<p>Exporting the VMs to an export storage domain on the first
server, copying the files to another export storage domain on the
second server and importing it should work. What kind of problem
did you find?</p>
<p>As for the order of doing things, my first oVirt lab was a 3-node
setup with gluster (oVirt version 4.0). I found this guide
helpful:</p>

<p>I see there is a new version of it:</p>

<p>If I understand correctly you plan to re-use the server you
already have. I think you will probably find it much easier have
to export your VMs, re-deploy and import your VMs back. It means
some downtime, but you seem very constrained on the hardware
available and there is not much room to manouver...<br>
</p>
<p>Good luck!<br>

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. 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).

<p>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.<br>

<div>Looking for a design advise on oVirt

bare-metal host (suddenly it was setup with just
Local Storage domain) and </div>
<div>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? </div>
