Hi,

you should take a look at the hyper converged way of installing oVirt.
We have a cockpit wizard that does almost everything for you:

https://www.ovirt.org/documentation/gluster-hyperconverged/chap-Deploying_Hyperconverged/

It uses three hosts and collocates the VMs together with Gluster storage.

Best regards
