[SL] Take a look at either of these blog posts: <http://blog.scottlowe.org/2012/10/30/running-host-management-on-open-vswitch/> <http://blog.scottlowe.org/2013/12/02/connecting-bare-metal-workloads-using-gre-tunnels-and-ovs/> Both posts illustrate the use of an OVS internal port as an IP interface.
