The interface is using physical addresses (or physical page numbers), so
MMU or not - it doesn't care.

Now, whether the existing implementation of the drivers (or host-side
implementation of the virtoo device) would work, that's another
question. I see nothing in virtio-mmio driver that clearly wouldn't
work, but you never know...
