Fajar, you da man.  Thanks for all your help.
  
I had two issues that were keeping me from getting networking working
the way I wanted it to and you solved both.  The vif = line hadn't
worked for me because the examples I had seen of using two interfaces
there had either used dynamic mac address creation or had typos in them
that used single quotes at only the beginning of the first interface and
the end of the second interface.  

Manually assigning mac addresses and adding the two extra single quote
marks that differentiate the two interfaces solved all the xen
networking issues I have experienced.  Thanks once again for all your
help.
