I am trying to get a pool going within oVIRT. When I go to create the pool it errors out on trying to spin up the instances. However if i manually spin up an instance from the Template it comes up with no issues. I noticed inside the vdsm.log i see messages about "'Cannot get parent volume' - code 216", however I looked at the NFS share and the permissions appear right vdsm:kvm
