| darrena092 | Hey - I asked in here yesterday but had to go. I'm having a problem where I'm creating a couple of ports on a bridge that use vxlan to tunnel packets to other hosts, but when I add more than one port connected to a vxlan iface I lose all connectivity. | 07:08 |
|---|---|---|
| darrena092 | No idea what's going on at this point. Anyone ever seen that before? | 07:08 |

| mmichelson | Hi everyone! | 17:20 |
| mmichelson | Sorry I got sidetracked | 17:20 |
| *** zhouhan_ has quit IRC | 17:20 | |
| _lore_ | hi all | 17:20 |
| mmichelson | Anyone remember what we're calling this meeting for the meeting bot? | 17:20 |
| numans | mmichelson, Hi | 17:20 |
| numans | Hi | 17:20 |
| *** zhouhan has joined #openvswitch | 17:20 | |
| numans | mmichelson, one sec | 17:20 |
| zhouhan | morning | 17:20 |
| mmichelson | #startmeeting ovn-community-development-discussion | 17:20 |
| openstack | Meeting started Thu Apr 16 17:20:44 2020 UTC and is due to finish in 60 minutes. The chair is mmichelson. Information about MeetBot at http://wiki.debian.org/MeetBot. | 17:20 |
| openstack | Useful Commands: #action #agreed #help #info #idea #link #topic #startvote. | 17:20 |
| openstack | The meeting name has been set to 'ovn_community_development_discussion' | 17:20 |
| numans | cool got it | 17:21 |
| mmichelson | Turns out if I press up enough times I can get back to the previous time I started the meeting | 17:21 |
| mmichelson | Anyways, it's meeting time. | 17:21 |
| flaviof | lol. nice | 17:21 |
| mmichelson | So who'd like to go first this week? | 17:21 |
| flaviof | I suppose I can go | 17:22 |
| flaviof | I spent some time looking at the changes that Ankur did for NAT external port range and proposed some follow ups | 17:23 |
| flaviof | #link https://patchwork.ozlabs.org/project/openvswitch/cover/20200415221006.22628-1-flavio@flaviof.com/ port range folow up in need of review | 17:23 |
| *** aginwala has joined #openvswitch | 17:23 | |
| flaviof | My goal was actually to see if we could leverage this functionality to do something a little different, which in openstack is called port forwarding. | 17:24 |
| flaviof | In that case the same one external_ip can be mapped to multiple internal ips, based on the (non-overlapping) port range | 17:24 |
| flaviof | It seems initially that is not possoble bc there can only be one port mapping per external_ip. | 17:25 |
| numans | flaviof, Thanks for the patch. I'll take a look. | 17:25 |
| flaviof | I would like to see if changes on ovn schema can be done so that the external ip is not the index, but the tuple external_ip and port_range are | 17:25 |
| numans | Regarding port forwarding can't we use ovn load balancer feature ? | 17:25 |
| flaviof | numans: np! | 17:25 |
| flaviof | that is all from me | 17:26 |
| numans | I think probably it can be | 17:26 |
| flaviof | numans: oh that would be awesome! | 17:26 |
| numans | I'd suggest to explore if its possible | 17:26 |
| mmichelson | I'll have a look at your patch, too flaviof | 17:26 |
| mmichelson | So who'd like to go next? | 17:27 |
| numans | I can go next | 17:27 |
| flaviof | numans: yes, ovn load balancer feature could be used. | 17:27 |
| flaviof | but we were hoping for something simpler | 17:27 |
| flaviof | anywyas, we can talk more on that later. pls proceed | 17:27 |
| numans | flaviof, sure. Thansk | 17:28 |
| numans | I've been working on the I-P enhancement patches | 17:28 |
| numans | I have now the patches ready which handles runtime data changes. And the initial tests show promising improvements | 17:28 |
| numans | I'm hoping to submit the patches for review tomorrow | 17:28 |
| numans | I also did a couple of reviews | 17:29 |
| zhouhan | numans: looking forward to it! | 17:29 |
| numans | I've the patches here at the moment - https://github.com/numansiddique/ovn/commits/IP_FullIP/v3/p10 | 17:29 |
| numans | That's it from me. | 17:30 |
| *** ryzhyk has joined #openvswitch | 17:30 | |
| mmichelson | OK cool. Who'd like to go next? | 17:30 |
| numans | Forgot to mention that Anil worked with me on this. | 17:30 |
| flaviof | avishnoi? | 17:31 |
| numans | flaviof, No. Venkata Anil | 17:31 |
| flaviof | ack. Both of them are awesome. ;) | 17:31 |
| zhouhan | I can go next | 17:31 |
| zhouhan | I did some review for ovn-scale-test. Had some comment on dceara's PR | 17:32 |
| zhouhan | We deployed full interconnection in prod between 3 AZs in ebay. No major issues so far, but I found debugging ECMP is kind of tricky because of the "group" action | 17:33 |
| zhouhan | that's it from me | 17:34 |
| numans | zhouhan, that's good to hear | 17:34 |
| flaviof | +1 | 17:34 |
| zhouhan | The route advertisement feature was really helpful, otherwise I would have to manually configure thoussands of routes | 17:35 |
| mmichelson | zhouhan, about how many nodes in each AZ? | 17:35 |
| _lore_ | zhouhan: regarding ovn-scale-test I added something similar to openshift networkpolicy | 17:35 |
| *** mmirecki has quit IRC | 17:35 | |
| zhouhan | mmichelson: the number of nodes is around 1k, as we shared before | 17:35 |
| zhouhan | for each AZ | 17:35 |
