I am not sure of its status -- it looks like it was part of 3.6 planning but it recently was moved to 4.0 on the wiki. There is a video walkthrough of the running integration from this past August [1]. You would need to just deploy Cinder and Keystone -- no need for all the other bits. Again, it appears that oVirt might even have some development to containerize a small Cinder/Glance OpenStack setup [2].
