[ovs-discuss] How to use OVS with real Host ?

[Ben Pfaff]

It looks like all you need is:
	ovs-vsctl add-br br0
	ovs-vsctl add-port br0 eth0
	ovs-vsctl add-port br0 eth1

What do of-host1 and of-host2 represent?

Don't drop ovs-discuss at openvswitch.org this time or I'm going to stop
trying to help.
