Hi Everyone, This is my set up.

       +-----------------+             +-----------+
       |   VM1         |              |   VM2   |
      +................  +             +-----------+
                |                              |
      + ---- - | ---------------------- ---   | ---------------------+
      |   +--------------------------------------------+           |
      |    |             OpenVswitch            |            |
      |    +________________________ +           |
      |              Host Machine                            |
      +------------------------------------------------eth0------+
                                                          |
                          +-----------------------------+
                    +----|--------+
                    |   LAN     |
                    +------------+
                         |
                +------------------+
                 |     Linux      |
                 |    Machine  |
                 +-----------------+
VM1 and VM2 are running on Host machine. According the paper "Extending
Networking into the
Virtualization Layer" from ovenvswitch, we can create virtual private
networks between "VM1 and Linux Machine"
and "VM2 and Linux Machine". The main intension is here that the traffic
from VM1 to VM2 should travel
through Linux Machine ( Now its going directly from VM1->VM2).

Help in this regard is highly appreciated.
Thanks,
Ramana.
