| 16:30:34 | mriedem | jangutter: ++ | |
| 16:30:38 | jangutter | edmondsw: os-vif is for EVERYONE | |
| 16:30:39 | mriedem | i wish os-brick was passing objects to nova | |
| 16:30:55 | edmondsw | jangutter ok tx for clarifying | |
| 16:30:59 | mriedem | the host connector dict to/from os-brick and the connection_info dict to/from cinder are totally random | |
| 16:31:27 | mriedem | but standardizing connection_info across 80 cinder backends isn't anything anyone wants to work on | |
| 16:32:17 | jangutter | edmondsw: I think the first reference plugins was for OVS and linuxbridge, but the VIF migration is still underway. There's not a lot left for libvirt anymore. | |
| 16:33:04 | edmondsw | we have a TODO to try to use os-vif. I will expand my thinking to include SEA as well as OVS for that | |
| 16:33:09 | efried | edmondsw: Yeah, it looks like maybe we're supposed to provide an os_vif.objects.vif.VIFSharedEthernetAdapter whose `plugin` field points to... some version of our networking-powervm ml2 thingy?? | |
| 16:33:16 | edmondsw | I believe sean-k-mooney had said he might help look at that | |
| 16:34:07 | efried | edmondsw: Okay, if we have a TODO to work on os-vif integration, that's enough for me for now in that direction. | |
| 16:34:28 | edmondsw | yep, it's listed in https://etherpad.openstack.org/p/powervm-in-tree-todos | |
| 16:34:41 | efried | edmondsw: My immediate goal is just to understand the framework so I have context when cyborg says "os-acc is structured like os-vif" and assumes you know what that means. | |
| 16:35:03 | edmondsw | efried add any comments that in that etherpad as appropriate | |
| 16:37:06 | jangutter | edmondsw: efried: nova + external ovs-vif plugin should look and operate exactly like "legacy nova vif handling" (at this stage of os-vif migration) | |
| 16:37:55 | jangutter | edmondsw: efried: the only difference, is that at some point during the plugging process code under your control gets run. | |
| 16:38:03 | efried | jangutter: I haven't looked yet, do folks converting from legacy to os-vif keep their plugin in the same external project or create a new one just for os-vif? | |
| 16:38:42 | jangutter | efried: I think there's only a few in-tree plugins, almost everything is designed to be external or 3rd party. | |
| 16:38:57 | efried | jangutter: That's what I mean - external/3rd-party | |
| 16:39:37 | jangutter | efried: I'm not 100% sure what's the criteria for qualifying to be a 'reference' plugin... | |
| 16:39:56 | efried | jangutter: Just thinking ahead whether code we have in openstack/networking-powervm is gonna stay there, or if we create openstack/os-vif-powervm (or whatever) | |
| 16:40:25 | jangutter | efried: ah, I've seen both. It all depends on the project, I guess. | |
| 16:40:46 | efried | okay | |
| 16:41:06 | jangutter | efried: and the convention seems to be something like vif_plug_powervm (for the os-vif plugin name) | |
| 16:41:42 | efried | jangutter: We're likely to have more than one - vif_plug_sea_powervm, vif_plug_sriov_powervm | |
| 16:42:05 | efried | anyway, I don't want to try to solve that now. | |
| 16:43:16 | efried | can I just say it's confusing that a `plugin` is responsible for providing `plug` and `unplug` actions. | |
| 16:44:12 | dansmith | man, infra is pretty busy | |
| 16:44:23 | dansmith | things have been in there 1.5 hours that still haven't even started a single job | |
| 16:47:42 | openstackgerrit | Eric Berglund proposed openstack/nova master: Powervm configuration cleanup https://review.openstack.org/575171 | |

| 16:50:58 | simondodsley_ | mriedem: can we force a rerun of the final checks for https://review.openstack.org/#/c/558530/ | |
| 16:53:19 | jangutter | efried: wait till you try to to say out loud that this plugin is responsible for VIF plugging in Nova. | |
| 16:59:33 | mriedem | simondodsley_: yes, just leave a comment of "recheck" on the change | |
| 16:59:46 | mriedem | simondodsley_: note that because of the depends-on to the cinder docs patch, the nova patch won't merge until the cinder change merges | |
| 17:00:59 | dansmith | I just did | |
| 17:01:08 | dansmith | checked the failure and it seems unrelated | |
| 17:07:41 | BlackDex | Hmm i'm getting an error "DBNonExistentTable: (sqlite3.OperationalError) no such table: services" | |
| 17:11:00 | openstackgerrit | Jan Gutter proposed openstack/nova-specs master: Spec to implement vRouter HW offloads https://review.openstack.org/567148 | |
| 17:20:53 | simondodsley_ | mriedem: I did a "recheck" and nothing happened... | |
| 17:21:31 | mriedem | simondodsley_: see dansmith above about busy infra | |

| 17:32:53 | mriedem | alright people https://review.openstack.org/#/c/486204/ | |
| 17:33:01 | mriedem | melwitt: if you have the guts ^ | |
| 17:34:24 | jangutter | Just out of scary curiosity, what's the highest revision count you've ever seen for a single review? | |
