#openstack-nova - 2017-10-23
15:04:20 efried Why is it a problem if the remaining capacity is included for classes that weren't claimed?
15:04:23 openstackgerrit Merged openstack/nova master: Move shred to privsep. https://review.openstack.org/495537
15:04:31 cdent jaypipes: i wasn’t meaning to be exclusive, rather that the entire provider should be reprsented (plus whatever else)
15:04:35 openstackgerrit Merged openstack/nova master: Move xend existence probes to privsep. https://review.openstack.org/495538
15:05:21 jaypipes dtantsur: done
15:05:47 jaypipes efried: I don't think it is. I think it was probabl jjst an oversight
15:05:54 jaypipes god damnb this mac keyboard... :(
15:06:06 efried jaypipes Which part is an oversight?
15:06:16 efried jaypipes Including the extra RCs or excluding them?
15:06:29 jaypipes efried: that the provider summary for a provider only includes resources that were requested and not all resources the provider had
15:06:36 efried jaypipes Which way are we saying it's *supposed* to be?
15:07:00 efried That it should include *all* of them, I guess. I agree with that.
15:07:59 cdent efried: yes, all
15:08:04 efried ++
15:08:25 edleafe efried: cdent: of what use do you see non-requested resources in the provider_summary?
15:08:30 alex_xu jinx means a person bring bad luck?
15:09:00 jaypipes efried: yeah, sohuld include all the inventories, not just the ones for requested resources
15:09:06 cdent alex_xu: that’s one meaning, but the meaning we are using is “you said something at the same time as me”
15:09:08 efried alex_xu Heh, not in this context. It's a silly game kids play: when two people say the same thing at the same time, the first one to say "jinx" "wins"
15:09:35 efried alex_xu There's various penalties for "losing". The one I grew up with was that the "loser" has to remain silent until you say their name.
15:09:36 cdent in the real version of the game the loser can’t speak for some amount of time
15:09:40 cdent jinx!
15:09:54 cdent let’s efried off the hook
15:10:07 efried alex_xu Another one I've heard of is that the "winner" gets to punch the "loser" until the loser recites some incantation.
15:10:29 efried "Jinx poke, you owe me a coke, times onetwothreefourfive...."
15:10:46 cdent edleafe: the provider summary, as I understand it, is supposed to list the resource providers in a complete. From what’s there we should be able to conceptualize what the resource provider providers, not just what we are using from it
15:10:57 cdent whether that is of use or not is unclear
15:11:19 dansmith alex_xu: in case you're wondering, seeing it spelled out in writing like we just have makes it sound even dumber than it normally does
15:11:21 cdent s/, not/are, not/
15:11:32 dansmith alex_xu: so if you're thinking "wtf is wrong with these guys" ... you're not alone
15:11:42 cdent no need to be a dick about dansmith
15:12:02 dansmith cdent: s/about/about it/ right?
15:12:04 alex_xu haha :)
15:12:19 cdent dansmith: if you like but the typo is in your favor, so maybe we keep it?
15:12:25 dansmith heh
15:13:01 dansmith cdent: I'm only saying that I've never seen the rules of jinx written out before and I'm feeling kindof embarrassed for my entire generation now that I have :)
15:13:14 efried Agreed
15:13:44 cdent It predates our generation yeah? I thought of it as kind of antique even when I was a child and I’m nearly the oldest here.
15:13:57 efried My dad is the one who told me about the punching thing.
15:14:08 edleafe yeah, it was old when *I* first heard about it
15:14:18 edleafe written on stone tablets it seems even lamer
15:16:08 dansmith I have no idea, I assumed it was too dumb for generations prior, but I'm sure you're right
15:17:00 efried The internet (which is never wrong) hints that it may go back as far as 16th century Scottish tavern games.
15:17:16 cdent Isn’t each subsequent generation immensely cooler than the last? My (adult) children assure me this is the case.
15:18:18 edleafe cdent: Your children are correct, but just in your family
15:18:18 dansmith heh
15:18:28 cdent thank you old man
15:19:17 cdent Scotland has a lot to answer for.
15:20:29 mriedem dansmith: are you ok with this before i propose a backport https://review.openstack.org/#/c/513001/
15:20:54 dansmith omg no
15:20:55 dansmith wtf
15:21:10 dansmith ugh
15:21:21 efried So... not okay with it
15:21:36 efried Just reading between the lines here.
