* Use virtio-serial, remove other vmchannel methods.Richard Jones2010-08-244-410/+63
| | | | | | | | | | | | | This adds support for virtio-serial, and removes all other vmchannel methods. Virtio-serial is faster than other methods, and is now widely available. I tested this by using the guestfs_upload API on an 83 MB file: before: 6.12 seconds (14.1 MB/sec) after: 4.20 seconds (20.6 MB/sec) (note this is with the current 8K chunk size)
* Change to using ext2-based, cached supermin appliance.Richard Jones2010-08-2310-191/+529
| | | | | | | | | | | | This changes the method used to build the supermin appliance to use the new ext2-based appliance supported by latest febootstrap. The appliance can also be cached, so we avoid rebuilding it each time it is used. Mailing list discussion goes into the rationale and details: https://www.redhat.com/archives/libguestfs/2010-August/msg00028.html Requires febootstrap >= 2.8.

* Remove old ocaml-inspector code.Richard Jones2010-08-173-542/+3
| | | | | Not used by anyone, didn't work well, and replaced now by the C inspection APIs.
* fish: Reimplement -i option using new C-based inspection.Richard Jones2010-08-176-137/+187
| | | | | | | | | | | | | | Don't shell out to virt-inspector. Instead, use the new C-based inspection APIs. This is much faster. The new syntax is slightly different: guestfish -a disk.img -i guestfish -d guest -i However, the old syntax still works.
* fish: Add -c/--connect and -d/--domain options.Richard Jones2010-08-178-33/+326
| | | | | | | | The -d option lets you specify libvirt domains. The disks from these domains are found and added, as if you'd named them with -a. The -c option lets you specify a libvirt URI, which is needed when we consult libvirt to implement the above.
* New APIs for guest inspection.Richard Jones2010-08-176-5/+1360
| | | | | | | | | | | | | | | | | | | | | This commit converts (some of) the Perl inspection code to C and makes it available through core APIs. The new APIs are: inspect-os - Does the inspection, returns list of OSes inspect-get-* - Get results of the inspection where '*' is one of: type - 'windows' or 'linux' distro - Linux distro arch - architecture product-name - long product name string major-version minor-version - major.minor version of OS mountpoints - get a list of the mountpoints filesystems - get all filesystems associated with the OS This works for all existing supported Linux and Windows OSes.
* New APIs: findfs-label and findfs-uuidRichard Jones2010-08-175-3/+101
| | | | | | | | | | | | | | | | | | | | | | | | | These two calls wrap up the /sbin/findfs command, allowing you to find a filesystem by only knowing its label or UUID. This is especially useful when resolving LABEL=... or UUID=... entries in /etc/fstab. Sample guestfish session: ><fs> vfs-uuid /dev/vda1 277dd61c-bf34-4253-a8dc-df500a05e7df ><fs> findfs-uuid 277dd61c-bf34-4253-a8dc-df500a05e7df /dev/vda1 ><fs> vfs-label /dev/vda1 /boot ><fs> findfs-label /boot /dev/vda1 ><fs> vfs-uuid /dev/VolGroup00/LogVol00 40ce7c36-82ce-4a12-a99d-48f5e054162c ><fs> findfs-uuid 40ce7c36-82ce-4a12-a99d-48f5e054162c /dev/mapper/VolGroup00-LogVol00 ><fs> findfs-uuid 12345678 libguestfs: error: findfs_uuid: findfs: unable to resolve 'UUID=12345678'
* New API: file-architectureRichard Jones2010-08-178-215/+437
| | | | | | This change simply converts the existing Perl-only function file_architecture into a core API call. The core API call is written in C and available in all languages and from guestfish.
* generator: No need to redefine safe_* macros.Richard Jones2010-08-171-7/+0
| | | | | These are already defined in "guestfs-internal.h" which is included in the .c file.

* Send trace output to stderr.Matthew Booth2010-08-171-14/+14
| | | | | Trace output sent to stdout can be lost in the event of a crash due to buffering. This patch sends it to stderr instead.