| zhouhan | _lore_: oh, I merged your last PR, thanks! Is this a new one? | 17:36 |
| *** ktraynor has quit IRC | 17:36 | |
| *** ktraynor has joined #openvswitch | 17:36 | |
| mmichelson | zhouhan, OK | 17:37 |
| mmichelson | OK, so who'd like to go next? | 17:37 |
| ihrachys | i can do next | 17:37 |
| *** rcernin has quit IRC | 17:37 | |
| mmichelson | sure ihrachys | 17:37 |
| ihrachys | i've been working on multiple localnet ports for openstack peeps (their routed network feature) | 17:38 |
| _lore_ | zhouhan: nope | 17:38 |
| ihrachys | #link https://patchwork.ozlabs.org/project/openvswitch/patch/20200415014412.449850-1-ihrachys@redhat.com/ | 17:38 |
| _lore_ | it is another one not posted yet | 17:38 |
| ihrachys | happy to report it seems to work, I've asked Maciej from openstack to validate in their env and it works fine. | 17:38 |
| _lore_ | I was waiting the pending one to be merged | 17:39 |
| _lore_ | I will post it soon | 17:39 |
| mmichelson | ihrachys, that's good news! | 17:39 |
| ihrachys | there are still some issues to handle (logs still flooded with messages about missing bridge mappings; plus the e-w routing between vlan tagged networks issue Dumitru mentioned at one point) | 17:39 |
| ihrachys | so it's RFC for now in case someone wants to take an early look | 17:39 |
| zhouhan | ihrachys: multiple localnet ports for one lswitch? Or something else? | 17:39 |
| ihrachys | yes same switch, multiple localnet ports; assumption being a single port is actually mapped per chassis | 17:40 |
| ihrachys | then routing between l2 segments is implemented by fabric | 17:40 |
| *** ktraynor has quit IRC | 17:40 | |
| ihrachys | there's some bg at https://mail.openvswitch.org/pipermail/ovs-discuss/2020-March/049876.html | 17:41 |
| ihrachys | that's it from me | 17:41 |
| *** ktraynor has joined #openvswitch | 17:41 | |
| flaviof | really cool ihrachys++ I will take a look too | 17:41 |
| zhouhan | ihrachys: thanks for the pointer, I will study it. | 17:41 |
| mmichelson | OK so anyone else want to give an update? | 17:42 |
| _lore_ | I can go very fast | 17:43 |
| _lore_ | this week I worked on iPXE support in OVN | 17:43 |
| _lore_ | I shared a path to OSP folks and I am waiting for feedbacks, I will post it as soon as I got some news | 17:43 |
| _lore_ | moreover I continued working on ovn-scale-test | 17:44 |
| *** links has quit IRC | 17:44 | |
| _lore_ | that all from my side | 17:45 |
| _lore_ | *that's | 17:46 |
| *** anilvenkata has joined #openvswitch | 17:46 | |
| mmichelson | OK, anybody else? | 17:47 |
| numans | Just a note - Dumitru moved the ovn-scale-testing code to his personal repo - https://github.com/dceara/ovn-heater | 17:48 |
| numans | we use this for our internal scale testing. | 17:48 |
| numans | in case someone wants to give a try :) | 17:48 |
| flaviof | I like the name! ;) | 17:48 |
| dceara | numans, thanks for bringing it up :) | 17:48 |
| dceara | zhouhan, thanks for the ovn-scale-test reviews! | 17:49 |
| numans | dceara, I thought you're not joining today | 17:49 |
| dceara | numans, managed to put the kids to bed early ;) | 17:49 |
| mmichelson | dceara, did you want to give an update? | 17:50 |
| dceara | mmichelson, just a short update | 17:50 |
| zhouhan | numans: dceara what does it mean - moved to personal repo? Is it because of my slow code review :( ? | 17:50 |
| numans | zhouhan, no no. that's a different project :) | 17:51 |
| dceara | regarding the scale testing code, it's just temporarily under my github account until we figure out if it's useful for the community and then we can decide if we move it somewhere else (maybe directly under ovn-org or as part of ovn-scale-test) | 17:51 |
| zhouhan | dceara: would hope it is in ovn-scale-test, if it is not totally different | 17:52 |
| dceara | zhouhan, no, definitely not. It's just that we need to provision quite a lot of infra to run the scale tests on our physical lab. This is what ovn-heater does: provision & run tests & collect results | 17:52 |
| mmichelson | ovn-heater glues ovn-scale-test, rally, browbeat, ovn, ovs, and ovn-fake-multinode together into something useful | 17:52 |
| dceara | zhouhan, right now it uses ovn-scale-test. I'm still not sure if it should be part of it or just a separate repo but we can discuss | 17:52 |
| mmichelson | And makes it super easy to set up and run scale tests. | 17:52 |
| zhouhan | dceara: I think that is the same goal as ovn-scale-test, which of course has lots of space for improvement :) | 17:52 |
| flaviof | ovn-heater: the glue gun of ovn scaling tests! ;) | 17:53 |
| dceara | zhouhan, that's definitely one option: to integrate it completely in ovn-scale-test | 17:53 |
| dceara | zhouhan, that's why I said "temporarily" on my github account. It still needs work and a clear direction. | 17:54 |
| zhouhan | awesome! | 17:54 |
| dceara | mmichelson, that was all from me today, thanks! | 17:54 |
| mmichelson | dceara, excellent | 17:54 |
| mmichelson | I don't have an update of my own to give. I've mostly been doing internal things (scripts to mess with bugzilla, bug triage, etc.) so nothing to say from me here. | 17:55 |
| mmichelson | Soooo I guess that's it. | 17:55 |
