I've the same problem using the latest RDO Juno Milestone 3 release and I guess the problem has to do with:

compute_driver=novadocker.virt.docker.DockerDriver

setting in nova.conf, if I set it, then I can't restart per "openstack-service restart" Job for openstack-nova-compute.service failed.

$ systemctl status openstack-nova-compute.service

gives me:

Update 2014-10-11

This issue was simply solved by running:

$ pip install pbr

and running openstack-service restart on the latest RDO Juno M3 release (as per today 2014-10-11). (I also installed the latest docker 1.2.0 on CentOS 7).

But the whole thing is far from stable, at least at this time.
