It looks like this is a neutron or keystone failure of some sort. As neutron is saying"
Max retries exceeded with url: /v2.0/tokens (Caused by <class 'socket.gaierror'>: [Errno -9] Address family for hostname not supported) and tokens is from keystone. So I don't think this is a nova bug. What is your localrc file for devstack so that we can reproduce the bug. ** Also affects: neutron Importance: Undecided Status: New ** Changed in: nova Status: New => Invalid -- You received this bug notification because you are a member of Yahoo!

In the bug: https://bugs.launchpad.net/nova/+bug/1348103 says it happened in cells environment,but it doesn't happen only in cells environment.This problem should arouse our attention more.
