| 11:48:02 | mkarpiarz | 1. Store the list of available mediated devices in some global structure. | |
| 11:49:54 | mkarpiarz | 2. Let the instance fail in launch and return back to spawn(), so it can check available devices again. | |
| 11:51:52 | mkarpiarz | Any other ideas? | |

| 12:47:47 | tacco | hi there.. i have a issue with a redeployed hypervisor.. after deployment i see a "ResourceProviderCreationFailed: Failed to create resource provider" error when trying to start nova or migrating a instance to this hypervisor https://pastebin.com/zMHUUYEW | |
| 12:55:49 | yaawang | hi, could anyone please take a review on https://review.openstack.org/#/c/637834/, this a patch about libvirt cpu models select :-) | |

| 13:33:10 | artom | sean-k-mooney, wait, we can have nested virt in nodepool now? mnaser, is vexxhost doing that now? | |
| 13:33:48 | mnaser | artom: we’re doing it but | |
| 13:33:53 | sean-k-mooney | artom: technically. the ci jobs will still try to disable it but we can renable it | |
| 13:33:59 | mnaser | I’m trying not to broadcast it too much | |
| 13:34:15 | artom | mnaser, oops, sorry :) | |
| 13:34:22 | mnaser | I want the jobs that use it are jobs that need to use it, not.. just do it can be faster | |
| 13:34:41 | mnaser | So Magnum is a case where it was useful and that’s why we added it | |
| 13:34:41 | artom | mnaser, well, NUMA live migration *needs* to use it :) | |
| 13:34:44 | sean-k-mooney | mnaser: i brought it up in the context of testing nuam aware live migration | |
| 13:34:55 | mnaser | Yeah then I’d be supportive of it | |
| 13:35:00 | artom | mnaser, sweet! | |
| 13:35:14 | sean-k-mooney | artom: as i said it would have to be non voting however | |
| 13:35:28 | yonglihe | mriedem: alex_xu: https://review.openstack.org/621474 updated per all comments. I have to have rest. have a good one everyone. | |
| 13:35:29 | artom | sean-k-mooney, yeah that's fine, we have to start somewhere | |
| 13:35:43 | artom | Even just being able to trigger a job manually that posts publicly would be a great first step | |
| 13:36:20 | sean-k-mooney | artom: if ovh/packet reenable it in the future we might be able to make it voting eventually | |
| 13:36:30 | artom | sean-k-mooney, baby steps :) | |
| 13:36:32 | sean-k-mooney | artom: well you could start by adding it to the experimental pipeline | |
| 13:36:52 | sean-k-mooney | that requires a comment ot trigger it | |
| 13:36:58 | artom | sean-k-mooney, wouldn't I have to start by moving whitebox to the openstack namespace? | |
| 13:37:08 | sean-k-mooney | yes | |
| 13:37:15 | sean-k-mooney | i ment after that | |
| 13:37:27 | sean-k-mooney | and you know after we write all the tests | |
| 13:37:41 | artom | Hey, I have some written already :) | |
| 13:38:04 | sean-k-mooney | did you look at the list i gave in the email | |
| 13:38:17 | artom | Yeah | |
| 13:38:19 | sean-k-mooney | feel free to automate those while i test them | |
| 13:38:52 | artom | sean-k-mooney, that'll kinda depend on whether the absence of func tests is a blocker for mriedem | |
| 13:39:04 | artom | If it is, those take priority before FF | |
| 13:39:15 | sean-k-mooney | yep | |
| 13:39:16 | artom | Other than that timing issue, I'll happily hax those up | |
| 13:43:03 | sean-k-mooney | artom: once you get the first functional test working i suspect the rest will be fairly staight forward | |
| 13:44:05 | sean-k-mooney | if you can add the functional test as a follow up that will reduce churn and make my testing eaisier | |
| 13:44:42 | artom | sean-k-mooney, yep, good idea. I can start with the tests in a new patch on top, and we can squash later | |
| 13:45:04 | sean-k-mooney | yep or even just keep it on top | |
| 13:45:46 | sean-k-mooney | squashing them to keep them with the feature code is nice but i dont think its required | |
| 14:00:24 | sean-k-mooney | mnaser: by they way do you use kvm on ubuntu 18.04 for vexhost? | |
| 14:00:33 | mnaser | sean-k-mooney: centos 7 | |
| 14:00:38 | sean-k-mooney | ah ok | |
| 14:00:46 | mnaser | but we've managed to get the perfect combo for functional nested virt | |
| 14:00:51 | mnaser | thanks a lot to the kata containers folks | |
