Hi all, Now, I successfully created two tunnels between External OpenvSwitch and DomUs. I added two tunnels as ports to bridge with out assigning any IP addresses to tunnels.
Thanks to Ben Pfaff for his explanation, Initially I thought that IP assignment is required to each tunnel like in normal Linux machines, but this is not the case with OpenvSwitch (create a bridge and add tunnels as ports to bridge are enough).

That's easy.
