I do not believe that there is a stand alone DRBD GUI planned at this time.

At least for now, the user most likely will prepare a DRBD Manage cluster up to the point where it's ready to start creating/assigning volumes and then oVirt will take over from there. As far as using DRBD for backing oVirt VMs, this seems to already be > working.

So VMs could have DRBD-backed storage without additional overhead from NFS.
