#openstack-nova - 2017-10-24
11:48:12 bauzas also, I did made a compromise, I had to add that option before we're going to use it
11:48:20 efried saw that.
11:48:25 openstackgerrit Merged openstack/nova master: Add alternate hosts https://review.openstack.org/486215
11:48:27 efried Not sure why
11:48:35 openstackgerrit Merged openstack/nova stable/pike: Add functional migrate force_complete test https://review.openstack.org/509924
11:48:41 efried but don't see any reason to object
11:48:44 bauzas I thought oslo.config was somehow having an "experimental" or "next" attribute for the opt, but no
11:48:48 openstackgerrit Merged openstack/nova stable/pike: Add functional for live migrate delete https://review.openstack.org/509925
11:48:55 bauzas efried: because libvirt and xen will both use it
11:49:07 bauzas of course we could just have it in one set
11:49:14 bauzas and wait the set to be merged
11:49:24 bauzas but that could take much longer
11:49:37 efried bauzas Naw, you can just base both of those changes on this one.
11:49:51 bauzas efried: that's correct, hence my commit msgh
11:49:57 bauzas anyway
11:50:00 bauzas let's wait for reviews
11:50:15 bauzas I'm just writing the yippikay libvirt side
11:50:18 efried There's nothing stopping you from having branches in a series.
11:50:31 efried My ksa-adapter series has several
11:50:36 efried :)
11:54:37 efried bauzas Okay, left review. Thanks for the talk.
12:02:02 efried johnthetubaguy yt?

12:49:51 openstackgerrit Merged openstack/nova stable/pike: Remove dest node allocations during live migration rollback https://review.openstack.org/509926
12:57:46 cdent efried: did you resolve your resources= thing satisfactorily?
12:58:04 efried cdent Sorry, which resources= thing was that?
12:58:18 cdent [t 2wmI]
12:58:19 purplerbot <efried> Anyone know if we're supposed to handle queryparams with multiple values in the placement API? [2017-10-23 20:04:11.392701] [n 2wmI]
12:58:20 efried cdent Oh, whether you could specify a key multiple times in a querystring?
12:58:36 efried Yeah, the answer was "no", but edleafe thought you would remember why it was decided that way.
12:58:41 cdent the defacto standards with query params is that multiple of the same param should work, but it is not something we really do in nova
12:59:06 mriedem only for sort key/dir i think
12:59:47 efried cdent Well, at least for GET /allocation_candidates and GET /resource_providers?resources= it doesn't work.
12:59:50 efried You'll only get the last one.
13:00:28 cdent yes, that’s a) intentional b) because of the way it is coded c) a fairly arbitrary choice
13:01:05 efried Okay, wfm
13:01:07 cdent the confusion being avoided is whether a list is created by commas or multiple params, and since most people didn’t feel comfy with multiple params, commas was chosen, exclusively

13:12:39 belmoreira dansmith: mriedem: I'm looking on how to have placement with cellsV1. Need some guidance.
13:15:13 belmoreira My understanding is that I will need to have a separated placement service + nova_api DB + keystone for each child cell. Is this correct?
13:22:40 mriedem belmoreira: i've always thought of placement as global to nova, but it's only used by the "cell" filter scheduler i guess, so it might make sense to only be per-child cell with cells v1
13:22:50 mriedem the global api parent cell scheduler won't rely on placement
13:23:13 mriedem belmoreira: i don't know about keystone being per child cell
13:23:23 mriedem is that what you already do today?
13:23:51 mriedem nova_api db should be global
13:24:01 mriedem since build requests are created in the api cell
13:24:22 mriedem belmoreira: which release are you targeting here?
13:24:40 belmoreira mriedem: let me clarify
13:25:36 belmoreira I'm running nova newton release. We have one nova_api DB (requirement in newton) that is global
13:26:16 belmoreira when upgraded I didn't enable placement but it's a requirement before moving to Ocata/Pike
13:27:07 mriedem belmoreira: yeah so in ocata, the only things that talk to placement are nova-scheduler in the cell and nova-compute
13:27:52 bauzas we always thought placement as being global, like we also said for the scheduler
13:27:53 mriedem so placement could be deployed per-cell, but if you can, it's probably smart to deploy it globally to make the transition easier to cells v2
13:28:00 belmoreira because nova-scheduler is per cell in cellsV1 do I need a placement per cell?
13:28:23 mriedem bauzas: with cells v1 there are 2 levels of scheduling
13:28:27 bauzas mriedem: if placement would be per cell, that would mean 2 layer of scheduling, which I disagree
13:28:33 bauzas mriedem: yup I know and I don't like it :)
13:28:34 mriedem there already is
13:28:48 mriedem like i said, if you deploy placement globally, i think it'll be easier in the long-run
13:28:53 mriedem to transition to cells v2
13:28:56 belmoreira I was always thinking in the placement as global... but I'm not seeing how to make it work with cellsV1
13:29:00 bauzas mriedem: but the consensus we had long in the past with alaski and dansmith was that 2 scheduling layers was a terrible idea
13:29:01 mriedem b/c with cells v2 there is only 1 scheduler
13:29:25 dansmith belmoreira: why can't you point all the child cells at the global api?
13:29:26 mriedem belmoreira: just think of it like any other global service
13:29:30 dansmith er, global placement api
13:29:34 bauzas so, AFAIR, we discussed about just having a CellFilter
13:29:48 bauzas which would filter per cell or somehow like that
13:30:01 dansmith bauzas: what does that have to do with what belmoreira is asking?
13:30:24 bauzas maybe I misunderstood
13:30:37 belmoreira if I point them to the global placement doesn't it means that I do the transition to cellV2 in Ocata?
13:30:43 dansmith belmoreira: no
13:30:55 belmoreira because then I need to do all the node/cells mappings
13:30:59 dansmith oh
13:31:00 dansmith hmm
13:31:03 bauzas wait
13:31:07 mriedem no
