There is no custom scripts or network-nat uncommented in xend-config.sxp. I have double checked that.
Only thing uncommented in network part is
-------------------

(network-script 'network-bridge netdev=eth1')
(vif-script vif-bridge)

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

try
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.

Hello,

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

                                                        vif1.0
                                                        vif2.0
                                                        vif3.0

 No other bridge is present there.                                                     

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


Networking
#
vif         = [
        'ip=192.168.1.158,mac=00:16:3E:19:26:71,bridge=xenbr1'

]

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.
