json
-|-- ami-tiny
-|   |-- image
-|   `-- info.json
-`-- ari-lucid
-    |-- image
-    `-- info.json
            -
            -
            -
            -

            Step 11: Send commands to upload sample image to the cloud

            Troubleshooting Installation

            -

            If you see an “error loading the config file ‘./openssl.cnf’” it means you can copy the openssl.cnf file to the location where Nova expects it and reboot, then try the command again.

            -
            cp /etc/ssl/openssl.cnf ~
-sudo reboot

            Cloud Computing 101

            -

            Originally the term cloud came from a diagram that contained a cloud-like shape to contain the -services that afforded computing power that was harnessed to get work done. Much like the electrical -power we receive each day, cloud computing is a model for enabling access to a shared collection of -computing resources - networks for transfer, servers for storage, and applications or services for -completing work.

            -
            -

            Why Cloud?

            -

            Like humans supposedly only use 10% of their brain power, many of the computers in place in data -centers today are underutilized in computing power and networking bandwidth. People also may need a large -amount of computing capacity to complete a computation for example, but don’t need the computing power -once the computation is done. You want cloud computing when you want a service that’s available -on-demand with the flexibility to bring it up or down through automation or with little intervention.

            -
            -
            -

            Attributes of a Cloud

            -

            On-demand self-service - A cloud should enable self-service, so that users can provision servers and networks with little -human intervention.

            -

            Network access - Any computing capabilities are available over the network and you can use many different -devices through standardized mechanisms.

            -

            Resource pooling - Clouds can serve multiple consumers according to demand.

            -

            Elasticity - Provisioning is rapid and scales out or in based on need.

            -

            Metered or measured service - Just like utilities that are paid for by the hour, clouds should optimize -resource use and control it for the level of service or type of servers such as storage or processing.

            -
            -
            -

            Types of Cloud Services

            -

            Cloud computing offers different service models depending on the capabilities a consumer may require. -The US-based National Institute of Standards and Technology offers definitions for cloud computing -and the service models that are emerging.

            -
            -

            SaaS - Software as a Service

            -

            Provides the consumer the ability to use the software in a cloud environment, such as web-based email for example.

            -
            -
            -

            PaaS - Platform as a Service

            -

            Provides the consumer the ability to deploy applications through a programming language or tools supported -by the cloud platform provider. An example of platform as a service is an Eclipse/Java programming -platform provided with no downloads required.

            -
            -
            -

            IaaS - Infrastructure as a Service

            -

            Provides infrastructure such as computer instances, network connections, and storage so that people -can run any software or operating system.

            -

            Nova System Architecture

            -

            Nova is built on a shared-nothing, messaging-based architecture. All of the major nova components can be run on multiple servers. This means that most component to component communication must go via message queue. In order to avoid blocking each component while waiting for a response, we use deferred objects, with a callback that gets triggered when a response is received.

            -

            Nova recently moved to using a sql-based central database that is shared by all components in the system. The amount and depth of the data fits into a sql database quite well. For small deployments this seems like an optimal solution. For larger deployments, and especially if security is a concern, nova will be moving towards multiple data stores with some kind of aggregation system.

            -

            Components

            -

            Below you will find a helpful explanation of the different components.

            • Web Dashboard: potential external component that talks to the api
              • -
            • api: component that receives http requests, converts commands and communicates with other components via the queue or http (in the case of objectstore)
              • -
            • Auth Manager: component responsible for users/projects/and roles. Can backend to DB or LDAP. This is not a separate binary, but rather a python class that is used by most components in the system.

              • -
            • volume: manages dynamically attachable block devices.
              • -
            • network: manages ip forwarding, bridges, and vlans

            Nova provides RBAC (Role-based access control) of the AWS-type APIs. We define the following roles:

            -

            Roles-Based Access Control of AWS-style APIs using SAML Assertions -“Achieving FIPS 199 Moderate certification of a hybrid cloud environment using CloudAudit and declarative C.I.A. classifications”

            -
            -
            -

            Introduction

            -

            We will investigate one method for integrating an AWS-style API with US eAuthentication-compatible federated authentication systems, to achieve access controls and limits based on traditional operational roles. -Additionally, we will look at how combining this approach, with an implementation of the CloudAudit APIs, will allow us to achieve a certification under FIPS 199 Moderate classification for a hybrid cloud environment.

            -
            -
            -

            Relationship of US eAuth to RBAC

            -

            Typical implementations of US eAuth authentication systems are structured as follows:

            -
            [ MS Active Directory or other federated LDAP user store ]
-      --> backends to…
-[ SUN Identity Manager or other SAML Policy Controller ]
-      --> maps URLs to groups…
-[ Apache Policy Agent in front of eAuth-secured Web Application ]
            -
            -

            In more ideal implementations, the remainder of the application-specific account information is stored either in extended schema on the LDAP server itself, via the use of a translucent LDAP proxy, or in an independent datastore keyed off of the UID provided via SAML assertion.

