| 16:29:43 | bauzas | nothing to tell about those | |
| 16:30:53 | bauzas | moving on | |
| 16:31:04 | bauzas | #topic Stable Branches | |
| 16:31:08 | bauzas | elodilles: time is yours | |
| 16:31:14 | elodilles | #info stable/yoga is unblocked openstacksdk fix has merged | |
| 16:31:22 | elodilles | #info stable/stein (and older) are blocked: grenade and other devstack based jobs fail with the same timeout issue as stable/train was previously | |
| 16:31:30 | elodilles | #info stable branch status / gate failures tracking etherpad: https://etherpad.opendev.org/p/nova-stable-branch-ci | |
| 16:31:42 | elodilles | and that is all from me | |
| 16:32:16 | bauzas | ok | |
| 16:32:39 | bauzas | thanks all for unblocking the yoga branch | |
| 16:33:37 | elodilles | yepp, thanks to openstacksdk team | |
| 16:34:04 | bauzas | ok, anything to add ? | |
| 16:34:41 | bauzas | ok, eventually the last topic then | |
| 16:34:51 | bauzas | #topic Open discussion | |
| 16:35:02 | bauzas | #link https://review.opendev.org/c/openstack/nova-specs/+/859290 Add support of Napatech SmartNICs | |
| 16:35:08 | bauzas | justas_napa: tell us more | |
| 16:35:18 | justas_napa | So maybe I'll start with a quick intro | |
| 16:35:35 | justas_napa | I'm Justas Poderys, product architect working on Napatech LinkVirtualization products | |
| 16:36:05 | justas_napa | We have been running OpenStack on our SmartNICs for over a year now, and internally support (via patches) everything from Victoria to Zed | |
| 16:36:41 | justas_napa | Going forward we'd like to enable OpenStack to work with Napa's smartnics out of the box | |
| 16:36:56 | justas_napa | for that we would like to add a VIF type corresponding to Napatech SmartNIC | |
| 16:37:08 | justas_napa | ein a simmilar fashion like Netronomes Agillio | |
| 16:37:33 | bauzas | do you work with Neutron ? | |
| 16:37:33 | justas_napa | But at the same time we do not need a new VNIC type | |
| 16:37:38 | justas_napa | Yes | |
| 16:37:46 | bauzas | so I guess you also have a neutron spec | |
| 16:38:15 | justas_napa | We have extremely small update to Neutron, but yes, we will do a Neutron spec as well | |
| 16:38:55 | bauzas | this doesn't look a lot of change for nova, right? | |
| 16:39:11 | bauzas | we already support *some* smartnic experiments | |
| 16:39:13 | justas_napa | no, I think it's less than 50 lines | |
| 16:40:13 | bauzas | justas_napa: I guess you already know about what Nova supports by the Wallaby release ? | |
| 16:40:16 | justas_napa | We will publish all changes to Nova and Os-Vif on OpenDev in the next few days | |
| 16:40:33 | justas_napa | bauzas What do you mean? | |
| 16:41:08 | bauzas | sorry, wrong release | |
| 16:41:13 | bauzas | justas_napa: I was talking of https://specs.openstack.org/openstack/nova-specs/specs/xena/implemented/sriov-smartnic-support.html | |
| 16:41:39 | bauzas | oh wait no, my bad | |
| 16:41:45 | bauzas | again, wrong spec | |
| 16:42:15 | bauzas | https://specs.openstack.org/openstack/nova-specs/specs/yoga/implemented/integration-with-off-path-network-backends.html | |
| 16:42:57 | bauzas | anyway, I just pointed out the existing specs | |
| 16:43:10 | bauzas | afaics, this is just a review ask | |
| 16:43:28 | bauzas | so, we'll review it | |
| 16:43:43 | bauzas | justas_napa: would you want to discuss your topic during the PTG ? | |
| 16:43:51 | bauzas | in case we have concerns | |
| 16:43:52 | justas_napa | Sure, I can do that | |
| 16:44:15 | bauzas | thanks | |
| 16:44:19 | bauzas | if you can't do, no worriezs | |
| 16:44:27 | justas_napa | Re: off-path networking backed - we are in the progress of integrating Intel Big Spring Canyon platform to du just that | |
| 16:44:32 | bauzas | justas_napa: and you don't need to be on the whole PTG times | |
| 16:44:57 | bauzas | justas_napa: we could just ping you when we are at the topic | |
| 16:45:01 | justas_napa | sure | |
| 16:45:15 | bauzas | thanks | |
