The new name "libvirt-daemon-plugin-sanlock" provides consistency with the
newly introduced "libvirt-daemon-plugin-lockd" subpackage.
It's also a good opportunity to taking ownership of
%{_libdir}/libvirt/lock-driver/, removing the need for a dependency on the
libvirt-daemon package.

Commit 379c0ce4bf introduced a call to umount(/dev) performed
inside the namespace that we run QEMU in.
As a result of this, on machines using AppArmor, VM startup now
fails with
internal error: Process exited prior to exec: libvirt:
QEMU Driver error: failed to umount devfs on /dev: Permission denied
The corresponding denial is
AVC apparmor="DENIED" operation="umount" profile="libvirtd"

Extend the AppArmor configuration for virtqemud and libvirtd so
that this operation is allowed.

This check is done when VM is defined but doesn't take into account what

To make proper check at this point we would have to figure out cgroups

net-user-passt.args was generated early during testing of the passt
qemu commandline, when qemuxml2argvtest was using
DO_TEST("net-user-passt"). This was later changed to
DO_TEST_CAPS_LATEST(), so the file net-user-passt.x86_64-latest.args
is used instead, but the original (now unused) test file was

This attribute was added to support setting the --interface option for

that it would be better to use the existing <source dev='xxx'/>

the wrong place). So we remove backend/upstream, and change the passt
commandline creation to grab the name for --interface from source/dev.

Currently, the ThreadContext object is generated whenever we see
.host-nodes attribute for a memory-backend-* object. The idea was
that when the backend is pinned to a specific set of host NUMA
nodes, then the allocation could be happening on CPUs from those
nodes too. But this may not be always possible.
Users might configure their guests in such way that vCPUs and
corresponding guest NUMA nodes are on different host NUMA nodes
than emulator thread. In this case, ThreadContext won't work,
because ThreadContext objects live in context of the emulator
thread (vCPU threads are moved around by us later, when emulator
thread finished its setup and spawned vCPU threads - see
qemuProcessSetupVcpus()). Therefore, memory allocation is done by
emulator thread which is pinned to a subset of host NUMA nodes,
but tries to create a ThreadContext object with a disjoint subset
of host NUMA nodes, which fails.

The default expiry time is 30 days. Since the RPM artifacts coming from
the previous pipeline stages are set to expire in 1 day we can set the
failed integration job log artifacts to the same value. The sentiment
here is that if an integration job legitimately failed (i.e. not with
an infrastructure failure) unless it was fixed in the meantime it will
fail the next day with the scheduled pipeline again, meaning, that even
if the older log artifacts are removed, they'll be immediately
replaced with fresh ones.

The remote_*_args methods will generally borrow pointers
passed in the caller, so should not be freed.
On failure of the virTypedParamsSerialize method, however,
xdr_free was being called. This is presumably because it
was thought that the params may have been partially
serialized and need cleaning up. This is incorrect, as
virTypedParamsSerialize takes care to cleanup partially
serialized data. This xdr_free call would lead to free'ing
the borrowed cookie pointers, which would be a double free.

The only reason we need it at build time is to find its location in
$PATH so it can be hardcoded into the libvirt binary (and avoid the
possibility of someone adding in a malicious binary somewhere earlier
in the path, I guess).
Only 'recommend' passt during installation though, since it is not
needed unless someone is actually using it.
There is no need to add in a build-time "WITH_PASST" option (IMO),
since it adds very little to the size of the code - "PASST" (the path
to the binary) will just be set to "passt", so if someone does manage
to build and install passt on an older version of Fedora or RHEL, it
will still work (as long as it's installed somewhere in the path).
