Public bug reported:
When VNC or SPICE is configured to listen only at a specific IP address
(e.g. on the management network in an OpenStack-Ansible deploy), the
check performed by check_can_live_migrate_source always fails, because
check_can_live_migrate_destination does not return the attributes needed
to retrieve listen_addrs using libvirt_migrate.graphics_listen_addrs.
Steps to reproduce:
* Deploy OpenStack-Ansible from master.
* Create an instance.
* Try to live migrate the instance to another host.
Expected result: live migration should be carried.
Actual result (nova-compute.log):
ERROR oslo_messaging.rpc.server MigrationError: Migration error: Your
libvirt version does not support the VIR_DOMAIN_XML_MIGRATABLE flag or
your destination node does not support retrieving listen addresses. In
order for live migration to work properly, you must configure the
graphics (VNC and/or SPICE) listen addresses to be either the catch-all
address (0.0.0.0 or ::) or the local address (127.0.0.1 or ::1).
Environment:
* Multi-node OpenStack-Ansible deploy.
* Nova from git (commit 32b7526b3cf40f40c5430034f75444fc64ac0e04).
* Libvirt + KVM
