| 21:32:08 | spatel | i tried all option but getting same error | |
| 21:32:27 | spatel | now thinking to re-build it... | |
| 21:32:57 | spatel | when you said - you are getting that because you are livemigrating instance with a numa toplogy | |
| 21:33:11 | spatel | what does that means? | |
| 21:33:28 | sean-k-mooney | i assume you are getting that error becasue you tried to do a live migration | |
| 21:33:37 | spatel | if i have machine and i said live migrate, where numa comes in picture | |
| 21:33:39 | sean-k-mooney | if that is not the case how did you hit this issue | |
| 21:34:04 | sean-k-mooney | if your instance use hugepage or cpu pinning it will have a numa toplogy | |
| 21:34:19 | spatel | someone from my team trying to do and it endup in this situation, i have to talk to him to get full picture | |
| 21:35:29 | spatel | oh.. yes that instance had hugepage/cpu pinning | |
| 21:35:57 | spatel | you are saying we can't do live migration if instance has hugepage/cpu pinning? | |
| 21:36:01 | spatel | sean-k-mooney: ^ | |
| 21:36:18 | sean-k-mooney | technically it can work but its not properly supported by nova | |
| 21:36:31 | sean-k-mooney | we dont currently update teh xml when migrating | |
| 21:36:37 | sean-k-mooney | for live migrations | |
| 21:37:12 | sean-k-mooney | spatel: its a knwon issue that is being adressed by https://review.opendev.org/#/q/topic:bp/numa-aware-live-migration+(status:open+OR+status:merged) | |
| 21:38:36 | spatel | so it not merge yet? | |
| 21:38:41 | sean-k-mooney | cold migrations are supported but until ^ is implemented nova will not update teh libvirt xml and you can get that error amoung others | |
| 21:38:45 | sean-k-mooney | no its not | |
| 21:39:07 | sean-k-mooney | for stien we specifcialy disable live migration for instnace with numa toplogies | |
| 21:39:17 | sean-k-mooney | i think we started backporting that too | |
| 21:39:57 | spatel | oh! | |
| 21:40:04 | spatel | this is a big issue then.. | |
| 21:40:38 | spatel | how to migrate instance if my compute node is dead and all vm running on shared storage? | |
| 21:41:05 | sean-k-mooney | if the compute node is dead and the vms are using shared storage you should use evacuate | |
| 21:41:28 | spatel | hmm.. | |
| 21:41:30 | sean-k-mooney | it will rebuild the instance on another host | |
| 21:41:42 | sean-k-mooney | but you should only use evacuate if the instance is stopped | |
| 21:41:56 | spatel | what if i want to migrate specific vm ? any heck there? | |
| 21:42:28 | spatel | sean-k-mooney: so you are saying i can shutdown instance and do evaluate ? | |
| 21:42:30 | sean-k-mooney | evacuate works for a specifc vm | |
| 21:43:03 | spatel | This is very important information, i was totally not aware of it.. | |
| 21:43:55 | spatel | I need to make big banner now to tell everyone don't do live migration period.. | |
| 21:44:13 | sean-k-mooney | if you have not already read it the go to text on evacuate is http://www.danplanet.com/blog/2016/03/03/evacuate-in-nova-one-command-to-confuse-us-all/ | |
| 21:44:23 | sean-k-mooney | what release of openstack are you running | |
| 21:44:46 | spatel | my old cloud running on queens and new cloud i am build on stein | |
| 21:45:46 | sean-k-mooney | looks we have the config option on rocky https://github.com/openstack/nova/blob/stable/rocky/nova/conf/workarounds.py#L223 | |
| 21:46:58 | sean-k-mooney | ah we havnt merged https://review.opendev.org/#/c/629597/ | |
| 21:48:31 | spatel | hmm is it config option which i can turn on to protect from accident ? | |
| 21:48:47 | sean-k-mooney | spatel: live migration with hugepage works most of the time. cpu pinning is much less likely to work correctly | |
| 21:49:17 | sean-k-mooney | with that patch by default we will not allow instace with a numa toplogy to be live migrated | |
| 21:49:24 | sean-k-mooney | so its safe by default | |
| 21:49:26 | jaypipes | efried: ahoy! :) going well, ty! | |
| 21:49:39 | efried | good to hear | |
| 21:50:15 | spatel | sean-k-mooney: hmm we used both pinning/hugepage :) | |
| 21:51:10 | sean-k-mooney | :) yes. this si something we have wanted to fix for several relese. it will get done this cycle one way or another. | |
| 21:51:19 | sean-k-mooney | unfortuanetly its not backportable | |
| 21:52:19 | spatel | damn.. | |
| 21:52:36 | sean-k-mooney | jaypipes: life treating you well in aws land | |
| 22:07:00 | mriedem | efried: i did your deed | |
| 22:07:05 | mriedem | with lots of comments about why i didn't want to | |
| 22:07:27 | mriedem | also, i'll have to redo https://review.opendev.org/#/c/541420/ which is 3 months older than takashin's de-mox-ification | |
| 22:07:34 | efried | Thanks mriedem. You will be rewarded in the hereafter. | |
| 22:07:42 | mriedem | satan won't care about this | |
| 22:08:09 | efried | mriedem: tell it to review 666666 | |

| 22:48:28 | sean-k-mooney | efried: ^ | |
| 22:50:58 | sean-k-mooney | i need to rereview it after fully rereading the sev spec. while not contradictory i think it makes more change then required at least for a v1 | |

| 08:40:23 | lyarwood | yasemin: I've got no idea what `16.0.13` is but make sure you have https://review.opendev.org/#/q/Iae2962bb86100f03fd3ad9aac3767da876291e74 | |
| 08:43:04 | yasemin | <lyarwood> the bug is 2017. does it related to my problem ? | |
| 08:56:05 | lyarwood | yasemin: if you're using QEMU > 2.10 then maybe | |
| 08:56:51 | lyarwood | yasemin: `16.0.13` isn't a released version of openstack-nova upstream AFAICT, it should contain that patch as it was included in actual early releases but I obviously can't tell | |
| 08:57:23 | lyarwood | yasemin: feel free to open a bug https://launchpad.net/nova/ listing your versions of QEMU, Libvirt and where you got this version of openstack-nova. | |
| 09:36:12 | jrosser | lyarwood: i think that is the 16.0.13 release of openstack-ansible which pulls in this SHA of nova https://github.com/openstack/openstack-ansible/commit/f678b3d9a237a0cad229cad6cbc5fd9254b5a6f4#diff-78907cb9f0dc957a6642505f5b9c135cR150 | |
| 09:43:16 | lyarwood | jrosser: ack thanks | |

| 10:20:06 | kashyap | (Hope you had a good time) | |
| 10:20:23 | kashyap | The literal block, where do I put it on line-306? Why rST, why you do this to me... | |
| 10:20:34 | stephenfin | 306 needs to be indented more | |
| 10:20:54 | stephenfin | and 303 needs to take the form '(a)', I think | |
