Fixes bug 918615 start_instance doesn't need to go through scheduler because it still has instance['host'] set and resources are still accounted for in the scheduler, which means there's still room to restart it on its assigned host (even though it is deleted from the virt layer) Change-Id: I3cdd73b7ad2297b57f7e36be84819ff233ac8f08
