Hi Matt and thanks for the reply, We do have that commit as found here: [ https://github.com/openstack/nova/blob/dd30603f91e6fd3d1a4db452f20a51ba8820e1f4/nova/db/sqlalchemy/api.py#L1846 ]. If there's anything you'd like to see as we're trying to figure this out I'd be happy to provide {any,every}thing.
