Writing the presentation on this for KVM Forum right now.
There are two current variants -- a gateway server which is integrated
into lguest (patches have been posted to the lguest mailing list, but
I can put it someplace else if folks are interested) -- then you
essentially start lguest and feed it an argument specifying where you
server lives (-9p 10.0.0.1:567).
The KVM variant was done by Anthony Ligouri, and it has a server
integrated into qemu. The patched kvm-qemu requires a "-shared
<path>" name to start the server.
In both cases, you just mount -t 9p nodev /mnt -o trans=virtio
Its stable, but preliminary at this point. The main problem being
neither implementation is anywhere near optimal.
Lucho had an older version of a kvm which had an integrated spfs-based
server, but I'm not sure he's ported that forward.
I don't believe there's any support in Plan 9 at the moment for the 9p
virtio channel, but it shouldn't take someone that much to add it.
I'll try putting up something with a bit more more information and the
associated patches on my kernel.org web page.
