In postcopy I added a 'migration_already_active' function to merge all the different places that check for ACTIVE/SETUP etc. ( http://lists.gnu.org/archive/html/qemu-devel/2014-07/msg00850.html ) > + /*TODO: COLO checkpointed save loop*/ > + > + if (s->state != MIG_STATE_ERROR) { > + migrate_set_state(s, MIG_STATE_COLO, MIG_STATE_COMPLETED); > + } I thought migrate_set_state only changed the state if the old state matched the 1st value - i.e. I think it'll only change to COMPLETED if the state is COLO; so I don't think you need the if.
