| 13:42:36 | cdent | alex_xu: I borrowed that get schema from nova's positive_integer in parameter_types, which has the same redundancies (presumably to protect against the query string parsing library changing from underneath it) | |
| 14:07:01 | alex_xu | cdent: the positive_integer is used for the request body, not just the query string | |
| 14:07:44 | efried | jaypipes: I was planning to answer mriedem's call for more details on nrp (http://lists.openstack.org/pipermail/openstack-dev/2018-January/125953.html). Unless you were already doing that? | |
| 14:08:00 | jaypipes | efried: no. please go ahead. | |
| 14:08:26 | jaypipes | efried: in the middle of trying to get the aggregate affinity series straightened up. should take me another few hours. | |
| 14:09:02 | efried | jaypipes: Roger. FYI, the main thing I'd be throwing you under the bus for is accomodating nrps in GET /allocation_candidates | |
| 14:09:21 | efried | (throwing under bus - was that the right analogy? mebbe not) | |
| 14:10:04 | jaypipes | efried: that's cool. | |

| 14:55:08 | openstackgerrit | Matthew Booth proposed openstack/nova master: Fix fake libvirt XML generation for disks https://review.openstack.org/531165 | |
| 14:58:05 | mriedem | kashyap: lyarwood: thanks for looking at https://review.openstack.org/#/c/267587/ - i think we're on the same page, | |
| 14:58:15 | mriedem | libvirt 3.10 has a fix for a regression introduced in qemu 2.10 | |
| 14:58:22 | kashyap | mriedem: I noticed your ping too last evening | |
| 14:58:32 | kashyap | I saw your sleuthing on the review | |
| 14:58:36 | mriedem | so i added the version check on startup such that multiattach isn't supported unless qemu<2.10 or libvirt>=3.10 | |
| 14:58:37 | kashyap | Yep | |
| 14:58:45 | mriedem | which sucks because we don't have those versions in our CI env | |
| 14:59:39 | kashyap | (Maybe we should finally get that utopic gate job that will run on newer versions to allow us to test at least) | |
| 14:59:56 | mriedem | we are using the pike UCA which is about as new as it gets for ubuntu | |
| 15:00:30 | mriedem | jamespage: coreycb: what do you think are the chances of getting these libvirt patches backported from 3.10 to 3.6 in the pike UCA? https://bugzilla.redhat.com/show_bug.cgi?id=1378242#c10 | |
| 15:00:31 | openstack | bugzilla.redhat.com bug 1378242 in libvirt "QEMU image file locking (libvirt)" [Unspecified,On_qa] - Assigned to pkrempa | |
| 15:00:56 | kashyap | Yep, I recall; mriedem -- I wonder if you've ever seen this (for DevStack, though) -- https://review.openstack.org/#/c/108714/10 | |
| 15:01:05 | mriedem | alternatively, i'm going to have to probably look at using a special job which doesn't use the pike UCA so we just use the xenial package versions which would have qemu<2.10 | |
| 15:01:41 | mriedem | kashyap: so i thought markus_z and tonyb already had a job that does something like this | |
| 15:02:00 | kashyap | mriedem: I vaguely recall talking to them too, at Barcelona, but it didn't go anywhere | |
| 15:02:17 | mriedem | i have the job name handy, sec | |
| 15:02:28 | openstackgerrit | Matt Riedemann proposed openstack/nova stable/newton: Raise MarkerNotFound if BuildRequestList.get_by_filters doesn't find marker https://review.openstack.org/530982 | |
| 15:03:38 | kashyap | http://lists.openstack.org/pipermail/openstack-dev/2016-October/105552.html | |
| 15:03:50 | mriedem | kashyap: legacy-tempest-dsvm-nova-libvirt-kvm-apr | |
| 15:04:10 | kashyap | Thanks; let me look up the job definition | |
| 15:04:30 | mriedem | http://git.openstack.org/cgit/openstack-infra/openstack-zuul-jobs/tree/playbooks/legacy/tempest-dsvm-nova-libvirt-kvm-apr/run.yaml#n2 | |
| 15:04:50 | kashyap | Heh, you're faster than Google | |
| 15:04:57 | mriedem | codesearch.openstack.org | |
| 15:04:58 | jamespage | mriedem: looking | |
| 15:05:23 | kashyap | Oh, didn't know of that thing | |
| 15:05:50 | kashyap | Why is it called 'legacy'? | |
| 15:06:01 | mriedem | because it existed before zuulv3 | |
| 15:06:07 | coreycb | jamespage: mriedem: do those patches enable sharable disks with qemu 2.10? 2.10 is what we have for pike/queens atm. | |
| 15:06:15 | mriedem | coreycb: yes | |
| 15:06:27 | mriedem | coreycb: and yeah, qemu 2.10 is precisely the problem | |
| 15:06:40 | kashyap | Okido, makes sense. | |
| 15:07:02 | mriedem | kashyap: i don't know if that apr job works, but i can propose that we run it on devstack experimental queue so i can see | |
| 15:07:28 | kashyap | mriedem: Yeah, I'm first looking at what's in there - git://git.openstack.org/openstack/devstack-plugin-additional-pkg-repos | |
| 15:08:55 | kashyap | Last updated 01-Apr-2016. | |
| 15:09:08 | kashyap | So at least it needs updates to the file: devstack/lib/libvirt | |
| 15:09:36 | kashyap | (To reflect correct versions.) | |
| 15:10:04 | hrw | uf. one patch, one bug. and then 3 other bugs for the same. ouch | |
| 15:10:25 | kashyap | hrw: What are the three other bugs? It's the same one we were talking about earlier, right | |
