Hi Darrell:
I have tried to manual set flow table and meter action, to arrange meter
action at the end of the flow pipeline(just before the output action), and
delete conntrack related actions. But the iperf result is also around
800Mbps(meter rate is 1Gbps as below).
Should I print any message to verify that userspace meter works as expected
?
ovs-ofctl dump-meters br-int -O openflow13

Hi Darrell:
Sorry, I forgot to tell you the attached flow is based on VM tx direction
rate limit. So the datapath action order is conntrack -> meter -> forward
decision -> output, For the VM rx direction rate limit, the datapath flow is
as below, please help to check, thank you!
For both directions, I think you want to apply the flow meter at the end of the
pipeline.
Can you do that and then check the numbers again.
Also, for the same flow table and meter configuration, the kernel datapath
rate limit is more accurate than userspace datapath.
For VM rx direction rate limit:
