Public bug reported:
While working on a patch for
https://bugs.launchpad.net/nova/+bug/1946752, I ran into the following
bug.
Description
===========
If a VM is in paused, and it live-migrated twice, it is lost.
Steps to reproduce
==================
$ openstack server pause <UUID>
(wait until done)
$ openstack server migrate --live-migration <UUID>
(wait until done)
$ openstack server migrate --live-migration <UUID>
Expected result
===============
Migration succeeds and VM is usable afterwards.
Actual result
=============
