| 19:55:47 | mriedem | i know a new commit will do it | |
| 19:55:49 | mriedem | heh | |
| 19:55:57 | mikal | I have a cold, hold me | |
| 19:56:05 | mriedem | gdi mikal | |
| 19:56:11 | mriedem | you've stepped into the wrong room at the wrong time | |
| 19:56:17 | mriedem | way out of line donny | |
| 19:56:36 | jaypipes | you're outta your element, mikal | |
| 19:56:53 | mikal | jaypipes: that's always been true though | |
| 19:56:57 | jaypipes | :P | |
| 19:57:03 | mriedem | mikal, btw, given your plentiful rackspaceness, do you know if rax ever used this thing http://lists.openstack.org/pipermail/openstack-operators/2017-September/014267.html ? | |
| 19:57:05 | mikal | mriedem: my name isn't donny? | |
| 19:57:10 | mriedem | gdi mikal | |
| 19:57:23 | mriedem | https://www.youtube.com/watch?v=AS8X2Qp_6aA | |
| 19:57:48 | mriedem | i'm walter in this scenario | |
| 19:57:50 | mriedem | filled with rage | |
| 19:57:58 | mikal | mriedem: so, Rackspace is definitely running code newer than kilo, so if they haven't noticed they don't need it? | |
| 19:58:22 | mikal | mriedem: private cloud didn't use it, public might but johnthetubaguy would know more about that | |
| 19:58:36 | mikal | mriedem: ahhh, ok, I shall study before next time | |
| 19:58:50 | mriedem | mikal: anyone that was relying on it and has newer than kilo, and didn't notice, then yeah i guess we don't need it | |
| 19:59:04 | mriedem | that's the assertion in the ML thread and commit to remove it anyway | |
| 20:03:35 | melwitt | does anything ever set 'group_members' in filter_properties? I'm not finding anything https://github.com/openstack/nova/blob/master/nova/objects/request_spec.py#L205 | |
| 20:04:42 | sdague | mikal: I retool your ploop patch with the fixes from the virtuozo folks | |
| 20:04:59 | melwitt | this line is making reschedule fail with "'NoneType' object is not iterable" after a late-affinity-check failure. I don't see how reschedule after late check ever could work | |
| 20:08:23 | mriedem | melwitt: it could be a case of group_members being set on the request spec initially, and then it's transformed into the primitive filter_properties stuff which doesn't include the group_members? | |
| 20:08:32 | mriedem | i've seen some wonky stuff with how the request spec transforms to/from the legacy filter props | |
| 20:09:19 | mikal | sdague: ta, looking at it now | |
| 20:09:37 | mriedem | melwitt: see _to_legacy_group_info ? | |
| 20:09:49 | mriedem | it sets group_updated=True but doesn't include group_members | |
| 20:09:51 | melwitt | mriedem: I don't see that RequestSpec has any group_members in it. I grepped for "group_members" in nova and found nothing that ever sets it | |
| 20:10:19 | melwitt | yeah, I see that. that's the only thing that looks like it could be related | |
| 20:10:21 | mikal | sdague: looks like there is a rebase error there though? The console pty stuff is now in that patch. | |
| 20:10:43 | mtreinish | dansmith: http://logs.openstack.org/57/507657/1/check/gate-nova-python27-ubuntu-xenial/55aebe1/console.html#_2017-09-26_19_42_08_172719 | |
| 20:10:50 | mikal | sdague: I shall rectify | |
| 20:10:50 | melwitt | mriedem: late affinity check reschedule just looks totally broken unless I'm blind. which may very well be the case | |
| 20:11:00 | mriedem | melwitt: this added it https://review.openstack.org/#/c/148277/ | |
| 20:11:43 | melwitt | thanks | |
| 20:12:08 | mriedem | https://review.openstack.org/#/c/148277/64/nova/scheduler/utils.py@349 | |
| 20:12:14 | melwitt | looks like that line in scheduler/utils that sets it is gone now | |
| 20:12:36 | openstackgerrit | Ed Leafe proposed openstack/nova master: Add alternate hosts https://review.openstack.org/486215 | |
| 20:12:36 | openstackgerrit | Ed Leafe proposed openstack/nova master: Add Selection objects https://review.openstack.org/499239 | |
| 20:12:37 | openstackgerrit | Ed Leafe proposed openstack/nova master: Return Selection objects from the scheduler driver https://review.openstack.org/495854 | |
| 20:13:06 | melwitt | trying to find what removed it | |
| 20:13:08 | mriedem | melwitt: https://review.openstack.org/#/c/469037/ | |
| 20:13:22 | mriedem | pike ^ | |
| 20:13:46 | mriedem | https://review.openstack.org/#/c/469037/6/nova/scheduler/utils.py | |
| 20:13:48 | melwitt | thanks | |
| 20:14:50 | melwitt | okay, so the conductor logic is still relying on stuff being in filter_properties via RequestSpec.from_primitives | |