| 16:45:30 | justas_napa | So what's the path from here: 1. We puiblish code changes and ask for review in channel? | |
| 16:45:35 | justas_napa | and then PTG? | |
| 16:45:38 | bauzas | anyone having questions or thoughts for this ? | |
| 16:45:49 | bauzas | justas_napa: indeed | |
| 16:45:56 | justas_napa | cool. | |
| 16:46:17 | bauzas | we will review your spec first, but if you have implementation changes, that would be nice | |
| 16:46:29 | bauzas | as if we have concerns, we could just look at your changes | |
| 16:46:36 | justas_napa | Yes, we have implemetation changes as well, since we are running it internally anyway | |
| 16:46:38 | gibi | I agree with bauzas | |
| 16:46:40 | bauzas | to understand what you need | |
| 16:47:21 | justas_napa | btw - is it OK to bring one more topick to PTG. Specifically, how to support Packed Ring Libvirt option (packed=on) and which project should implement that. | |
| 16:47:27 | bauzas | justas_napa: I guess you know how to depend on neutron changes ? | |
| 16:47:38 | bauzas | justas_napa: yeah, no worries | |
| 16:47:46 | bauzas | the PTG is here for discussing | |
| 16:48:08 | justas_napa | Yes, I'm aware that we need changes in Nova *and* Neutron to make this work | |
| 16:48:18 | bauzas | justas_napa: my only concern is about how to test your nova changes if you need an os-vif release | |
| 16:48:33 | bauzas | as you can't Depends-On | |
| 16:48:52 | bauzas | gibi: correct for os-vif, right? | |
| 16:49:17 | bauzas | I meant, can we depend-on os-vif patches ? | |
| 16:49:29 | gibi | I'm not sure either | |
| 16:49:49 | justas_napa | I'll put this also as TBD item for our dev team | |
| 16:49:59 | bauzas | justas_napa: do you understand about my question ? | |
| 16:50:18 | bauzas | justas_napa: if you upload three changes, each for a different repo | |
| 16:50:32 | gibi | bauzas: it depends on how the zuul job is set up. Are we testing with released os-vif lib or are we taking master all the time? | |
| 16:50:37 | bauzas | justas_napa: in general, you can depend a gerrit cvhange on another one | |
| 16:50:58 | justas_napa | Yes, I understand the issue of cross-project dependancy | |
| 16:51:14 | gibi | bauzas: if the former, then the a DNM nova patch on top of the nova series could configure zuul to use the later method + add a Depends-On to the os-vig patch | |
| 16:51:18 | justas_napa | and that our change is not atomic across the projects | |
| 16:51:24 | bauzas | justas_napa: but here, the question is that for some libraries, we maybe use a specific release and not using master | |
| 16:51:52 | bauzas | gibi: yeah, that would work | |
| 16:52:06 | bauzas | justas_napa: do you understand what gibi is explaining ? | |
| 16:52:08 | justas_napa | OK, I understand the issue, but I'm not sure I can offer a solution. | |
| 16:52:44 | bauzas | justas_napa: well, we maybe have a solution, that's the point | |
| 16:52:45 | justas_napa | One way is to use our ci/cd setup where we runn all regression tests and have control of releases of all projects | |
| 16:53:21 | bauzas | anyway, we should be discussing this in the spec | |
| 16:53:43 | bauzas | justas_napa: are you saying you could provide a third-party CI for nova/neutron ? :D | |
| 16:53:58 | bauzas | this would be lovely | |
| 16:54:16 | justas_napa | not sure what you mean 3rd party | |
| 16:54:44 | justas_napa | but we have our own ci/cd pipeline running integration tests with our changes | |
| 16:54:55 | bauzas | ok, then we'll discuss this in the spec and we can also provide you some links if you want | |
| 16:55:09 | justas_napa | to ensure we do not break anything with our OS patches | |
| 16:55:19 | bauzas | justas_napa: are you running tempest tests ? | |
| 16:55:22 | justas_napa | yes | |
| 16:55:44 | bauzas | cool, then that's something we need to discuss then | |
| 16:55:55 | bauzas | anyway, I guess we're done about your topic | |
| 16:56:01 | bauzas | we'll continue discussing | |
| 16:56:21 | justas_napa | sure, thanks for all questions and comments | |