            -
            -
            -

            Roles

            -

            AWS API calls are traditionally secured via Access and Secret Keys, which are used to sign API calls, along with traditional timestamps to prevent replay attacks. The APIs can be logically grouped into sets that align with five typical roles:

            -
              -
            • Base User
              • -
            • System Administrator/Developer (currently have the same permissions)
              • -
            • Network Administrator
              • -
            • Project Manager
              • -
            • Cloud Administrator/IT-Security (currently have the same permissions)
              • -
            -

            There is an additional, conceptual end-user that may or may not have API access:

            -
              -
            • (EXTERNAL) End-user / Third-party User
              • -
            -

            Basic operations are available to any :

            -
              -
            • Add and remove other users (currently no api)

            CloudAudit APIs

            -
              -
            • Request formats
              • -
            • Response formats
              • -
            • Stateless asynchronous queries
              • -
            -

            CloudAudit queries may spawn long-running processes (similar to launching instances, etc.) They need to return a ReservationId in the same fashion, which can be returned in further queries for updates. -RBAC of CloudAudit API calls is critical, since detailed system information is a system vulnerability.

            -
            -
            -

            Type declarations

            -
              -
            • Data declarations – Volumes and Objects
              • -
            • System declarations – Instances
              • -
            -

            Existing API calls to launch instances specific a single, combined “type” flag. We propose to extend this with three additional type declarations, mapping to the “Confidentiality, Integrity, Availability” classifications of FIPS 199. An example API call would look like:

            -
            RunInstances type=m1.large number=1 secgroup=default key=mykey confidentiality=low integrity=low availability=low
            -
            -

            These additional parameters would also apply to creation of block storage volumes (along with the existing parameter of ‘size’), and creation of object storage ‘buckets’. (C.I.A. classifications on a bucket would be inherited by the keys within this bucket.)

            -
            -
            -

            Request Brokering

            -
              -
            • Cloud Interop
              • -
            • IMF Registration / PubSub
              • -
            • Digital C&A
              • -
            -

            Establishing declarative semantics for individual API calls will allow the cloud environment to seamlessly proxy these API calls to external, third-party vendors – when the requested CIA levels match.

            -

            See related work within the Infrastructure 2.0 working group for more information on how the IMF Metadata specification could be utilized to manage registration of these vendors and their C&A credentials.

            Dirty Cloud – Hybrid Data Centers

            -
              -
            • CloudAudit bridge interfaces
              • -
            • Anything in the ARP table
              • -
            -

            A hybrid cloud environment provides dedicated, potentially co-located physical hardware with a network interconnect to the project or users’ cloud virtual network.

            -

            This interconnect is typically a bridged VPN connection. Any machines that can be bridged into a hybrid environment in this fashion (at Layer 2) must implement a minimum version of the CloudAudit spec, such that they can be queried to provide a complete picture of the IT-sec runtime environment.

            -

            Network discovery protocols (ARP, CDP) can be applied in this case, and existing protocols (SNMP location data, DNS LOC records) overloaded to provide CloudAudit information.

            System limits

            -

            The following limits need to be defined and enforced:

            -
              -
            • Total number of instances allowed (user / project)
              • -
            • Total number of instances, per instance type (user / project)
              • -
            • Total number of volumes (user / project)
              • -
            • Maximum size of volume
              • -
            • Cumulative size of all volumes
              • -
            • Total use of object storage (GB)
              • -
            • Total number of Public IPs
              • -
            -

            Cloudpipe – Per Project Vpns

            -

            Cloudpipe is a method for connecting end users to their project insnances in vlan mode.

            -
            -

            Overview

            -

            The support code for cloudpipe implements admin commands (via nova-manage) to automatically create a vm for a project that allows users to vpn into the private network of their project. Access to this vpn is provided through a public port on the network host for the project. This allows users to have free access to the virtual machines in their project without exposing those machines to the public internet.

            -
            -
            -

            Cloudpipe Image

            -

            The cloudpipe image is basically just a linux instance with openvpn installed. It needs a simple script to grab user data from the metadata server, b64 decode it into a zip file, and run the autorun.sh script from inside the zip. The autorun script will configure and run openvpn to run using the data from nova.

            -

            It is also useful to have a cron script that will periodically redownload the metadata and copy the new crl. This will keep revoked users from connecting and will disconnect any users that are connected with revoked certificates when their connection is renegotiated (every hour).

            -
            -
            -

            Cloudpipe Launch

            -

            When you use nova-manage to launch a cloudpipe for a user, it goes through the following process:

            -
              -
            1. creates a keypair called <project_id>-vpn and saves it in the keys directory
              2. -
            2. creates a security group <project_id>-vpn and opens up 1194 and icmp
              3. -
            3. creates a cert and private key for the vpn instance and saves it in the CA/projects/<project_id>/ directory
              4. -
            4. zips up the info and puts it b64 encoded as user data
              5. -
            5. launches an m1.tiny instance with the above settings using the flag-specified vpn image
              6. -
            -
            -
            -

            Vpn Access

            -

            In vlan networking mode, the second ip in each private network is reserved for the cloudpipe instance. This gives a consistent ip to the instance so that nova-network can create forwarding rules for access from the outside world. The network for each project is given a specific high-numbered port on the public ip of the network host. This port is automatically forwarded to 1194 on the vpn instance.