| 14:00:57 | sean-k-mooney | there is a bug in the ubunut 18.04 kernel that breaks nested virt | |
| 14:01:18 | sean-k-mooney | i had to replace mine with the mainline 4.20 kernel to fix issues | |
| 14:01:19 | mnaser | yeah our ci is worked out pretty often both by magnum and kata and their nested virt has been super stable | |
| 14:02:46 | sean-k-mooney | ya i went with ubuntu 18.04 because kolla-ansibel source deploys work better on ubuntu then centos in my previos experience | |
| 14:03:02 | sean-k-mooney | mnaser: do ye use openstack ansible for your production installation | |
| 14:03:07 | mnaser | sean-k-mooney: yeah | |
| 14:03:56 | sean-k-mooney | i must get around to checking that out at some point but since its working im not going to touch it untill i need to upgrade :) | |
| 14:10:04 | mdbooth | bauzas: Do you recall why rebuild is forced to be on the same host? Is it just because the way rebuild is written doesn't allow for a migration, or is it fundamental to the intent of rebuild? Or some other reason? | |
| 14:12:10 | sean-k-mooney | mdbooth: why would a rebuild ever need to migrate if the image does not change | |
| 14:12:21 | sean-k-mooney | if the image does change we hit the schulder | |
| 14:12:25 | mdbooth | bauzas: I ask because I was looking at the attach/detach root volume patches. They look fine, but shelve/unshelve is just distasteful, so having it as the only available option seems undesirable. Reading the original spec, it sounds to me like they want to rebuild on a different host... | |
| 14:12:30 | mdbooth | Which is an evacuate# | |
| 14:12:42 | mdbooth | Evacuate with a different root volume. | |
| 14:12:43 | mdbooth | Hmm | |
| 14:13:06 | mnaser | sean-k-mooney: be happy to help you get setup on OSA | |
| 14:13:19 | mdbooth | sean-k-mooney: Yes, we hit the scheduler but constrain it to return the original host or return NoValidHost | |
| 14:14:01 | mdbooth | Rebuild on a different host with a different root volume... | |
| 14:14:02 | sean-k-mooney | mnaser: its more just i have not taken the time to try it out. i learn how kolla ansible worked a few years ago and it served well enough for my personal needs | |
| 14:14:20 | sean-k-mooney | mdbooth: ah ok | |
| 14:14:30 | bauzas | mdbooth: because it doesn't ask for other resources, just for an image | |
| 14:14:43 | bauzas | unless you evacuate :) | |
| 14:15:05 | mdbooth | bauzas: Given that evacuate exists, I'm guessing most of this is already wired up. | |
| 14:15:55 | bauzas | yeah, that's actually the change in between evacuate and rebuild | |
| 14:16:09 | mdbooth | In fact: cold migrate with a different root volume. | |
| 14:16:10 | bauzas | evacuate is just the same rebuild path but with a different API action :) | |
| 14:16:18 | bauzas | hum no | |
| 14:16:23 | bauzas | cold migrate != evacuate | |
| 14:16:32 | bauzas | evacuate == rebuild(different_host) | |
| 14:16:47 | mdbooth | bauzas: Hmm, no. It doesn't consider a change of image. | |
| 14:17:14 | mdbooth | But I was thinking that you might have a root volume and ephemeral disks, in which case you might want to migrate them. | |
| 14:19:38 | mdbooth | bauzas: So, going back to the original question, why do we go to lengths to ensure that rebuild doesn't change host? | |
| 14:20:04 | bauzas | mdbooth: I'm not the rebuild specialist | |
| 14:20:30 | bauzas | some others hitted so many times issues with rebuild that they're more knowledgable than me, like... mriedem ? :) | |
| 14:20:38 | mdbooth | bauzas: Ah, sorry. I pinged you because you were co-author in a patch which added this constraint. | |
| 14:20:47 | mdbooth | mriedem was the other author. | |
| 14:20:52 | bauzas | knowledgable * (not sure it's a word) | |
| 14:21:44 | mdbooth | bauzas: Yeah, it's a word. Pretty sure that's not how you spell it, but I wouldn't have called you on it as I'm not 100% sure myself ;) | |
| 14:23:03 | mriedem | what is the question? | |
| 14:23:12 | mriedem | why doesn't rebuild migrate? | |
| 14:23:21 | mriedem | why do we validate the image against the scheduler when it changes? | |
| 14:23:28 | mriedem | because build is on the same host | |
| 14:23:37 | mriedem | why? because that's the way it originated | |
