[libvirt] [PATCH v2] virsh: Checking the volume capacity before uploading a new file.
by Julio Faracco 29 Jan '18

29 Jan '18

The current command 'vol-upload' is not checking if the volume accepts a file bigger than its capacity. It can cause an interrupt of the upload stream. This commit adds a check that fails before starting to send new file to volume if the file is bigger.

[libvirt] [PATCH] qemu: Fix memory leak in processGuestPanicEvent
by John Ferlan 28 Jan '18

28 Jan '18

After processing the processEvent->data for a qemuProcessEventHandler callout, it's expected that the called processEvent->eventType helper will perform the proper free on the data field. In this case it's a qemuMonitorEventPanicInfoPtr. Signed-off-by: John Ferlan <jferlan(a)redhat.com> --- Noticed this while working through the DumpComplete patch series. One has to follow the bouncing ball, but will note that when the processEvent->data is passed to other cases, it ends up getting VIR_FREE()'d at the end of various functions, so this should too since it's at the end of the line. src/qemu/qemu_driver.c | 1 + 1 file changed, 1 insertion(+) diff --git a/src/qemu/qemu_driver.c b/src/qemu/qemu_driver.c index a203c9297..5eaf97a46 100644 --- a/src/qemu/qemu_driver.c +++ b/src/qemu/qemu_driver.c @@ -4309,6 +4309,7 @@ processGuestPanicEvent(virQEMUDriverPtr driver, qemuDomainRemoveInactiveJob(driver, vm); cleanup: + qemuMonitorEventPanicInfoFree(info); virObjectUnref(cfg); } -- 2.13.6

[libvirt] [PATCH] tests: Clean up GIC test cases
by Andrea Bolognani 28 Jan '18

28 Jan '18

These test cases are supposed to verify GIC support works as expected, and shouldn't concern themselves with other features; we can trim them down significantly, and make them less likely to need updating after unrelated changes.

IIRC, we don't have any mechanism to actually prevent migration if an unmigratable flag is enabled. We just avoid enabling them by accident on "-cpu host". This case is slightly more problematic, however: the new feature is actually migratable (under very controlled circumstances) because of patch 2/2, but it is not migration-safe[1]. This means libvirt shouldn't include it in "host-model" expansion (which uses the query-cpu-model-expansion QMP command) until we make the feature migration-safe. For QEMU, this means the feature shouldn't be returned by "query-cpu-model-expansion type=static model=max" (but it can be returned by "query-cpu-model-expansion type=full model=max"). Jiri, it looks like libvirt uses type=full on query-cpu-model-expansion on x86. It needs to use type=static[2], or it will have no way to find out if a feature is migration-safe or not. This case is similar to "pmu", which is not migration-safe but enabled by -cpu host by default. But "pmu" is less problematic because it is already skipped by query-cpu-model-expansion type=static. --- [1] "migration-safe" is defined in the documentation for CpuDefinitionInfo on the QAPI schema: # @migration-safe: whether a CPU definition can be safely used for # migration in combination with a QEMU compatibility machine # when migrating between different QMU versions and between # hosts with different sets of (hardware or software) # capabilities. If not provided, information is not available # and callers should not assume the CPU definition to be # migration-safe. (since 2.8) [2] It looks like libvirt uses type=full because it wants to get all QOM property aliases returned. In this case, one solution for libvirt is to use: static_expansion = query_cpu_model_expansion(type=static, model) all_props = query_cpu_model_expansion(type=full, static_expansion) -- Eduardo

[libvirt] [PATCH] docs: Add missing element encryption description term entry

[libvirt] [PATCH hooks 0/1] Enforce requirement for Signed-off-by line
by Daniel P. Berrange 25 Jan '18

25 Jan '18

As a general rule most libvirt commits in recent history have have a valid Signed-off-by line present. There are still cases, however, where this is being forgotten. It is time to put some checks on git pushes to detect missinged Signed-off-by lines and reject the push. I created a new git repository that contains the original git repository update hook Eric provided years back. This commit then augments that hook to add the Signed-off-by check. The updated hook gets automatically installed on the server when we push to this repo. Daniel P.
