Subject: [PATCH] qemu: Add support for direct and extended tlbflush features
They require special handling since they are dependent on the basic
tlbflush feature itself and therefore are not handled automatically as
part of virDomainHyperv enum, just like the stimer-direct feature.

Subject: [PATCH] qemu: Enable I/O APIC even more frequently
In my previous commit v10.10.0-48-g2d222ecf6e I've made us enable
I/O APIC when there is an IOMMU with EIM. This works well. What
does not work is case when there's just an IOMMU without EIM but
with 256+ vCPUS. Problem is that post parsing happens in two
stages: general domain post parse (where
qemuDomainDefEnableDefaultFeatures() is called) and then per
device post parse (where qemuDomainIOMMUDefPostParse() is
called). Now, in aforementioned case it is the device post parse
phase where EIM is enabled but the code that would enable
VIR_DOMAIN_FEATURE_IOAPIC has already run.
To resolve this, make the domain post parse callback "foresee"
the future enabling of EIM so that it can turn on I/O APIC
beforehand.

Subject: [PATCH] qemu_migration: Do not consider post-copy active in
postcopy-recover
The postcopy-recover migration state in QEMU means a connection for the
migration stream was established. Depending on the schedulers on both
hosts a relative timing of the corresponding MIGRATION event on the
source host and the destination host may differ. Specifically it's
possible that the source sees postcopy-recover while the destination is
still in postcopy-paused.
Currently the Perform phase on the source host ends when we get
postcopy-recover event and the Finish phase on the destination host is
called. If this is fast enough we can still see postcopy-paused state
when the Finish phase starts waiting for migration to complete. This is
interpreted as a failure and reported back to the caller. Even though
the recovery may actually start just a few moments later.
To avoid this race we now don't consider post-copy migration active in
postcopy-recover state and keep waiting for postcopy-active event (in
the success path). Thus the Finish phase is entered only after the
migration switches to postcopy-active. In this state QEMU guarantees the
destination already switched at least to postcopy-recover and we won't
be confused be seeing an old postcopy-failed state.
