Bug description:
  When building the Debian package of Nova for Mitaka b3 (ie: Nova
  13.0.0~b3), I get the below unit test failures. Please help me to fix
  this. I'm available on IRC if you need more details and a way to
  reproduce (but basically, try to build the package in Sid +
  Experimental using the sources from git clone
  git://git.debian.org/git/openstack/nova.git).
