# Libvirt
Depending on the case sometimes libvirt also needs changes - Focal
already has /usr/share/libvirt/cpu_map/x86_EPYC.xml which contains the
base version and v3 will plug in there. But for "Epic-Rome" there isn't
anything upstream in libvirt.
I think this will therefore be non-selectable through libvirt - it will
still help qemu if called directly, but if you want this we might
consider poking libvirt upstream together later on (after testing if it
really is missing to us int he backports).
