[ovs-discuss] Test OVS kernel module using only one machine

[Ahmed Talha Khan]

Hey Markus,

After clearing some things out i was able to get the traffic into ovs
with the approach that you mentioned. Thanks

@Kyle,

When I add an internal interface using
ovs-vsctl add-port br0 port0  --  set  Interface  port0 type=internal

and then try to bring up this interface,
ifconfig port0 up

My machine freezes permanently. Its a complete hang and i have to
power-rest the machine to bring it back up. I am on a VM.
