[libvirt PATCH] apparmor: Enable passt support
by Andrea Bolognani
passt provides an AppArmor abstraction that covers all the
inner details of its operation, so we can simply import that
and add the libvirt-specific parts on top: namely, passt
needs to be able to create a socket and pid file, while
the libvirt daemon needs to be able to kill passt.

[PATCH] rpc: genprotocol: Always apply fixups to rpcgen's output
by Peter Krempa
The platform check which determines when to apply the fixups mentions
all officially supported build targets (per docs/platforms.rst) thus
it's not really necessary.
Additionally while not explicitly written as supported the check does
not work properly when building with the MinGW toolchain on Windows as
it does not apply the needed transformations. They are necessary
there the same way as with MinGW on Linux.

[PATCH v2 0/8] migration/migrationpin:support migration pin
by Jiang Jiacheng
Support set the CPU affinity of the live migration threads to improve
the migration performance in specific cases. By default, the migration
thread shares CPU resources with the VM process. With those API, support
pin migration thread to expected CPU list to avoid preempting CPU
resources of VM process.
Use the following methods to implement migration thread pin:
- set the cpulist by virsh command 'virsh migrationpin' or
migration param 'migration.pin'. These settings affect
only the next migration
- continuously query migration thread information[1] during the
migration process until matches the thread number desired or
migration finished unexpectedly
- pin migration thread to expected cpulist, we can set/change
the cpulist by 'virsh migrationpin' during migration at anytime
Note that only support pin main thread of migration(live migration)
and parallel send threads now.
diff to v1:
- add qmp command to query migration thread information
- change the method of get qemu's migration thread info, from qemu
event to qmp commands.
- unified the interface of common migration and parallel migration.
