Running 9vx is not exactly the same as running a cpu/file server, be it
natively or in qemu/vmware/whatnot. I haven't managed to use 9vx as a cpu
server (although I haven't tried very hard so far) while it's pretty
easy to do what you want once you have set up a "real" cpu server.

So you might want to replace one of the 9vx instances with a plan 9
install and then follow that guide:

that one might be usefull as well:
