I'm not 100% sure, but I suspect it has to do with the fact that KVM needs to put the vnic/nic into promiscuous mode.  In a zone, this gets harder, because of permissions the process in a zone needs beyond what it would need in the global zone.

I tried to get Joyent's VND upstreamed in time for r151014.  I suspect VND will still hold an improvement on many fronts, including this one.