| 20:15:39 | mriedem | looks like it, left some comments in https://review.openstack.org/#/c/469037/6/nova/objects/request_spec.py | |
| 20:15:46 | mriedem | likely need a functional regression test to show the failure | |
| 20:15:54 | mriedem | then fix on top and backport both to pike | |
| 20:16:02 | mriedem | melwitt: do you have a bug for this? | |
| 20:17:42 | melwitt | mriedem: no, I can open one. wanted to sanity check with yall first | |
| 20:17:56 | mriedem | someone was saying they hit this exact same thing this morning to bauzas | |
| 20:18:45 | melwitt | hah, what a coinky dink | |
| 20:19:09 | mriedem | please keep that sailor talk for at home | |
| 20:20:17 | melwitt | aye aye sir! | |
| 20:20:26 | melwitt | matey | |
| 20:20:38 | melwitt | oh, that's pirate. nvm | |

| 20:22:10 | melwitt | bird bird bird bababir bird's the word | |

| 20:32:00 | efried | mriedem sdague https://review.openstack.org/#/c/488137/ should be ready again | |
| 20:32:49 | melwitt | heh | |
| 21:07:39 | openstackgerrit | Matt Riedemann proposed openstack/nova master: Add recreate test for live migrate rollback not cleaning up dest allocs https://review.openstack.org/507677 | |
| 21:07:50 | mriedem | dansmith: ^ thus begins another round of these | |
| 21:11:50 | openstackgerrit | Eric Berglund proposed openstack/nova master: PowerVM Driver: config drive https://review.openstack.org/409404 | |
| 21:36:24 | pino | Hi Folks, I'm just getting started on a project that would provide an alternative to using key-pairs for instances: ssh certificates. This requires injecting into the instance (before startup) a host certificate, a user CA public key, and authorized principals file(s); then modifying sshd_config to use them. What's the right way to hook into the co | |
| 21:36:25 | pino | mpute instance lifecycle? | |
| 21:37:40 | pino | I'm just experimenting, but I'm wondering if this would be best built as part of Nova itself, or separately hook into the lifecycle. | |
| 21:38:34 | jaypipes | pino: definitely not part of Nova itself, no. apart from writing files to a config drive, Nova doesn't mess with the VM. | |
| 21:39:14 | openstackgerrit | Matt Riedemann proposed openstack/nova master: Remove dest node allocations during live migration rollback https://review.openstack.org/507687 | |
| 21:39:47 | pino | jaypipes: ok, fair enough... but shouldn't support for ssh certificates be modelled similar to keypair support? | |
| 21:41:31 | jaypipes | pino: honestly, I'm not sure what the diff is between a key pair, with the private part of the pair downloaded to the user and the public part laid down on the VM config drive, and the SSH certificates thing you're describing. | |
| 21:41:44 | pino | And in terms of doing it outside of Nova, do you agree Nova notifications are not the right mechanism? The injection of various files, plus modification of the sshd_config must be done before first boot. Any advice about where, and how to do the hook? | |
| 21:41:47 | jaypipes | pino: I'm not an expert in ssh stuff, apologies. | |
| 21:43:00 | pino | jaypipes: I probably gave too much detail. I'm just looking for some hints about how I can hook into the startup workflow and block it until I've configured the VMs SSH the way I want it. | |
| 21:44:13 | jaypipes | pino: I think cloud-init is more what you are looking for? | |
| 21:45:22 | mriedem | pino: https://docs.openstack.org/nova/latest/user/vendordata.html | |
| 21:45:45 | mriedem | setup an external rest service that provides metadata to the guest when it's created | |
| 21:46:24 | mriedem | example https://github.com/openstack/novajoin | |
| 21:47:14 | penick | pino: I use SSH CA in my environment, maybe I can help? | |
| 21:47:21 | pino | mriedem: I saw that but wasn't sure it was the right approach. I'll take a closer look, thanks for the example. | |
| 21:48:02 | penick | I think I see what you're trying to do, and I think what you're probably going to want is to build a small webservice to create and sign SSH certificates, then tie that in with the nova vendordata stuff to get injected into the instance on boot | |
| 21:48:19 | mriedem | it's a wild penick | |
| 21:48:25 | mriedem | i wonder what the keyword is here | |
| 21:48:29 | penick | I identify as feral | |
| 21:48:47 | pino | jaypipes: I'm looking at cloud-init too... but I want my setup script to run without the user's help (they shouldn't have to do any setup). | |
| 21:49:11 | pino | penick: that makes perfect sense. | |
| 21:50:20 | pino | Ok, so I have a few topics/approaches to study. Thanks! | |
| 21:51:40 | penick | np :) | |
