| 17:05:02 | stephenfin | cdent: Might be interested in ^ | |
| 17:05:34 | cdent | I get excited whenever I see the word "Cleanup" | |
| 17:08:40 | edleafe | cdent: Cleanup in aisle 5! | |
| 17:09:40 | openstackgerrit | sean mooney proposed openstack/os-vif master: adds iptools driver for ip commands https://review.openstack.org/534307 | |
| 17:10:46 | openstackgerrit | Kashyap Chamarthy proposed openstack/nova master: [WIP] libvirt: Allow to specify granular CPU feature flags https://review.openstack.org/534384 | |
| 17:10:53 | sean-k-mooney | stephenfin: ^ this should work i think. i just finished the fuctional tests and pep8 | |
| 17:16:12 | lyarwood | melwitt: any objections to a plain recheck on https://review.openstack.org/#/c/531407/ given the failure looks unrelated? http://logs.openstack.org/07/531407/3/gate/legacy-tempest-dsvm-cells/4480311/job-output.txt.gz#_2018-01-16_04_53_50_389275 | |
| 17:17:07 | melwitt | lyarwood: yeah that's fine | |
| 17:18:48 | jaypipes | stephenfin: questions for you on that VNC security doc patch... | |
| 17:18:53 | stephenfin | hit me | |
| 17:19:03 | jaypipes | stephenfin: no, I left them in th ereview :) | |
| 17:19:23 | stephenfin | Ah, gotcha :) Finishing review of efried's OVS patch, but I'll tackle after that | |
| 17:19:37 | stephenfin | By which I mean, I'll go ask danpb what he meant | |
| 17:28:00 | stephenfin | efried: This taskflow integration is pretty neat... | |
| 17:28:29 | efried | stephenfin Thanks, yeah, it's been super useful for rollbacks and batching transactions. | |
| 17:28:40 | efried | thorst gets most of the credit for that work | |
| 17:29:03 | efried | or possibly kylekh | |
| 17:31:37 | mdbooth | lyarwood: If you're still around... I'm not 100% sure of this yet but sharing anyway. | |
| 17:32:00 | lyarwood | mdbooth: still here | |
| 17:32:06 | mdbooth | If we live migrate from a host without native luks to a host with native luks | |
| 17:32:21 | stephenfin | efried: A'ight, two small questions left | |
| 17:32:26 | efried | esberglu ^ | |
| 17:32:31 | stephenfin | Other than that, it _looks_ fine. I can't test it though, obv | |
| 17:32:41 | stephenfin | Relying on the third-party CI to do that | |
| 17:32:42 | mdbooth | I think that on the destination we will not have disk/encryptor | |
| 17:32:42 | efried | stephenfin That's okay, our CI does. | |
| 17:32:43 | efried | yup | |
| 17:32:47 | stephenfin | Spot on | |
| 17:32:49 | mdbooth | But we *will* have the secret | |
| 17:32:55 | stephenfin | Just those two so and I'm good | |
| 17:33:07 | efried | stephenfin We can sell you a POWER9 system to test on. | |
| 17:33:24 | lyarwood | mdbooth: I think nova/virt/libvirt/migration.py would take care of that with the XML update | |
| 17:33:37 | mdbooth | Looking | |
| 17:33:38 | lyarwood | mdbooth: we get_volume_config on the dest and then update the volume XML with anything new | |
| 17:34:12 | lyarwood | mdbooth: I had to look into that for the native to native case | |
| 17:34:27 | lyarwood | mdbooth: didn't think of the encryptor to native case but that *should* work | |
| 17:34:33 | mdbooth | Reading... thanks. | |
| 17:38:03 | openstackgerrit | Merged openstack/nova master: conf: Do not inherit image signature props with snapshots https://review.openstack.org/527046 | |
| 17:39:26 | BKaminski | Time for my third shift self to head to sleep. If anyone who is familiar with the XenAPI drivers get a chance, would love if you could take a look at my small commit :) https://review.openstack.org/#/c/533168/ Have a great day evreyone. | |
| 17:40:28 | mdbooth | lyarwood: Time for another sanity check: I think that might not work, because get_updated_guest_xml() runs on the source, not the dest. | |
| 17:40:57 | lyarwood | mdbooth: odd, that wouldn't make sense | |
