Bug Description

In stable/mitaka, it was possible to do a live migration with ceph.

However, this fails on Master:
$ nova live-migration 3113f24e-4149-4a57-9918-a8d5e9d2add4

Confirmed that this is regression in nova. In this patch https://review.openstack.org/#/c/254709 graphics checks have been moved to check_can_live_migrate_source, but we never moved setting up graphic addresses to check_can_live_migrate_destination
