Comment 6 for bug 1800472

The confusing thing is the API fixture should setup and create a service record:

https://github.com/openstack/nova/blob/4f5cb30a2f88965772bcbff0a19a1dcfcd3836c6/nova/tests/fixtures.py#L931

https://github.com/openstack/nova/blob/4f5cb30a2f88965772bcbff0a19a1dcfcd3836c6/nova/api/openstack/wsgi_app.py#L44

But maybe that's getting created by default in cell1 when it should just be getting created in whatever database connection is configured for the API service (which probably just defaults to cell1).
