Thanks for your reply. I can see that OpenvSwicth created the bridge br0.
But when I update my domU.cfg file to update the network bridge to br0 from
eth0, domU does not boot and I get the following error
$ sudo xm create domU.cfg
Using config file "/etc/xen/domU.cfg".
Error: Device 0 (vif) could not be connected. Hotplug scripts not
The bridge should be visible to Xen right? I can see the bridge when I run
ettm at ettm:~$ ifconfig
br0 Link encap:Ethernet HWaddr 00:25:64:49:d7:94
inet addr:128.xxx.x.xx Bcast:184.108.40.206 Mask:255.255.255.0

TX packets:1313 errors:0 dropped:0 overruns:0 carrier:0
RX bytes:2297956 (2.2 MB) TX bytes:463836 (463.8 KB)
Do I need to do something else to make domU use br0 created by open vswicth?
I appreciate the help.
