| 10:30:08 | cdent | ah, I hadnt understood you were using a custom resource class, that's an important bit of data. Do you have a log of the requests made to the placement service, it would be useful to see what the GET /allocation_candidartes query is | |
| 10:31:23 | cdent | pooja_jadhav: this bug may be related: https://bugs.launchpad.net/nova/+bug/1705231 | |
| 10:31:24 | openstack | Launchpad bug 1705231 in OpenStack Compute (nova) "Placement returns no allocation candidate for request that needs both compute resources and custom shared resources" [High,Fix released] - Assigned to Chris Dent (cdent) | |
| 10:43:25 | openstackgerrit | Stephen Finucane proposed openstack/nova master: conf: Correct documentation for '[pci] passthrough_whitelist' https://review.openstack.org/552874 | |
| 10:43:27 | stephenfin | lyarwood, sean-k-mooney: ^ | |
| 10:43:36 | stephenfin | I'll probably look for that to be backported if all is ok | |
| 10:46:11 | lyarwood | stephenfin: cool yeah that would be great, will need a bug if you have time, happy to quickly write one if not, I did mean to do this yesterday :| | |
| 10:47:19 | stephenfin | lyarwood: I'm working on the NUMA-aware vSwitch spec this morning, so if you're happy to write up said bug I'd appreciate it :) | |
| 11:39:05 | gibi | afternoon nova | |
| 11:39:48 | gibi | cdent: thanks for the placement doc update, I +2d it | |
| 11:57:05 | openstackgerrit | Merged openstack/nova master: Update contributor/placement.rst to contemporary reality https://review.openstack.org/552860 | |
| 12:27:35 | artom | bauzas, sahid, could you take a look at https://review.openstack.org/#/c/552722/ when you get a chance? It's the infamouse live migration with CPU pinning spec | |
| 12:27:56 | artom | sahid, you weren't at PTG, but we basically agreed to start over, with a spec, since Nikola's patch is too hard to review/merge at this point | |
| 12:28:21 | artom | jaypipes, ^^ dunno if you're around this early, but your input would be appreciated as well | |
| 12:36:07 | openstackgerrit | Nguyen Hai proposed openstack/nova-specs master: Enhance nova-specs webpage and clean up repo https://review.openstack.org/551802 | |
| 12:46:05 | jaypipes | artom: yep, will look shortly. | |
| 12:46:11 | jaypipes | thx for the heads up | |
| 12:47:14 | artom | jaypipes, cheers :) | |
| 13:11:09 | openstackgerrit | Eric Fried proposed openstack/nova master: placement: generation in provider aggregate APIs https://review.openstack.org/548249 | |
| 13:11:10 | openstackgerrit | Eric Fried proposed openstack/nova master: Stop assuming initial provider generation is 0 https://review.openstack.org/548975 | |
| 13:11:10 | openstackgerrit | Eric Fried proposed openstack/nova master: placement: Return new provider from POST /rps https://review.openstack.org/548934 | |
| 13:12:01 | jaypipes | efried: ^ that ready to go now? | |
| 13:12:09 | efried | jaypipes: First two, yes. | |
| 13:12:17 | efried | jaypipes: Quick, before edleafe's! | |
| 13:22:12 | edleafe | efried: no rush, working on alex_xu_'s comments | |
| 13:44:55 | alex_xu_ | edleafe: the only help I can give is to review efried's patch :) | |
| 13:45:04 | efried | hah! | |
| 13:49:18 | sar | Shouldn't there be a line such as this? : new_cinfo['volume_id'] = save_volume_id | |
| 13:49:18 | sar | So I had an issue where i couldn't delete an instance attached to a previously migrated volume. I get an error where it says it can't find the volume id. Turns out it doesn't update the volume_id in the json stored in block_device_mapping during volume migration. Can someone help me verify if this can be considered a bug? See around line 5656 here: https://git.openstack.org/cgit/openstack/nova/tree/nova/compute/manager.py | |
| 14:01:49 | edleafe | alex_xu_: should have an update soon. Until then, have at efried! | |
| 14:04:01 | mriedem | gibi: i'm going through https://review.openstack.org/#/c/502306/ if you want to hold off on updating it | |
| 14:04:56 | cdent | thanks jaypipes for saying what you did on the low-level cache spec | |
| 14:05:41 | jaypipes | cdent: yw | |
| 14:06:16 | cdent | I tried to read that whitepaper that's reference before I made a judgement and dissolved in a sea of acronyms | |
| 14:06:38 | cdent | but my gut reaction was "oh, you've got to be kidding me" | |
| 14:10:21 | openstackgerrit | Dan Smith proposed openstack/nova master: Add --by-service to discover_hosts https://review.openstack.org/552691 | |
| 14:15:46 | stephenfin | jaypipes: Low-level cache spec? | |
| 14:17:23 | jaypipes | stephenfin: https://review.openstack.org/#/c/502575/1/specs/pike/approved/cache-as-a-resource-with-rdt.rst@101 | |
| 14:18:09 | stephenfin | eew | |
| 14:18:13 | stephenfin | I change my mind | |
| 14:18:14 | dansmith | I'm going tp propose a spec soon to let you reserve a single byte of physical memory | |
| 14:18:20 | dansmith | hope that's cool | |
| 14:18:26 | jaypipes | dansmith: totes. go for it. | |
| 14:18:29 | dansmith | I've always been partial to memory location 0xdeadbeef | |
| 14:18:35 | jaypipes | dansmith: a single bit would be better, though. | |
| 14:18:35 | mriedem | jaypipes: just abandoned that spec - it was still targeting pike | |
| 14:18:38 | dansmith | and I desire my byte to be stored there | |
| 14:19:07 | ShilpaSD | stephenfin: Hi | |