| 17:41:11 | lyarwood | mdbooth: well, to me at least :) | |
| 17:41:24 | lyarwood | mdbooth: I assumed it wanted the updated volume XML from the dest POV | |
| 17:41:24 | mdbooth | It's used to generate the destination xml to pass to the destination in initiating the migration | |
| 17:41:57 | mdbooth | It runs from _live_migration_operation, which I'm pretty sure is on the source | |
| 17:42:44 | mdbooth | But we do call _connect_volume() on the destination | |
| 17:42:58 | mdbooth | in pre_live_migration | |
| 17:44:14 | lyarwood | right but the volume secret lookup would return the src hosts secret UUID | |
| 17:44:17 | mdbooth | And use_native_luks will be true on the destination, so we'll create the host secret | |
| 17:44:45 | lyarwood | that's pretty useless, updating instance XML using the src host | |
| 17:44:57 | mdbooth | No, it's the other way round | |
| 17:45:13 | mdbooth | When we call _attach_encryptor during pre_live_migration on the destination | |
| 17:45:27 | mdbooth | We will create the host secret on the destination | |
| 17:46:15 | mdbooth | Also... we won't actually attach the encryptor | |
| 17:46:25 | lyarwood | right, but _get_volume_config is being called on the src, that does the secret lookup | |
| 17:46:39 | mdbooth | No it doesn't, because the source hasn't been upgraded | |
| 17:47:11 | lyarwood | ah right, in that old to native use case, you're correct | |
| 17:47:12 | mdbooth | I think we're uncovering a design defect in live migration here, tbh | |
| 17:47:22 | mdbooth | But it is what it is | |

| 17:47:59 | efried | mgoddard This whole thing has been rearranged and rebased ^ | |
| 17:48:20 | efried | mgoddard I noticed you put some stuff on top (or in the middle, or something) - it'll need to be rebased accordingly. | |
| 17:48:24 | mdbooth | efried: Zuul can take another one for the team ;) | |
| 17:48:49 | mdbooth | lyarwood: So I'm not 100% sure what the state would be on the destination | |
| 17:48:57 | efried | mdbooth The way zuul has been treating me lately, I don't have too much sympathy. | |
| 17:49:03 | mdbooth | efried: Hehe | |
| 17:49:08 | efried | Course, zuul is in the position of power, there. | |
| 17:49:38 | efried | jaypipes See above: snapshot comes first now, followed by set_traits_for_provider so mgoddard can use it for the ironic traits bp. | |
| 17:49:59 | mdbooth | lyarwood: Given that this would be a hopefully ephemeral situation, I wonder if we can detect this in pre_live_migration and fail early. | |
| 17:50:47 | mdbooth | lyarwood: i.e. the fix is to not allow live migration host->native encryption | |
| 17:51:00 | lyarwood | mdbooth: well, this breaks native to native as well right? | |
| 17:51:09 | mdbooth | It goes away when they finish the upgrade | |
| 17:51:14 | mdbooth | lyarwood: Does it? | |
| 17:51:14 | lyarwood | mdbooth: if we can't lookup the UUID of the new secret on the dest and udpate the XML we can't migrate | |
| 17:51:38 | lyarwood | mdbooth: we'd just end up pointing to the src secret UUID that doesn't exist on the dest | |
| 17:51:45 | mdbooth | lyarwood: I thought we were using the volume id as the secret uuid, no? | |
| 17:52:16 | lyarwood | mdbooth: no, the lookup code uses the volume_id, the actual secret has a seperate UUID you need to provide in the XML | |
| 17:52:24 | efried | oh gdi. Stupid pep8 mistakes. And on the bottom patch, of course. | |
| 17:53:00 | mdbooth | efried: LOL. FWIW: 'git rebase -i master -x "tox -e pep8 -- -HEAD"' is your friend | |
| 17:53:23 | efried | ooo | |
| 17:53:29 | mdbooth | Will run pep8 against each of your patches individually | |
| 17:53:32 | jaypipes | efried: acl | |
| 17:53:34 | efried | That's slightly easier than the way I was gonna do it. | |
| 17:53:36 | jaypipes | ack | |