            -

            If specific high numbered ports do not work for your users, you can always allocate and associate a public ip to the instance, and then change the vpn_public_ip and vpn_public_port in the database. This will be turned into a nova-manage command or a flag soon.

            -
            -
            -

            Certificates and Revocation

            -

            If the use_project_ca flag is set (required to for cloudpipes to work securely), then each project has its own ca. This ca is used to sign the certificate for the vpn, and is also passed to the user for bundling images. When a certificate is revoked using nova-manage, a new Certificate Revocation List (crl) is generated. As long as cloudpipe has an updated crl, it will block revoked users from connecting to the vpn.

            -
            -
            -class nova.virt.fake.FakeConnection
            -

            Bases: object

            -

            The interface to this class talks in terms of ‘instances’ (Amazon EC2 and -internal Nova terminology), by which we mean ‘running virtual machine’ -(XenAPI terminology) or domain (Xen or libvirt terminology).

            -

            An instance has an ID, which is the identifier chosen by Nova to represent -the instance further up the stack. This is unfortunately also called a -‘name’ elsewhere. As far as this layer is concerned, ‘instance ID’ and -‘instance name’ are synonyms.

            -

            Note that the instance ID or name is not human-readable or -customer-controlled – it’s an internal ID chosen by Nova. At the -nova.virt layer, instances do not have human-readable names at all – such -things are only known higher up the stack.

            -

            Most virtualization platforms will also have their own identity schemes, -to uniquely identify a VM or domain. These IDs must stay internal to the -platform-specific layer, and never escape the connection interface. The -platform-specific layer is responsible for keeping track of which instance -ID maps to which platform-specific ID, and vice versa.

            -

            In contrast, the list_disks and list_interfaces calls may return -platform-specific IDs. These identify a specific virtual disk or specific -virtual network interface, and these IDs are opaque to the rest of Nova.

            -

            Some methods here take an instance of nova.compute.service.Instance. This -is the datastructure used by nova.compute to store details regarding an -instance, and pass them into this layer. This layer is responsible for -translating that generic datastructure into terms that are specific to the -virtualization platform.

            -
            -
            -FakeConnection.attach_volume(instance_name, device_path, mountpoint)
            -

            Attach the disk at device_path to the instance at mountpoint

            -
            - -
            -
            -FakeConnection.block_stats(instance_name, disk_id)
            -

            Return performance counters associated with the given disk_id on the -given instance_name. These are returned as [rd_req, rd_bytes, wr_req, -wr_bytes, errs], where rd indicates read, wr indicates write, req is -the total number of I/O requests made, bytes is the total number of -bytes transferred, and errs is the number of requests held up due to a -full pipeline.

            -

            All counters are long integers.

            -

            This method is optional. On some platforms (e.g. XenAPI) performance -statistics can be retrieved directly in aggregate form, without Nova -having to do the aggregation. On those platforms, this method is -unused.

            -

            Note that this function takes an instance ID, not a -compute.service.Instance, so that it can be called by compute.monitor.

            - -
            -
            -FakeConnection.destroy(instance)

            Destroy (shutdown and delete) the specified instance.

            -

            The given parameter is an instance of nova.compute.service.Instance, -and so the instance is being specified as instance.name.

            -FakeConnection.detach_volume(instance_name, mountpoint)
            -

            -
            - -
            -
            -FakeConnection.get_info(instance_name)
            -

            Get a block of information about the given instance. This is returned -as a dictionary containing ‘state’: The power_state of the instance, -‘max_mem’: The maximum memory for the instance, in KiB, ‘mem’: The -current memory the instance has, in KiB, ‘num_cpu’: The current number -of virtual CPUs the instance has, ‘cpu_time’: The total CPU time used -by the instance, in nanoseconds.

            -

            This method should raise exception.NotFound if the hypervisor has no -knowledge of the instance

            -
            - -
            -
            -classmethod FakeConnection.instance()

            -
            -FakeConnection.interface_stats(instance_name, iface_id)
            -

            Return performance counters associated with the given iface_id on the -given instance_id. These are returned as [rx_bytes, rx_packets, -rx_errs, rx_drop, tx_bytes, tx_packets, tx_errs, tx_drop], where rx -indicates receive, tx indicates transmit, bytes and packets indicate -the total number of bytes or packets transferred, and errs and dropped -is the total number of packets failed / dropped.

            -

            All counters are long integers.

            -

            This method is optional. On some platforms (e.g. XenAPI) performance -statistics can be retrieved directly in aggregate form, without Nova -having to do the aggregation. On those platforms, this method is -unused.

            -

            -
            - -
            -
            -FakeConnection.list_disks(instance_name)
            -

            Return the IDs of all the virtual disks attached to the specified -instance, as a list. These IDs are opaque to the caller (they are -only useful for giving back to this layer as a parameter to -disk_stats). These IDs only need to be unique for a given instance.

            -

            Note that this function takes an instance ID, not a -compute.service.Instance, so that it can be called by compute.monitor.

