10:11:55 aspiers sean-k-mooney, efried, bbobrov: exciting progress! http://paste.openstack.org/show/754889/
10:13:21 aspiers cdent: inventory stuff seems to be working nicely :) ^^^
10:14:01 cdent excellent, glad to hear it
10:42:27 sean-k-mooney aspiers: yep that does look like its working well
10:42:59 sean-k-mooney aspiers: you said you finally booted an sev instance with openstack yesterday right or is that the goal for today
10:43:35 sean-k-mooney aspiers: cdent actully should th max unit on that inventory not be 1
10:44:02 sean-k-mooney you can only have one mem_encryption_context per vm right
10:45:19 openstackgerrit sean mooney proposed openstack/os-vif master: only disable mac ageing for ovs hybrid plug https://review.opendev.org/672834
10:45:33 sean-k-mooney this a relitivly minor nit
10:55:12 aspiers sean-k-mooney: booting is the goal for today
10:56:34 aspiers sean-k-mooney: I don't get why you think max_unit should be 1? there are 16 slots configured on that machine
10:56:57 sean-k-mooney yes but max_unit is the maxium amount you can request in a singe request
10:56:57 aspiers ohhh, are you saying max_unit represents the maximum per VM, not the maximum per host?
10:57:03 sean-k-mooney yes
10:57:04 aspiers ok I didn't know that
10:57:10 aspiers in that case yeah it should be 1
10:57:12 aspiers good catch
10:57:14 sean-k-mooney total is the total capasity
10:57:21 aspiers right that never quite made sense before
10:57:23 aspiers easy to fix
10:57:39 sean-k-mooney ya as i said minor nit
10:57:46 aspiers minor but v important!
10:57:50 sean-k-mooney we will only ever ask for 1 anyway
10:57:56 aspiers true
10:57:59 aspiers well
10:58:14 aspiers yeah
10:58:32 aspiers unless some operator requested the resource directly via the flavor
10:58:37 sean-k-mooney still it does not hurt to be defensive
10:58:40 sean-k-mooney ya
10:59:48 aspiers sean-k-mooney: is min_unit=1 correct though?
11:00:11 sean-k-mooney can you ask for less then 1 allocation of something if you want a resouce
11:00:14 sean-k-mooney yes it is
11:00:45 sean-k-mooney the min unit only applie if you ask for a resouce of that type
11:01:22 sean-k-mooney and since we dont want people saying resouce:MEM_ENCRYPTION_CONTEXT=0 it is correct
11:01:28 aspiers got it
11:01:30 aspiers thanks
11:02:35 sean-k-mooney resouce:MEM_ENCRYPTION_CONTEXT=0 would actully for the vm to land on a host that supported sev but not consume sev resouces so it could be used incorrectly by opertors to stave those nodes or ram cpus and disk
11:03:02 sean-k-mooney /for/force
11:03:51 aspiers good point
11:28:25 openstackgerrit Luyao Zhong proposed openstack/nova master: libvirt: Enable driver configures PMEM namespace https://review.opendev.org/634549
11:28:25 openstackgerrit Luyao Zhong proposed openstack/nova master: Report pmem namespaces resources by provider tree https://review.opendev.org/634551
11:28:26 openstackgerrit Luyao Zhong proposed openstack/nova master: Indroduce new LibvirtConfigGuestPMEM https://review.opendev.org/672956
11:28:26 openstackgerrit Luyao Zhong proposed openstack/nova master: Populates existing pmems in libvirt device manager https://review.opendev.org/672957
11:28:27 openstackgerrit Luyao Zhong proposed openstack/nova master: Support instance creation and resize with pmems https://review.opendev.org/672958
11:31:38 openstackgerrit Surya Seetharaman proposed openstack/nova master: API microversion 2.75: Add 'power-update' external event https://review.opendev.org/645611
11:39:58 efried mnaser: re openstacksdk:
11:39:58 efried spec: http://specs.openstack.org/openstack/nova-specs/specs/train/approved/openstacksdk-in-nova.html
11:39:58 efried code: https://review.opendev.org/#/q/status:open+project:openstack/nova+branch:master+topic:bp/openstacksdk-in-nova
11:40:58 efried mnaser: note that we're not using clouds.yaml. We're using newly introduced functionality to consume ksa.loading oslo.config opts to build the Connection obj.
