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 DS_MAD is ceph TM_MAD is ceph. pasting the result for reference. onedatastore show 100 DATASTORE 100 INFORMATION ID : 100 NAME : cephds USER : oneadmin GROUP : oneadmin CLUSTER : production TYPE : IMAGE DS_MAD : ceph TM_MAD : ceph BASE PATH : /var/lib/one//datastores/100 DISK_TYPE : RBD DATASTORE CAPACITY TOTAL: : 2.3T FREE: : 1.9T USED: : 399G LIMIT: : - PERMISSIONS
