| 13:00:08 | sean-k-mooney | instead of pulling the entire domain. and parsing out all the devics to try and find the specific one | |
| 13:02:16 | kashyap | Yeah, I know these (the config.py stuff) are all libvirt guest-config classes. | |
| 13:02:35 | kashyap | Maybe you want to summarize / copy paste your comment from here on the change for the record. | |
| 13:03:11 | sean-k-mooney | not really :) i could but since they have abandoned it i feel like they are nto going to work on it any more | |
| 13:03:20 | sean-k-mooney | so i wanted to see if one of use wanted to pick it up | |
| 13:03:39 | sean-k-mooney | kashyap: im expectign bauzas mtty patches to repodcue this | |
| 13:03:55 | sean-k-mooney | so as part of using mtty to test in the gate we will likely need to fix this anyway | |
| 13:03:56 | kashyap | You think so? | |
| 13:04:01 | kashyap | Got a link? | |
| 13:04:48 | sean-k-mooney | so if this is failing the way they reported it woudl cause volume detach to fail if libvirt report mdevs | |
| 13:05:03 | sean-k-mooney | so i woudl expect the volume tempest test to be failin on https://review.opendev.org/q/topic:%22mtty_support%22 | |
| 13:06:26 | sean-k-mooney | the fact it does not makes me want the repodcures even more | |
| 13:06:48 | sean-k-mooney | oh... | |
| 13:07:06 | sean-k-mooney | ok so i wonder if this only failes if you have both a vgpu and a cinder volume | |
| 13:07:11 | kashyap | Hmm | |
| 13:07:12 | sean-k-mooney | on the same vm | |
| 13:08:22 | sean-k-mooney | we dont have result anymore but it did actully fail | |
| 13:08:24 | sean-k-mooney | https://zuul.opendev.org/t/openstack/build/42a251fe1d174a2abef7016b96fe0dc4 | |
| 13:10:46 | kashyap | Ohh, so the vGPU + Cinder volume is the combo | |
| 13:14:28 | opendevreview | Merged openstack/nova stable/2024.1: Remove AMI snapshot format special case https://review.opendev.org/c/openstack/nova/+/924982 | |
| 13:21:43 | sean-k-mooney | kashyap: i think so but again they didnt provide a clear repoducer in the bug so its hard to tell exactly | |
| 13:21:50 | sean-k-mooney | but i think that has to be the case looking at the code | |
| 13:22:09 | sean-k-mooney | we are looping over the devices in the guest domain and the error is in the mdev class | |
| 13:22:21 | sean-k-mooney | so it must only be an issue when comibining both features | |
| 13:22:34 | sean-k-mooney | which would expliain why we dont see this today | |
| 13:30:59 | dansmith | sean-k-mooney: gibi: I thought we were into "written by a core, backported by a core, can be single-vote-landed by a core" on stable now | |
| 13:31:44 | sean-k-mooney | dansmith: i guess, it does not come up often | |
| 13:32:12 | sean-k-mooney | but in either case i was going to proxy your/my +2 by end of day if noone else said go for it | |
| 13:34:22 | dansmith | ack | |

