| 13:38:17 | stephenfin | artom: your gain is waaaay too high | |
| 13:39:20 | sean-k-mooney | artom: the zoom app auto adjust your volume | |
| 13:39:43 | sean-k-mooney | or can so maybe look at that it in the extra options via the same arror menue | |
| 13:41:20 | artom | stephenfin, but my gainz are way too low :( Stupid gyms closing | |
| 13:41:35 | stephenfin | artom: you know where the door is | |
| 13:50:50 | sean-k-mooney | artom: you are now a bit quite but that is an imporvement | |
| 13:54:06 | gibi | gmann: it is policy stuff in the nova room | |
| 13:54:11 | bauzas | gibi: patches from dansmith about the compute 5.0 API bump https://review.opendev.org/#/q/topic:queens-rpc-bump+(status:open+OR+status:merged) | |
| 13:55:00 | dansmith | bauzas: yeah | |
| 13:55:06 | gmann | gibi: 1 min joinin | |
| 13:55:08 | bauzas | gibi: the proxy dansmith told https://review.opendev.org/#/c/541005/6/nova/compute/manager.py@7750 | |
| 13:55:11 | gibi | gmann: we will discuss the policy stuff after the break at 5 minute past the hour | |
| 13:55:27 | gibi | gmann: so no rush | |
| 13:55:32 | bauzas | anyway, less a deal to write the 6.0 proxy than the 5.0 | |
| 13:55:35 | gibi | bauzas: thanks! | |
| 13:55:38 | gmann | gibi: ok | |
| 13:56:20 | bauzas | err, the 5.x proxy I mean | |

| 14:47:11 | stephenfin | kashyap: you're up next | |
| 14:49:17 | kashyap | stephenfin: Just a moment, wrapping up another thing, sorry | |
| 14:51:14 | kashyap | stephenfin: What's the topic? /me goes to check the Etherpad... | |
| 14:51:24 | stephenfin | q35 | |
| 14:52:49 | kashyap | Line-435? We already talked a bit; see line-445 on the AGREED bit | |
| 14:52:59 | kashyap | stephenfin: ^ | |
| 14:53:25 | kashyap | But sure, if there's anything else to be touched on that, can certainly speak up... | |
| 14:56:05 | kashyap | gibi: stephenfin: Has the topic flew by? Which line this whole ARM topic on? | |
| 14:56:33 | stephenfin | the previous one (line 427) | |
| 14:56:35 | kashyap | Ah, we're on line-427 currently | |
| 14:56:44 | gibi | kashyap: 427 yes | |
| 14:56:49 | kashyap | stephenfin: Yep, just see it, "virtualized architectures" | |
| 14:58:01 | dansmith | sean-k-mooney: so you could just float one DNM patch to some thing to add that queue to get one run of nova on arm yeah? | |
| 14:58:06 | dansmith | I mean, I assume we've never seen that work? | |
| 15:00:11 | sean-k-mooney | yep | |
| 15:00:30 | dansmith | yep which? can float a job or yep, we've seen it work? | |
| 15:01:13 | sean-k-mooney | you can just do a DNM patch | |
| 15:01:30 | sean-k-mooney | and yes i was looking at patches that do that previously | |
| 15:01:44 | sean-k-mooney | i think there are still a few issue they are working through | |
| 15:01:50 | dansmith | I didn't know we could do that so easily.. now I'm curious if it works as is | |
| 15:02:41 | sean-k-mooney | you just need to refecne the correct pipeline ill see if i can find the patch i was looking at before | |
| 15:14:32 | sean-k-mooney | its 8 on 3.x kernels | |
| 15:14:37 | johnthetubaguy | sean-k-mooney: ah... | |
| 15:14:41 | sean-k-mooney | becuase that si the most that vhost kernel module supports | |
| 15:14:50 | johnthetubaguy | sean-k-mooney: guest limit, or host limit, or both? | |
| 15:14:54 | johnthetubaguy | ah | |
| 15:14:56 | sean-k-mooney | in 4.X its 256 | |
| 15:15:08 | johnthetubaguy | ah, interesting, thanks | |
| 15:15:22 | sean-k-mooney | we now have a config option so you can tell nova what it is if its different | |
| 15:15:32 | kashyap | gibi: I need to drop to run a quick errand, afraid | |
| 15:15:46 | gibi | kashyap: do you have other topics on the etherpad? | |
| 15:16:02 | kashyap | gibi: Not that I know of | |
| 15:16:02 | gibi | I don't see any | |
| 15:16:08 | gibi | OK. thanks for joining | |
| 15:16:53 | kashyap | I'm curious to hear stephenfin's topic of "documentation is awful" (line-474) - please take some notes on it on the Etherpad :) | |
| 15:17:39 | gibi | kashyap: ack | |
| 15:30:23 | sean-k-mooney | https://docs.openstack.org/nova/latest/configuration/config.html#filter_scheduler.max_io_ops_per_host | |
| 15:56:20 | melwitt | sean-k-mooney: just curious, how can you know there's not enough swap configured before any instances are booted so you know the flavor? | |
