Description of problem: It could be great if we can add more than 1 export domain in oVirt (for Q/A, backup purposes...)
This is already possible today using storage domains. You can clone the VMs from one storage domain to another or move them and connect\disconnect of the SDs from one dc to another and one rhev to another. We planned to deprecate the export domain in future version and this RFE is not likely to happen.
