 What exactly do you mean? In qemu this is not configurable, it's just there. If you don't want to
use it, just don't use it. I see no harm done by adding description of it to domain XML. If you just
add a device, and don't specify <address type='pci'>, it will default to <address
type='virtio-mmio'> as before. Nothing will change regarding old behavior and backwards
compatibility.