15:21:38 mriedem i brought this up when it was initially being reviewed, pretty sure anyway - but there is no api schema restriction in the baremetal api about the resource class name
15:22:07 dansmith I very specifically think this is completely broken
15:22:11 dansmith I know and I fought hard to NOT do this ambiguous thing
15:22:51 openstackgerrit Matt Riedemann proposed openstack/nova master: Only add CUSTOM_ prefix if required https://review.openstack.org/513001
15:22:56 mriedem pulled it out of the gate
15:22:59 mriedem johnthetubaguy: ^
15:24:17 johnthetubaguy so VCPU becomes CUSTOM_VCPU, just CUSTOM_FOO stays CUSTOM_FOO
15:24:33 johnthetubaguy its a pain to setup the system with CUSTOM_ in only half the places
15:24:58 mriedem VCPU is a standared resource class
15:25:41 johnthetubaguy yep, that's where it gets funky, that code keeps it as always CUSTOM_ at the start, it just avoids the double encoding
15:25:43 mriedem if you set the ironic node.resource_class as vcpu, then we'd translate that to CUSTOM_VCPU yeah
15:25:56 dansmith mriedem: thanks
15:25:57 johnthetubaguy that's what I mean, I should have added a test for that really
15:26:23 dansmith I just commented on that patch,
15:26:24 mriedem the ironic docs are at least pretty clear about this https://docs.openstack.org/ironic/pike/install/configure-nova-flavors.html#scheduling-based-on-resource-classes
15:26:31 dansmith but I'm super against us adding this ambiguity
15:27:28 dansmith anything else that wants to look at placement-related data for ironic nodes would have to implement the same "is it already right, or not" behavior when taking the ironic class and turning it into a placement class
15:27:44 dansmith instead of just "apply the following set of rules to get from ironic to placement"
15:27:46 openstackgerrit Stephen Finucane proposed openstack/nova master: console: introduce the VeNCrypt RFB authentication scheme https://review.openstack.org/345398
15:27:46 openstackgerrit Stephen Finucane proposed openstack/nova master: console: introduce framework for RFB authentication https://review.openstack.org/345397
15:27:47 openstackgerrit Stephen Finucane proposed openstack/nova master: doc: Document TLS security setup for noVNC proxy https://review.openstack.org/500544
15:27:47 openstackgerrit Stephen Finucane proposed openstack/nova master: console: provide an RFB security proxy implementation https://review.openstack.org/345399
15:27:49 dansmith as documented in the ironic docs there
15:28:19 johnthetubaguy I get that, just as an operator, I need to remember if its Nova or Ironic I am talking to when setting different names for things
15:28:54 dansmith but they're two totally different things
15:29:01 dansmith ironic's resource class predates our use of it,
15:29:13 dansmith and can be set to completely incompatible things
15:29:37 mriedem yeah, note the baremetal.with-GPU example in the ironic docs,
15:29:46 mriedem nova replaces special characters like the '.' with underscores
15:30:05 mriedem so the CUSTOM_ prefix isn't the only thing that will be different
15:30:48 johnthetubaguy dansmith: the spec says it was added for placement: https://specs.openstack.org/openstack/ironic-specs/specs/not-implemented/node-resource-class.html
15:31:13 johnthetubaguy my thinking was more simplistic really... can't I just set all the strings to the same thing?
15:31:16 dansmith johnthetubaguy: but like two releases before we actually had that stuff, and with zero restriction :)
15:31:28 openstackgerrit Stephen Finucane proposed openstack/nova master: Move loopback setup and removal to privsep. https://review.openstack.org/495664
15:31:28 openstackgerrit Stephen Finucane proposed openstack/nova master: Move the idmapshift binary into privsep. https://review.openstack.org/495541
15:31:29 openstackgerrit Stephen Finucane proposed openstack/nova master: Move kpartx calls to privsep. https://review.openstack.org/500354
15:31:29 openstackgerrit Stephen Finucane proposed openstack/nova master: Move nbd commands to privsep. https://review.openstack.org/500351
15:31:30 openstackgerrit Stephen Finucane proposed openstack/nova master: Move blkid calls to privsep. https://review.openstack.org/500398
15:31:31 johnthetubaguy dansmith: yep, agreed.
15:31:36 dansmith johnthetubaguy: yeah I know, but it's not equivalent
15:32:01 dansmith johnthetubaguy: it'd be like us using the uuid, as CUSTOM_$UUID and then people wanting to set their uuid to CUSTOM_$UUID... they're not the same field
15:33:55 johnthetubaguy it just seems to me like 80% of folks are setting the resource classes to something they can request in a flavor, they care little about the translation, even if they probably should
15:34:36 johnthetubaguy but I guess its dangerous to assume they are the same thing, when you use them, because they may not be
15:34:41 dansmith and integers are like floats, but usually without the decimal point?
15:36:21 johnthetubaguy I was thinking about following up with a new microversion that forces all new resource classes to follow the placement patterns, etc.
15:36:54 johnthetubaguy but that is kinda aweful in its own way
