| 12:13:12 | openstackgerrit | Merged openstack/nova master: Docs: Add Placement to Nova system architecture https://review.openstack.org/584338 | |
| 12:20:48 | openstackgerrit | Liam Young proposed openstack/nova master: Remove Neutron MetaAPIProxy from cellsv2-layout https://review.openstack.org/588525 | |
| 12:30:53 | openstackgerrit | Surya Seetharaman proposed openstack/nova master: Cleanup comp_node, res_prov, services, aggregate_hosts during cell deletion https://review.openstack.org/546660 | |
| 12:40:26 | mriedem | cfriesen: what was the reason for needing a POST /os-services API to create nova-compute services on a given host? https://github.com/starlingx-staging/stx-nova/commit/71acfeae0d1c59fdc77704527d763bd85a276f9a#diff-f3afe2522f9c92f5705f0ff5cf343865R246 | |
| 12:40:36 | mriedem | which is also, btw, not multi-cell aware since it doesn't rely on the host mapping | |
| 12:44:49 | mriedem | sean-k-mooney: check this out https://github.com/starlingx-staging/stx-nova/commit/71acfeae0d1c59fdc77704527d763bd85a276f9a#diff-99e4b3f7232bf35155ff8b590b0ea589R44 | |
| 12:47:18 | sean-k-mooney | mriedem: clicking but not sure i want too | |
| 12:47:30 | sean-k-mooney | haha | |
| 12:48:23 | sean-k-mooney | mriedem: that in the api. that is not a bad idea to be honest | |
| 12:49:12 | sean-k-mooney | mriedem: we dont document in the api that when using the libvirt dirview we detach all pci/sriov device on suspend which is hostile to a guest application that was uing them | |
| 12:49:26 | sean-k-mooney | pause would not detach the devices. | |
| 12:51:06 | openstack | Launchpad bug 1785246 in OpenStack Compute (nova) "Compute API reference should describe pause and suspend operations" [Medium,Confirmed] | |
| 12:51:06 | mriedem | sean-k-mooney: i know https://bugs.launchpad.net/nova/+bug/1785246 | |
| 12:51:15 | sean-k-mooney | mriedem: we likely can do this where i wanted too in the snapshot case after talking to dansmith due to concern about data curroption by not flushing buffers but this seams ok | |
| 12:51:44 | sean-k-mooney | ya i was think about that yesterday after we were talking about it. | |
| 12:52:01 | mriedem | windriver could have just disabled the suspend/resume apis with policy | |
| 12:52:07 | mriedem | rather than change the behavior | |
| 12:52:24 | sean-k-mooney | its an impentation detail of the libvirt driver im not sure we should be leaking it through the api | |
| 12:52:39 | sean-k-mooney | that said we should document it | |
| 12:53:34 | bauzas | mriedem: hola | |
| 12:53:59 | sean-k-mooney | fried_rice: any idea if the ibm drivers detach pcidevices from the guest on suspend | |
| 12:54:13 | bauzas | mriedem: I was thinking on cherry-picking https://review.openstack.org/#/c/584204 (I mean, the series) to Queens | |
| 12:54:38 | bauzas | mriedem: you okay with it ? | |
| 12:55:25 | fried_rice | sean-k-mooney: I would only be able to answer for PowerVM, and... It's possible suspend is an operation we don't support. /me checks support matrix... | |
| 12:55:45 | sean-k-mooney | fried_rice: im looking at the intree driver now. | |
| 12:55:51 | mriedem | bauzas: no | |
| 12:56:02 | mriedem | RequestSpec.is_bfv is an rpc api bump | |
| 12:56:05 | mriedem | so not backportable | |
| 12:56:11 | bauzas | oh rightg | |
| 12:56:18 | mriedem | dansmith and i talked about that while he was writing the patch | |
| 12:56:56 | sean-k-mooney | mriedem: i might start working on that docs bug by the way but ill need stephenfin ect to check it since my written expression is not always well valid english :) | |
| 12:57:06 | fried_rice | sean-k-mooney: https://docs.openstack.org/nova/latest/user/support-matrix.html#operation_suspend_driver_powervm | |
| 12:57:24 | mriedem | sean-k-mooney: sure | |
| 12:57:42 | mriedem | i'm also not saying we should copy the libvirt description of those operations into the api, | |
| 12:57:47 | mriedem | if it's not the same behavior across virt drivers | |
| 12:59:23 | sean-k-mooney | mriedem: i agree but we should likely add a note for the different backends. https://docs.openstack.org/nova/latest/user/support-matrix.html#operation_suspend should proably have a note too | |
| 13:00:31 | bauzas | mriedem: for some reason, I missed https://review.openstack.org/#/c/580720/ in the series | |
