Hi Fajar,

Is is possible for all practical purposes that we create different bridges for each domU ? An traffic for each of them go through their respective bridges ? If yes, can this be automated in some way ?

Sorry if i sound stupid.

P.S. : I am still waiting for the new centos5.3 machine to come in, where i wish to run the ebtables testing.

It used to be so. Not anymore.
On RHEL 5.2 that limit was removed. I'm not sure about the "vanilla" xen though.

Anand's situation is different from what you describe. All domUs are
on the same network (same bridge), so on default setup it's possible
(for example) for one domU to assign IP address that was allocated to
other domUs.
