2 – adding GRE tunnels & VM’s

After building 2 KVM Hosts with their own openvswitch 1.0 implementation, we can add GRE encapsulation to allow these VM’s connect. Most of this procedure was built from : http://openvswitch.org/ovs-vswitchd.conf.db.5.pdf. Notice in this page that “Mirroring to a GRE tunnel has fewer caveats than mirroring to a VLAN and should generally be preferred.”
