These bits were present in the following submission [PATCH QEMU 2.5 v4 0/10] dataplane snapshot fixes + aio_poll fixes and they are unrelated to the migration and safe enough to reach QEMU 2.5. Just sent separately not to miss them.
Dangerous bits will be sent separately when we'll come into agreement of safe bits :) Signed-off-by: Denis V. Lunev <d...@openvz.org> CC: Stefan Hajnoczi <stefa...@redhat.com>
