'kvm_9p' isn't created as a device under /dev, it's just a name used
internally by 9pnet_virtio (and located under sysfs).

I couldn't figure out which params the kernel would expect to boot using
9p over virtio (theres no device name to begin with).

I've also couldn't find anything that suggested it's possible to boot
using virtio-9p as rootfs.
