The directory name changed in a89f05ba.

This unbreaks launching QEMU/KVM VMs with apparmor enabled. It also adds
the directory for the qemu guest-agent socket which is not known when
parsing the domain XML.

This reverts commit ee4cfb56.

Since we're still not persisting our bookkeeping lists across
daemon restarts, we might have lost some information
virPCIDeviceReattach() relies on, for example whether the
device needs to be unbound from the stub driver.

As a result, if the daemon has been restarted in the meantime,
the device might end up remaining bound to the stub driver even
after 'virsh nodedev-reattach' or similar has been called, with
no way of giving it back to the host short of messing with
sysfs behind libvirt's back.

Revert back to the previous behavior of always trying to bind
the device to the host driver, regardless of its status when it
was detached, until persistent bookkeeping lists have been
implemented.

According to MDN[1], 'margin-left' and similar CSS properties,
including 'margin-right', cannot be applied to the '::first-line'
pseudo-element, so this rule will never have any effect and can
be safely removed.

Commit e14c5069 dropped the only user of the 'sponsor'
CSS id, so we can drop it from the stylesheet as well.

When using the --start option, the show_count should not be set to
max_id as the --start <cpu> means we dont need those many initial cpu
stats. Hence, show_count should be adjusted accordingly.

Commit 08cc14f7 moved the conversion of MiB/s to B/s out of the

caller.

This patch will convert the migrate_speed value from MiB/s to its

Chunyan sent a nice cleanup patch for libxlDomainDetachNetDevice

https://www.redhat.com/archives/libvir-list/2016-March/msg00926.html

which I incorrectly modified before pushing as commit b5534e53. My
modification caused network devices of type hostdev to no longer
be removed. This patch changes b5534e53 to resemble Chunyan's
original, correct patch.

Chunyan sent a correct patch to fix a resource leak on error in
libxlDomainAttachNetDevice

I made what was thought to be an improvement and pushed the patch as
commit e6336442. As it turns out, my change broke adding net devices
that are actually hostdevs to the list of nets in virDomainDef. This

We use _LAST items in enums to mark the last position in given
enum. Now, if and enum is passed to switch(), compiler checks
that all the values from enum occur in 'case' enumeration.
Including _LAST. But coverity spots it's a dead code. And it
really is. So to resolve this, we tend to put a comment just
above 'case ..._LAST' notifying coverity that we know this is a
dead code but we want to have it that way.

All headers except for <h1> were already bold: make it bold as

Now that we have @flags we can support changing perf events just
in active or inactive configuration regardless of the other.
Previously, calling virDomainSetPerfEvents set events in both
active and inactive configuration at once. Even though we allow
users to set perf events that are to be enabled once domain is
started up. The virDomainGetPerfEvents API was flawed too. It
returned just runtime info.

They recently were extracted to a separate function. They don't belong
together though. Since -numa formatting is pretty compact, move it to
the main function and rename qemuBuildNumaCommandLine to
qemuBuildMemoryDeviceCommandLine.

When starting up a VM libvirtd asks numad to place the VM in case of
automatic nodeset. The nodeset would not be passed to the memory device
formatter and the user would get an error.

If the cpu cgroup is not found when validating an host for

The appropriate option is really CONFIG_CGROUP_CPU. The

Remove disabling domain death events from libxlDomainStart error
path. The domain death event is already disabled in libxlDomainCleanup.
Signed-off-by: NJim Fehlig <jfehlig@suse.com>

libxlDomainStart allocates and reserves resources that were not
being released in error paths. libxlDomainCleanup already handles
the job of releasing resources, and libxlDomainStart should call
it when encountering a failure.

Change the error handling logic to call libxlDomainCleanup on
failure. This includes acquiring the lease sooner and allowing
it to be released in libxlDomainCleanup on failure, similar to
the way other resources are reclaimed. With the lease now
released in libxlDomainCleanup, the release_dom label can be
renamed to cleanup_dom to better reflect its changed semantics.

Create a bitmap of iothreads that have scheduler info set so that the
transformation algorithm does not have to iterate the empty bitmap many
times. By reusing self-expanding bitmaps the bitmap size does not need
to be pre-calculated.

Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1264008

In some cases it's impractical to use the regular APIs as the bitmap
size needs to be pre-declared. These new APIs allow to use bitmaps that
self expand.

The new code adds a property to the bitmap to track the allocation of
memory so that VIR_RESIZE_N can be used.

 * Sync stubbed functions with prototypes
 * Add missing ATTRIBUTE_UNUSED where needed
