#openstack-nova - 2018-12-06
18:55:36 spatel Here i file bug https://bugs.launchpad.net/horizon/+bug/1807251
18:55:56 cdent I imagine there is.a super upper ontology of assery
18:58:52 sean-k-mooney spatel: that is strange
18:59:16 spatel definitely bug or may be some DB cleanup stuff?
18:59:17 sean-k-mooney even teh other things like cpu hours are way out
18:59:27 spatel exactly
19:00:02 sean-k-mooney are they showing the same time period
19:00:03 sean-k-mooney 2018-11-08 to 2018-12-07
19:01:05 sean-k-mooney it looks like the cli is defaulting to the last month but maybe horizon has a differnt default
19:01:13 spatel on Horizon dates are default set to 2018-12-05 to 2018-12-06
19:01:21 spatel 24 hours period
19:01:43 sean-k-mooney that does not explain how horrizon is showing more usage
19:01:53 sean-k-mooney in fact it makes it less likely..
19:02:29 spatel hmm
19:02:35 sean-k-mooney so ya sorry i cant really help more then that
19:06:00 spatel don't worry it was good help to understand that i am not crazy...
19:06:19 spatel i thought i didn't understand or missing something but after you confirm it seems bug
19:06:26 spatel anyway i have opened ticket so lets see
19:07:32 cfriesen sean-k-mooney: do you know if anyone has ever looked at setting IRQ affinity for PCI devices? (would only really make sense for the "dedicated" case)
19:07:52 sean-k-mooney i did like 4 years ago
19:08:28 sean-k-mooney thre are two field of tought on this either user irq blanace or whatever to afinities all irq away form the cores used by vms
19:09:00 cfriesen sean-k-mooney: I'm talking about for PCI-passthrough, setting the affinity to the pCPUs used by the guest
19:09:02 sean-k-mooney or dynamicaly affinities irqs for a vf to the vm cpus
19:10:19 sean-k-mooney ya i was asked to make that change a few years ago and got push back rom redhat folks on the libvirt team.
19:10:26 sean-k-mooney let me see if i can find that.
19:21:18 sean-k-mooney hum i must have been an intel only bug which aparently i cant see
19:28:02 openstack sean-k-mooney: Error: Error getting bugzilla.redhat.com bug #1135668: NotPermitted
19:28:02 sean-k-mooney cfriesen: i assume you cant see https://bugzilla.redhat.com/show_bug.cgi?id=1135668
19:29:10 cfriesen sean-k-mooney: nope. :)
19:29:17 sean-k-mooney cfriesen: when we rant this by the libvirt people they were concerned that affinities the interups to the vm cores could cause alot of guest VM_exits to serivce the interupts
19:29:52 cfriesen sean-k-mooney: enough to outweigh the preloading of the cache?
19:30:39 openstackgerrit Matt Riedemann proposed openstack/nova master: DRY up SchedulerReportClient init https://review.openstack.org/623247
19:30:39 openstackgerrit Matt Riedemann proposed openstack/nova master: Only construct SchedulerReportClient on first access from API https://review.openstack.org/623246
19:31:35 sean-k-mooney so this was created on 2014-08-29 so my memory is a little fuzzy but they wanted use to show that it would out way that overhead and at the time we did not have the capsity to test it in an openstack environmnt to messuer it
19:31:55 sean-k-mooney so it was drop becasue of lack of evidence to show ti was a usefull feature to add to libvirt
19:32:15 sean-k-mooney we abandonded our nova work as a result
19:32:45 sean-k-mooney what everyone did agree on is that affizing to the same numa node was a good idea
19:33:16 cfriesen okay, thanks
19:33:31 sean-k-mooney thinking about it now i think affinitizing to the emuplator thread or thread poll in isolate/shared mode might be better the to the vcpus
19:35:10 sean-k-mooney cfriesen: did you do any testing out of interest?
19:35:36 sean-k-mooney cfriesen: hehe oh look here is my orginal mail https://www.mail-archive.com/libvir-list@redhat.com/msg100707.html
19:36:05 cfriesen I'm actually not sure. we had an in-house nova commit to enable pinning, but I wasn't the one that implemented it. Kind of curious myself if they tested it. :)
19:36:33 sean-k-mooney wow that was before i got the intel leagal email footer remove form my acount that was along time ago
19:56:44 coreycb tobias-urdin: we have a placement package now
19:57:03 coreycb tobias-urdin: just fyi, i know you were asking for it a little while back
20:11:45 lyarwood coreycb: link? I'll wire that up in my puppet changes tomorrow
20:12:10 openstackgerrit Chris Dent proposed openstack/nova master: Correct lower-constraints.txt and the related tox job https://review.openstack.org/622972
20:15:56 mriedem aspiers: will config drive work with sev guests?