| 13:00:35 | bauzas | my bad | |
| 13:08:38 | sean-k-mooney | interesting... the xenapi appears to just suspend. both hyperv and vspher end up delegating to there repective hyperviors suspend as a result this apears to only be a thing for libvirt. | |
| 13:12:24 | fried_rice | Anyone from HyperV around? | |
| 13:17:13 | sean-k-mooney | fried_rice: i guess not | |
| 13:17:26 | sean-k-mooney | brb going for lunch/coffee | |
| 13:17:28 | fried_rice | doesn't matter, I found what I needed. | |
| 13:19:29 | openstackgerrit | Merged openstack/nova master: Scrub hw:cpu_model from API samples https://review.openstack.org/588371 | |
| 13:20:48 | fried_rice | stephenfin: Any justification for something like this https://review.openstack.org/#/c/588422/ ? | |
| 13:27:25 | stephenfin | fried_rice: Not that I'm aware of, anyway | |
| 13:27:35 | stephenfin | Purely a nice to hav | |
| 13:27:57 | fried_rice | stephenfin: ight, thanks for the look. I'm not opposed to approving the thing once they fix it, I guess. | |
| 13:28:05 | stephenfin | likewise | |
| 13:28:13 | fried_rice | Rather than saying it's a fin u cannot do (hint) | |
| 13:28:25 | finucannot | noted | |

| 14:26:12 | openstack | Launchpad bug 1785235 in OpenStack Compute (nova) "metadata retrieval fails when using a global nova-api-metadata service" [Undecided,In progress] - Assigned to Liam Young (gnuoy) | |
| 14:26:12 | melwitt | dansmith: do you understand this bug? says guests can't retrieve metadata from the metadata API with multiple cells https://bugs.launchpad.net/nova/+bug/1785235 cc gnuoy | |
| 14:27:26 | dansmith | well, I understand the words in the bug | |
| 14:27:30 | melwitt | I had thought guests retrieved metadata over http, not the MQ | |
| 14:27:31 | cfriesen | mriedem_afk: I think the idea was to allow a management layer to create a new compute node in the DB so that we can "disable" it, set up system-generated host aggregates, boot the node, do some health checks, then "enable" it once everything is ready. | |
| 14:27:46 | dansmith | I also understand that I'm going to -2 the code change | |
| 14:27:47 | dansmith | melwitt: of course they do, | |
| 14:27:49 | melwitt | okay. I didn't understand either | |
| 14:28:03 | dansmith | but they're saying that metadata service then doesn't hit the right db as a result | |
| 14:28:12 | gnuoy | yep | |
| 14:28:26 | melwitt | oh, I see | |
| 14:29:39 | melwitt | so, this method, or another one that we missed cell targeting in? https://github.com/openstack/nova/blob/master/nova/api/metadata/base.py#L677 | |
| 14:30:04 | dansmith | melwitt: L692 | |
| 14:30:46 | melwitt | right | |
| 14:31:16 | melwitt | okay | |
| 14:31:17 | dansmith | commented | |
| 14:32:31 | gnuoy | dansmith, I see context.target_cell getting called and adding the cells mq and db endpoints to cctxt | |
| 14:32:33 | melwitt | cool thanks | |
| 14:32:50 | gnuoy | but when the request executes those endpoints are ignored | |
| 14:33:23 | dansmith | gnuoy: did you open this bug? | |
| 14:33:26 | gnuoy | I did | |
| 14:33:45 | dansmith | gnuoy: please show some logs and config | |
| 14:34:15 | gnuoy | sure | |
| 14:36:40 | dansmith | gnuoy: are you running a standalone metadata server with cmd/api_metadata ? | |
| 14:38:24 | gnuoy | I am running a standalone metadata server. I don't follow the second part of the question | |
| 14:39:08 | dansmith | gnuoy: okay I think I see what's going on and why you want to make the change you're making | |
| 14:39:22 | gnuoy | ah, cool! | |
| 14:39:37 | gnuoy | dansmith, that change was a starter for 10, I'm happy to update it | |
| 14:39:46 | dansmith | gnuoy: so there are two ways to run metadata, either part of the regular api with enabled_apis= | |
| 14:40:06 | dansmith | and then with the standalone cmd/api_metadata thing which just starts up a standalone metadata server | |
| 14:40:19 | dansmith | the latter always forces the indirection api into place, | |
| 14:40:33 | dansmith | which was really intended for the case where you're running metadata on each compute node | |
| 14:40:34 | gnuoy | yep, I saw that | |
| 14:40:48 | gnuoy | ah | |
| 14:40:59 | dansmith | for the global case, you really should be running the regular api server, and just not enable the osapi api if you want to only run metadata | |
