14:57:15 openstackgerrit Balazs Gibizer proposed openstack/nova master: use already loaded BDM in instance.create https://review.openstack.org/483969
14:57:34 gibi mriedem: and here is the updated patch series ^^
14:58:54 jianghuaw sahid, The spec is focusing on how to populate the resource providers and their inventory for vGPU. And as there is problem to handle multiple vGPU types; so added a new option to restrict one resource provider can only supply one type of resources. So are you suggesting to make the implementation on the restriction be common; so it can be re-used for future similar features?
15:03:40 sahid jianghuaw: yes since that option looks really similair to the requierements for other kind of devices (sriov..) i think we could have just one, and have one implementation to parse it
15:06:09 openstackgerrit Brianna Poulos proposed openstack/nova master: Add trusted_certs to Instance object https://review.openstack.org/489408
15:06:09 openstackgerrit Brianna Poulos proposed openstack/nova master: Add trusted_certs to instance_extra https://review.openstack.org/457711
15:06:10 openstackgerrit Brianna Poulos proposed openstack/nova master: Add trusted_certificates to REST API https://review.openstack.org/486204
15:06:42 jianghuaw sahid, I thought the problem to be resolved by this option is specific for vGPU. One pGPU can support different sized vGPUs. different capacity for different size. If created one size/type of vGPU on a pGPU, it can't create other size/type of vGPUs.
15:06:55 jianghuaw For other devices, is there similar issue?
15:11:10 sahid jianghuaw: hum... operators are going to creates some kind (size/type) vGPUs, but then that is not dynamic so the option is just about to parse which vCPUs we want to expose to Nova, no?
15:12:42 jianghuaw yes, the option is to make the vGPU type be static on one compute node.
15:12:50 sahid so even if a pGPU support different kinds, we want first to "allocate" the kind we want and bzsically create a pool of media which will be exposed to Nova
15:13:07 sahid jianghuaw: yes so basically it's what we have for sriov
15:15:04 sahid jianghuaw: just put your thinking on the review and let see what other contributors think... my point is just to implement one thing which could work for mdev/sriov
15:15:19 jianghuaw It will pre-restrict the type; and only create a resource provider for this specific type.
15:15:35 mriedem gibi: ack
15:16:03 jianghuaw Sure. if that's true a common thing, we can consider to make it general. Thanks sahid.
15:17:00 openstackgerrit Merged openstack/nova master: use unicode in tests to avoid SQLA warning https://review.openstack.org/505198
15:21:48 tasker mriedem: it looks like https://bugs.launchpad.net/nova/pike/+bug/1717365 affects several different code paths in addition to just the one identified previously.
15:21:49 openstack Launchpad bug 1717365 in OpenStack Compute (nova) "binding:profile is None breaks migration" [Medium,In progress] - Assigned to Matt Riedemann (mriedem)
15:22:23 mriedem tasker: want to point those out in the review then?
15:22:30 tasker sure can.
15:22:54 tasker I'm going to be a bit blind ( not understanding all of nova ), but I'll identify all of the lines that could result in the same problem.
15:23:04 mriedem there was one other place i saw that it was not checked but i didn't think we could have a failure in the other location if we fixed the one spot you hit properly
15:23:55 tasker I just hit it in _update_port_binding_for_instance() during post-migration tasks.
15:26:20 mriedem tasker: here? https://review.openstack.org/#/c/504260/2/nova/network/neutronv2/api.py@2509
15:29:47 ratailor melwitt, Could you please have a look on https://review.openstack.org/#/c/504885/
15:31:57 melwitt ratailor: yeah, that's an old issue and I'm not sure where things landed as far as how to fix it. I don't remember us wanting to change the collation type of the column or if there was a reason we shouldn't. sdague might be able to recall past discussion on that
15:32:37 ratailor melwitt, Thanks, I will try to catch him tomorrow.
15:51:12 gibi mriedem: Is it OK to have the following small notification addition as a specless BP? https://blueprints.launchpad.net/nova/+spec/emit-service-create-notification
15:55:35 gibi cdent: have you seen my question in https://review.openstack.org/#/c/502155/5/nova/tests/functional/db/test_resource_provider.py@1522 ? I'm eager to approve your patch series
16:00:12 tasker mriedem: yes.
16:00:53 ratailor sdague, Could you please have a look on https://review.openstack.org/#/c/504885/
16:03:10 openstackgerrit Merged openstack/nova stable/pike: Set error state after failed evacuation https://review.openstack.org/504979
16:05:01 openstackgerrit Eric Fried proposed openstack/nova master: Nix warning about protocol-less glance api_servers https://review.openstack.org/505317
16:05:04 efried sdague ^
16:09:03 tasker mriedem: I'm having some browser troubles intercepting the "ctrl+s" to save the comment. is there another way to commit my comment?
16:10:26 tasker mriedem: I think that https://review.openstack.org/#/c/504260/2/nova/network/neutronv2/api.py@263 needs to be guarded as well, but I can't get the comment to apply on the page.
16:12:48 efried tasker What's your gerrit ID?
16:13:43 tasker efried: my launchpad ID is egrh3. is that the same thing?
16:15:06 efried tasker Was trying to find other things you've commented on in the past. Go to the front page of that change set, click the "Add Reviewer" button (little person icon to the right on the "Reviewers" line) and punch "Add Me".
16:16:15 efried tasker gotcha. So what's happening when you try to submit a comment?
16:17:02 tasker I highlight the line, press 'c', write my comment, press [save] or "ctrl+s" and the box collapses and says "draft".
16:17:08 tasker but I don't know what to do beyond that.
16:18:11 efried tasker Ah, okay. You go back to the front page of the change and hit the Reply button. Vote if you like (or not) and hit the Post button.
