Bug Description

I'm getting the following failure in nova-api.log when trying to run the nova smoketests w/ nova trunk.

I've been seeing this failure for almost 2 weeks now although due to a variety of issues (PPA packaging, networking code chaos, etc.) I'm not sure which changeset caused the exact failure.

This seems to fix it although I'm not entirely sure some of the networking code changes aren't to blame as well (related to fixed_ips not getting unset or something).
