Open vSwitch deletes all the flows if you change its configuration from "no controllers" to "at least one controller" or vice versa. However, a controller that can't be reached still counts as "at least one controller". So: you could configure an invalid controller (an IP address or port that is not reachable), add your flows, and then configure your correct controller. _______________________________________________ discuss mailing list discuss@openvswitch.org http://openvswitch.org/mailman/listinfo/discuss
