Yes, this is what I was seeing when testing KVM on System z. The OSA is the cause of the traffic not getting passed on to the originating guest (whether z/VM or KVM). I suppose if you used something like OSA/SF (which I have zero experience with, so don't get your hopes up) to register the MAC with the OSA that things might work. Kind of unreasonable to expect customers to do that for every guest that gets created on a system.