            -FakeConnection.list_instances()

            -
            - -
            -
            -FakeConnection.list_interfaces(instance_name)
            -

            Return the IDs of all the virtual network interfaces attached to the -specified instance, as a list. These IDs are opaque to the caller -(they are only useful for giving back to this layer as a parameter to -interface_stats). These IDs only need to be unique for a given -instance.

            -

            Note that this function takes an instance ID, not a -compute.service.Instance, so that it can be called by compute.monitor.

            -FakeConnection.reboot(instance)
            -

            Reboot the specified instance.

            -

            The given parameter is an instance of nova.compute.service.Instance, -and so the instance is being specified as instance.name.

            -

            The work will be done asynchronously. This function returns a -Deferred that allows the caller to detect when it is complete.

            -
            - -
            -
            -FakeConnection.rescue(instance)
            -

            Rescue the specified instance.

            -
            - -
            -
            -FakeConnection.spawn(instance)
            -

            Create a new instance/VM/domain on the virtualization platform.

            -

            The given parameter is an instance of nova.compute.service.Instance. -This function should use the data there to guide the creation of -the new instance.

            -

            The work will be done asynchronously. This function returns a -Deferred that allows the caller to detect when it is complete.

            -

            Once this successfully completes, the instance should be -running (power_state.RUNNING).

            -

            If this fails, any partial instance should be completely -cleaned up, and the virtualization platform should be in the state -that it was before this call began.

            -
            - -
            -
            -FakeConnection.unrescue(instance)

            document general info about fakes

            -
            -

            When the real thing isn’t available and you have some development to do these -fake implementations of various drivers let you get on with your day.

            -
            -

            The nova.virt.fake Module

            -

            A fake (in-memory) hypervisor+api.

            -

            Allows nova testing w/o a hypervisor. This module also documents the -semantics of real hypervisor connections.

            -
            -
            -class nova.virt.fake.FakeConnection
            -

            Bases: object

            -

            The interface to this class talks in terms of ‘instances’ (Amazon EC2 and -internal Nova terminology), by which we mean ‘running virtual machine’ -(XenAPI terminology) or domain (Xen or libvirt terminology).

            -

            An instance has an ID, which is the identifier chosen by Nova to represent -the instance further up the stack. This is unfortunately also called a -‘name’ elsewhere. As far as this layer is concerned, ‘instance ID’ and -‘instance name’ are synonyms.

            -

            Note that the instance ID or name is not human-readable or -customer-controlled – it’s an internal ID chosen by Nova. At the -nova.virt layer, instances do not have human-readable names at all – such -things are only known higher up the stack.

            -

            Most virtualization platforms will also have their own identity schemes, -to uniquely identify a VM or domain. These IDs must stay internal to the -platform-specific layer, and never escape the connection interface. The -platform-specific layer is responsible for keeping track of which instance -ID maps to which platform-specific ID, and vice versa.

            -

            In contrast, the list_disks and list_interfaces calls may return -platform-specific IDs. These identify a specific virtual disk or specific -virtual network interface, and these IDs are opaque to the rest of Nova.

            -

            Some methods here take an instance of nova.compute.service.Instance. This -is the datastructure used by nova.compute to store details regarding an -instance, and pass them into this layer. This layer is responsible for -translating that generic datastructure into terms that are specific to the -virtualization platform.

            -
            -
            -FakeConnection.attach_volume(instance_name, device_path, mountpoint)
            -

            Attach the disk at device_path to the instance at mountpoint

            -
            - -
            -
            -FakeConnection.block_stats(instance_name, disk_id)
            -

            Return performance counters associated with the given disk_id on the -given instance_name. These are returned as [rd_req, rd_bytes, wr_req, -wr_bytes, errs], where rd indicates read, wr indicates write, req is -the total number of I/O requests made, bytes is the total number of -bytes transferred, and errs is the number of requests held up due to a -full pipeline.

            -

            All counters are long integers.

            -

            This method is optional. On some platforms (e.g. XenAPI) performance -statistics can be retrieved directly in aggregate form, without Nova -having to do the aggregation. On those platforms, this method is -unused.

            -

            Note that this function takes an instance ID, not a -compute.service.Instance, so that it can be called by compute.monitor.

            -
            - -
            -
            -FakeConnection.destroy(instance)
            -

            Destroy (shutdown and delete) the specified instance.

            -

            The given parameter is an instance of nova.compute.service.Instance, -and so the instance is being specified as instance.name.

            -

            The work will be done asynchronously. This function returns a -Deferred that allows the caller to detect when it is complete.

            -
            - -
            -
            -FakeConnection.detach_volume(instance_name, mountpoint)
            -

            Detach the disk attached to the instance at mountpoint

            -
            -FakeConnection.get_info(instance_name)
            -

            Get a block of information about the given instance. This is returned -as a dictionary containing ‘state’: The power_state of the instance, -‘max_mem’: The maximum memory for the instance, in KiB, ‘mem’: The -current memory the instance has, in KiB, ‘num_cpu’: The current number -of virtual CPUs the instance has, ‘cpu_time’: The total CPU time used -by the instance, in nanoseconds.

