Maybe a more appropriate approach could be to have a tool/script that does it, as a one time thing. For example, it could make sense in a scenario when Nova DB gets lost or corrupted, a new Nova controller is deployed, and the DB needs to be recreated. Potentially, since Nova DB is primarily a cache, this could be done by 'discovery' (maybe with some manual intervention) - instead of dealing with backup/restore of the DB, or similar approaches.

I feel that Nova managing VMs that it didn't create is not an appropriate use case to support. -- Russell Bryant _______________________________________________ OpenStack-dev mailing list OpenStack-dev@lists.openstack.org http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
