| 20:09:46 | sean-k-mooney | it been over a year since i actully hit that error and it was on cent7.5 so the libvirt we are using in the gate in the ubuntu vms is alot different | |
| 20:10:47 | efried | sean-k-mooney: what do we do about tempest tests that need a certain minimum of e.g. libvirt or qemu? | |
| 20:11:06 | efried | Do all the CI nodes have the same (latest) version? | |
| 20:11:21 | efried | hm, I guess they probably do if they all use the same image... | |
| 20:11:22 | sean-k-mooney | it depends | |
| 20:11:45 | sean-k-mooney | in some cases we have feature flags in the tempest config | |
| 20:11:56 | sean-k-mooney | but in general tempest does not have test that care | |
| 20:12:29 | sean-k-mooney | in the nova code we have checks if feature need a newer version then our minium | |
| 20:12:35 | efried | I'm going to be getting into vTPM with encryption this cycle, which requires a very recent libvirt/qemu. I don't know yet whether I'll be adding CI for it, but was curious how that would happen if I did. | |
| 20:12:59 | efried | yeah, but that'll just cause the build to fail, right? | |
| 20:13:16 | sean-k-mooney | am its a pain but we used to use fedora with the virt preview repo for that | |
| 20:13:47 | sean-k-mooney | if that is not an option we also have a devstack plugin you could use | |
| 20:13:58 | sean-k-mooney | it will compile libvirt and qemu from source | |
| 20:14:02 | efried | eek | |
| 20:14:36 | sean-k-mooney | personally i found that beeter then random fedora virt preview package | |
| 20:14:52 | efried | I don't think I need *unreleased* versions. Just pretty recent ones. | |
| 20:14:53 | sean-k-mooney | efried: do you know what version you need | |
| 20:15:01 | efried | yeah, one sec... | |
| 20:16:10 | efried | sean-k-mooney: libvirt 5.6.0. qemu at least 1.11, but possibly higher, not sure. | |
| 20:16:14 | efried | sorry, 2.11 | |
| 20:16:43 | sean-k-mooney | ok fedroa 20 might have that 5.6 is pretty new i think | |
| 20:16:46 | sean-k-mooney | https://opendev.org/x/devstack-plugin-libvirt-qemu | |
| 20:16:54 | sean-k-mooney | i can try and build those with that too | |
| 20:17:01 | sean-k-mooney | i havent really been maintaining that | |
| 20:17:12 | sean-k-mooney | but its what we used to use at intel to test prerelease stuff | |
| 20:18:17 | mriedem | artom: -1ing your DNM changes is how i stay up on stackalytics | |
| 20:21:53 | mriedem | the bottom 2 trivial changes in the cross-cell resize series are begging for another core https://review.opendev.org/#/c/692856/ | |
| 20:22:03 | mriedem | they are, not me | |
| 20:22:56 | sean-k-mooney | efried: ill test it but i think you just need to add http://paste.openstack.org/show/785823/ for the devstack plugin | |
| 20:26:38 | openstackgerrit | Archit Modi proposed openstack/nova master: Revert "openstack server create" to "nova boot" in nova docs https://review.opendev.org/693065 | |
| 20:30:21 | efried | whoah, I appear to have 4.0.0 on my bionic | |
| 20:30:32 | efried | is the apt package level the number I want to be looking at? | |
| 20:30:50 | sean-k-mooney | 4.0 of? | |
| 20:31:02 | sean-k-mooney | libvirt you check with libvirtd --version | |
| 20:31:23 | efried | yeah, 4.0.0 | |
| 20:31:51 | sean-k-mooney | ya and ubuntu 18.04 has 2.11 libvirt | |
| 20:32:00 | sean-k-mooney | *qemu | |
| 20:32:29 | sean-k-mooney | so the qemu in the gate should be fine | |
| 20:32:35 | efried | confirmed 2.11 | |
| 20:33:04 | efried | Is there a way *other* than building from source (which I have chronically shit luck with, no matter what I'm trying to build) to get a higher libvirt on my bionic? | |
| 20:33:39 | sean-k-mooney | i dont think there is a ppa but it migth be in the ubuntu cloud archive | |
| 20:33:43 | sean-k-mooney | let me check | |
| 20:34:39 | sean-k-mooney | ya they have 5.4 | |
| 20:34:47 | sean-k-mooney | http://ubuntu-cloud.archive.canonical.com/ubuntu/pool/main/libv/libvirt/ | |
| 20:35:04 | sean-k-mooney | you need 5.6 however right | |
| 20:35:05 | efried | okay, so if I need 5.6.0 I need to build | |
| 20:35:06 | efried | yeah. | |
| 20:35:15 | efried | wah wah wahhhhh | |
| 20:36:46 | sean-k-mooney | even the libvirt ppa is 5.4 https://launchpad.net/ubuntu/+source/libvirt | |
| 20:37:20 | sean-k-mooney | ill let you know in a few minute i the plug still work. | |
