Hi,<br>
In addition to Dan's comments you can also take a look at the
following link <a class="moz-txt-link-freetext" href="http://wiki.openstack.org/ConfigureOpenvswitch">http://wiki.openstack.org/ConfigureOpenvswitch</a>.<br>
Thanks<br>

If you are using tunneling, the traffic will exit out the NIC
based on<br>
your physical server's routing table and the destination IP of
the<br>
tunnel. For example, if your physical server is tunneling a
packet to<br>
a VM on a physical server with IP W.X.Y.Z, the packet will
leave<br>
whatever NIC has the route to reach W.X.Y.Z .<br>
