| 14:55:57 | winiciusallan[m] | folks, I saw a lot of discussion on the mail list about a spot instance service in Nova, some people have even start implementing, but this wasn't go further | |
| 14:56:04 | winiciusallan[m] | CERN has a external service for this https://gitlab.cern.ch/cloud-infrastructure/aardvark | |
| 14:56:29 | winiciusallan[m] | do you know by chance if having this kind of service integrated into Nova is interest for the community? | |
| 15:00:08 | winiciusallan[m] | i'm thinking of implementing this as part of my final thesis. this will make other research regarding billing and charge strategies easier to evaluate | |
| 15:14:06 | opendevreview | Merged openstack/nova master: tox: Remove override of install_command https://review.opendev.org/c/openstack/nova/+/984918 | |
| 15:14:48 | opendevreview | Merged openstack/nova master: docs: Update development-environment guide https://review.opendev.org/c/openstack/nova/+/984956 | |
| 15:42:51 | sean-k-mooney | winiciusallan[m]: we decieed that it should not be in nova | |
| 15:43:24 | sean-k-mooney | we reivwed the sepec and went back and forth but decieed it shoudl live as its own thing external to nova | |
| 15:43:44 | sean-k-mooney | winiciusallan[m]: i have tought that this could live in watcher in the future | |
| 15:43:52 | sean-k-mooney | there is also a host based version in blazar today | |
| 15:44:23 | sean-k-mooney | but i think watcher can facilatate a more granular approch similar to the orgianl concept | |
| 15:49:38 | winiciusallan[m] | sean-k-mooney: yeah, thinking about watcher it looks more natural considering the architecture of the service | |
| 15:50:32 | winiciusallan[m] | I dropped a message on scientific-sig asking if people have use cases or gaps that they would like to improve | |
| 15:51:14 | winiciusallan[m] | one from NASA talked about GPUs being expensive and it might be a use case for them | |
| 15:51:22 | sean-k-mooney | i dont know if i ever wrote up a spec for it there. but the idea was to annotate the isntance via the flavor or instance metadta wiht lifecycle:premtable=ture | |
| 15:51:45 | winiciusallan[m] | others from CERN and nectar-rc use aardvak | |
| 15:52:05 | sean-k-mooney | then have a new goal for permation and 1-n stragies for how to dop it | |
| 15:52:38 | winiciusallan[m] | sean-k-mooney: +1 with this approach. this is how the first spec was written on nova | |
| 15:53:26 | sean-k-mooney | so the firction with doing this is nova is https://docs.openstack.org/nova/latest/contributor/project-scope.html#no-more-orchestration and https://docs.openstack.org/nova/latest/contributor/project-scope.html#no-more-orchestration | |
| 15:53:26 | winiciusallan[m] | probably different strategies for how to find the best instance to preempt and also being possible to extend a custom strategy | |
| 15:53:31 | winiciusallan[m] | sounds good | |
| 15:54:01 | sean-k-mooney | we have basicly said we do not want to build complex orchstration logic in nova or optimise for batch processing | |
| 15:54:16 | sean-k-mooney | but we want to make sure that higher level service can express the policy on top | |
| 15:54:35 | sean-k-mooney | which is where aardvark or watcher can play a role | |
| 15:55:33 | sean-k-mooney | winiciusallan[m]: ya so there are a lot of intersting way to decie which instnace to preempt and what that means (either delete or shelve) | |
| 15:55:42 | sean-k-mooney | for example delete oldest first | |
| 15:55:50 | sean-k-mooney | delete bigest first | |
| 15:56:02 | winiciusallan[m] | best fit and so on... | |
| 15:56:17 | sean-k-mooney | delete instnace on expensive hosts or where there is pressure based on mettrics | |
| 15:56:31 | sean-k-mooney | so watcher with its plugable goals and stragies | |
| 15:56:38 | sean-k-mooney | woudl allow you to experiment with those | |
| 15:58:34 | sean-k-mooney | winiciusallan[m]: https://redhat.atlassian.net/browse/RHOSRFE-142 is a downstream tracker i filed to do this "eventualy" | |
| 15:58:57 | sean-k-mooney | but its not someting i have had time to activly work on and i dont expect to actully do that any time soon | |
| 15:59:27 | winiciusallan[m] | i'll be happy to help you with this if it is possible | |
| 16:00:02 | sean-k-mooney | https://etherpad.opendev.org/p/r.bf5f1185e201e31ed8c3adeb45e3cf6d#L747 | |
| 16:00:09 | winiciusallan[m] | I need to sync from my side what is the scope for my thesis, there is a slighly chance of testing different strategies... | |
| 16:00:36 | sean-k-mooney | well if you want to talk about this more in the context of watcher feel free to reach out in #openstack-watcher | |
| 16:00:54 | sean-k-mooney | we are also haveing the PTG next week so we could chat about it more there too if you were interested | |
| 16:02:11 | sean-k-mooney | winiciusallan[m]: no worries either way, that the most recent context i can provide on this topic so if you do or do not have scope to wrok on this either is fine | |
| 16:03:21 | winiciusallan[m] | at a first moment, i was thinking of discussing this on nova ptg, but since answered me in advance we can discuss this on watcher's ptg | |
| 16:03:31 | winiciusallan[m] | let's take the discussion to #openstack-watcher | |
| 16:03:34 | winiciusallan[m] | joining there | |
| 16:27:38 | opendevreview | Stephen Finucane proposed openstack/nova master: Fix functional tests and mypy on macOS https://review.opendev.org/c/openstack/nova/+/937727 | |
| 17:04:05 | gmaan | bauzas gibi console proxy in threading mode change lgtm now https://review.opendev.org/c/openstack/nova/+/976089 | |
| 17:26:37 | gibi | gmaan: ack thanks. Maybe next week before the PTG calls I will have time to get to it | |
| 18:15:01 | gibi | Uggla: sean-k-mooney: I filled out the details of the PCI Grouping topic in the etherpad | |
| 18:16:12 | sean-k-mooney | gibi: ++ | |
| 18:16:13 | gibi | and that is my exit today | |
| 18:16:15 | sean-k-mooney | thanks | |
| 18:17:54 | gibi | btw, does AI crawlers know how to read an etherpad? | |
| 18:18:16 | sean-k-mooney | i expoerted it to a file when i wanted it to fix spelling | |
| 18:18:21 | gibi | and does our Agentic overlord LLMs can read an etherpad? | |
| 18:18:21 | sean-k-mooney | but proably yes | |
| 18:19:12 | sean-k-mooney | it can read it in that its just a webpage | |
| 18:19:21 | sean-k-mooney | but i didnt want to givbe it a link | |
| 18:19:35 | sean-k-mooney | because i didnt want it to do random things | |
| 19:25:07 | Uggla | gibi, thanks, but regarding the hour 20:15 looks a bit late and not cool. I wish you a good WE and please rest during the WE. Next week will be intense. | |
| 20:43:58 | gibi | Uggla: thanks. It is complicated. :D | |

