[Doug Hellmann <doug.hellmann@xxxxxxxxxxxxx>]

I *just* ran into a problem today triggered by some code moving around in
nova and common. I had to set my driver to
"nova.openstack.common.notifier.rabbit_notifier" (in both files).

I didn't see any errors from that until I tried to launch an instance, so
it doesn't seem to prevent any of the nova services from starting up.
