What linux distribution are you using?
You need to be sure to have a libvirt that supports librbd.
the stock ones from redhat/centos 6 do not, for instance.
Can you do rbd commands successfully from the node? Can you
rbd export and do a remote mount outside of opennebula?
Also ceph is fussy about the secrets. I had to define a special
user in ceph just for the libvirt stuff. Here for comparison
is my ceph datastore template.

Hi Steven,
The DISK_TYPE is RBD

Hi all,
I am trying to integrate ceph as the data store for open nebula and i am
successfull able to do so.But when i do a virtualize of an image which is
the ceph data store i couldn't see any rbd snapshot's or clones as i
strongly belive it is still using the default transfer scripts, can one
please help me as any setting to be enabled for the rbd to work properly.
Thanks
