The virtio portions of the kernel were just added in 2.6.24, the
server portion has not yet been integrated into the kvm-qemu mainline,
but is fairly trivial to merge. You can also use the TCP/IP version
of the 9p transport to get access to synthetic file systems until all
the virtio stuff gets merged.
If you really want to stick with the 2.6.22 kernel, it may be possible
to build 9p modules with the back ported virtio changes (in fact we
were doing just that for a bit).
