This patch updates libvirt's API to allow applications to inspect the full list of security labels of a domain. Signed-off-by: Marcelo Cerri <mhcerri@linux.vnet.ibm.com>
Commit 6ed5a1b9bd6240b8f2736790e48dd1c284c2e0e1 adds close callback functions to the public API but doesn't add python implementation. This patch sets the function to be written manually (to fix the build), but doesn't implement them yet.
When the guest changes its memory balloon applications may want to know what the new value is, without having to periodically poll on XML / domain info. Introduce a "balloon change" event to let apps see this * include/libvirt/libvirt.h.in: Define the virConnectDomainEventBalloonChangeCallback callback and VIR_DOMAIN_EVENT_ID_BALLOON_CHANGE constant * python/libvirt-override-virConnect.py, python/libvirt-override.c: Wire up helpers for new event * daemon/remote.c: Helper for serializing balloon event * examples/domain-events/events-c/event-test.c, examples/domain-events/events-python/event-test.py: Add example of balloon event usage * src/conf/domain_event.c, src/conf/domain_event.h: Handling of balloon events * src/remote/remote_driver.c: Add handler of balloon events * src/remote/remote_protocol.x: Define wire protocol for balloon events * src/remote_protocol-structs: Likewise.

This adds support for the new virDomainListAllSnapshots (a domain function) and virDomainSnapshotListAllChildren (a snapshot function) to the libvirt-python bindings. The implementation is done manually as the generator does not support wrapping lists of C pointers into python objects. * python/libvirt-override.c (libvirt_virDomainListAllSnapshots) (libvirt_virDomainSnapshotListAllChildren): New functions. * python/libvirt-override-api.xml: Document them. * python/libvirt-override-virDomain.py (listAllSnapshots): New file. * python/libvirt-override-virDomainSnapshot.py (listAllChildren): Likewise. * python/Makefile.am (CLASSES_EXTRA): Ship them.
There was an inherent race between virDomainSnapshotNum() and virDomainSnapshotListNames(), where an additional snapshot could be created in the meantime, or where a snapshot could be deleted before converting the name back to a virDomainSnapshotPtr. It was also an awkward name: the function operates on domains, not domain snapshots. virDomainSnapshotListChildrenNames() suffered from the same inherent race, although its naming was nicer. This patch makes things nicer by grabbing a snapshot list atomically, in the format most useful to the user. * include/libvirt/libvirt.h.in (virDomainListAllSnapshots) (virDomainSnapshotListAllChildren): New declarations. * src/libvirt.c (virDomainSnapshotListNames) (virDomainSnapshotListChildrenNames): Add cross-references. (virDomainListAllSnapshots, virDomainSnapshotListAllChildren): New functions. * src/libvirt_public.syms (LIBVIRT_0.9.13): Export them. * src/driver.h (virDrvDomainListAllSnapshots) (virDrvDomainSnapshotListAllChildren): New callbacks. * python/generator.py (skip_function): Prepare for later hand-written versions.
This patch adds export of the new API function virConnectListAllDomains() to the libvirt-python bindings. The virConnect object now has method "listAllDomains" that takes only the flags parameter and returns a python list of virDomain object corresponding to virDomainPtrs returned by the underlying api. The implementation is done manually as the generator does not support wrapping list of virDomainPtrs into virDomain objects.
This patch adds a new public api that lists domains. The new approach is
different from those used before. There are key points to this:
1) The list is acquired atomically and contains both active and inactive
domains (guests). This eliminates the need to call two different list
APIs, where the state might change in between the calls.
2) The returned list consists of virDomainPtrs instead of names or ID's
that have to be converted to virDomainPtrs anyways using separate calls
for each one of them. This is more convenient and saves hypervisor calls.
3) The returned list is auto-allocated. This saves a lot of hassle for
the users.
4) Built in support for filtering. The API call supports various
filtering flags that modify the output list according to user needs.
Available filter groups:
Domain status:
VIR_CONNECT_LIST_DOMAINS_ACTIVE, VIR_CONNECT_LIST_DOMAINS_INACTIVE
Domain persistence:
VIR_CONNECT_LIST_DOMAINS_PERSISTENT,
VIR_CONNECT_LIST_DOMAINS_TRANSIENT
Domain state:
VIR_CONNECT_LIST_DOMAINS_RUNNING, VIR_CONNECT_LIST_DOMAINS_PAUSED,
VIR_CONNECT_LIST_DOMAINS_SHUTOFF, VIR_CONNECT_LIST_DOMAINS_OTHER
Existence of managed save image:
VIR_CONNECT_LIST_DOMAINS_MANAGEDSAVE,
VIR_CONNECT_LIST_DOMAINS_NO_MANAGEDSAVE
Auto-start option:
VIR_CONNECT_LIST_DOMAINS_AUTOSTART,
VIR_CONNECT_LIST_DOMAINS_NO_AUTOSTART
Existence of snapshot:
VIR_CONNECT_LIST_DOMAINS_HAS_SNAPSHOT,
VIR_CONNECT_LIST_DOMAINS_NO_SNAPSHOT
5) The python binding returns a list of domain objects that is very neat
to work with.
The only problem with this approach is no support from code generators
so both RPC code and python bindings had to be written manually.
*include/libvirt/libvirt.h.in: - add API prototype
- clean up whitespace mistakes nearby
*python/generator.py: - inhibit generation of the bindings for the new
api
*src/driver.h: - add driver prototype
- clean up some whitespace mistakes nearby
*src/libvirt.c: - add public implementation
*src/libvirt_public.syms: - export the new symbol
Python exceptions are different than libvirt errors, and we had some corner case bugs on OOM situations. * python/libvirt-override.c (libvirt_virDomainSnapshotListNames) (libvirt_virDomainSnapshotListChildrenNames): Use correct error returns, avoid segv on OOM, and avoid memory leaks on error.