| 14:19:14 | stephenfin | ShilpaSD: o/ | |
| 14:19:45 | ShilpaSD | stephenfin: Had one query on same topic what we discussed yesterday | |
| 14:19:58 | ShilpaSD | stephenfin: Instead of doing changes in manager to update access URL, can we add the url in novncproxy_base_url | |
| 14:19:58 | mnaser | logic | |
| 14:19:58 | mnaser | so i was working with the ODL folks and it looks like https://review.openstack.org/#/c/542738/ has their vif plugging. i dug in deeper and it looks like the unplug operation in os_vif with ovs is noop (so odl never really sees the port unplugged to change state) and then when the server is started again, it expects a network-vif-plugged event which never comes because the port is already plugged based on odl's | |
| 14:20:13 | mnaser | as this is being backported, it's breaking branch by branch unfortunately | |
| 14:20:24 | ShilpaSD | stephenfin: novncproxy_base_url=http:// |
|
| 14:21:06 | mnaser | unfortunately the port type is still 'ovs' when using ODL.. should the fix be making os_vif actually unplug things rather than noop? | |
| 14:21:40 | jaypipes | mnaser: I will take a look at it as soon as I'm done with the cyborg demo. | |
| 14:22:08 | mnaser | jaypipes: cool, thank you, i spent a lot of time digging around so i can point to a few things i've seen | |
| 14:22:54 | jaypipes | cool | |
| 14:26:20 | Kevin_Zheng | mriedem Hi saw you guys were talking about the quota issue yesterday, any conclusion? | |
| 14:26:42 | mriedem | Kevin_Zheng: no, just that it's still a problem | |
| 14:26:43 | openstackgerrit | Balazs Gibizer proposed openstack/nova-specs master: Network bandwidth resource provider https://review.openstack.org/502306 | |
| 14:26:53 | gibi | mriedem: sorry | |
| 14:26:54 | mriedem | efried: is there a spec or talk about adding a generation to https://developer.openstack.org/api-ref/placement/#update-allocations ? | |
| 14:26:59 | mriedem | gibi: ! | |
| 14:27:00 | gibi | mriedem: I just saw your ping | |
| 14:27:25 | gibi | mriedem: I promise I will read your comments even if it is on older ps | |
| 14:27:33 | mriedem | well ok then | |
| 14:28:56 | mriedem | efried: oh i guess there is an optional generation in PUT /allocations/{consumer_id} in 1.12 | |
| 14:28:57 | mriedem | so nvm | |
| 14:29:00 | gibi | mriedem: sorry. I will not be available until Monday (national holiday in Hungary) and I have to leave soon | |
| 14:29:07 | Kevin_Zheng | mriedm OK, I will be intrested if we dicide to fix it | |
| 14:29:08 | mriedem | np | |
| 14:29:24 | mriedem | Kevin_Zheng: melwitt sounded semi interested in fixing it, so probably want to talk to her | |
| 14:29:50 | Kevin_Zheng | Cool, good to know | |
| 14:30:23 | efried | mriedem: No, there's nothing. | |
| 14:30:39 | mriedem | efried: so https://developer.openstack.org/api-ref/placement/#request-microversions-1-12 is wrong? | |
| 14:31:28 | Kevin_Zheng | gibi, I have a quick question about versioned notification | |
| 14:31:39 | mriedem | https://github.com/openstack/nova/blob/master/nova/api/openstack/placement/schemas/allocation.py#L85 | |
| 14:31:46 | efried | It's ignored | |
| 14:32:00 | efried | generation (Optional)bodyintegerA consistent view marker that assists with the management of concurrent resource provider updates. The value is ignored; it is present to preserve symmetry between read and write representations. | |
| 14:32:01 | mriedem | oh gdi | |
| 14:32:24 | mriedem | ok, well, probably going to be important when both nova and neutron are changing allocatoins for the same consumer | |
| 14:32:53 | Kevin_Zheng | gibi, I saw that InstanceActionPayload is a parent object of alot other payload objects, and seems some of the child object also got version bump when the parent object got bumped? | |
| 14:33:08 | efried | mriedem: Yes. We talked about it in Dublin. On Wednesday IIRC. And agreed to add a generation field to the allocations table. jaypipes probably has more of it in his head. Not sure who's on the hook to do the spec/work. | |
| 14:33:18 | mriedem | Kevin_Zheng: yes that's not new | |
| 14:33:23 | gibi | Kevin_Zheng: if you add something to the parent then that will appeare in the children payloads therefore you need the bump | |
| 14:33:24 | mriedem | you'll have to update all of the children | |
| 14:33:37 | Kevin_Zheng | OMG | |
| 14:33:43 | Kevin_Zheng | so many children | |
| 14:33:52 | mriedem | c'mon | |
| 14:33:56 | mriedem | climb that mountain | |
| 14:34:12 | gibi | Kevin_Zheng: the parent-child relationship is not visible in the serialized payload, as it only contains the child class name | |
| 14:34:38 | gibi | Kevin_Zheng: therefore the version of the child should reflect the overall structure | |
| 14:35:06 | Kevin_Zheng | gibi ack | |
| 14:35:30 | gibi | Kevin_Zheng: dont worry I think the unit test will catch if you miss some of those children | |
| 14:35:53 | Kevin_Zheng | mriedem you got trainning too, I thought it was just for us LOL | |
| 14:36:38 | gibi | Kevin_Zheng: as the signature of the children classes will change if you add a field to the parent | |
| 14:37:09 | Kevin_Zheng | gibi, yeah thats true | |
| 14:37:38 | openstackgerrit | Ed Leafe proposed openstack/nova master: Add 'member_of' param to GET /allocation_candidates https://review.openstack.org/552098 | |
