But the support is not complete, some features are not available with Ceph, mainly integration with other storage types, like moving disks to/from Ceph and other storage, live storage migration, image upload and download, and vm leases.

Re: [ovirt-users] oVirt 4.2 CEPH support
if I can just have Ceph...I would be a very happy sys admin! What is stopped you from start use ceph via librbd NOW? All you need is a OpenStack Cinder as volume manager wrapper. You can check librbd version of your hosts via oVirt manager (see attached sceenshot). I read in RHV 4.2 Beta release note that CEPH will be supported using iSCSI. I have tried to check community documentation regarding CEPH support but there was no luck. Do we have such document?

I suppose they have tested ceph iscsi gateway http://docs.ceph.com/docs/master/rbd/iscsi-overview/ And they have certified as compatible. I don't really know why it shouldn't but the certification means that opening a SR to RH when using this setup will get the appropriate help.