11:42:27 efried aspiers, sean-k-mooney: You can't ask placement for an allocation of 0.
11:43:13 sean-k-mooney efried: because we explcitly check or because we set min_unit to 1
11:43:15 efried If you want to land on a SEV host but not consume SEV resources (why??) you would have to require the SEV trait. Which of course wouldn't be generic for SEV/MKTME like the rc is.
11:43:30 sean-k-mooney efried: we dont
11:43:43 efried sean-k-mooney: I'm actually not sure. Because I'm pretty sure you can't set min_unit to 0 either.
11:43:59 sean-k-mooney efried: aspiers was just asking if min_unit=1 was correct
11:44:04 sean-k-mooney and i was saying yes it is
11:44:08 efried yeah, it certainly is.
11:44:17 efried and per the design, max_unit=1 is also correct.
11:44:21 efried as you said
11:48:06 efried alex_xu: yt?
11:50:04 efried sean-k-mooney, aspiers: Who among cores do y'all think would be appropriate reviewers for https://review.opendev.org/670189 (harden get_domain_capabilities)?
11:52:32 sean-k-mooney good question. am most of the redhat folk are familar with libvirt, matt knows all but is also always over subsribed, maybe alex_xu on the intel side
11:53:16 sean-k-mooney to be honest we added a tone of comments so most core should be able to review at this point
11:54:36 sean-k-mooney short list would proably be dansmith bauzas alex_xu or mriedem
12:00:19 sean-k-mooney stephenfin is on pto today and maybe monday hence why he is not on the list
12:04:19 sean-k-mooney johnthetubaguy: by the way regarding https://review.opendev.org/#/c/669190/
12:05:29 sean-k-mooney one i assume you still want to merge ^ but second i assume you are not against either reverting the feature entrily or making it work properly
12:24:39 openstackgerrit Merged openstack/os-vif master: Blacklist sphinx 2.1.0 (autodoc bug) https://review.opendev.org/672856
12:57:37 aspiers efried: re. core reviewers, I can't add anything to sean-k-mooney's answer
12:57:52 aspiers I just found an issue with some of the SEV tests
12:58:11 aspiers turns out you can't use decorators on classes after all :-( or at least in some circumstances. digging more now
13:06:25 mriedem if anyone has a stein env handy could you see if you can recreate this? https://bugs.launchpad.net/nova/+bug/1837995
13:06:25 openstack Launchpad bug 1837995 in OpenStack Compute (nova) ""Unexpected API Error" when use "openstack usage show" command" [Undecided,New]
13:06:33 mriedem i don't see why it would happen but if it is it should be fairly obvious
13:53:38 sean-k-mooney mriedem: i can unstack and restack an env but i dont have one to hand
14:09:45 aspiers stupid question #734: what's a "remote security group" as returned by "openstack security group rule list" ?
14:10:29 openstackgerrit Eric Fried proposed openstack/nova master: DNM: Where have all the global_request_id gone? https://review.opendev.org/672986
14:10:43 aspiers and what's the effect of rules where the IP protocol / range are both None?
14:11:02 aspiers I would assume it just allows everything, but I'm not seeing that behaviour
14:13:11 efried aspiers: This sounds like a question for #openstack-keystone
14:13:32 aspiers oh really? I thought secgroups were part of nova
14:13:45 aspiers I guess my knowledge in this area is 5 years out of date or something
14:15:32 mriedem you're both wrong
14:15:34 mriedem neutron
14:15:39 aspiers haha
14:15:45 aspiers that would have been my second guess
14:16:01 aspiers actually I don't know why it wasn't my first
