When a block job is terminated we should clear the 'mirrorState' and

Use the per-job state to determine when the non-shared-storage mirror is
complete rather than the per-disk definition one. The qemuBlockJobData
is a newer approach and is always cleared after the blockjob is
terminated while the 'mirrorState' variable in the definition of the
disk may be left over. In such case the disk mirror would be considered
complete prematurely.

So far we assumed that any vhostuser interface is plugged into an
OVS bridge and thus 'ovs-vsctl' exists. But this is not always
true. In testing scenarios it is possible to create a vhostuser
interface with this tool dpdk-testpmd (part of dpdk RPM) which
creates/connects to UNIX socket needed for vhostuser. Of course,
since there is no OVS then there is no interface name in which
case virNetDevOpenvswitchGetVhostuserIfname() should return 0.
The rest of APIs that assume OVS are not 'fixed' because we still
want them to fail (e.g. getting statistics, plugging interface
into an OVS bridge, unplugging it from an OVS bridge, ...).
The only API that is fixed is
virNetDevOpenvswitchGetVhostuserIfname() because it is called
explicitly when starting a guest (and callers are okay if no name
was found).
The other way to fix this bug seems to be to simply require
'ovs-vsctl' on spec file level, but that is too heavy gun given
that vhostuser is used by a small set of our users (assumption
made on requirements for vhostuser). Also, this way would drag in
yet another dependency for all users (even those who want minimal
libvirt).

Using virtio-blk with SEV on host kernels prior to 5.1 didn't work
because of SWIOTLB limitations and the way virtio has to use it over
DMA-API for SEV (see [1] for detailed info). That is no longer true, so
reword the kbase article accordingly.
For reference, these are the upstream kernel commits lifting the

The output of cpuid depends on the logical processor id the process
runs on, as reflected by the "local apic id" present in cpuid leaves
(eax=1,ebx=0), (eax=11,ebx=0), and (eax=11,ebx=1). This produces
arbitrary changes in the output files that complicate comparisons.
This patch masks the occurences of the local apic id with 0x00, so
that two consecutive runs of "./cpu-data.py gather" produce identical

Now that this function can be called regardless of interface type (and
whether or not we have a conn for the network driver), let's actually
call it for all interface types. This will assure that we re-connect
any disconnected bridge devices for <interface type='bridge'> as
mentioned in https://bugzilla.redhat.com/show_bug.cgi?id=1730084#c26
(until now we've only been reconnecting bridge devices for <interface
type='network'>)

The bridge reattach functionality in this function should be called
for interface types other than just type='network', so make it
callable for any type - it just becomes a NOP for types where no
action is needed.
In the case of <interface type='network'> we need to create a port in
the network driver, and for both type='network and type='bridge' we
need to reattach the bridge device (note that
virDomainNetGetActualBridgeName() gets the bridge name from the
appropriate (and different!) location for either type of interface).
All other interfaces currently require no action.
modifying callers of this function to actually call it for all
interface types is in the next patch. For now the behavior should be
identical pre and post-patch.
(NB: the conn argument can now legitimately be NULL, so we need to
change the ATTRIBUTE_NONNULL() directive for the function's
declaration - I noticed when making this change that argument 3 (the
NetDefPtr) could never be NULL, so I added ATTRIBUTE_NONNULL(3) while
removing ATTRIBUTE_NONNULL(1) (conn)).

dnsmasq usually prints out a version string like this:
Dnsmasq version 2.82 [...]
but a user reported that the build of dnsmasq included with pihole has
a version string like this:
Dnsmasq version pi-hole-2.81 [...]
We parse the dnsmasq version number to figure out if the dnsmasq
binary supports certain features. Since we expect the version number
(and it must be only numbers!) to start on the first non-space after
the string "Dnsmasq version", we fail to parse this format of the
version string.
Rather than spending a bunch of time trying to get pihole to change
that, we can just make our parsing more permissive - after searching
for "Dnsmasq version", we'll skip ahead to the first decimal digit,
rather than just the first non-space.
(NB: The features we're checking for purely by looking at version
number have been in all releases of dnsmasq since at least 2012, so we
could actually just remove the reading of the version number
completely. However it's possible (although *highly* unlikely)
that some new feature would be added to dnsmasq in the future and we
would need to add that code back.)
