11:29:32 cdent bauwser: I changed that bug back to triaged. I agree with you that the solution they've used may not be optimal, but there _is_ a bug
11:29:52 cdent they want to be able to express >1 location of config file, which is a normal thing for something that uses oslo_config
11:34:44 sdague sfinucan: on https://review.openstack.org/#/c/472266 - I think you are right, we can't remove that bit in Pike, it's going to need a db migration
11:35:24 sdague however, this is bad enough that I think we want to get this in and backported asap, as the failure mode is "my guests can't start after upgrade"
11:35:31 sdague which is about as bad a failure mode as we have
12:32:46 kashyap artom: I saw the ping from here, but didn't completely read-through the scrollback
12:32:49 kashyap Was there a question for me?
12:59:43 artom kashyap, err, I think it was last night when we were talking about transient vs. persistent domains
12:59:55 artom Neither of us was 100% sure of what each of those implies
13:00:03 kashyap artom: Yeah, sorry should've mentioned it was last night
13:00:17 artom So we thought of you :)
13:01:00 kashyap For a transient domain, the guest does not stay up across reboots / shutdown
13:01:17 kashyap I.e. you'll lose the guest XML definition
13:01:23 kashyap You might wonder where it would be useful
13:01:53 kashyap artom: An example that comes to mind is the blockCopy() API
13:02:13 kashyap Where you have to temporarily make a guest transient, for it to complete
13:02:30 kashyap Because -- a live block copy job cannot last across reboots
13:02:35 kashyap A simple test -- https://kashyapc.fedorapeople.org/virt/temp/live-blockcopy-quick-test.txt
13:03:54 bauwser sdague: should we maybe stop to ask users to provide a bug report when they have a HTTP500 ?
13:03:59 openstack Launchpad bug 1696972 in OpenStack Compute (nova) "host type 'm1.nano' not found when lanch instance" [Undecided,New]
13:03:59 bauwser for example, see https://bugs.launchpad.net/nova/+bug/1696972
13:04:00 kashyap artom: Also, from Nova code, in libvirt/driver.py (in _swap_volume(), for blockRebase() which is the same API:
13:04:03 kashyap try:
13:04:05 kashyap # NOTE (rmk): blockRebase cannot be executed on persistent
13:04:08 kashyap # domains, so we need to temporarily undefine it.
13:04:11 kashyap # If any part of this block fails, the domain is
13:04:13 kashyap # re-defined regardless.
13:04:16 kashyap if guest.has_persistent_configuration():
13:04:18 kashyap support_uefi = self._has_uefi_support()
13:04:19 bauwser sdague: we have lots of bug reports that are possibly a configuration problem
13:04:21 kashyap guest.delete_configuration(support_uefi)
13:04:50 sdague bauwser: sure
13:05:21 sdague bauwser: I'd be fine dropping that message in the 500 payload
13:05:44 bauwser okay
13:06:03 sdague also, someone with traslated logs!
13:06:10 sdague that's the first time I've seen that in practice
13:06:33 artom kashyap, so would I be correct in understanding that transient domains came about more as a technical necessity of long running operations that cannot last across reboots rather than as a user-facing feature?
13:07:04 sdague bauwser: that being said, it would be nice to actually catch these misconfiguration items and be more explicit about them
13:07:19 bauwser sdague: agreed, I'll add a better exception
13:07:22 bauwser for that
13:07:30 sdague bauwser: ok, cool
13:07:31 kashyap artom: Almost correct. It's also useful for "user-facing" feature in the sense that -- if you're testing something w/ libvirt, and don't want to clean up the guests your self, you can use transient domains
13:07:34 artom So what happens if the host dies while such an operation is happening? It aborts, obviously, the transient domain is lost, but the persistent domain, the one without the operation going on, is saved, and comes back after the host recovers?
13:08:02 sdague bauwser: while you are looking at things - https://review.openstack.org/#/c/472266/ really feels like we should get it in soon
13:08:12 sdague that's the fail to start instances after upgrade bug
13:08:19 bauwser sdague: roger.
13:10:57 sfinucan sdague: That sounds good to me. +Wd now
13:10:59 openstackgerrit falseuser proposed openstack/nova master: Clear instance root_device_name in rebuild operation https://review.openstack.org/464991
13:11:34 bauwser oh man, +W'd duplicated :)
13:11:43 bauwser shit.
13:40:58 sdatko hello
13:42:01 sdatko tiny question: nova.db.sqlalchemy.models.InstanceTypeExtraSpecs vs nova.db.sqlalchemy.api_models.FlavorExtraSpecs
13:43:31 openstackgerrit Sylvain Bauza proposed openstack/nova master: Provide a better log when api_servers is unset https://review.openstack.org/472685
13:43:33 sdatko for first one there is note about being deprecated; however, when performing context.session.query(models.InstanceTypeExtraSpecs) i can see results, while for context.session.query(api_models.FlavorExtraSpecs) i receive empty array
13:43:44 bauwser sdague: see https://review.openstack.org/472685 for the api_servers opt
13:44:21 mriedem sdatko: the former is in the cell database (nova db), the latter is in the api db (nova_api db), flavors were moved from the cell to the api db a few releases ago
13:44:24 mriedem mitaka i think
13:44:49 sdatko hmm
13:45:07 sdatko ok, to be honest, i just played and created some tests
13:45:30 sdatko in those tests, i used nova.db.sqlalchemy.api.flavor_create()
13:45:50 sdatko this one is outdated?
13:46:22 mriedem you shouldn't be playing around with the db apis directly
13:46:49 mriedem everything goes through nova.objects.flavor.Flavor
13:47:58 sdatko ouuu
13:48:28 sdatko my fault then
13:48:33 sdague bauwser: I would honestly throw an exception there as well
13:48:44 sdatko thanks mriedem
13:48:45 sdague the rest of the code is going to fail with a different exception later
13:49:04 bauwser sdague: fine, I was just thinking of leaving the glanceclient providing its own exception
13:49:14 mriedem sdague: bauwser: here is the ocata backport for that rbd thing https://review.openstack.org/#/c/472687/
13:49:20 mriedem sdatko: yw
13:49:43 bauwser mriedem: hold my beer
13:50:04 sdague mriedem: probably should trigger a release off of that on stable as well
13:50:53 bauwser mriedem: in other words, ping me when master is merged
