Comment 2 for bug 1399498

This looks like an issue with missing dependencies. We try to keep a record of what packages are needed to make the unit tests pass here http://docs.openstack.org/developer/nova/devref/development.environment.html#linux-systems

So once we find the missing package we should update that document http://git.openstack.org/cgit/openstack/nova/tree/doc/source/devref/development.environment.rst
