Bug Description

Roll-back of destination node in case of live-migration failure depends on block-migrate flag that passed by operator. So it's possible to leave destination node in inconsistent state by passing block-migrate flag, over api.

What flags did you pass to the live-migration? Were the hosts on shared storage, or local storage? What is the reason for the rollback? What do you mean by "leaving the destination node in an inconsistent state"?
