Open vSwitch does have a fairly small limit on port mirroring policies, but the limit is higher than 1. I think the limit is 32 or 64. So, I think you must have a mistake in how you are configuring it. > What is more, sometime, I want the packet to be duplicated and forward to > an VM on other host.

I haven't configured an OpenStack environment myself so I don't have enough knowledge to give you a direct answer. Perhaps someone else will step up. _______________________________________________ discuss mailing list discuss@openvswitch.org http://openvswitch.org/mailman/listinfo/discuss
