20:21:53 efried yeah, that was my concern, but it's between that rock and the hard place of trying to anticipate $world-with-cyborg before that's a thing.
20:22:07 edmondsw yep
20:22:20 edmondsw I see many interesting PTG conversations in your future...
20:22:43 edmondsw wish I could be there

21:32:59 mnaser fun fact
21:33:02 mnaser console logs disappear on live migration
21:33:19 mnaser themoreyouknow.gif
21:47:37 mriedem you're welcome
21:53:59 mriedem so i thought artom changed direction on numa-aware live migration https://review.openstack.org/#/c/599587/ ?
21:54:04 mriedem because the re-proposed spec is the same old thing
21:54:21 mriedem stephenfin: ^
21:54:31 mriedem btw, GET /artom is a 404
21:54:33 mriedem wtf?

07:08:44 artom Actually, sahid, if you're awake already, you might know this. Can NUMA resources be claimed without using a MoveClaim context?
07:08:51 openstackgerrit Chen proposed openstack/nova master: doc: update info for hypervisors https://review.openstack.org/599554
07:10:29 sahid artom: not sure what you mean? i thnk we have two ways to claim resources but you can implement a new one if necessary
07:11:20 artom sahid, so, for cold migration for instance, there's code in the conductor that essentially says, "with rt.cold_migration_claim: <do cold migration>"
07:11:35 artom And IIUC this claim context is how resources are claimed on the destination node
07:12:01 artom Is there a less opaque way of doing, for example by calling something like rt.claim_these_resources_on_the_compute_host?
07:12:28 artom I'm essentially trying to avoid having to understand claim contexts :D
07:15:00 sahid artom: well... i did not have yet finish my coffe but i would say, you will have to reuse moveclaim that to avoid rewriting everything,
07:15:24 artom sahid, aha, thanks! That's... what I was afraid of :(
07:16:45 sahid artom there is nothing so complicted in moveclaim, basically we just create a migration object context and update resources on destination host based on the instance that we are migrating
07:17:22 artom sahid, heh, you keep saying that, and I just can never bring myself to go through that code and understand what's going on and what else it affects
07:17:40 artom sahid, maybe a bjns when you have time so you can bring me up to speed
07:18:00 sahid what is blocking you?
07:18:19 artom Besides my own stupidity and laziness? ;)
07:18:38 sahid ahahah :)
07:19:35 artom So, the context is, I'm updating the live migration spec for Stein, and I was pinning my hopes on placement to claim resources on the dest
07:20:31 artom But! Placement is only qualitative - ie, you can say I'm claiming 2 NUMA nodes, but you can't say I'm claiming NUMA node 0 and 3, and pinning CPUs 1-4 and 4-8
07:20:52 artom So we'll need claims on the compute node regardless, even in the distance future when placement starts doing NUMA for us
07:21:33 artom Because for NUMA we need to know *which* specific resources are being claimed, not just how many
07:21:49 artom The mellanox guys want to do live migration with SRIOV, and they have the same problem
07:22:59 artom I'll continue updating the spec, and them, if you're willing, come back with a more concrete list of questions than just "HALP!!11"
07:23:37 sahid so basically i would say first you will have to update hardware.fit_instance_to_host() to work with placement
07:24:55 sahid well actually i have some doubt you can achieve that work with placement right now
07:25:13 artom Well, the conversion of hardware/resource_tracker to use placement will come later, for now there isn't even a spec for Stein for NUMA RPs in placement (though Sylvain did have one proposed for Rocky)
07:25:29 artom sahid, yeah, it's for later, the pieces aren't in placement yet
07:25:40 sahid ok so i would say forget about placement, we will be able to update our code at time
07:25:42 artom I need to bite the bullet and work with the claim context
07:26:02 sahid yes you should make this working for claim using resource_tracker
07:26:30 artom Which I've been desperately trying to avoid, but I don't think there's a way around it :(

16:15:42 mriedem johnthetubaguy: you should review this spec https://review.openstack.org/#/c/600608/ and https://review.openstack.org/600613 - they were osic specs previously approved in pike so you'd probably have the best context on those
16:15:49 mriedem per-instance live migration timeout
16:16:05 mriedem cfriesen: you too for starlingx has some similar functionality ^
17:10:13 cfriesen mriedem_bbq: will take a look
17:11:39 cfriesen mriedem_bbq: oh man, I thought that got sorted out a couple releases back. guess not.
17:22:29 dansmith mriedem_bbq: did you want me to put my money in place of my mouth on this? https://review.openstack.org/#/c/600085/
17:54:10 mriedem dansmith: i can update it, unless you're looking to poke on it
17:54:16 mriedem was doing spec reviews before the ptg
17:54:20 mriedem trying to anyway
17:59:12 dansmith I'm happy for you to do it, I just wasn't sure if you were expecting me to

18:27:28 dansmith let it be known henceforth that leakypipes loves pets and will be up for helping with future BFV hardening
18:27:30 mriedem that guy, he does love pets
18:27:32 mriedem and bfv i've heard