* New API: is-lv: check if a block device is a logical volume (RHBZ#619793)Richard Jones2010-07-303-1/+58
| | | | | | | | | | | | | | | | | | | | | | | | | | This adds a new API, guestfs_is_lv (g, device), which returns true iff the named device is an LVM2 logical volume. A sample guestfish session: ><fs> lvs /dev/vg_f13x64/lv_root /dev/vg_f13x64/lv_swap ><fs> list-devices /dev/vda ><fs> list-partitions /dev/vda1 /dev/vda2 ><fs> is-lv /dev/vg_f13x64/lv_root true ><fs> is-lv /dev/vg_f13x64/lv_swap true ><fs> is-lv /dev/vda false ><fs> is-lv /dev/vda1 false ><fs> is-lv /dev/vda2 false
* Rename internal functions.Richard Jones2010-07-283-12/+12
| | | | | | | This is an update to commit 41f25ab3df5f306ac717fa7a6efd58328d30c1ae. Internal functions should be named guestfs___* (3 underscores) to avoid clashing with the implementation of actions (2 underscores).
* Rearrange library code into separate files.Richard Jones2010-07-276-2211/+2356
| | | | | | | | | | | | We split the library code into these separate files: - guestfs.c: creating handles, closing handles, handle-related variables - actions.c: generated library-side stubs for each action - bindtests.c: generated code to test bindings - launch.c: launching the appliance - proto.c: the library side of the daemon communications protocol This is just code movement.
* Rename guestfs-{actions,bindtests}.c to {actions,bindtests}.cRichard Jones2010-07-275-11/+11
| | | | | Rename these two generated files, in preparation for splitting up the main src/guestfs.c file.

* regressions: Don't print misleading 'Expect error ...' lines.Richard Jones2010-07-227-5/+27
| | | | | | | | | | | | | Some tests in the regressions directory deliberately print error messages. As long as they still PASS, this is OK. However these tests also printed some misleading messages about what error to expect. Since error messages were slightly different across distros, these messages were not accurate. Therefore remove these messages, and replace with a general message before all tests telling users not to worry about errors from the tests as long as the tests don't fail.
* New APIs: Support for creating LUKS and managing keys.Richard Jones2010-07-226-23/+311
| | | | | | | | | | | | | | | | | | | This commit adds four APIs for creating new LUKS devices and key management. These are: luks_format Format a LUKS device with the default cipher. luks_format_cipher Format with a chosen cipher. luks_add_key Add another key to an existing device. luks_kill_slot Delete a key from an existing device. This enables all the significant functionality of the cryptsetup luks* commands. Note that you can obtain the UUID of a LUKS device already by using vfs-uuid. This also includes a regression test covering all the LUKS functions.

* Revert "add_drive_ro adds readonly=on option if available." (RHBZ#617200).Richard Jones2010-07-222-21/+5
| | | | | | | | | | | | | | | | | | Adding the readonly=on option is not so clever. This causes qemu to present the disk as read-only to the guest. (The expected behaviour of snapshots=on,readonly=on was that it would open the disk O_RDONLY but present a writable disk to the guest). Since the guest sees a read-only disk, we are unable to do any recovery if a filesystem on the disk is inconsistent. This basically prevents most accesses to live disk images. What we really want is a qemu option which presents a writable disk to the guest, but only opens the disk on the host side with O_RDONLY, to alleviate the udev bug RHBZ#571714. This reverts commit 676462684e05dd8341dd695762dd99a87d8ec022.

