| 13:54:18 | dansmith | to discuss your discovery thing? | |
| 13:54:50 | bauzas | https://etherpad.opendev.org/p/nova-bobcat-ptg#L473 | |
| 13:55:01 | noonedeadpunk | Yep, sure | |
| 13:55:05 | noonedeadpunk | sec | |
| 14:10:30 | bauzas | sean-k-mooney: are you able to join the nova session ? | |
| 14:11:34 | bauzas | (we're on a break til 1415UTC) | |
| 14:47:22 | bauzas | break until 3pm utc | |
| 14:52:45 | bauzas | gmann: dansmith: fwiw, the gate gives me headaches back these days | |
| 14:53:14 | bauzas | I'll need to scrub all the rechecks I made and try to follow the most common patterns | |
| 14:54:00 | bauzas | things were quiet for 3 weeks, but now it becomes worst (I guess because we're back on a full dev cycle so more job runs at the same time) | |
| 14:56:24 | gmann | bauzas: are you seeing this volume state error or something else also https://12df9c834cfda7bed796-e5788b19bd89c28fd446f909c1b0ae99.ssl.cf5.rackcdn.com/875621/10/check/nova-ceph-multistore/91680b5/testr_results.html | |
| 15:30:35 | stephenfin | bauzas: Was this what you were looking for review of? https://review.opendev.org/c/openstack/python-openstackclient/+/851244 You need to rebase it if so then gtema can take a look | |
| 15:31:56 | bauzas | stephenfin: yup that's the one and yeah now I have work to do | |
| 16:25:47 | bauzas | tobias-urdin: ping again for trim supprot for virtio-blk being discussed now | |
| 16:49:05 | bauzas | aaand then attending the tc meetings while drinking a beer | |
| 16:49:29 | elodilles | sean-k-mooney: this mail talks about 3 PTG: https://lists.openstack.org/pipermail/openstack-discuss/2022-December/031512.html | |
| 16:51:17 | elodilles | bauzas: enjoy your beer! (I had a french wine but already finished it yesterday ;)) | |
| 16:51:48 | bauzas | elodilles: hah, from which valley ? :) | |
| 16:54:35 | elodilles | bauzas: to tell you the truth it wasn't a fancy wine, so it just wrote that it is from southern parts of France or something like that o:) | |
| 16:55:17 | elodilles | bauzas: so that's why you like better beer than wine :D | |
| 16:55:48 | bauzas | elodilles: I usually like both ) | |
| 16:55:50 | bauzas | :) | |
| 16:56:38 | bauzas | elodilles: but beer is more for connecting with folks, while I usually take wine for very specific cases, mostly at home | |
| 16:57:20 | bauzas | wine glasses are so expensive at restaurants and very rarely good (or they are damn $$$) | |
| 16:59:23 | elodilles | that's true, a rare, quality wine can cost a fortune :P | |
| 17:00:13 | elodilles | i'm good though with a simple but good wine (especially as I don't drink much o:)) | |
| 17:03:27 | melwitt | I like beer a lot more than wine but where I live there are craft breweries everywhere nearby | |
| 17:05:45 | sean-k-mooney | elodilles++ | |
| 17:11:15 | elodilles | melwitt: that's understandable then ;) craft breweries had a trend in the past years so we had some too in this part of europe. and some are quite OK :D | |
| 17:13:28 | melwitt | elodilles: yeah honestly I usually drink what's good in the area. when I spent time in france and italy for example, I switched largely to wine while I was there bc there was much more good wine than good beer around :) | |
| 17:15:17 | elodilles | yepp, "when in Rome..." ;) | |
| 17:15:21 | melwitt | the beer choices were basically peroni or peroni | |
| 17:19:26 | elodilles | in restaurants, i guess the situation is similar here (having 1 or 2 kinds of beer only) except in the capital or bigger cities | |
| 17:19:57 | elodilles | (and of course where there are some breweries) | |
| 17:22:16 | elodilles | but i can imagine places which are famous for their wines don't need big selection of beer, of course :D | |
