zaja1kunHi! I have troubles using QoS in OpenStack with OVN. Is there anybody who can help me?14:46
russellbwhat's the trouble?14:46
zaja1kunI deployed OpenStack via vagrant using standard config from networking-ovn (master branch). The only changes I made were enabling qos on controller node and enlarging RAM to 8Gb on computes. When I try to apply policy to port, I can find it in ovn-nb and ovn-sb, but not on OVS14:50
russellbzaja1kun: OK, let me try a quick test ...14:52
zaja1kunrussellb: Many thanks for your participation)14:58
russellbzaja1kun: it doesn't set the values in ovs15:04
russellbit creates a queue for the appropriate interface, and sets those options on that queue15:05
russellband in openflow, it specifies the appropriate queue ID15:05
russellbtrying to find the right command to view the settings ...15:05
russellband i've also added a TODO item to document this topic for OVN :)15:08
zaja1kunThat's a surprise for me. In OpenStack with OVS driver Neutron bandwidth limiting policies were mapped to ingress_policing_rate and ingress_policing_burst fields on OVS15:10
zaja1kunNevertheless, applying policy has no effect15:11
russellbright, this works differently15:12
russellbi imagine you use "tc" to view the settings15:12
russellbbut i'm still fighting getting qos enabled in my devstack env15:12
russellbwe allocate a queue id for each port that has qos settings, and use openflow to set the proper queue ID for each port15:14
zaja1kunrussellb: >> i imagine you use "tc" to view the settings >> No, I just check working time of scp copying 10Mb file from one cirros to another)15:14
russellbzaja1kun: are both cirros instances on the same host?15:14
zaja1kunrussellb: >> are both cirros instances on the same host? >> No15:15
russellbhow are they communicating?  over a tunnel?15:15
russellbor via a provider network?15:15
zaja1kunBoth instances are connected to provider net15:16
russellbah ha15:17
russellbthat's a bug15:17
russellbi just discovered that recently .... sorry15:17
russellbif you switch it over so that they're talking over a tunnel, it should work15:17
russellbbut i noticed it doesn't work for provider networks ... oops15:18
zaja1kun>> i just discovered that recently .... sorry >> Happy to be helpful)15:18
russellbzaja1kun: feel free to file a bug against networking-ovn to track it if you'd like15:19
russellbthe fix will be in OVN itself, but sometimes we track these things that we care about in the networking-ovn tracker anyway15:19
russellbif you file the bug, i can add some more detail about it15:19

zaja1kunrassellb: Is that enaugh? https://bugs.launchpad.net/networking-ovn/+bug/164852515:28
openstackLaunchpad bug 1648525 in networking-ovn "QoS doesn't work in provider networks" [Undecided,New]15:28
russellbzaja1kun: yes, thank you!15:28
zaja1kunrassellb: Thanks for your help!15:29
russellbzaja1kun: someone on my team is planning to work on this i think, we'll update the bug when it's worked on15:29
zaja1kunrussellb: Great) And I have one more unrelated question. How is the work on private-provider routing is going15:37
russellbneutron routed networks support?15:37
russellbthat is supposedly implemented for OVN15:38
russellbi don't know how well tested it is though15:38
russellbzaja1kun: can i ask an unrelated question?  If you're willing to share, i'm interested in what company you're from and your general interest / usage of OVN15:38
russellbfeel free to message me privately if you'd rather15:38
zaja1kunrussellb: Routing between private and provider networks. Now all ports on my router are down15:39
russellbohhh, that's implemented now15:39
russellband tested in OpenStack CI ...15:39
russellbsupposed to work :/15:39
russellbsupports SNAT and floating IPs15:39
russellbcould be that we aren't setting port state properly for router ports15:40
russellbi need to step away for a little while15:40
zaja1kunrussellb: I'm from EPAM Systems. My team is working on system for automatic bandwidth distribution between VM's based on high-level user policy15:41
zaja1kunrussellb: It's not commercial, just investigation15:42
russellbcool, good luck to you15:42
zaja1kunThanks15:42