* New APIs: Support for opening LUKS-encrypted disks.Richard Jones2010-07-2110-1/+272
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds support for opening LUKS-encrypted disks, via three new APIs: luks_open: Create a mapping for an encrypted disk. luks_open_ro: Same, but read-only mapping. luks_close: Close a mapping. A typical guestfish session using this functionality looks like this: $ guestfish --ro -a encrypted.img ><fs> run ><fs> list-devices /dev/vda ><fs> list-partitions /dev/vda1 /dev/vda2 ><fs> vfs-type /dev/vda2 crypto_LUKS ><fs> luks-open /dev/vda2 luksdev Enter key or passphrase ("key"): ><fs> vgscan ><fs> vg-activate-all true ><fs> pvs /dev/dm-0 ><fs> vgs vg_f13x64encrypted ><fs> lvs /dev/vg_f13x64encrypted/lv_root /dev/vg_f13x64encrypted/lv_swap ><fs> mount /dev/vg_f13x64encrypted/lv_root / ><fs> ll / total 132 dr-xr-xr-x. 24 root root 4096 Jul 21 12:01 . dr-xr-xr-x 20 root root 0 Jul 21 20:06 .. drwx------. 3 root root 4096 Jul 21 11:59 .dbus drwx------. 2 root root 4096 Jul 21 12:00 .pulse -rw-------. 1 root root 256 Jul 21 12:00 .pulse-cookie dr-xr-xr-x. 2 root root 4096 May 13 03:03 bin NOT included in this patch: - An easier way to use this from guestfish. - Ability to create LUKS devices. - Ability to change LUKS keys on existing devices. - Direct access to the /dev/mapper device (eg. if it contains anything apart from VGs).
* generator: Add 'Key' parameter type.Richard Jones2010-07-215-75/+215
| | | | | | | | | | | | | Add a 'Key' parameter type, used for passing sensitive key material into libguestfs. Eventually the plan is to mlock() key material into memory. However this is very difficult to achieve because the encoded XDR strings end up in many places. Therefore users should note that key material passed to libguestfs might end up in swap. The only difference between 'Key' and 'String' currently is that guestfish requests the key from /dev/tty with echoing turned off.
* generator: Remove unnecessary parameter.Richard Jones2010-07-211-4/+4
| | | | | The 'name' parameter is not used on the right hand side of the match, so it can be removed.
* df: Minimize the number of times we launch the libguestfs appliance.Richard Jones2010-07-161-40/+177
| | | | | | | | | | | | | | | This commit greatly improves the performance of the 'virt-df' command by batching as many disks as possible onto a single appliance. In many situations this means the appliance is launched only once, versus one launch per domain as before. However doing it this way is a lot more complex: (1) Because of limits in Linux and virtio-blk, we can only attach 26 disks maximum at a time to the appliance. (2) We have to use LVM filters (lvm-set-filter) to confine LVM to the disks of a single guest.
* New APIs: lvm-set-filter and lvm-clear-filter.Richard Jones2010-07-168-1/+382
| | | | | | | These APIs allow you to change the device filter, the list of block devices that LVM "sees". Either you can set it to a fixed list of devices / partitions, or you can clear it so that LVM sees everything.
* Use an unsigned type (size_t) for all loop iterators.Richard Jones2010-07-162-23/+27
| | | | | | | | | This resolves a warning from gcc 4.5: assuming signed overflow does not occur when simplifying conditional to constant This page explains the issues in some detail: http://www.airs.com/blog/archives/120
* generator: Don't hard-code name in DeviceList check.Richard Jones2010-07-161-3/+6
| | | | | Only one function currently uses DeviceList. The generated code unfortunately hard-coded the argument name from that function.
* build: Don't warn about 'long long'.Richard Jones2010-07-161-0/+2
| | | | | Various language bindings simply need this, so we have to allow it even though it's a GCC extension.

* Make tmp directory world readable (RHBZ#610880).Richard Jones2010-07-071-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | If you have a restrictive umask (0077 for example) then files in the tmp directory would be created with 0600 permissions. Example: drwx------. 2 rjones rjones 4096 Jul 2 17:52 . drwxrwxrwt. 57 root root 102400 Jul 2 17:52 .. -rw-------. 1 rjones rjones 86328832 Jul 2 17:52 initrd lrwxrwxrwx. 1 rjones rjones 46 Jul 2 17:52 kernel -> /boot/vmlinuz-2.6.33-0.40.rc7.git0.fc13.x86_64 This in itself is not a problem. However in virt-v2v we also change UID:GID and the result is that qemu is unable to read the initrd file: qemu: could not load initial ram disk '/tmp/libguestfs2ssynP/initrd' With this patch we make the tmp directory and the files world readable. After the patch: $ ls -la /tmp/libguestfsJFVzPg/ total 116192 drwxr-xr-x. 2 rjones rjones 4096 Jul 2 18:03 . drwxrwxrwt. 56 root root 102400 Jul 2 18:03 .. -rw-r--r--. 1 rjones rjones 118869504 Jul 2 18:03 initrd lrwxrwxrwx. 1 rjones rjones 46 Jul 2 18:03 kernel -> /boot/vmlinuz-2.6.33-0.40.rc7.git0.fc13.x86_64
* fish: Don't fail if -m and --listen flags are both given (RHBZ#612178).Richard Jones2010-07-071-0/+11
| | | | | | | | | | | | | Testing this against a Fedora disk image: $ ./fish/guestfish --ro -a F13.img -m /dev/sda1 --listen export GUESTFISH_PID=6033 $ ./fish/guestfish --remote=6033 -- ping-daemon $ ./fish/guestfish --remote=6033 -- ping-daemon $ ./fish/guestfish --remote=6033 -- exit Without this fix the first remote command would fail because qemu would have already been killed.
