OVS doesn't queue packets like that, nor does it even have a mechanism to do so. I can believe that something in the network is doing it, but it's pretty unlikely to be in the core of OVS. In your monitoring VM, how are you printing packets? _______________________________________________ discuss mailing list [email protected] http://openvswitch.org/mailman/listinfo/discuss