| 17:23:06 | melwitt | yeah exactly. even if they had them they probably wouldn't sell much. so I get it | |
| 17:24:42 | elodilles | :] | |
| 17:25:57 | dansmith | bauzas: so, did I miss anything important from the rest of the nova stuff after I dropped? | |
| 17:27:53 | bauzas | dansmith: nope, not really | |
| 17:28:08 | dansmith | cool | |
| 17:28:11 | bauzas | most topics were merely whether those were bugs or features | |
| 17:28:15 | bauzas | but, | |
| 17:28:26 | bauzas | we had one topic about a nova-manage command spec | |
| 17:28:33 | bauzas | you may be interested in the spec reading | |
| 17:28:51 | bauzas | I had concerns about the residues it could leave on the compute | |
| 17:30:03 | dansmith | okay | |

| 06:20:48 | opendevreview | Amit Uniyal proposed openstack/nova-specs master: Add cleanup flag to remove dangling volumes https://review.opendev.org/c/openstack/nova-specs/+/878757 | |
| 07:41:51 | auniyal | Hi sean-k-mooney | |
| 07:42:15 | auniyal | ) | |
| 07:42:15 | auniyal | https://review.opendev.org/c/openstack/nova/+/877500 - (Don't provide MTU value in metadata service if DHCP is enabled | |
| 07:42:36 | auniyal | is this required in yoga as well ? | |
| 07:47:15 | bauzas | auniyal: if you read the bug report, you'll understand that it's not related to some Nova release, right ? | |
| 07:47:46 | bauzas | it's due to the fact that we pass a wrong MTU to the metadata API, so cloud-init sets it | |
| 07:48:05 | bauzas | since the operator provided another MTU value for the DHCP domain, we need to use it | |
| 09:41:41 | gibi | bauzas: I caught up on the Friday ptg etherpad. Sorry for missing the discussion in real time. | |
| 09:41:51 | bauzas | np at all | |
| 09:42:00 | bauzas | hope your wife was ok | |
| 09:42:10 | bauzas | anyway, /me needs to go off | |
| 09:42:18 | gibi | bauzas: I agree to try to discuss the limited scope lower constriants job during one of the weekly meetings | |
| 09:42:22 | bauzas | (yet again taxi needs) | |
| 12:05:29 | dvo-plv | sean-k-mooney: Hello. I have a question regarding third patry cicd from napatech | |
| 12:05:50 | sean-k-mooney | sure | |
| 12:06:46 | dvo-plv | Could we create our own napatech tempest plugin, maybe just a copy of renegade job or rebase some otehr tests, what will be required, but with a modification for our configuration stesps, create vm with virtio-forwarder or set device_spec varainle, etc? | |
| 12:07:11 | sean-k-mooney | you could but that shoudl not be required | |
| 12:07:26 | sean-k-mooney | tempest allows you to set teh vnic type to use | |
| 12:08:03 | sean-k-mooney | https://github.com/openstack/tempest/blob/master/tempest/config.py#L814-L821 | |
| 12:08:25 | sean-k-mooney | so if you set that to virtio-forwarder then it will use that when creating ports | |
| 12:09:59 | sean-k-mooney | dvo-plv: https://docs.openstack.org/neutron/latest/contributor/policies/thirdparty-ci.htmlhttps://docs.openstack.org/neutron/latest/contributor/policies/thirdparty-ci.html is neutrons requimentss for third party ci | |
| 12:10:01 | dvo-plv | I see, Could you also clarify what tests we have to execute for verification? smoke and renegade ? | |
| 12:10:21 | sean-k-mooney | im not sure what renegade is but smoke is not enough | |
| 12:10:32 | opendevreview | Merged openstack/nova stable/train: [compute] always set instance.host in post_livemigration https://review.opendev.org/c/openstack/nova/+/864055 | |
| 12:10:47 | sean-k-mooney | ideally you woudl run the networkign and compute api tests and network basic ops as a minium | |
| 12:11:55 | dvo-plv | I see, thanks | |
| 12:13:01 | dvo-plv | Do you have some time for our blueprint with packed ring https://review.opendev.org/c/openstack/nova-specs/+/868377 ? | |
