There are two migrations in 006_migrations.migrate_vm. The first one
succeeded, but if I'm looking correctly into the logs, Engine didn't
send Destroy to the source host after the migration had finished. Then
the second migration gets rejected by Vdsm, because Vdsm still keeps the
former Vm object instance in Down status.
Since the test succeeds most of the time, it looks like some timing
issue or border case. Arik, is it a known problem? If not, would you
like to look into the logs, whether you can see what's happening?

None I'm aware of.

It's just coincidence that it failed on that patch, so I'm excluding
Edward from the discussion, he is innocent :-).