| 17:36:27 | melwitt | mriedem: holy smokes, that's a lot of comments | |
| 17:40:35 | mgagne | mriedem: I tried to run the allocation healer on a cell with libvirt and it crashes with an InstanceNotFound exception. I found that this instance is deleted. So I'm wondering if the code still read deleted instance? And in which database, compute cell? | |
| 17:42:00 | mgagne | the traceback: https://gist.github.com/mgagne/7511aa1e95f624f872d988a34a1a55be | |
| 17:45:08 | dansmith | melwitt: heh, I know, 20+ comments for a +2 is sketchy :) | |
| 17:45:17 | dansmith | melwitt: when you're done, you should totally look at my heartbeating patch | |
| 17:45:21 | dansmith | it'll feel nice and light | |
| 17:45:47 | melwitt | :) | |
| 17:49:57 | melwitt | jangutter: I think that review is the highest I've seen | |
| 17:50:44 | openstackgerrit | Merged openstack/nova master: api-ref: expand on various bdm parameters https://review.openstack.org/574805 | |
| 17:52:53 | dansmith | mgagne: that's reading deleted during a lazy load | |
| 17:53:16 | dansmith | mgagne: the healer is actually reading deleted initially | |
| 17:54:04 | dansmith | I guess it might need to read deleted instances to remove stale allocations maybe/ | |
| 17:54:08 | dansmith | regardless, that path should be reading deleted during flavor load I would think | |
| 17:54:34 | dansmith | ah, it's not | |
| 17:55:23 | dansmith | and, | |
| 17:55:30 | dansmith | it should be pre-loading flavor it looks like | |
| 18:03:04 | dansmith | mgagne: any chance you have an old nova python module on the system, and are just running nova-manage from newer source? | |
| 18:04:22 | openstackgerrit | Jay Pipes proposed openstack/nova master: placement: Allocation.consumer field https://review.openstack.org/565405 | |
| 18:04:23 | openstackgerrit | Jay Pipes proposed openstack/nova master: rework allocation handler _allocations_dict() https://review.openstack.org/565407 | |
| 18:04:24 | openstackgerrit | Jay Pipes proposed openstack/nova master: Add a microversion for consumer generation support https://review.openstack.org/565604 | |
| 18:04:25 | openstackgerrit | Jay Pipes proposed openstack/nova master: Fix nits from change Id609789ef6b4a4c745550cde80dd49cabe03869a https://review.openstack.org/574324 | |
| 18:11:14 | mriedem | jangutter: the multiattach one | |
| 18:12:44 | mriedem | oh maybe not, i guess it was just really old | |
| 18:12:46 | mriedem | https://review.openstack.org/#/c/271047/ | |
| 18:13:44 | mriedem | heh would be a tie with https://review.openstack.org/#/c/408964/114 | |
| 18:14:54 | mriedem | mgagne: hmm, you're running that against queens? | |
| 18:15:39 | melwitt | bpoulos: quick (hopefully) question for you here https://review.openstack.org/#/c/486204/114/nova/compute/api.py@3137 | |
| 18:16:10 | dansmith | mriedem: so on mgagne's issue, I don't know why we're not preloading flavor, but I also think it's wrong to fail lazy-loading it, so: | |
| 18:16:12 | openstackgerrit | Dan Smith proposed openstack/nova master: Always read-deleted=yes on lazy-load https://review.openstack.org/575190 | |
| 18:16:26 | dansmith | biab | |
| 18:16:38 | mriedem | dansmith: we are pre-loading flavor | |
| 18:16:46 | mriedem | _heal_instances_in_cell | |
| 18:16:48 | mriedem | oops | |
| 18:16:52 | mriedem | instances = objects.InstanceList.get_by_filters( | |
| 18:16:52 | mriedem | ctxt, filters={}, sort_key='created_at', sort_dir='asc', | |
| 18:16:52 | mriedem | limit=max_count, expected_attrs=['flavor']) | |
| 18:18:29 | efried | jangutter: https://review.openstack.org/#/c/362766/ is coming up fast | |
| 18:20:38 | jangutter | efried: now THAT is impressive. Dating from 2016 | |
| 18:21:24 | mriedem | psh https://review.openstack.org/#/c/271047/ | |
| 18:21:29 | mriedem | has a good 7 months on that | |
| 18:23:38 | openstackgerrit | Zack Cornelius proposed openstack/nova master: Implement file backed memory for instances in libvirt https://review.openstack.org/567876 | |
| 18:24:52 | bpoulos | melwitt: I'll take a look | |
| 18:25:10 | melwitt | thanks | |
| 18:25:29 | melwitt | bpoulos: I think we figured it out but would be good to get your ack | |
| 18:26:14 | mriedem | melwitt: replied to you inline | |
| 18:28:11 | mgagne | dansmith, mriedem: ok back. there is only one version of Nova installed, Queens. | |
| 18:28:20 | jaypipes | melwitt: more pug love. https://twitter.com/jaypipes/status/1006966218157445120 | |
| 18:29:14 | mgagne | so I'm wondering why preloading isn't happening and fails with lazy-loading later. | |
| 18:29:25 | mriedem | mgagne: me too, looking now | |
| 18:30:27 | mriedem | mgagne: i think i know | |
| 18:30:31 | mgagne | it's failing with an instance from 2014. So I'm wondering is something didn't get migrated (even if it's deleted) or someone messed up the database at that time. | |