| 06:40:07 | tafkamax | Hi, I have a question regarding nova-pythonclient. Will commands like nova reset-state <SERVER_ID> be migrated? | |
| 06:40:23 | tafkamax | So when python-openstackclient will become the only one standing. | |
| 06:42:37 | jkulik | Isn't it already available through `opennstack server set --state active`? | |
| 06:47:01 | tafkamax | oh okay, will try | |

| 14:04:08 | dansmith | Uggla: didn't you just say we were supposed to be in the cinder room? | |
| 14:04:19 | dansmith | there was some confusion about where to be (here in the cinder room) | |
| 14:05:03 | Uggla | no liberty Nova room (sorry if it was not clear) | |
| 15:15:04 | melwitt | gibi: thanks for checking on the nova-vtpm patch. I saw it failed again :( so I will investigate | |
| 15:36:01 | gibi | Uggla: your nova bug stats will not like my effort of filing bugs for eventlet tech debt https://bugs.launchpad.net/nova/+bugs?field.tag=eventlet-removal | |
| 15:37:10 | gibi | melwitt: ack, thanks for trying to stabilize it | |

| 16:10:30 | tkajinam | I'm just wondering how memfd works for allocation. Should we still calculate memory allocation according to the numa topology ? | |
| 16:10:48 | tkajinam | (assuming we still have to align cpu amd mem in numa-aware way, looking at it may be used for ovs-dpdk | |
| 16:11:26 | tkajinam | by the way memfd is heavily used in cc case (actually instances with snp support or tdx support uses it implicitly and it's interesting after learning the mechanism quite recently | |
| 16:22:28 | Uggla | @gibi, I think the bug you opened are valid so can be triaged. Anyway that's not too bad. | |
| 16:23:21 | Uggla | tkajinam, good to know memfd is something interesting for CC case. | |
| 16:23:40 | Uggla | tkajinam, if you have a doc pointer on it I'm interesting. | |
| 16:24:10 | Uggla | tkajinam, probably a good point to convince my mgmt that this feature is interesting. | |
| 16:46:03 | tkajinam | Uggla, let me find one, but it might not match your use case largely because 1) memfd is implicitly used by qemu 2) the main objective of using memfd is not performance but allocating private/encrypted memory for vm | |
| 16:50:00 | Uggla | tkajinam maybe part of an answer to your question --> https://lwn.net/Articles/990663/ | |
| 16:51:05 | tkajinam | ok so you still need to maintain memory:numa mapping (seeing that host-nodes=0) | |
| 16:52:18 | tkajinam | Uggla, this might be too-much information but captures the qemu's internal logic to leverage memfd for private memory area https://review.opendev.org/c/openstack/nova-specs/+/983376/comment/658b8a62_20071ca8/ | |
| 16:54:29 | sean-k-mooney | tkajinam: memfd can have the shared flag set or not i bleive | |
| 16:54:41 | tkajinam | yeah | |
| 16:54:46 | sean-k-mooney | i woudl prefer to always have memfd shared=true | |
| 16:55:13 | sean-k-mooney | but keep "annoumus" spelled correctly for those that want to opt out | |
| 16:55:27 | sean-k-mooney | i.e. evnetually memfd i think shoudl become the default | |
| 16:55:38 | sean-k-mooney | but ya in newer qemu memfd does not need numa | |
