I asked fo this thinking bypass_guest_pf may help show more
information. But thinking a bit more, it will not.
I think I do know what the problem is. I will try it out. Is there a
free clone (like centos) available somewhere?
This patch tracks down emulated accesses

Normally, tap always reads packets and simply lets the client drop them if it
cannot receive them. For virtio-net, this results in massive packet loss and

How about the other way round: when the vlan consumer detects it can
no longer receive packets, it tells that to the vlan. When all vlan
consumers can no longer receive, tell the producer to stop
producing. For the tap producer, this is simply removing its fd from
