At this time, it appears that oVirt is pursuing a strategy of Ceph/RBD integration by proxy of OpenStack. There is a feature scheduled for oVirt 4 to integrate with Cinder, specifically calling-out the RBD use-case [1].
On the iSCSI front, RBD should be functional with STGT and LIO in active/passive mode. There is active development to add support for RBD+LIO active/active [2]. The disadvantage of the iSCSI design is that it adds an extra hop between your VMs and the backing Ceph cluster.
