That sounds like overkill to me. If you just want to use the networking 
for IP-based guest-to-host stuff like X11, the easiest thing to do would 
be to use the SLiRP patch. That patch changes SIMH networking to use a 
virtual internal "router" instead of attaching to a physical network 
interface. With the patch, the host system is easily accessible from the 
  guest. The disadvantage is that the guest system does not have an IP 
address visible to anything but the internal router, and therefore it 
isn't possible to connect from the host to a server on the guest.
