Thanks. I did solve it by changing the boot priority of the xend startup script from 98 to 09. This way it would start before eth0 would come up.

Wow! I didn't know xend had to be up before network interfaces were brought up. Could you or someone tell me why? Or point to a place which explains this?

Thanks

And that exactly the problem.
xend starts from a startup script and shuts down eth0.
I have to physically login to the machine and restart xend using / etc/init.d/xend restart, and only then eth0 comes up again along with all the other virtual interfaces.

Networking is breaking because eth0 is *already* up when xend starts. You need to tell your distro not to start eth0 automatically (in centos I believe you need to edit the /etc/ sysconfig/network-scripts/ifcfg-eth0 file), and simply let xend do it. It should then start it up in the correct state.
