Public bug reported:

Due to this change:

https://github.com/openstack/nova/commit/92074e0fde7da6262897b08d100fedcfe7e4940f

I'm always hitting this locally now:

http://paste.openstack.org/show/191892/

Looking at the code, I don't see how it wouldn't fail since the
neutronv2 API code calls base_api.update_instance_cache_with_nw_info
which eventually calls instance.save() and the
nova.objects.Instance.save() method isn't mocked out, which talks to the
DB API and that blows up since we don't have a database connection.

I'm not sure how this is passing in the gate, but looking at the code
it's clearly wrong.  There must be some test ordering issue that makes
this pass.
