That vif config can work if there is a another network script like 
network-route in /etc/xen/xend-config.sxp

grep '^(' /etc/xen/xend-config.sxp

and see if there is a custom network script or network-nat is uncommented.
If there is a network-foo uncommented, then copy it from /etc/xen/scripts so we 
can see it.

I guess that you have some custom setup which mixes bridge and route/nat.

There is a xen setup in which "brctl show" gives the following output.

bridge name     bridge id               STP enabled     interfaces
eth1            8000.003048c9d4df       no               peth1


 No other bridge is present 

That means the bridge is eth1, but network configuration for one of the vms  
looks like the following in the configuration file

vif         = [


But there is no network interface like xenbr1 when you type ifconfig .
This setup is working fine. I am not sure how this works. I am new to xen, so 
if anybody help me to understand this setup.
