Can you provide a VM XML config that shows this behavior on the CPU page? sudo virsh dumpxml $vmname

Thanks, I reproduced. Showing x86 models was a virt-manager error, fixed now:

    capabilities: Fix model list caching for different archs (bz 1451113)


That said, libvirt's virConnectGetCPUModelNames doesn't support aarch64, so you won't get any model names listed in virt-manager now either. That's a separate issue though. (note, you can still manually type a model name cortex-a57 or whatever, we just don't show a list)

Since that fix is just a UI tweak I'm closing as 'upstream', not really important enough to track explicitly backporting IMO
