I.e. ideally i'd like to have no image at all - just a > guest kernel and a directory hierarchy for the guest filesystem. >>From what I can tell, not currently. '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. -- Sasha.
