I'm no expert on this stuff but I'll give it a try:

The vif is usually vif<DomID>.<ethN>.
The vif that is selected to use is based on the original default  
route, but things get confused because its the wrong interface then  
you selected.
I believe (completely by inspection) that you want to change the  
following in xend-config.sxp:
  (vif-script vif-bridge)
to be:
  (vif-script vif-bridge vif=0)

This should force the selection you want and may get the routes correct.

BTW: If you would like to have DomUs to have access to the outside  
world then you also want to make sure you have "ip forwarding" turned  
on:
  # echo 1 >/proc/sys/net/ipv4/ip_forward

forever change  IP_FORWARD= from "no" to "yes" in /etc/sysconfig/sysctl