| 20:37:57 | efried | sean-k-mooney: I gotta do this locally first anyway | |
| 20:37:58 | sean-k-mooney | i havenet used it in like 2 years but i wrote the first version of it to solve this exact problem | |
| 20:38:19 | efried | unless you're saying I can use the plugin to do it locally.... which would make a certain amount of sense ;P | |
| 20:38:30 | sean-k-mooney | yes you can | |
| 20:38:54 | sean-k-mooney | its just a devstack plugin so you can run it locally by adding the 3 lines i sent you to your local.conf | |
| 20:39:55 | sean-k-mooney | it should intall all the deps to build it and checkout the version you set as part of stacking | |
| 20:40:42 | efried | oo | |
| 20:44:19 | efried | mriedem: done | |
| 20:46:53 | efried | sean-k-mooney: trying.... | |
| 20:47:02 | mriedem | efried: thanks | |
| 20:47:32 | sean-k-mooney | efried: libvirt just finsihed building for me | |
| 20:47:33 | efried | I couldn't just sit here listening to all the begging. | |
| 20:47:38 | sean-k-mooney | its working on qemu now | |
| 20:47:54 | efried | sean-k-mooney: cool, so given that I'm running 1/128th of the cores you are, mine will finish some time tomorrow? | |
| 20:48:31 | sean-k-mooney | its not that bad. im limited by disk io | |
| 20:49:00 | sean-k-mooney | it will add maybe 5-10 mins on the build at most and i setup the pluging to cache the build | |
| 20:49:34 | sean-k-mooney | it creates a BUILD_COMPLETE file in /opt/stack/libvirt and /opt/stack/qemu | |
| 20:49:48 | sean-k-mooney | so you dont need to do it again unless you want too | |
| 20:50:05 | sean-k-mooney | unstack does not delete that file but clean will | |
| 20:50:34 | efried | nice | |
| 20:50:44 | efried | By sheer luck, I totally asked the right person. | |
| 20:51:03 | efried | ...unless it doesn't work for me. In which case you're fired. | |
| 20:51:15 | sean-k-mooney | assuming it still works you can also give it a set of patchwork urls and to test with unmerged patche to both too | |
| 20:51:34 | efried | hum, I seem to still be running under py2, which probably isn't my best call. | |
| 20:51:52 | sean-k-mooney | it will proably be fine | |
| 20:51:56 | efried | Do I just fix that by setting USE_PYTHON3=true in my local.conf? | |
| 20:52:01 | sean-k-mooney | for about another week or two | |
| 20:52:08 | sean-k-mooney | yes | |
| 20:52:23 | efried | well, I don't really care except that I'm trying to be close to realistic here. | |
| 20:52:46 | sean-k-mooney | if your talking to a bank they will be running python 2 for the next decade | |
| 20:53:24 | sean-k-mooney | setting USE_PYTHON3=true wont remove the py2 stuff so its best to do that on a clean vm | |
| 20:53:41 | efried | would you be disgusted if I told you I'm not running in a VM? | |
| 20:53:44 | rouk | s/python 2/COBOL or some variant of BASIC or java 1.0/g | |
| 20:54:33 | sean-k-mooney | efried: not really if you have a dev server | |
| 20:54:42 | sean-k-mooney | i would not run devstack on my laptop directly however | |
| 20:54:42 | efried | indeed rouk. FORTRAN etc. Course, they're probably not running OpenStack in those languages. | |
| 20:54:50 | efried | yeah, I've got some dev NUCs. | |
| 20:55:25 | efried | I think it's building libvirt... | |
| 20:56:36 | sean-k-mooney | just finished qemu | |
| 20:57:43 | sean-k-mooney | ... and it failed... sudo addgroup -f -r libvirt | |
| 20:57:45 | sean-k-mooney | Option f is ambiguous (firstuid, force-badname) | |
| 20:57:47 | sean-k-mooney | Unknown option: r | |
| 20:57:55 | sean-k-mooney | why do pepole change things like addgroup | |
| 21:00:00 | sean-k-mooney | oh those are the optiongs for groupadd | |
| 21:01:33 | sean-k-mooney | efried: if you have a different terminal just run "sudo groupadd -f -r libvirt" | |
| 21:02:06 | sean-k-mooney | and it will continue instaed failing or you can leave it fail and run it after and then just stack and unstack | |
| 21:04:04 | efried | thanks sean-k-mooney. Why is it ambiguous in flight and not when I run it?? | |
| 21:04:45 | sean-k-mooney | its trying to use addgroup not groupadd | |
| 21:05:26 | sean-k-mooney | https://opendev.org/x/devstack-plugin-libvirt-qemu/src/branch/master/devstack/libs/libvirt#L157 | |
| 21:05:40 | sean-k-mooney | its a bug but this has not been tested on 18.04 before | |
