Fix all thread locking bugs reported by object-locking test
case.
NB, some of the driver locking is getting too coarse. Driver
mutexes really need to be turned into RW locks instead to
significantly increase concurrency.
* src/lxc_driver.c: Fix useof driver when unlocked in the methods
lxcDomainGetInfo, lxcSetSchedulerParameters, and
lxcGetSchedulerParameters
* src/opennebula/one_driver.c: Fix missing unlock in oneDomainUndefine.
Fix use of driver when unlocked in oneDomainGetInfo,
oneGetOSType, oneDomainShutdown
* src/qemu_driver.c: Fix use of driver when unlocked in
qemudDomainSavem, qemuGetSchedulerType, qemuSetSchedulerParameters
and qemuGetSchedulerParameters
* src/storage_driver.c: Re-work storagePoolCreate to avoid bogus
lock checking warning. Re-work storageVolumeCreateXMLFrom to
remove a potential NULL de-reference & avoid bogus lock check
warnings
* src/test.c: Remove testDomainAssignDef since it break lock chekc
warnings.
* tests/object-locking.ml: Add oneDriverLock, oneDriverUnlock
and one_driver_t methods/types to allow lock checking on the
OpenNebula drivers
* tests/testutilsqemu.c: add a machine types list for /usr/bin/kvm
which doesn't have any aliases, while the guest has aliases
* tests/qemuxml2argvdata/qemuxml2argv-machine-aliases2.*,
tests/qemuxml2argvtest.c: add a test using /usr/bin/kvm and make
sure that 'pc' machine type doesn't get canonicalized using the
aliases in the guest machine type list
The algorithm is quite simple:
If the emulator matches a guest's domain:
if domain has machine type info:
check the domain's machine type info
else
check the guest's default machine type info
else if the emulator matches the guest's default emulator:
check the guest's default machine type info
The previous implementation was incorrectly falling back to the default
machine type info if the domain's machine type info didn't have an
alias.
* src/qemu_driver.c: simplify and fix qemudCanonicalizeMachine()
Currently we only probe the main qemu binary for machine types, but we
should also probe the kvm binary.
* src/qemu_conf.c: probe kvm binary machines in qemudCapsInitGuest()
We need to look at all the domain infos in guest capabilities, not
just the defaults.
In order to allow that, split out a qemudGetOldMachinesFromInfo()
from qemudGetOldMachines(). We'll make more use of it in the next
patch.
* src/qemu_conf.c: split out qemudGetOldMachinesFromInfo() from
qemudGetOldMachines()
* tests/testutilsqemu.c: make 'pc' an alias for qemu-system-x86_64
* tests/qemuxml2argvdata/qemuxml2argv-machine-aliases1.*,
tests/qemuxml2argvtest.c: add a test which uses qemu-system-x86_64
and make sure the machine type is canonicalized.
This doesn't have any affect on the current tests because we don't have
any machine aliases in the current test data.
* src/qemu_conf.h, src/qemu_driver.c: expose qemudCanonicalizeMachine()
for the tests
* tests/qemuxml2argvtest.c: canonicalize the machine type
Things added include
- x86_64 host
- Migration features
- NUMA topology
- Security model
- Canonical machine types
- Domain machine types
- An arm guest
- More machine types for mips, mipsel, sparc and ppc
- An x86_64 xenner guest
This file was generated on a Fedora 12 machine using latest libvirt
and qemu-kvm-0.11.0-rc2
* tests/capabilityschemadata/caps-qemu-kvm.xml: add more features
to test
After the mentioned patch was applied, I noticed that
shutting down a kvm guest from inside (i.e. poweroff) caused
the guest to shutdown, but not removed from the list of
active guests. DanB pointed out that the problem is that
the virEventAddHandle() call in the qemu driver was asking
to watch for 0 events, not HANGUP | ERROR as it should. Add
these events so that shutdown works again.

lzop was removed due to some confusion over whether it provided functional
advantages distinct from xz. This has been addressed in the mailing list post
archived at http://permalink.gmane.org/gmane.comp.emulators.libvirt/16487, and
support for lzop is re-added here.
* libvirt.spec.in: add dependancy on lzop
* src/qemu.conf: update documentation of save_image_format
* src/qemu_driver.c: re-add lzop compression option
* src/qemu_driver.c: drop lzma and lzop images compression options
as they are deprecated by xz
* libvirt.spec.in: add requires for xz/bzip2/gzip as they are needed
to implement the compression options
* configure.in: phyp driver uses libssh2_session_block_directions()
which is only available in libssh2 >= 1.0, so check for this symbol
too when configuring
* src/qemu_driver.c (QEMUD_SAVE_FORMAT_LAST): Define.
(qemudSaveCompressionTypeFromString): Declare.
(qemudSaveCompressionTypeToString): Declare.
(qemudDomainSave): Use those functions rather than open-coding them.
Use "cat >> '%s' ..." in place of equivalent
"dd of='%s' oflag=append conv=notrunc ...".
* src/qemu_driver.c (enum qemud_save_formats) [QEMUD_SAVE_FORMAT_XZ]:
New member.
[QEMUD_SAVE_FORMAT_LZMA]: Mark as deprecated.
Use an explicit value for each member.
(qemudDomainSave, qemudDomainRestore): Handle the new member.
* src/qemu.conf: Mention xz, too.
* configure.in src/Makefile.am src/storage_backend.[ch]
src/storage_conf.[ch] src/storage_backend_mpath.[ch] po/POTFILES.in:
add a new module for storage multipath, it requires device-mapper
* src/xm_internal.c (xenXMDomainConfigParse): After t=strchr...
don't test *t; it's known. This was *not* detected by clang,
but I spotted it since once instance was in the vicinity of the
dead increment of "data".
* src/vbox/vbox_tmpl.c: minor bug in selecting the graphics type. if the
graphics type was desktop it was assumed that display is set for it,
and thus crashed on strdup. Also adds a number of missing OOM checks.
* src/lxc_container.c (lxcContainerMountBasicFS): Don't leak upon failure.
Add "cleanup:" label and change each post-allocation failure to
use "goto cleanup" rather than returning immediately.
