IIRC, oVirt is getting the CPU support from libvirt, so if libvirt supports it, oVirt should support it.
Regarding AMD - I didn't see any new patches from AMD for the new Zen-2 support, and I'm not sure if something changed from Zen-1/Zen+ regarding virtualization...

Hi everyone,
     I am interested in adding Ryzen/Ryzen 2 / Ryzen 3 CPU support to OVirt. I've seen a few references on the net to people adding in EPYC support by updating a PostgresSQL DB table (e.g. https://lists.ovirt.org/archives/list/users@ovirt.org/thread/T3XL6NU7SUPYLYFL4TEKLOZTBWY6ID3S/). 

Would this really be all that is needed? If so, how do I determine the correct string to add to the table?  If EYPC is "7:AMD EPYC:svm,nx,model_EPYC:EPYC:x86_64;", would Ryzen be something like "7:AMD RYZEN:svm,nx,model_RYZEN:RYZEN:x86_64;"?