| 12:15:03 | damnthem | hello. i'm having trouble figuring out why does during openstack server backup nova creates two copies of instance disk in temp folder (one, which is mirror name.delta, and second one, which is a "flat copy" of that mirror) https://opendev.org/openstack/nova/src/commit/29de62bf3b3bf5eda8986bc94babf1c94d67bd4e/nova/virt/libvirt/driver.py#L3310-L3365 There are comments in code that suggests that delta is part of backing chain b | |
| 12:16:03 | sean-k-mooney | dvo-plv: ill try and find some time to do upstream view in general tomorrow morning. im not sure ill have time to do reviews today but ill try and do a review of openspecs tomorrow | |
| 12:17:22 | sean-k-mooney | damnthem: locally the vm will execute form the delta disk but we need to upload the flat image to glance | |
| 12:17:42 | sean-k-mooney | glance images cannot be delta disk over other images | |
| 12:18:41 | sean-k-mooney | at least not for qcow/raw images | |
| 12:19:11 | dvo-plv | Thank you, have a good day | |
| 12:19:27 | sean-k-mooney | if its boot from volume or nova is using rbd then we do the snapshot directly in the storage backend and do a thin snapshot | |
| 12:19:38 | sean-k-mooney | if the storage backend supports that | |
| 12:37:41 | opendevreview | liang jiechao proposed openstack/nova-specs master: Generic vdpa spec https://review.opendev.org/c/openstack/nova-specs/+/879338 | |
| 12:47:52 | damnthem | sean-k-mooney: vm works locally from {instance}/disk isn't it? Also domxml and qemu-img info doesnt show any backing chains for mirror/delta. And dev.rebase creates full copy of image (mirror https://qemu-project.gitlab.io/qemu/interop/live-block-operations.html#live-disk-synchronization-drive-mirror-and-blockdev-mirror) https://opendev.org/openstack/nova/src/commit/29de62bf3b3bf5eda8986bc94babf1c94d67bd4e/nova/virt/libvirt/d | |
| 12:48:53 | opendevreview | liang jiechao proposed openstack/nova-specs master: Generic vdpa spec https://review.opendev.org/c/openstack/nova-specs/+/879338 | |
| 12:50:46 | sean-k-mooney | damnthem: the specific way we create snapshots is rather complicated and is done in a specic way for both legacy and technical reasons related to minimising the impact on the running guest | |
| 12:51:56 | Uggla | gibi, Hi I'm looking at https://review.opendev.org/c/openstack/nova/+/855664/ , so it needs to be backported down to train ? | |
| 12:53:59 | sean-k-mooney | damnthem: https://github.com/openstack/nova/blob/29de62bf3b3bf5eda8986bc94babf1c94d67bd4e/nova/virt/libvirt/driver.py#L3286-L3369 this is the relevent code | |
| 12:57:34 | sean-k-mooney | damnthem: https://github.com/openstack/nova/commit/46de2d1e2d0abd6fdcd4da13facaf3225c721f5e was the orgianl patch that add live-snapshots and it descibe the limitation around blockrebase and shallow copies | |
| 12:59:24 | sean-k-mooney | we later optimised this futher in https://github.com/openstack/nova/commit/caf5faf55670ab212868498e421bedc074fafd89 to reduce the time we need to freeze the fs | |
| 13:02:25 | damnthem | sean-k-mooney: Yeah i read that, and that's actually source of my confusion. Commit message says: "This process ultimately produces a CoW file, representing only the current delta between the root disk and backing file". But it's not in current state. There are 3 full copy at some point: instance disk, mirror and converted image from mirror. | |
| 13:08:48 | sean-k-mooney | i need to prepare for a meeting shortly so perhaps others can continue this converstation. without digining into the code my understanding of the process a a high level is we do somthign like this | |
| 13:09:26 | sean-k-mooney | first we create a delat disk by using the same backing as the vm image | |
| 13:10:01 | sean-k-mooney | this basically recreates teh state to the vm before it started runing for the first tiem | |
