This stack trace indicates a loop, so I'm not sure if there is a second problem or if the loop remains in your configuration in the second case. OVS has some basic kernel loop prevention but ultimately it's not really possible to prevent all loops (particularly when going through the IP stack) without preventing some legitimate use cases. _______________________________________________ discuss mailing list discuss@openvswitch.org http://openvswitch.org/mailman/listinfo/discuss