| 15:10:46 | mriedem | kashyap: oh hmm https://git.openstack.org/cgit/openstack/devstack-plugin-additional-pkg-repos/tree/devstack/lib/libvirt#n21 | |
| 15:10:50 | kashyap | hrw: I'm even surprised that OpenStack even works on AArch64 | |
| 15:10:54 | mriedem | pointing at liberty still yeah... | |
| 15:11:12 | kashyap | Yeah, the last Git commit should gave it away | |
| 15:11:26 | mriedem | kashyap: and i guess these versions for libvirt and qemu https://git.openstack.org/cgit/openstack/devstack-plugin-additional-pkg-repos/tree/devstack/lib/libvirt#n24 | |
| 15:11:45 | hrw | kashyap: https://bugs.launchpad.net/nova/+bug/1741230 was opened by me for my patch. Then found https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/1673467 with some extra info. Then reported bug at upstream libvirt: https://bugzilla.redhat.com/show_bug.cgi?id=1531076 and got pointed to discussion in https://bugzilla.redhat.com/show_bug.cgi?id=1430987 one where again good info is provided. | |
| 15:11:47 | openstack | Launchpad bug 1741230 in OpenStack Compute (nova) "libvirt: use 'host-passthrough' as default on AArch64" [Undecided,In progress] - Assigned to Marcin Juszkiewicz (hrw) | |
| 15:11:48 | openstack | Launchpad bug 1673467 in OpenStack nova-compute charm "[ocata] unsupported configuration: CPU mode 'host-model' for aarch64 kvm domain on aarch64 host is not supported by hypervisor" [High,Fix released] - Assigned to James Page (james-page) | |

| 15:11:50 | openstack | bugzilla.redhat.com bug 1430987 in libvirt "No cpu model and feature in capabilities" [High,Assigned] - Assigned to abologna | |
| 15:11:59 | hrw | kashyap: we use OpenStack on AArch64 since Liberty ;D | |
| 15:12:16 | kashyap | hrw: Yeah, at this point, your getting traction on the upstream Bugzilla filed is the best bet. | |
| 15:12:48 | mriedem | looking at https://packages.ubuntu.com/search?suite=all§ion=all&arch=any&keywords=libvirt-bin&searchon=names | |
| 15:12:52 | hrw | kashyap: first edition of Linaro Developer Cloud was Liberty based. and then ~200 users/projects/companies used it. | |
| 15:12:53 | mriedem | ubuntu doesn't have a libvirt 3.10 yet | |
| 15:13:04 | kashyap | Even the UCA? | |
| 15:13:17 | hrw | kashyap: when Mitaka got released we migrated as it gave us UEFI support which simplified booting A LOT. | |
| 15:13:22 | mriedem | i assume Pike UCA is the latest, and that has libvirt 3.6 | |
| 15:13:26 | mriedem | same as bionic | |
| 15:13:34 | hrw | kashyap: then we migrated to Newton. | |
| 15:13:51 | hrw | kashyap: there are some testing deployments of Pike but we target Queens | |
| 15:13:54 | mriedem | same issue for qemu https://packages.ubuntu.com/search?suite=all§ion=all&arch=any&keywords=qemu-kvm&searchon=names | |
| 15:13:58 | mriedem | 2.10 is the latest in bionic | |
| 15:13:59 | hrw | mriedem: there is Queens UCA | |
| 15:13:59 | mriedem | and pike UCA | |
| 15:14:03 | mriedem | hrw: orly | |
| 15:14:15 | hrw | iirc | |
| 15:14:24 | hrw | http://ubuntu-cloud.archive.canonical.com/ubuntu/dists/xenial-updates/queens/ | |
| 15:14:57 | hrw | mriedem: but still libvirt 3.6.0 ;( | |
| 15:15:00 | kashyap | hrw: Okay. But meanwhile, my Aarch64 Mustang is remote, and I haven't accessed it in a while. If you get sometime, can you power your machine on (the one you talked about earlier in the day) & try? | |
| 15:15:23 | hrw | kashyap: I use xgene1 based HPe Moonshots | |
| 15:15:42 | hrw | kashyap: remotely as we have a bunch of those at Linaro lab | |
| 15:15:45 | mriedem | yup still 3.6 http://ubuntu-cloud.archive.canonical.com/ubuntu/dists/xenial-updates/queens/main/binary-amd64/Packages | |
| 15:15:49 | mriedem | so that doesn't help | |
| 15:16:07 | hrw | mriedem: make a PPA and grab libvirt from buster? | |
| 15:16:20 | kashyap | hrw: Are there any real users using OpenStack on AArch64, besides test / devel at Linaro? | |
| 15:16:29 | hrw | mriedem: that's what I did for Debian stable at Linaro | |
| 15:16:35 | hrw | kashyap: yes, they are | |
| 15:16:53 | hrw | kashyap: can not list names | |
| 15:17:11 | openstackgerrit | Eric Berglund proposed openstack/nova master: WIP: PowerVM Driver: vSCSI https://review.openstack.org/526094 | |
| 15:17:13 | kashyap | No prob | |
| 15:17:13 | hrw | kashyap: we provide VM instances as build slaves for several CI systems for example | |
| 15:17:46 | hrw | kashyap: also provided set of VMs as porter boxes for several projects | |
| 15:17:47 | kashyap | Nod | |
| 15:17:50 | mriedem | alternatively, i can push a devstack DNM patch which doesn't use the Pike UCA and we'll get qemu 2.5 | |
| 15:18:06 | kashyap | mriedem: You mean, just to exercise the relevant code for tests? | |
| 15:18:18 | mriedem | yes | |
| 15:18:56 | mriedem | even if jamespage / coreycb were able to backport those patches from 3.10 to 3.6 in the pike UCA, we'd have to put a workaround option in nova to bypass the version check and just run the multiattach code | |
