22:56:37 mriedem ok, it would be nice if someone else from the red hat team could recreate and verify the fix before we actually eol newton, because while red hat customers will get the fix in newton, people consuming from upstream stable wouldn't, and that sucks
22:57:20 clarkb mriedem: you should ping tony as the eol is happening right now I think
22:57:26 clarkb tonyb: ^ you have been pinged
22:57:42 mriedem clarkb: see sbove
22:57:45 mriedem *above
22:57:52 clarkb oh perfect
22:59:33 tonyb clarkb: It is but nova has been excluded as it has a pending release request ... it wasn't strictly needed but allows thise these shenanigans ;P
23:00:02 tonyb mriedem: I'll look at it after I've done the EOL thing as I don't want to mess that up
23:00:28 melwitt mriedem: yes, understood. I'll see what I can do

04:16:41 masber good afternoon all, I just deployed openstack but nova gives errors when deploying a new instance. any thoughts? http://paste.openstack.org/raw/624553/
04:25:10 masber apologise, the previous paste had the last part of the logs missing, this is the end of it http://paste.openstack.org/raw/624556/

07:04:38 namnh lyarwood: hi lee, are you free?. could i ask you a question. i saw you have a spec in tripleo about fast-forward-upgrade. Basically, in my inderstanding, FFU in tripleo is offline-upgrade automatically (roles ansible will do this) instead of manual, is that right?

07:39:07 jianghuaw bauzas, looks good. Thanks.
07:39:10 naichuans bauzas: thank you, will check it
07:52:15 gibi good morning nova
08:25:44 openstackgerrit Yikun Jiang proposed openstack/nova master: [WIP] Add migration db and object pagination support. https://review.openstack.org/514904
08:42:54 johnthetubaguy gibi: bauzas: not sure who to ask at this time of day, but either of you remember when cell_mappings get deleted? I had assumed when you delete the instance, but I guess you leave it because its a soft_delete?
08:50:43 jmccarthy Any pointers about how nova adjusts devices that are created (as seen in instance dumpxml) when creating instances on different hypervisors ?
08:50:56 jmccarthy I have some where the console works (but not console log) and some the other way around
09:06:48 gibi johnthetubaguy: sorry I have no idea when we delete cell_mappings
09:07:10 johnthetubaguy jmccarthy: not sure if this helps, but this is part of the create instance code: https://github.com/openstack/nova/blob/master/nova/virt/libvirt/driver.py#L2806
09:07:22 gibi johnthetubaguy: sitting on a meeting right now, I can try to look at the code after that
09:07:40 johnthetubaguy gibi: thanks, I think it might be never, which seems like a poor choice
09:16:17 johnthetubaguy gibi: I just remembered about doing a GET on a deleted instance, for admins
09:17:16 johnthetubaguy gibi: but we don't have an archive deleted rows thing for the API DB...
09:17:29 johnthetubaguy (as there is no soft delete)
09:26:54 jmccarthy johnthetubaguy: Thanks !
09:48:56 openstackgerrit Yikun Jiang proposed openstack/nova master: [WIP] Add migration db and object pagination support. https://review.openstack.org/514904
10:04:05 openstackgerrit sahid proposed openstack/nova master: libvirt: disconnect volume from host during detach https://review.openstack.org/515008
10:09:27 gibi johnthetubaguy: do you refert to the InstanceMapping class when you say cell_mappings?
10:10:03 johnthetubaguy gibi: sorry, I meant instance_mappings
10:13:51 gibi johnthetubaguy: I found some cleanup here https://github.com/openstack/nova/blob/df9fbbfec97a1ce13364d025bcd66621725bb7e4/nova/compute/api.py#L1200
10:14:29 gibi johnthetubaguy: but I guess this is just the case when nova fails to build the instance
10:15:15 johnthetubaguy gibi: looks that way
10:15:37 johnthetubaguy gibi: I suspect its because you can GET for a delete instance, so you can only delete once you do a hard delete in the child cell
10:16:04 johnthetubaguy gibi: thanks for looking into that for me though, backs up what I was thinking
10:19:45 gibi johnthetubaguy: as I see there is no way to soft delete an InstanceMapping in the api db so your observation makes sense
10:20:34 johnthetubaguy yeah, no soft delete in any of the api_db, I think
10:21:05 gibi johnthetubaguy: does the archiving process moves the instance mapping from the production table to the shadow table?
10:21:12 gibi johnthetubaguy: that could be a way to clean up
10:22:34 johnthetubaguy but that util doesn't have access to the api_db, generally
10:23:50 johnthetubaguy oh, wait, I was thinking about the instance moving to a shadow table, I didn't think we did shadow tables in the API db
10:24:13 johnthetubaguy I saw we had a non-shadow table archive, but I must have got mixed up
10:24:28 johnthetubaguy s/saw/swore/
10:26:42 gibi johnthetubaguy: OK then I conclude that nova doesn't delete the instance mapping at all
10:27:08 johnthetubaguy gibi: thanks, I thought I was going a bit mad not being able to track that down
10:37:27 masber good afternoon, I am having an issue with nova where my instances are failing during building process
10:39:40 masber this is the error I can see running openstack server show command http://paste.openstack.org/raw/624579/
10:46:43 johnthetubaguy masber: if you look at the original log, it has a request-id in there, you will want to search for other logs with that id in it, that will show you why you hit that error
10:54:04 masber johnthetubaguy, is this what you mean? http://paste.openstack.org/show/624582/
11:05:10 johnthetubaguy masber: maybe, but I suspect you need logs from nova-conductor and other services, using that request-id (although I don't see the no valid host error log in there)
11:05:35 masber oh ok
11:05:40 masber I just checked the scheduler
11:05:53 masber let me see other log files
11:05:53 johnthetubaguy masber: should really move to the #openstack channel I guess, its more operator focused than dev
11:09:08 masber johnthetubaguy, ok I got a permission denied http://paste.openstack.org/raw/624585/
11:09:53 johnthetubaguy masber: ah, cool, that sounds like the root cause
11:10:48 masber how weird
11:11:52 ttsiouts hey guys! I started investigating this bug report: https://bugs.launchpad.net/nova/+bug/1644457. was there a decision that a user's keypairs in_use should not be counted by the cli: nova quota-show --user --detail?
11:11:53 openstack Launchpad bug 1644457 in OpenStack Compute (nova) "keypair quota error" [Medium,Confirmed] - Assigned to Theodoros Tsioutsias (ttsiouts)
11:29:54 efried masber You'll probably want to check your compute logs. Is the compute service started?
11:40:26 efried bauzas naichuans https://review.openstack.org/#/c/514942/ ++! I was poring over this code last night and it made me realize how important this is going to be.

