#openstack-nova - 2018-12-03
20:09:09 mriedem there is a special hack in castellan for nova and cinder
20:09:16 mriedem which have their own no-op in-tree key managers for testing
20:09:37 mriedem ConfKeyManager is not documented since it's not something we want people using in prod
20:10:15 mriedem the backend itself is open-ended https://github.com/openstack/castellan/blob/master/castellan/key_manager/__init__.py#L25
20:10:30 sean-k-mooney oh ok... it would be nice to atleast document that in hte nova code but maybe i missed it
20:15:04 openstackgerrit Matt Riedemann proposed openstack/nova master: Create BDMs/tags in cell with instance when over-quota https://review.openstack.org/621692
20:18:40 mnaser can i ask what's the state of https://review.openstack.org/#/c/554218 or https://review.openstack.org/#/c/554212 ? -- i have a use-case that might need pre-emptible instances so im curious about those
20:18:46 mriedem this ^ is a pretty straight-forward regression fix since pike
20:23:18 sean-k-mooney mnaser: anyway i had taught we said we woudl try and complete those in denver but honestly i dont know
20:23:57 tssurya mnaser, sean-k-mooney: yea we had discussed it in denver ptg, at this point I think it needs more core reviews
20:24:18 sean-k-mooney tssurya: and a couple of pep8 fixes :)
20:24:30 mnaser sean-k-mooney, tssurya: i can help in contributing the code needed and cleaning it up
20:24:48 tssurya sean-k-mooney: heh right
20:24:49 mnaser both add a lot of flexibility in terms of being able to do more
20:25:22 sean-k-mooney mnaser: yes when i was at intel i was also looking at other ways of using the pending state.
20:25:51 sean-k-mooney mnaser: e.g. useing it as a maker to signal that i need to autoscale the cloud rather the reap instances
20:26:07 sean-k-mooney mnaser: yep that was basicaly my idea too
20:26:09 mnaser pretty much :)
20:26:11 mnaser also saving power
20:26:16 tssurya mnaser: thanks for the interest, I think that would be great! my colleague had a couple of code patches also up for review https://review.openstack.org/#/q/status:open+project:openstack/nova+branch:master+topic:bp/enable-rebuild-for-instances-in-cell0 and https://review.openstack.org/#/q/status:open+project:openstack/nova+branch:master+topic:bp/introduce-pending-vm-state
20:26:59 tssurya but basically he is waiting for the specs to get merged, please feel free to chip in your ideas/ help is surely appreciated
20:27:02 sean-k-mooney the idea was if you have a mixed iroic/rsd and libvirt could you could provision new libvirt nodes in a seperate admin tenant using the resocses from teh ironic/rsd nodes
20:27:33 mnaser sean-k-mooney: and that means you can have baremetal and/or ironic in the same cloud and be able to share those resources across
20:27:51 mnaser tssurya: ill try to see whats going on with the pep8 at least
20:27:59 mnaser sounds silly but set it up for success :p
20:28:28 mriedem personally i haven't looked at the latter spec, and haven't been back to the former since i ripped it up in june
20:29:05 mriedem and then no one was really talking about it anymore
20:29:13 mriedem and we already have a bunch of other stuff going on
20:29:28 mriedem so i wasn't going out of my way to look for more shit we can cram into this release while we still have other fires burning
20:29:31 mriedem but that's just me
20:29:38 sean-k-mooney mnaser: yep. we did not have time to explore it fully because of resoucign but we belived the pending state was generally useful beyond the proposed usecase
20:29:48 openstackgerrit Mohammed Naser proposed openstack/nova-specs master: Enable rebuild for instances in cell0 https://review.openstack.org/554218
20:29:54 mnaser i fixed the pep8 for all that matters
20:30:24 tssurya mnaser: thanks!
20:30:54 mnaser mriedem: do you see a more ideal/cleaner path for pre-emptible instances within nova?
20:31:09 sean-k-mooney mnaser: mriedem i think johnthetubaguy had this working out of tree last cycle i belive so it would be interesting to know what is out standing but ya i also know we have a lot of todos
20:32:26 sean-k-mooney from a parity point of view vs aws it would be nice to have. anyway my pizza is just cooked so im going to say goodnight
20:32:29 sean-k-mooney o/
20:34:05 mriedem mnaser: honestly i'm not at all up to date on what's being proposed anymore
20:34:05 tssurya sean-k-mooney: there was a presentation at the summit on the same: https://www.openstack.org/summit/berlin-2018/summit-schedule/events/22438/science-demonstrations-preemptible-instances-at-cern-and-bare-metal-containers-for-hpc-at-ska
20:34:20 mriedem something something build failure -> notification loop -> rebuild from cell0
20:34:44 mnaser mriedem: yeah that idea seems to be around having an option where nova leaves thing in PENDING instead of ERROR when NoValidHost
20:35:03 mnaser and then $some_service would do things and either request rebuild or reset state to error
20:42:50 dansmith mnaser: yep that's what we discussed in dublin
20:43:04 dansmith I too haven't circled back to it because progress seems to be very infrequent and it's hard to maintain context on it
20:43:46 mnaser yeah i can imagine losing context over time with a lot of stuff going on can be hard :x
20:43:55 mnaser i just mostly sync'd up through a bunch of reading and talks
22:17:43 mriedem dansmith: thanks, lots of good comments in there https://review.openstack.org/#/c/616037/
22:25:53 dansmith mriedem: cool, I'll try to get to the rest of it soonish

01:33:22 Zer0Byte_ hey
01:33:29 Zer0Byte_ i have a quesstion maybe someone can help me
01:34:09 Zer0Byte_ im trying to setup hw:cpu_cores in openstack queens but just create each cpu as sockets and complety ignore this value
01:34:16 Zer0Byte_ any idea if i have to set something else
