RE: [Xen-users] Lots of udp (multicast) packet loss in domU

We are running xen 3.3.0 on a 2.6.18 dom0 and domU, but my domU gets 100% of 
the traffic even when its not joined to any of the groups.  Do you know which 
recent kernel versions would support igmp snooping / pruning such that my 
domU's only get what they are registered for?

One last question / idea: I have read a few times I think about ipv6 related 
issues... we currently have ipv6 enabled in our kernels but we are not using 
it, do you think that disabling it would achieve anything?

Best,
