I don't think that you can achieve it with only 2 nodes, as you can't protect yourself of split brain. Ovirt supports only glusterfs of replica 3 arbiter 1. If you create your own glusterfs , you can use glusterd2 with a "remote arbiter" in another location. That will give you protection from split brain and as it is remote - the latency won't kill your write speed.
I can recommend you to get a VM in your environment (not hosted on any of the 2 hosts) or a small machine with a SSD and use that as pure arbiter. Using one of the 2 nodes as arbiter brick is not going to help, as when that node fails - the cluster on the other node will stop working. It's the same with hosting NFS on one of the machines. As far as I know DRBD is not yet fully integrated, but you can give it a try.Still, using only 2 nodes gives no protection from split brain.