| 13:57:06 | opendevreview | Rajesh Tailor proposed openstack/nova master: Handle InstanceExists exception for duplicate instance https://review.opendev.org/c/openstack/nova/+/860938 | |
| 14:00:39 | elodilles | sean-k-mooney: i'm OK to propose stable releases anytime & i don't have any important backport on my radar | |
| 14:04:37 | sean-k-mooney | elodilles: bauzas asked me to include https://review.opendev.org/c/openstack/nova/+/924514 and its backports | |
| 14:05:06 | sean-k-mooney | i think we can include https://review.opendev.org/c/openstack/nova/+/923689 also on 2024.1 | |
| 14:06:03 | elodilles | ACK, I'll wait for them then o/ | |
| 14:06:10 | bauzas | cool | |
| 14:07:45 | sean-k-mooney | elodilles: i have not realy looked at the older branch contet much | |
| 14:07:58 | sean-k-mooney | i do see some nice to haves so i may do some stable review today | |
| 14:08:17 | sean-k-mooney | but i dont see anythign super urgent | |
| 14:09:08 | elodilles | ACK, i'll check them too | |
| 14:34:37 | bauzas | sean-k-mooney: can you summarize the mdev issue you said ? | |
| 14:34:51 | bauzas | -ETOOMUCHCONTENTTODIGEST | |
| 14:35:35 | bauzas | fwiw, I need to resume my mtty series now that devstack supports 24.04 | |
| 14:36:58 | sean-k-mooney | bauzas: it appears that if a gues has an mdev and a cinder volume we cant detach t he cinder volume because the get_device_by_alis code cant hanel the fact that we dont have an aias field in the class that modeles the mdev device in the guest xml | |
| 14:37:10 | sean-k-mooney | i.e. you cant detach a cinder volume for a guest with a vgpu | |
| 14:37:34 | sean-k-mooney | we can fix that in the way propsoed in the patch but it missed the underly ing bug and did not include a repoducer | |
| 14:37:53 | bauzas | i see | |
| 14:38:06 | sean-k-mooney | the underlying bug is the get_device_by_alias code assumes all geust devices have an alias filed | |
| 14:38:18 | bauzas | so people need to rebuild the instance with a flavor without VGPU first before detaching | |
| 14:38:19 | sean-k-mooney | so we shoudl fix that | |
| 14:38:29 | bauzas | agreed | |
| 14:38:47 | bauzas | is this https://review.opendev.org/c/openstack/nova/+/925037 ? | |
| 14:38:49 | sean-k-mooney | bauzas: they might just need to stop the instnace | |
| 14:39:01 | sean-k-mooney | yep | |
| 14:39:13 | sean-k-mooney | that patch will work but it does not have enouch test coverage | |
| 14:39:30 | sean-k-mooney | and as i said the bug is reallly here https://github.com/openstack/nova/blob/7a7427691e0bd4818bb7a2c5f5371e0244addbbb/nova/virt/libvirt/guest.py#L419 | |
| 14:40:03 | bauzas | the real problem is that we didn't had any functest for that | |
| 14:40:06 | sean-k-mooney | that if assumes all devices in get_all_devices will have an alias field | |
| 14:40:19 | bauzas | because mdev support predates alias | |
| 14:40:24 | sean-k-mooney | yep | |
| 14:40:33 | sean-k-mooney | so ideally we woudl create a fucntional repoducer | |
| 14:40:35 | bauzas | but when we merged aliases series, we created a regression | |
| 14:40:48 | bauzas | yup | |
| 14:40:52 | bauzas | we need a functtest | |
| 14:41:01 | sean-k-mooney | and then fix both the underlying bug and optionall add supprot ofr alias ot mdevs even if not used today | |
| 14:41:22 | sean-k-mooney | we can fix the actual bug in 1 of 2 ways | |
| 14:41:34 | sean-k-mooney | either check if dev has an alais field before usign it | |
| 14:42:02 | sean-k-mooney | or make sure that all device will have that eihter by extending the base class or checking all child class have it | |
| 14:43:10 | sean-k-mooney | so either add it here https://github.com/openstack/nova/blob/7a7427691e0bd4818bb7a2c5f5371e0244addbbb/nova/virt/libvirt/config.py#L56 or add a hasattr check | |
| 14:46:12 | bauzas | I'm fine with the first option | |
| 14:46:42 | bauzas | the second option is better in case of *another* regression | |
| 14:46:54 | bauzas | want me to help with the reproducer ? | |
| 14:47:20 | bauzas | I just have 3.5 days to work before my PTO and I really want my mtty series to be reviewable before I leavred | |

| 16:20:49 | sean-k-mooney | bauzas: i rehcecked the last patch in your mtty seriese and it didnt repoduce the cinder issue but it did fail with https://paste.opendev.org/show/bexn6H6KYRrAlhNONtVn/ | |
| 16:22:49 | sean-k-mooney | there is a bug somewehre but im not sure that https://review.opendev.org/c/openstack/nova/+/918420/ is even current | |

| 17:25:47 | sean-k-mooney | bauzas: if you have time to work on it do | |
| 17:26:21 | sean-k-mooney | perhaps just try that usecase "mdev + cinder volume in the same vm" when working on the mtty stuff | |
| 17:26:27 | sean-k-mooney | and see if you see the same issue | |
| 17:26:35 | sean-k-mooney | if you do then we can confirm the bug | |
| 17:26:39 | sean-k-mooney | and create a repoducer | |
| 17:26:46 | sean-k-mooney | in the fucntional tests | |