20:16:04 mriedem sean asked in the spec review but i didn't see an answer
20:17:18 coreycb lyarwood: placement-api is the package name
20:25:48 mriedem aspiers: comments inline https://review.openstack.org/#/c/609779/ but +1
20:26:59 lyarwood coreycb: https://review.openstack.org/623306 - loads of assumptions about the package but I'll take another look in the morning
20:29:42 coreycb lyarwood: that generally looks good to me. let me know how it goes and thanks for testing.
20:38:14 openstackgerrit Matt Riedemann proposed openstack/nova master: Ignore MoxStubout deprecation warnings https://review.openstack.org/623309
20:38:15 mriedem let's do this ^
20:49:17 artom The hell, how do I dn sync cell1?
20:50:29 artom *db
20:50:43 melwitt nova meeting in 10 minutes
20:55:22 coreycb mriedem: hi, just a friendly ping to see if you can review this when you get a chance. looks like it has a +1 from another core dev: https://review.openstack.org/#/c/579004/
20:55:23 artom Ah, just pass --config-file cell1.conf to nova-manage
20:55:26 artom (from https://docs.openstack.org/nova/pike/cli/nova-manage.html)
20:58:24 mriedem coreycb: it's got the star but yeah i need to spend some time on it
20:59:28 coreycb mriedem: ok thanks in advance
21:02:44 Sundar I'd appreciate if somebody can answer the question in: https://ask.openstack.org/en/question/117509/unable-to-update-rc-inventory-in-resource-provider/ . If openstack-discuss is a better place to pose that question, I'll bring it there.
21:22:32 dansmith Sundar: pretty sure your url there is wrong
21:23:09 dansmith Sundar: you might want to look at the nova functional tests or the placement gabbit
21:24:08 dansmith Sundar: you're trying to put inventory on a provider right?
21:24:09 dansmith Sundar: https://developer.openstack.org/api-ref/placement/#update-resource-provider-inventories
21:24:52 dansmith I guess I'm wrong and the url is right, but I surely didn't think that was how that worked
21:25:02 dansmith because: atomicity
21:25:42 dansmith ah right you can PUT on the provider itself do do multiples
21:26:23 dansmith https://developer.openstack.org/api-ref/placement/?expanded=update-resource-provider-inventories-detail#update-resource-provider-inventories
21:26:43 mriedem or just, openstack --debug resource provider inventory set ...
21:26:55 mriedem https://docs.openstack.org/osc-placement/latest/index.html
21:27:18 dansmith mriedem: yeah, that's how I'd be doing it.. I figured he had some reason for doing it with curl
21:35:57 Sundar dansmith: mriedem: I use curl by default. And I thought whatever works via openstack commands should also work via curl. Apparently not. :) Anyways, the openstack command worked. Thanks!
21:36:31 dansmith Sundar: of course you _can_ use curl, but you get into situations like you're in now where you get back a 400 because you typo'd something and it's hard to tell what that is :)
21:36:33 mriedem it should work via curl
21:36:40 mriedem right
21:36:58 dansmith it's why we don't all write in machine language in 2018
21:37:36 Sundar Curl tends to be much faster than openstack commands, in my experience.
21:38:02 mriedem it fails very fast yes :)
21:38:02 dansmith Sundar: you asked on Nov 21 and got an answer on Dec 6.. seems like pretty terrible performance to me :)
21:38:30 efried_cya_jan Sundar: I just looked at the gabbits, and it appears as though in order for that PUT to work, the inventory of that resource class has to exist already.
21:38:43 efried_cya_jan I.e. the PUT is designed to modify an existing inventory, not create a new one.
21:38:44 mriedem PUT generally means updating something that exists
21:38:55 efried_cya_jan I think edleafe might disagree on that one
21:39:00 Sundar dansmith: I had a very long retry setting :)
21:39:14 efried_cya_jan Sundar: let me get you a link to the gabbit...
21:39:24 edleafe efried_cya_jan: damn straight
21:39:45 edleafe PUT replaces
21:40:00 efried_cya_jan Sundar: https://github.com/openstack/placement/blob/master/placement/tests/functional/gabbits/inventory.yaml#L234
21:40:11 mriedem gaudenz: you need to set this to true in the devstack-plugin-ceph job https://github.com/openstack/tempest/blob/b62baf7c16d4609ea92e2ffc974e2f3a0b1cec80/tempest/config.py#L896
21:40:11 efried_cya_jan edleafe: In which case this operation is busted :(
21:40:18 mriedem gaudenz: and make that patch depend on the nova chnage
21:40:21 mriedem and then you should be good
21:41:04 mriedem gaudenz: right in here https://github.com/openstack/devstack-plugin-ceph/blob/39de6df04130cf2f221fb5ba2a9b5ff597de332a/devstack/plugin.sh#L98
21:41:29 efried_cya_jan edleafe, cdent: It appears we're missing a gabbi test for a successful PUT /rps/{u}/inventories/{rc}
21:41:38 efried_cya_jan ...or it's not in that file
21:41:53 mriedem gaudenz: commented in the nova change on the steps
