Actually, what I wanted to do was assign a xen virtual front-end 
ethernet to domain0, in a similar manner that one would assign one to 
another domain (nics = 1 in config file).  I can't seem to do that for 
domain0.  It seems like the options for domain0 ae a bit limited.
I actually have noticed some wierdness with ARP resolution, and I had 
suspected the mac addresses.  Linux in the past has has some not quite 
strict behavior when it came to ARP, and maybe that has also come into play.
