| 16:43:04 | cardoe | I think right now just figuring out how ironic folks can best work with the nova folks. I don't wanna make it harder for you folks to review or accept patches. So if we should be working on testing improvements we can do that. | |
| 16:43:33 | cardoe | From the operators I've asked the "Failure prepping block device" is one that's pretty annoying for them to handle. | |
| 16:46:12 | Uggla | ok, I think it helps to focus. | |
| 16:46:30 | Uggla | Am i wrong or there is not patch regarding "Failure prepping block device" yet ? | |
| 16:46:58 | cardoe | There's just a backport adding another exception into the list of allowed to be seen by the user. | |
| 16:47:35 | cardoe | So what I'm wondering is if it would be better to make a list of those that should be seen by the user and keep things in sync that way or if I need to look at approaching that call site differently. | |
| 16:47:45 | cardoe | It's a change to nova/compute/manager.py either way. | |
| 16:47:54 | Uggla | which is 986674: ironic: Abort build on fatal image validation errors | https://review.opendev.org/c/openstack/nova/+/986674 right ? | |
| 16:48:05 | cardoe | Yes | |
| 16:48:26 | cardoe | ah no | |
| 16:48:27 | cardoe | Sorry | |
| 16:48:38 | cardoe | That's to not try to build over and over if the image is bad. | |
| 16:49:09 | cardoe | I linked the wrong review to this. | |
| 16:49:36 | Uggla | anyway the above patch is in the pipe now thanks to gibi. | |
| 16:49:40 | cardoe | Thank you. | |
| 16:49:53 | cardoe | I'll come back with better details next week. I've held you all up long enough. | |
| 16:50:13 | Uggla | thanks cardoe. | |
| 16:50:23 | Uggla | moving on next topic | |

| 16:52:54 | Uggla | gibi, yeah I know about them. That's my joker. | |
| 16:53:01 | gibi | ;) | |
| 16:53:43 | Uggla | btw I had a fs full on the box collecting the stats, so the measurement stopped for several days. | |

| 16:54:20 | gibi | Uggla: you need to migrate to the cloud with infinite disk :D | |
| 16:54:23 | Uggla | nothing on the agenda, but if someone wants to discuss something in the latest mn | |
| 16:56:05 | Uggla | so if nothing else, I think we are good. | |
| 16:56:10 | gibi | thanks folks | |
| 16:56:30 | Uggla | Time to close, thanks for joining this meeting. Have a nice day/evening and see you next week. | |

| 16:52:59 | dansmith | bauzas: I think you might be a good person for this ^ I think Uggla and gmaan will be okay with this revision as they have both reviewed before | |
| 16:53:01 | dansmith | it's very simple :) | |
| 16:53:40 | bauzas | I'll try to look at it but I'm burned :( | |
| 16:53:59 | Uggla | dansmith, no I'm not ok, because you don't want to have fn tests. :) (just kidding) | |
| 16:54:08 | dansmith | Uggla: I added | |
| 16:55:13 | Uggla | dansmith, oh, so it is because I did not see the latest rev yet. But more seriously the spec is IMHO good. | |
| 16:56:45 | dansmith | bauzas: perhaps an easy spec for your morrow | |

| 08:34:45 | tafkamax | Hi, we have a question regarding live-migrate. Why do some nodes live-migrate really fast and some take many minutes up to 20 or so. | |
| 08:35:11 | tafkamax | I know it copies over RAM. But an VM with 8gb took many minutes and a vm with 24gb took 40 seconds or so. | |
| 08:35:15 | tafkamax | It feels very random. | |
| 08:39:59 | tafkamax | Where can I look for how this works and I can find a deterministic way to see why it varies so much? | |

| 13:46:36 | tafkamax | hi nova gurus. I am reading about live migration. Would you recommend setting libvirt.live_migration_permit_auto_converge to true or live_migration_permit_post_copy | |
| 13:46:36 | tafkamax | Both are not silver bullets, but i would like to know you guyses experiences in the wild. | |
| 13:46:56 | tafkamax | we have not gotten live migration timeouts | |
| 13:46:56 | tafkamax | but some of them take a long time | |
| 13:53:23 | sean-k-mooney | tafkamax: i generally recoemment prefering post copy over auto converge | |
| 13:53:37 | sean-k-mooney | if you enable both that is what libvirt will do internally | |
| 13:54:06 | tafkamax | ok, i read that in the docs that post-copy seems to be preferred | |
| 13:54:25 | sean-k-mooney | tafkamax: if you have a new enough nova you can also enabel multile tcp connection for live migration which is you pair that with a high bandwith nic helps alot | |
| 13:54:38 | sean-k-mooney | they are technially for 2 diffent things | |
| 13:54:53 | sean-k-mooney | post-copy is for memory bound vms which is typiclly the main issue | |
| 13:55:15 | sean-k-mooney | auto converge is a diffent aprpoch to the same problem where the vm is paused for longer and longer downtimes | |
| 13:55:29 | sean-k-mooney | basiclly to prevent ti form dirting the memory in the first place | |
| 13:55:59 | sean-k-mooney | but post-copy has much lower guest performance impact | |
| 13:56:09 | tafkamax | ok thanks for the info. will look into the tcp connection thing aswell | |
| 13:56:26 | sean-k-mooney | the tadeoff is that it extend the tiem where if there is a network interuption the guest can crash. | |
| 13:56:34 | sean-k-mooney | that is a very very rare event | |
| 13:56:46 | sean-k-mooney | but that is the reason its not on by default upstream | |
| 13:57:00 | sean-k-mooney | we have had post copy on by defualt in our downstream disto for a few years now | |
| 16:01:10 | opendevreview | Merged openstack/nova master: Drop Python 3.10 https://review.opendev.org/c/openstack/nova/+/986881 | |
| 18:20:27 | melwitt | elodilles: hey I saw that you had WIP to fix grenade-skip-level-always on stable/2025.1 but I noticed now the failure looks more fundamental i.e. "AttributeError: module 'setuptools.build_meta' has no attribute 'prepare_metadata_for_build_editable'. Did you mean: 'prepare_metadata_for_build_wheel'?" | |
