There is no behavior changes after the QoS command.


And I found this error message in the ovs-vsctl.log

	Dear all:

	I am using ovs 1.1.0pre1 on Xen server 5.6.0.

	There are VM1 (vif1.0) in the host server.

	Xenbr0 has vif1.0 and eth0(My computer is here with cross-over RJ cable) connected.


	Then I entry the commands bellow.


	ovs-vsctl set interface vif1.0 ingress_policing_rate 10000

	ovs-vsctl set interface vif1.0 ingress_policing_burst 1000



	iperf –s (PC).

	iperf –c my pc’s ip  (VM1)

	After 10 seconds , VM1 screen shows 80Mbit/sec


	I thought the speed should near 10Mbit/sec , did I do anything wrong?

	Or there are something else I should know?


Did you see any change from the previous behavior without ingress policing?  Are there any error messages in the logs?