            -

            This method should raise exception.NotFound if the hypervisor has no -knowledge of the instance

            -
            - -

            -
            -FakeConnection.interface_stats(instance_name, iface_id)
            -

            Return performance counters associated with the given iface_id on the -given instance_id. These are returned as [rx_bytes, rx_packets, -rx_errs, rx_drop, tx_bytes, tx_packets, tx_errs, tx_drop], where rx -indicates receive, tx indicates transmit, bytes and packets indicate -the total number of bytes or packets transferred, and errs and dropped -is the total number of packets failed / dropped.

            -

            All counters are long integers.

            -
            -FakeConnection.list_disks(instance_name)
            -

            Return the IDs of all the virtual disks attached to the specified -instance, as a list. These IDs are opaque to the caller (they are -only useful for giving back to this layer as a parameter to -disk_stats). These IDs only need to be unique for a given instance.

            -

            -
            -FakeConnection.list_instances()

            - -
            -
            -FakeConnection.list_interfaces(instance_name)
            -

            Return the IDs of all the virtual network interfaces attached to the -specified instance, as a list. These IDs are opaque to the caller -(they are only useful for giving back to this layer as a parameter to -interface_stats). These IDs only need to be unique for a given -instance.

            -

            - -
            -
            -FakeConnection.reboot(instance)
            -

            Reboot the specified instance.

            -

            The given parameter is an instance of nova.compute.service.Instance, -and so the instance is being specified as instance.name.

            -

            The work will be done asynchronously. This function returns a -Deferred that allows the caller to detect when it is complete.

            -
            - -
            -
            -FakeConnection.rescue(instance)
            -

            Rescue the specified instance.

            -
            - -
            -
            -FakeConnection.spawn(instance)
            -

            Create a new instance/VM/domain on the virtualization platform.

            -

            The given parameter is an instance of nova.compute.service.Instance. -This function should use the data there to guide the creation of -the new instance.

            -

            The work will be done asynchronously. This function returns a -Deferred that allows the caller to detect when it is complete.

            -

            Once this successfully completes, the instance should be -running (power_state.RUNNING).

            -

            If this fails, any partial instance should be completely -cleaned up, and the virtualization platform should be in the state -that it was before this call began.

            -
            - -
            -
            -FakeConnection.unrescue(instance)

            Components

            -

            There are several key components:

            -
              -
            • NetworkController (Manages address and vlan allocation)
              • -
            • RoutingNode (NATs public IPs to private IPs, and enforces firewall rules)
              • -
            • AddressingNode (runs DHCP services for private networks)
              • -
            • BridgingNode (a subclass of the basic nova ComputeNode)
              • -
            • TunnelingNode (provides VPN connectivity)
              • -
            -
            -
            -

            Component Diagram

            -

            Overview:

            -
                                           (PUBLIC INTERNET)

-                 [RoutingNode] ... [RN]    [TunnelingNode] ... [TN]
-                       |             \    /       |              |
-                       |            < AMQP >      |              |
-[AddressingNode]--  (VLAN) ...         |        (VLAN)...    (VLAN)      --- [AddressingNode]
-                       \               |           \           /
-                      / \             / \         / \         / \
-                       [BridgingNode] ...          [BridgingNode]
-
-
-                 [NetworkController]   ...    [NetworkController]
-                                   \          /
-                                     < AMQP >
-                                        |
-                                       / \
-                      [CloudController]...[CloudController]
            -
            -

            While this diagram may not make this entirely clear, nodes and controllers communicate exclusively across the message bus (AMQP, currently).

            -
            -
            -

            State Model

            -

            Network State consists of the following facts:

            -
              -
            • VLAN assignment (to a project)
              • -
            • Private Subnet assignment (to a security group) in a VLAN
              • -
            • Private IP assignments (to running instances)
              • -
            • Public IP allocations (to a project)
              • -
            • Public IP associations (to a private IP / running instance)
              • -
            -

            While copies of this state exist in many places (expressed in IPTables rule chains, DHCP hosts files, etc), the controllers rely only on the distributed “fact engine” for state, queried over RPC (currently AMQP). The NetworkController inserts most records into this datastore (allocating addresses, etc) - however, individual nodes update state e.g. when running instances crash.

            -
            -
            -

            The Public Traffic Path

            -

            Public Traffic:

            -
                           (PUBLIC INTERNET)
-                      |
-                    <NAT>  <-- [RoutingNode]
-                      |
-[AddressingNode] -->  |
-                   ( VLAN )
-                      |    <-- [BridgingNode]
-                      |
-               <RUNNING INSTANCE>
            -
            -

            The RoutingNode is currently implemented using IPTables rules, which implement both NATing of public IP addresses, and the appropriate firewall chains. We are also looking at using Netomata / Clusto to manage NATting within a switch or router, and/or to manage firewall rules within a hardware firewall appliance.

            -

            Similarly, the AddressingNode currently manages running DNSMasq instances for DHCP services. However, we could run an internal DHCP server (using Scapy ala Clusto), or even switch to static addressing by inserting the private address into the disk image the same way we insert the SSH keys. (See compute for more details).

            Services, Managers and Drivers

            -

            The responsibilities of Services, Managers, and Drivers, can be a bit confusing to people that are new to nova. This document attempts to outline the division of responsibilities to make understanding the system a little bit easier.

