One thing I notice is that the libvirt xml from EPYC at /usr/share/libvirt/cpu_map/x86_EPYC-Rome.xml ofc is not updated but also a new one for using -v4 is not rendered.
That means I can't instruct nova to use EPYC-Rome-v4 with
2024-04-16 07:30:04.939 4168598 ERROR oslo_service.service nova.exception.InvalidCPUInfo: Configured CPU model: EPYC-Rome-v4 is not correct, or your host CPU arch does not support this model. Please correct your config and try again.
Do we need a patch for libvirt as well to have this working?

# grep -i epyc /etc/nova/nova.conf
cpu_model = EPYC-Rome-v4
because nova will stop working with error
