Public bug reported: Description =========== At some point pre-check for graphic addresses was moved to check_can_live_migrate_source, https://review.openstack.org/#/c/254709. However, this patch introduced regression, because it only moved a pre-check, but the data needed for the check is not populated at this point.
Steps to reproduce ================== Setup with 2 compute nodes and live migration configured is enough. 1. Edit nova.conf and set vncserver_listen to, e.g., IP assigned to management interface on both compute nodes 2. Try to live migrate an instance Expected result =============== live migration will succeed regardless of IP address set in vncserver_listen (127.0.0.1, 0.0.0.0 or any IP assigned to one of interfaces on a compute node) Actual result ============= live migration fails: 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 =========== 1. Exact version of OpenStack you are running Trunk of nova, commit https://github.com/openstack/nova/commit/bebc86bf5598571a28dd47f17a05dd616fe0f550 2. Which hypervisor did you use?