16:18:36 efried tasker That'll accumulate all comments you've made at once into a review note, and make them visible to others.
16:18:40 tasker ahhh
16:19:08 tasker got it!
16:19:20 efried Yup, I can see it.
16:23:06 openstackgerrit Eric Berglund proposed openstack/nova master: PowerVM Driver: config drive https://review.openstack.org/409404
16:27:41 mriedem gibi: i'm going to miss the notifications meeting today
16:27:45 mriedem so might as well cancel
16:34:05 gibi mriedem: thanks for the heads up. I will open it to see if somebody else will join or not but won't wait for long
16:34:12 openstackgerrit Elod Illes proposed openstack/nova master: Add instance.interface_attach notification https://review.openstack.org/503089
16:37:28 sdague efried: for https://review.openstack.org/505317, can you remove the if condition too (the 2 lines before it)
16:37:49 sdague basically it's been deprecated since newton to have non urls in there
16:38:06 efried sdague Was wondering about that. So we just let it fail hard in the request if they've omitted the protocol?
16:39:08 sdague yes
16:39:21 efried sdague Roger wilco.
16:39:33 sdague if they don't provide the url then the whole uwsgi thing can't work
16:42:12 openstackgerrit Eric Fried proposed openstack/nova master: Don't fix protocol-less glance api_servers anymore https://review.openstack.org/505317
16:42:17 efried sdague ^ Done.
16:43:13 sdague efried: ok, cool, last thing, I think we probably need a reno to tell people that they will hard fail if they only use IPs
16:43:40 efried sdague Okay.
16:49:56 openstackgerrit Eric Fried proposed openstack/nova master: Don't fix protocol-less glance api_servers anymore https://review.openstack.org/505317
16:49:57 efried sdague ^ Not real experienced with release notes, that okay?
16:51:39 sdague efried: wfm
16:52:13 dansmith jaypipes: you around?
16:58:50 openstackgerrit Eric Fried proposed openstack/nova-specs master: Spec: Use keystoneauth1 Adapter for endpoints https://review.openstack.org/500190
16:59:03 efried sdague ^ Added barbican. That sucker should be ready for review, I think.
16:59:17 efried mriedem FYI ^
17:31:45 cfriesen anyone know if region names are case sensitive?
17:32:13 openstackgerrit Ed Leafe proposed openstack/nova-specs master: Re-propose nested resource providers spec https://review.openstack.org/505209
17:32:45 edleafe cfriesen: I know that when I worked with RAX regions, they were
17:55:35 tasker the live-migration of the instance that was interrupted during the "post-migrtaion" tasks and the BINDING_PROFILE=None exception, the instance moved to the target host, but nova was interrupted and didn't update the database. nova thinks the instance is still on the original host. how can I get nova to update itself?
17:56:16 tasker restarting the `nova-compute` service did not do what I thought it might -- look to see what instances were active on the compute-host and update the tables accordingly.
17:58:09 tasker restarting results in "While synchronizing instance power states, found 2 instances in the database and 1 instances on the hypervisor." followed by "Instance is unexpectedly not found. Ignore."
17:58:43 tasker that's on the original host. the destination host has "While synchronizing instance power states, found 3 instances in the database and 4 instances on the hypervisor." and nothing else.
18:02:05 tasker i found https://bugs.launchpad.net/nova/+bug/1288958 on the same "Instance is unexpectedly not found. Igonre." message, but that one expired in April `16. the steps disclosed there are different but the state of Nova is similar.
18:02:10 openstack Launchpad bug 1288958 in OpenStack Compute (nova) "nova out of sync with the hypervisor " [Medium,Expired]
18:02:52 tasker nova list shows my particular instance with "power state = NOSTATE"
18:12:35 melwitt tasker: was it the 'setup_networks_on_host' that failed during post_live_migration_at_destination? because if so, that means the network failed setup on the destination and probably isn't working properly on the target
18:13:32 melwitt (I would think, I'm not a live migration expert)
18:20:11 tasker I don't see `setup_networks_on_host` in the traceback. it's "post_live_migration_at_destination -> migrate_instance_finish -> _update_port_binding_for_instance"
18:20:29 tasker do you have a pastie site that you prefer to use? I can flip you the traceback.
18:22:19 melwitt okay, I see the network_api.migrate_instance_finish call (just looking at the code). it's part of the network setup AFAICT
18:23:11 melwitt we use paste.openstack.org and pastebin.com
18:24:20 melwitt but just looking at the code, you're seeing it fail during the network setup at the destination, which would mean it's not going to work properly there, so it's not updating it to the target
18:25:57 melwitt yeah, the migrate_instance_finish is what updates the port binding for the instance (see nova/network/neutronv2/api.py)
18:27:46 melwitt if that failed, I don't think it would be correct to update the instance host to the target host. so AFAICT, the instance is still on the original host and there's a half-baked instance on the destination which needs to be cleaned up
18:28:16 tasker virsh list shows no instance on the original host.
18:28:49 tasker it does show it at the target host, but I cannot tell what state it's in.
18:28:52 melwitt *looking at more code* yeah, I was trying to see what has happened to the libvirt domain by this point
18:31:33 tasker melwitt: http://paste.openstack.org/show/621469/
18:31:38 melwitt so it moved the domain, failed to update the port binding, so it's not in a working state. so far I'm not seeing how you could recover from that
18:32:13 tasker deletion is recovery, right? <G>
18:33:45 melwitt heh
18:34:06 openstackgerrit Claudiu Belu proposed openstack/nova master: hyperv: report disk_available_least field https://review.openstack.org/504904
18:38:03 tasker this is a test cluster so no real worries.
