When migrating, libvirt queries the migration status, and upon migration completions, it closes the migration src. On the other hand, when migration is completed, spice transfers data from the src to destination via the client. This data is required for keeping the spice session after migration, without suffering from data loss and inconsistencies. In order to allow this data transfer, we add QEVENT for signaling libvirt that spice migration has completed, and libvirt needs to wait for this event before quitting the src process.
