[ovirt-users] Re: AMD EPYC 4.3 upgrade 'CPU type is not supported in this cluster compatibility version or is not supported at all'

I tried that too, but it still complains about an unsupported CPU in the new cluster. Even if I leave the cluster level at 4.2, if I update the host to 4.3 it can't activate under a 4.2 cluster. Makes me think something changed in how it verifies the CPU support and for some reason it is not liking my EPYC systems.
