I am following the cookbook at http://openvswitch.org/?page_id=146 . I don't want to create one single bridge, but I want to be able to have open vswitches running on different hosts and still be able to talk to each other. In short, I want to remove the eth0 - eth0 connection mentioned in the cookbook and replace it with a tunnel if possible, so that a VM on host1 can communicate with a VM on host2.