            -

            Currently, Managers and Drivers are specified by flags and loaded using utils.load_object(). This method allows for them to be implemented as singletons, classes, modules or objects. As long as the path specified by the flag leads to an object (or a callable that returns an object) that responds to getattr, it should work as a manager or driver.

            Implementation-Specific Drivers

            -

            A manager will generally load a driver for some of its tasks. The driver is responsible for specific implementation details. Anything running shell commands on a host, or dealing with other non-python code should probably be happening in a driver.

            -

            Drivers should minimize touching the database, although it is currently acceptable for implementation specific data. This may be reconsidered at some point.

            -

            It usually makes sense to define an Abstract Base Class for the specific driver (i.e. VolumeDriver), to define the methods that a different driver would need to implement.

            Nova uses ata-over-ethernet (AoE) to export storage volumes from multiple storage nodes. These AoE exports are attached (using libvirt) directly to running instances.

            -

            Nova volumes are exported over the primary system VLAN (usually VLAN 1), and not over individual VLANs.

            -

            AoE exports are numbered according to a “shelf and blade” syntax. In order to avoid collisions, we currently perform an AoE-discover of existing exports, and then grab the next unused number. (This obviously has race condition problems, and should be replaced by allocating a shelf-id to each storage node.)

            -

            The underlying volumes are LVM logical volumes, created on demand within a single large volume group.

            Welcome to Nova’s documentation!

            -

            Nova is a cloud computing fabric controller, the main part of an IaaS system. -Individuals and organizations can use Nova to host and manage their own cloud -computing systems. Nova originated as a project out of NASA Ames Research Laboratory.

            -

            Nova is written with the following design guidelines in mind:

            -
              -
            • Component based architecture: Quickly add new behaviors
              • -
            • Highly available: Scale to very serious workloads
              • -
            • Fault-Tollerant: Isloated processes avoid cascading failures
              • -
            • Recoverable: Failures should be easy to diagnose, debug, and rectify
              • -
            • Open Standards: Be a reference implementation for a community-driven api
              • -
            • API Compatibility: Nova strives to provide API-compatible with popular systems like Amazon EC2
              • -
            -

            This documentation is generated by the Sphinx toolkit and lives in the source -tree. Additional documentation on Nova and other components of OpenStack can -be found on the OpenStack wiki. Also see the Getting Involved page for -other ways to interact with the community.

            DESCRIPTION

            -

            nova-manage controls cloud computing instances by managing nova users, nova projects, nova roles, shell selection, vpn connections, and floating IP address configuration. More information about OpenStack Nova is at http://nova.openstack.org.

            -
            -
            -

            OPTIONS

            -

            The standard pattern for executing a nova-manage command is: -nova-manage <category> <command> [<args>]

            -

            For example, to obtain a list of all projects: -nova-manage project list

            -

            Run without arguments to see a list of available command categories: -nova-manage

            -

            Categories are user, project, role, shell, vpn, and floating. Detailed descriptions are below.

            -

            You can also run with a category argument such as user to see a list of all commands in that category: -nova-manage user

            -

            These sections describe the available categories and arguments for nova-manage.

            Nova Concepts and Introduction

            -
            -

            Introduction

            -

            Nova is the software that controls your Infrastructure as as Service (IaaS) -cloud computing platform. It is similar in scope to Amazon EC2 and Rackspace -CloudServers. Nova does not include any virtualization software, rather it -defines drivers that interact with underlying virtualization mechanisms that -run on your host operating system, and exposes functionality over a web API.

            -

            This document does not attempt to explain fundamental concepts of cloud -computing, IaaS, virtualization, or other related technologies. Instead, it -focuses on describing how Nova’s implementation of those concepts is achieved.

            -

            This page outlines concepts that you will need to understand as a user or -administrator of an OpenStack installation. Each section links to more more -detailed information in the Administration Guide, -but you’ll probably want to read this section straight-through before tackling -the specifics presented in the administration guide.

            Concept: Users and Projects

            -
              -
            • access to images is limited by project
              • -
            • access/secret are per user
              • -
            • keypairs are per user
              • -
            • quotas are per project
              • -
            -
            -
            -

            Concept: Virtualization

            -
              -
            • KVM
              • -
            • UML
              • -
            • XEN

            -
            -
            -

            Concept: Instances

            -

            An ‘instance’ is a word for a virtual machine that runs inside the cloud.

            -
            -
            -

            Concept: Storage

            -
            -

            Volumes

            -

            A ‘volume’ is a detachable block storage device. You can think of it as a usb hard drive. It can only be attached to one instance at a time, so it does not work like a SAN. If you wish to expose the same volume to multiple instances, you will have to use an NFS or SAMBA share from an existing instance.

            -
            -
            -

            Local Storage

            -

            Every instance larger than m1.tiny starts with some local storage (up to 160GB for m1.xlarge). This storage is currently the second partition on the root drive.

            -
            -
            -
            -

            Concept: Quotas

            -

            Nova supports per-project quotas. There are currently quotas for number of instances, total number of cores, number of volumes, total number of gigabytes, and number of floating ips.

