I created a new DC "Custom", checked compat level is 4.6.
Within that, created a new Cluster "Custom", arch is x86_64, and ..
you're right! It was a UI issue of some kind because now I see the
scrollbar on the right and there are many more machine types.
I selected AMD EPYC, so let's see how it goes creating a host.
Sadly that didn't fix the problem, I'm still getting:
Host ovirt4410 moved to Non-Operational state as host CPU type is not supported in this
cluster compatibility version or is not supported at all
and in engine.log:
2022-02-02 13:35:01,713Z ERROR

Mousing over the status, it says it's missing 'model_EPYC' and 'svm'
flags. The first one is weird because the emulated model in the guest
is:
model name : AMD EPYC-Rome Processor
The second one is correct because I guess KVM is masking this flag
from the guest:
flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36
clflush mmx fxsr sse sse2 syscall nx mmxext fxsr_opt pdpe1gb rdtscp lm rep_good nopl cpuid

Is there not any way to ignore this stuff? I really don't care that
this node which is only going to be used for testing won't run VMs
optimally. For comparison VMware ESXi 7 also raised minimum CPU types
substantially, but offers a simple (unsupported) opt out.
