[PATCH 0/2] not use multifd during postcopy

Posted by Wei Yang 6 years ago

We don't support multifd during postcopy, but user still could enable
both multifd and postcopy. This leads to migration failure.

Patch 1 does proper cleanup, otherwise we may have data corruption.
Patch 2 does the main job.

BTW, current multifd synchronization method needs a cleanup. Will send another
patch set.

  migration/multifd: clean pages after filling packet
  migration/multifd: not use multifd during postcopy