            -
            -
            -

            Concept: RBAC

            -

            Nova provides roles based access control (RBAC) for access to api commands. A user can have a number of different roles. Roles define which api_commands a user can perform.

            -

            It is important to know that there are user-specific (sometimes called global) roles and project-specific roles. A user’s actual permissions in a particular project are the INTERSECTION of his user-specific roles and is project-specific roles.

            -

            For example: A user can access api commands allowed to the netadmin role (like allocate_address) only if he has the user-specific netadmin role AND the project-specific netadmin role.

            -

            More information about RBAC can be found in the Authentication and Authorization.

            -

            Concept: API

            -
              -
            • EC2
              • -
            • OpenStack / Rackspace
              • -
            -
            -
            -

            Concept: Networking

            -

            Nova has a concept of Fixed Ips and Floating ips. Fixed ips are assigned to an instance on creation and stay the same until the instance is explicitly terminated. Floating ips are ip addresses that can be dynamically associated with an instance. This address can be disassociated and associated with another instance at any time.

            -

            There are multiple strategies available for implementing fixed ips:

            -
            -

            Flat Mode

            -

            The simplest networking mode. Each instance receives a fixed ip from the pool. All instances are attached to the same bridge (br100) by default. The bridge must be configured manually. The networking configuration is injected into the instance before it is booted. Note that this currently only works on linux-style systems that keep networking configuration in /etc/network/interfaces.

            -
            -
            -

            Flat DHCP Mode

            -

            This is similar to the flat mode, in that all instances are attached to the same bridge. In this mode nova does a bit more configuration, it will attempt to bridge into an ethernet device (eth0 by default). It will also run dnsmasq as a dhcpserver listening on this bridge. Instances receive their fixed ips by doing a dhcpdiscover.

            -
            -
            -

            VLAN DHCP Mode

            -

            This is the default networking mode and supports the most features. For multiple machine installation, it requires a switch that supports host-managed vlan tagging. In this mode, nova will create a vlan and bridge for each project. The project gets a range of private ips that are only accessible from inside the vlan. In order for a user to access the instances in their project, a special vpn instance (code named cloudpipe) needs to be created. Nova generates a certificate and key for the user to access the vpn and starts the vpn automatically. More information on cloudpipe can be found here.

            Concept: Binaries

            -

            Nova is implemented by a number of related binaries. These binaries can run on the same machine or many machines. A detailed description of each binary is given in the binaries section of the developer guide.

            Concept: nova-manage

            -

            The nova-manage command is used to perform many essential functions for -administration and ongoing maintenance of nova, such as user creation, -vpn management, and much more.

            -

            See doc:nova.manage in the Administration Guide for more details.

            Concept: IPC/RPC

            -

            Nova utilizes the RabbitMQ implementation of the AMQP messaging standard for performing communication between the various nova services. This message queuing service is used for both local and remote communication because Nova is designed so that there is no requirement that any of the services exist on the same physical machine. RabbitMQ in particular is very robust and provides the efficiency and reliability that Nova needs. More information about RabbitMQ can be found at http://www.rabbitmq.com/.

            Getting the Code

            -

            Nova is hosted on launchpad. You can get the code with the following command

            -
            bzr clone lp:nova
            -
            -

            The contrib/nova.sh file in the source distribution is a script that -will quickly set up nova to run on a single machine. It is tested against -Ubuntu only, but other distributions are forthcoming.

            -
            -
            -

            Environment Variables

            -

            By tweaking the environment that nova.sh run in, you can build slightly -different configurations (though for more complex setups you should see -Getting Started with Nova and Installing Nova on Multiple Servers).

            -
              -
            • -
              HOST_IP
              -
                -
              • Default: address of first interface from the ifconfig command
                • -
              • Values: 127.0.0.1, or any other valid address
                • -
              -
              -
              -
              • -
            -
            -

            TEST

            -

            Default: 0 -Values: 1, run tests after checkout and initial setup

            -
            -
            -

            USE_MYSQL

            -

            Default: 0, use sqlite3 -Values: 1, use mysql instead of sqlite3

            -
            -
            -

            MYSQL_PASS

            -

            Only useful if $USE_MYSQL=1.

            -

            Default: nova -Values: value of root password for mysql

            -
            -
            -

            USE_LDAP

            -

            Default: 0, use nova.auth.dbdriver -Values: 1, use nova.auth.ldapdriver

            -
            -
            -

            LIBVIRT_TYPE

            -

            Default: qemu -Values: uml, kvm

            -
            -
            -
            -

            Usage

            -

            Unless you want to spend a lot of time fiddling with permissions and sudoers, -you should probably run nova as root.

            -
            sudo -i
-
            -
            -

            If you are concerned about security, nova runs just fine inside a virtual -machine.

            -

            Use the script to install and run the current trunk. You can also specify a -specific branch by putting lp:~someone/nova/some-branch after the branch -command

            -
            ./nova.sh branch
-./nova.sh install
-./nova.sh run
            -
            -

            The run command will drop you into a screen session with all of the workers -running in different windows You can use eucatools to run commands against the -cloud.

