starting VM on target).
migrate-start-postcopy command doesn't enable
Hi ,Vladimir
sometimes ,post-copy mode is not the best choice. For instance, Supposing

Usually,we use the precopy or postcopy mode to migrate block dirty bitmap.
but if block-dirty-bitmap size more than threshold size,we cannot entry the
