Re: [ovirt-users] Advise needed: building cheap HA oVirt cluster with just 2 physical servers

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.
