The Cinderlib is a Cinder. Cinder always have native RBD driver, but seems 
oVirt developers don't know about it
Yes, you can add write the vdsm hook and modify the xmldom, but take a look - 
it's just another hack of hack of hack. May be better stop hack oVirt and 
choose OpenStack or Proxmox with normal RBD support? 🙂


Cheers,
