The OVS database in general specifies state, not actions. That is, if you set no ingress_policing_rate, then OVS takes that to mean that it should turn off ingress policing, so it does. I'm surprised that you actually find...

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 be a bug of incompatible with existing ingress qdisc settings. Thanks, -- Qiu Yu On Wed, Jul 17, 2013 at 8:09 PM, Qiu Yu <unicell@gmail...