| 15:56:29 | CeeMac | hi sean-k-mooney and melwitt ; regarding or chat yesterday around shelving, we've done some testing today and it would appear that even in shelved_offloaded state an instance is accumulating usage and the resources still appear allocated in the project quota | |
| 15:57:09 | CeeMac | im back to being perplexed | |
| 15:57:24 | melwitt | CeeMac: oh... this is sounding familiar :( | |
| 15:57:43 | CeeMac | well, that doesnt sound good :/ | |
| 15:58:06 | CeeMac | i'm running rocky btw | |
| 15:58:51 | melwitt | long ago, when the shelve API was added I am recalling that we don't release quota while instance is shelved. but I didn't realize that would cause it to count as the simple tenant usage. but it makes sense that it would | |
| 15:59:27 | melwitt | the reasoning behind that decision was, not to let the user ever be in a position where they cannot unshelve for lack of quota | |
| 16:00:46 | CeeMac | yeah, i was actually having that conversation with my colleagues around implications to consider when shelving | |
| 16:01:40 | CeeMac | i guess, at least in the way I'm ingesting the data, it depends on how horizon is building its usage information for Admin | Overview | Usage summary | |
| 16:03:56 | CeeMac | let me see if I can pull some data from the openstack cli | |
| 16:16:53 | CeeMac | apparently I cant /fail | |
| 16:17:24 | melwitt | CeeMac: trying to get the same data that horizon shows you? | |
| 16:17:35 | CeeMac | yeah for the instances specifically | |
| 16:17:42 | CeeMac | i see the project usage in general | |
| 16:17:57 | CeeMac | although it wont show any details for the admin project | |
| 16:18:09 | CeeMac | which is odd (maybe) | |
| 16:18:20 | CeeMac | openstack usage show/list I've tried | |
| 16:18:45 | melwitt | ok I was about to ask, that should be the right command | |
| 16:18:52 | CeeMac | I could have sworn i'd seen something about instance usage when I was reading up yesterday, but I can't find it now if I did | |
| 16:19:02 | CeeMac | yeah, list only has some projects | |
| 16:19:10 | CeeMac | i'll maybe try with a different rc file, one sec | |
| 16:22:58 | CeeMac | yeah, thats not helped. I'll retry the test in demo project as I can see that | |
| 16:23:50 | CeeMac | although openstack usage show only gives the totals, not per instance | |
| 16:29:02 | CeeMac | ok I'm stumped | |
| 16:29:27 | melwitt | I need to look a deeper at it because obviously horizon is getting it somehow, to be able to tell you how to do it with the cli | |
| 16:31:11 | CeeMac | no worries | |
| 16:32:43 | CeeMac | i think maybe the actual api is more capable than what is implemented in the cli just now, from what I remember seeing reading through api-ref last night | |
| 16:32:55 | CeeMac | direct call api stuff is a bit beyond me at the moment though | |
| 16:35:10 | gmann | stephenfin: this one i was talking, i added index page for tempest plugins having some link on tempest do "Stable Branch * Policy" - https://docs.openstack.org/tempest/latest/plugins/index.html | |
| 17:02:39 | dansmith | stephenfin: your picture is dark so I can't tell if you were receiving my good-natured jabbing properly | |
| 17:03:02 | stephenfin | Heh, all good. See Zoom chat | |
| 17:03:24 | dansmith | ah heh yeah | |
| 17:23:30 | sean-k-mooney | melwitt: sorry didnt see that till now. total_ram * allocation ratio - reserved should <= total_ram + swap | |
| 17:24:02 | sean-k-mooney | so that would be the init_host check | |
| 17:24:24 | sean-k-mooney | the per vm check is if i add up the MEMORY_MB for all vms on this host is it larger then total ram | |
| 17:24:28 | sean-k-mooney | if so warn | |
| 17:25:00 | sean-k-mooney | the less agressive warning would be to warn on total_ram + swap | |
| 17:25:38 | sean-k-mooney | instead of > then total ram but once your are over total ram you are in OOM killer terrorty | |
| 17:26:58 | melwitt | sean-k-mooney: ah I see, thanks | |
| 17:27:23 | sean-k-mooney | melwitt: do you rememebr the nova bug for that transport thing i borught up at the end | |
| 17:27:42 | sean-k-mooney | melwitt: i remember debuging it with you at the time | |
| 17:27:52 | melwitt | yeah vaguely | |
| 17:28:01 | melwitt | it's the mandatory flag for oslo messaging | |
