Public bug reported: I have setup a fresh OpenStack HA Pike environment on Ubuntu 16.04.3. Live migration has been enabled and works so far. As storage backend I am using Ceph v12.2.0 (Luminous). When you attach a secondary volume to a vm and try to live migrate the vm to another host, it fails with the following exception:
