If I’m not wrong GlusterFS in oVirt requires 3 hosts.
Wasn't there a Ridning Hood not long ago that said they'd change it down to 1 with 4.2, just to have something to get you started? To lower the bar for POC systems, like all-in-one?

Here’s the RHHI guide, it’s pretty much the same for oVirt: https://access.redhat.com/documentation/en-us/red_hat_hyperconverged_infrastructure/1.1/html/deploying_red_hat_hyperconverged_infrastructure/
