Listing servers with the "--all-tenants" and "--deleted" flag fails due to a bad marker

[Surya Seetharaman]

If "nova list --all-tenants --deleted" is run after the "virtual_interface_obj.fill_virtual_interface_list" migration that was added in Stein it will fail with a "<class 'nova.exception.OrphanedObjectError'> (HTTP 500)" error because of encountering the markers - which are basically one deleted instance per cell with the fake all zeros uuid. This will be a problem until the archival is run I guess. Anyhow while admin listing this marker should not even show up under the list of deleted servers. I guess this should be filtered out in some way.

I am also not sure if the operator is supposed to just archive the nuisance marker because it defeats the purpose of the persistent marker.

yikes, looks like this is just a duplicate of https://bugs.launchpad.net/nova/+bug/1825034 and I just ran along someone else's course then. Marking this as a duplicate.
