[libvirt] [PATCH 0/2] btrfs subvolume management
by Oskari Saarenmaa 10 Oct '13

10 Oct '13

Moved btrfs subvolume management to storage_backend_fs.c instead of implementing it as a separate pool as suggested by Daniel P. Berrange in https://www.redhat.com/archives/libvir-list/2013-September/msg00316.html Oskari Saarenmaa (2): virFileFsType: get filesystem type of a given path storage: btrfs subvolumes for directory pools configure.ac | 25 ++- docs/schemas/storagevol.rng | 1 + docs/storage.html.in | 30 ++- libvirt.spec.in | 4 + src/conf/storage_conf.c | 3 + src/conf/storage_conf.h | 1 + src/libvirt_private.syms | 1 + src/storage/storage_backend.c | 15 +- src/storage/storage_backend_fs.c | 222 ++++++++++++++++++++-- src/util/virfile.c | 47 +++++ src/util/virfile.h | 1 + src/util/virstoragefile.c | 4 +- src/util/virstoragefile.h | 1 + tests/storagevolxml2xmlin/vol-btrfs-snapshot.xml | 13 ++ tests/storagevolxml2xmlin/vol-btrfs.xml | 9 + tests/storagevolxml2xmlout/vol-btrfs-snapshot.xml | 26 +++ tests/storagevolxml2xmlout/vol-btrfs.xml | 17 ++ tests/storagevolxml2xmltest.c | 2 + 18 files changed, 392 insertions(+), 30 deletions(-)

[libvirt] [PATCH] AArch64: Porting of armv7l conditons to run qemu for aarch64.
by Pranavkumar Sawargaonkar 10 Oct '13

10 Oct '13

AArch64 qemu has similar behavior as armv7l, like use of mmio etc. This patch adds similar bypass checks what we have for armv7l to aarch64. E.g. we are enabling mmio transport for Nicdev.

[libvirt] [PATCH] qemu: Init @pcidevs in qemuPrepareHostdevPCIDevices
by Michal Privoznik 10 Oct '13

10 Oct '13

At the beginning of the function qemuPrepareHostdevPCICheckSupport() is called. After that @pcidevs is initialized. However, if the very first command fails, we go to 'cleanup' label where virObjectUnref(pcidevs) is called. Obviously, it is called before @pcidevs was able to get initialized. Compiler warns about it: CC qemu/libvirt_driver_qemu_impl_la-qemu_hostdev.lo qemu/qemu_hostdev.c: In function 'qemuPrepareHostdevPCIDevices': qemu/qemu_hostdev.c:824:19: error: 'pcidevs' may be used uninitialized in this function [-Werror=maybe-uninitialized] virObjectUnref(pcidevs); ^ cc1: all warnings being treated as errors Signed-off-by: Michal Privoznik <mprivozn(a)redhat.com> --- Pushed under buildbreaker and trivial rules. src/qemu/qemu_hostdev.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/src/qemu/qemu_hostdev.c b/src/qemu/qemu_hostdev.c index 81e0e88..43c03cc 100644 --- a/src/qemu/qemu_hostdev.c +++ b/src/qemu/qemu_hostdev.c @@ -633,7 +633,7 @@ qemuPrepareHostdevPCIDevices(virQEMUDriverPtr driver, int nhostdevs, virQEMUCapsPtr qemuCaps) { - virPCIDeviceListPtr pcidevs; + virPCIDeviceListPtr pcidevs = NULL; int last_processed_hostdev_vf = -1; size_t i; int ret = -1; -- 1.8.1.5

[libvirt] Can we make sc_copyright_check non-fatal?
by Cole Robinson 10 Oct '13

10 Oct '13

The copyright date syntax check is a source of frustration for me: - It fails on old maint branches. - It pokes into non git managed directories in $(srcdir). I like to keep directories like f18-maint.git, f19-maint.git etc. that are checkouts of the respective maint branches so I can parallelize when doing maint builds, and I like to keep them in my libvirt.git dir for organization, but running syntax-check in libvirt.git fails on the copyright check in $(srcdir)/f18-maint.git/.gnulib/... Is there any way to make it non-fatal? If it still spams with all the 'failures' I'm sure that's enough to encourage fixing the issues without blocking valid usage. Thanks, Cole

[libvirt] [PATCH] qemu_migration: Check ABI stability against MIGRATABLE xml
by Michal Privoznik 10 Oct '13

10 Oct '13

https://bugzilla.redhat.com/show_bug.cgi?id=994364 If user provides domain XML in migration we check if it doesn't break ABI via virDomainDefCheckABIStability(). However, if the provided XML was generated via virDomainGetXMLDesc(..., VIR_DOMAIN_XML_MIGRATABLE) it is missing some devices, e.g. 'pci-root' controller. Hence, the ABI stability check fails even though it is stable.
