Thanks Eduardo!
I think I can find a third server to build a glusterFS storage. So the first step will be to install a self-hosted engine on the new server and start building a glusterFS storage.
You´ll need to build the Gluster storage first, as you´ll want to install the Hosted Engine _in_ the HA Gluster storage, right? /K
IS there any easy way to migrate existing 5 VM's running on the second bare-metal oVirt host, right? I found a little bit tricky moving oVirt backups between the hosts (at least I failed to replicate the existing VM's on the second server).
Regards, Artem

For HA you will need some kind of storage available to all the compute nodes in the cluster. If you have no external storage and few nodes, I think your best option for storage is gluster , and the minimum number of nodes you will need for HA is 3 (the third gluster node can be metadata-only, but you still need that third node to give you quorum, avoid split-brains and have something that you can call "HA" with a straight face.

Looking for a design advise on oVirt provisioning. I'm running a PoC lab on single bare-metal host (suddenly it was setup with just Local Storage domain) and no I'd like to rebuild the setup by making a cluster of 2 physical servers, no external storage array available. That are the options here? is there any options to build cheap HA cluster with just 2 servers?
Thanks in advance!
