With outbound QoS setting in Libvirt XML, libvirt will add a tc ingress qdisc for traffic shaping. Then if you set VLAN tag to that tap device, this qdisc will automatically gone by no reason. Could anyone shed some lights where should I look into? I'm really confused and got no clue here. Thanks! Steps to reproduce -- # virsh start instance-name # virsh dumpxml instance-name ...

After some digging in openvswitch code. My wild guess is that vlan tag reconfiguring triggered iface_configure_qos (vswitchd/bridge.c), which in turn called netdev_set_policing to reset ingress policing rate. Although there's no ingress_policing_rate set in my case, existing ingress qdisc still remove by default. Could some openvswitch guy help to confirm and suggest how to fix or workaround? It seems to...
