This patch checks the revision of QEMU and libvirt to ensure support
for VFIO SR-IOV device migration.
It also updates the _live_migration_operation() function, particularly
the get_updated_guest_xml() function, to map source PCI addresses
to destination addresses in the destination XML file, using the data
provided by the LiveMigrateData object.
The target goal of these series of patch is to enable VFIO devices
migration with kernel variant drivers.
