Howdy all, FYI we have gate failures of the recently added test_*_with_qos_min_bw_allocation tests [1] in the nova-multi-cell job on the master, stable/victoria, and stable/ussuri branches. The failures occur during cross cell migrations. I have opened a bug for the failure on the master branch: * https://bugs.launchpad.net/nova/+bug/1907522 The issue here is that we fail to create port bindings in neutron during a cross cell migration in the superconductor: nova.exception.PortBindingFailed: Binding failed for port <port uuid> and that corresponds to a failure in the neutron server log where it fails the port binding with: neutron_lib.exceptions.placement.UnknownResourceProvider: No such resource provider known by Neutron I don't yet know what is going on here ^. For the bug on stable/victoria and stable/ussuri I have opened this bug: * https://bugs.launchpad.net/nova/+bug/1907511 and have a WIP stable-only patch proposed that needs tests: https://review.opendev.org/c/openstack/nova/+/766364 I just wanted to see ASAP if the nova-multi-cell job will pass on it. The issue here ^ is that during a cross cell migration, we aren't targeting the cell database for the target host when we attempt to lookup the service record of the target host. For the stable branch failures I think the failure rate is 100% and it looks like it might also be 100% for the master branch failures.
