spice: adding seamless-migration option to the command line
The seamless-migration flag is required in order to identify whether libvirt supports the new QEVENT_SPICE_MIGRATE_COMPLETED or not (by default the flag is off). New libvirt versions that wait for QEVENT_SPICE_MIGRATE_COMPLETED should turn on this flag. When this flag is off, spice fallbacks to its old migration method, which can result in data loss.