            -
            euca-add-keypair test > test.pem
-euca-run-instances -k test -t m1.tiny ami-tiny
-euca-describe-instances
            -
            -

            To see output from the various workers, switch screen windows

            -
            <ctrl-a> "
            -
            -

            will give you a list of running windows.

            -

            When the instance is running, you should be able to ssh to it.

            -
            chmod 600 test.pem
-ssh -i test.pem root@10.0.0.3
            -
            -

            When you exit screen

            -
            <ctrl-a> <ctrl-d>
            -
            -

            nova will terminate. It may take a while for nova to finish cleaning up. If -you exit the process before it is done because there were some problems in your -build, you may have to clean up the nova processes manually. If you had any -instances running, you can attempt to kill them through the api:

            -
            ./nova.sh terminate
            -
            -

            Then you can destroy the screen:

            -
            ./nova.sh clean
            -
            -

            If things get particularly messed up, you might need to do some more intense -cleanup. Be careful, the following command will manually destroy all runnning -virsh instances and attempt to delete all vlans and bridges.

            -
            ./nova.sh scrub
            -
            -

            You can edit files in the install directory or do a bzr pull to pick up new versions. You only need to do

            -
            ./nova.sh run
            -
            -

            to run nova after the first install. The database should be cleaned up on each run.

            API Server

            -

            At the heart of the cloud framework is an API Server. This API Server makes command and control of the hypervisor, storage, and networking programmatically available to users in realization of the definition of cloud computing.

            -

            The API endpoints are basic http web services which handle authentication, authorization, and basic command and control functions using various API interfaces under the Amazon, Rackspace, and related models. This enables API compatibility with multiple existing tool sets created for interaction with offerings from other vendors. This broad compatibility prevents vendor lock-in.

            Message Queue

            -

            A messaging queue brokers the interaction between compute nodes (processing), volumes (block storage), the networking controllers (software which controls network infrastructure), API endpoints, the scheduler (determines which physical hardware to allocate to a virtual resource), and similar components. Communication to and from the cloud controller is by HTTP requests through multiple API endpoints.

            -

            A typical message passing event begins with the API server receiving a request from a user. The API server authenticates the user and ensures that the user is permitted to issue the subject command. Availability of objects implicated in the request is evaluated and, if available, the request is routed to the queuing engine for the relevant workers. Workers continually listen to the queue based on their role, and occasionally their type hostname. When such listening produces a work request, the worker takes assignment of the task and begins its execution. Upon completion, a response is dispatched to the queue which is received by the API server and relayed to the originating user. Database entries are queried, added, or removed as necessary throughout the process.

            Compute Worker

            -

            Compute workers manage computing instances on host machines. Through the API, commands are dispatched to compute workers to:

            -
              -
            • Run instances
              • -
            • Terminate instances
              • -
            • Reboot instances
              • -
            • Attach volumes
              • -
            • Detach volumes
              • -
            • Get console output
              • -
            -
            -
            -

            Network Controller

            -

            The Network Controller manages the networking resources on host machines. The API server dispatches commands through the message queue, which are subsequently processed by Network Controllers. Specific operations include:

            -
              -
            • Allocate Fixed IP Addresses
              • -
            • Configuring VLANs for projects
              • -
            • Configuring networks for compute nodes
              • -
            -
            -
            -

            Volume Workers

            -

            Volume Workers interact with iSCSI storage to manage LVM-based instance volumes. Specific functions include:

            -
              -
            • Create Volumes
              • -
            • Delete Volumes
              • -
            • Establish Compute volumes
              • -
            -

            Volumes may easily be transferred between instances, but may be attached to only a single instance at a time.

The architectu Nova implements RPC (both request+response, and one-way, respectively nicknamed 'rpc.call' and 'rpc.cast') over AMQP by providing an adapter class which take cares of marshalling and unmarshalling of messages into function calls. Each Nova service (for example Compute, Volume, etc.) create two queues at the initialization time, one which accepts messages with routing keys 'NODE-TYPE.NODE-ID' (for example compute.hostname) and another, which accepts messages with routing keys as generic 'NODE-TYPE' (for example compute). The former is used specifically when Nova-API needs to redirect commands to a specific node like 'euca-terminate instance'. In this case, only the compute node whose host's hypervisor is running the virtual machine can kill the instance. The API acts as a consumer when RPC calls are request/response, otherwise is acts as publisher only. Nova RPC Mappings -================= +----------------- The figure below shows the internals of a RabbitMQ node when a single instance is deployed and shared in an OpenStack cloud. Every Nova component connects to the RabbitMQ instance and, depending on its personality (for example a compute node or a network node), may use the queue either as an Invoker (such as API or Scheduler) or a Worker (such as Compute, Volume or Network). Invokers and Workers do not actually exist in the Nova object model, but we are going to use them as an abstraction for sake of clarity. An Invoker is a component that sends messages in the queuing system via two operations: 1) rpc.call and ii) rpc.cast; a Worker is a component that receives messages from the queuing system and reply accordingly to rcp.call operations. @@ -52,7 +52,7 @@ Figure 2 shows the following internal elements: ..
