Does OVN (with Yoga release) use OVS or Linux TC for QoS implementation? #256
Comments
@LorenzoBianconi Do you have any comments for this issue ? |
@nhtung96 I guess ovn/ovs for incoming traffic rate limiting is using ovs-meters instead of tc (tc qdisc are used for egress traffic shaping if ovs-kdp is used). Can you please try dumping ovs meters? |
@LorenzoBianconi Thank you for your reply. I did try dumping ovs meters at compute node but didnt see the meter with the rate I configured. (actually I don't how meter id link to ovn nb/sb db qos rule, just grep the rate). ======OVS check==== |
Hi team, I got a problem that my VM port does not have traffic rate limit, although it has been applied QoS policy (100Mbps) . I checked the northbound ovn-nbctl qos-list and found qos rule associated to VM port. It is OK. However, I looked at ovs-vsctl list interface <vm_tap_port> and I saw ingress_policing_rate=0 (burst=0 also), it means OVS didn't play a role in QoS rate limit, didnt it? I also tried to set ingress_policing_rate=100000 but it did not have improvement for actual rate limit.
