Public bug reported:

I do a live-migration from host1 to host2
live-migration successfully to but the instance's host is not set back to host2 yet before host1's nova-compute service crash(ctrl+c to stop it)

nova list show that the instance is still active(actually , it is done
the migration and I can see it host2 by virsh list)

show this instance, the instance's host is still host1(due to host1's
compute crashed an no chance to set it yet).

after that. do a reboot on this instance, failed due to the instance can
not be found from host1 host(yes, it is)

and nova set it to error status(but the instance is still running on
host2)