12:13:58 efried cdent dansmith Took the liberty of fixing that nit since Jay's still out and the patch is now the first one in the series ^
12:14:19 cdent ✔
12:20:14 cdent efried: on the vgpu stuff, I get that you want to be able to change stuff you can’t express elsewhere, and that we want that
12:20:38 cdent but doesn’t it also make it so the flavor can express VCPU: 2 and then the extra spec can say VCPU: 4
12:21:00 efried cdent That was already the case, intentionally. The extra spec overrides.
12:21:23 cdent I thought the previous behavior was only that the extra spec could set to 0?
12:21:27 efried cdent This was done so that we could move toward the extra spec resources being the single source of truth for all resource requests.
12:21:36 efried uh, stand by...
12:21:50 cdent (for _standard_ classes)
12:22:18 efried cdent No, you could override too.
12:22:41 cdent Basically what I’m trying to understand is if we are making it so there are now two places to do things, and if so, is the plan to end up on only one. If there is, cool.
12:22:42 efried Setting to 0 would remove it. Presumably this is so you could e.g. provide disk resource from somewhere else, but you can't create a flavor with disk 0.
12:23:52 cdent I hope some day we will just destroy flavors as an internal concept and they will only be a UI thing.
12:23:53 efried cdent The plan is to be able to express all resources from one place. We didn't want to (couldn't) do that by adding every standard and custom resource class to the main flavor object. So we want to do it via specific namespacing in the extra_specs because it's a freeform grab-bag.
12:24:44 efried cdent I don't know what the ultimate fate of the flavor object will be. But I don't disagree that it's kind of a mess atm.
