10:17:00 kashyap gibi: Happy to be useful :)
10:32:49 sean-k-mooney alex_xu: they way the cyborg driver work there is no filtering so yes it would report any PF that the driver could manage
10:33:19 sean-k-mooney gibi: today nova owns the pf not neutron
10:33:35 sean-k-mooney neutron only owns the bandwidth
10:34:11 sean-k-mooney when we start reporting pci device to placement form nova we will be the ones creating the inventories for the VFs
10:43:30 gibi sean-k-mooney: today neutron creates the PF RPs and reports bandiwdth inventory on it, when we start reporting VF inventory from nova we need to agree with neutron who creates the PF RP or we have to create two RPs for a PF one from neutron perspective and one from nova perspective and then connect them somehow
10:44:23 sean-k-mooney gibi: nova need to do it because it needs to be consitient with non nic pci devices
10:44:42 sean-k-mooney unless we are going to specal case when the device has a physnet tag on the pci whitelist
10:44:57 sean-k-mooney which we coudl do but then we need two different code paths
10:45:20 sean-k-mooney gibi: ideally it would end up being one RP
10:45:49 sean-k-mooney unless we extend placemets data model with a way to link rps
10:54:04 sean-k-mooney gibi: quick question do you want a blueprint or a spec to track the machine type recodeing work?
10:54:56 sean-k-mooney as part of that i would like to start reporing avialble machine types as traits to placemnt and the schdlueling on that
10:55:49 sean-k-mooney e.g. if we do a move opperation on an exsting instance i want to ensure we land it on a host that supports that machine type
10:56:16 sean-k-mooney and if we are creating a new instance and you request a machine type in the image i want to ensure we land on a host that supports that too
10:56:29 sean-k-mooney both of which would be done by a prefilter
10:57:04 sean-k-mooney just addign the required tratit based on the instance system metadata or image metdata
11:00:12 gibi sean-k-mooney: sorry I was lunching.
11:00:19 sean-k-mooney no worries
11:01:02 gibi sean-k-mooney: agree that it would be nice to have on RP for one physical entity (like a PF or other PCI device)
11:01:29 gibi sean-k-mooney: I just wanted to note that this might requires changes both from nova and neutron
11:01:56 gibi btw placement has two ways today to link RPs, one is the parent-child relationship and the other is aggregates
11:02:44 sean-k-mooney yep altought i was thinking more of something like a symlink
11:03:00 gibi sean-k-mooney: I guess you don't need db schema rpc or REST API changes for the machine type recording work so I think a bp is enough
11:03:15 sean-k-mooney aggreate wont work because we can do member of in this case
11:03:39 gibi sean-k-mooney: yeah aggregates would be a bit ugly I agree
11:03:45 sean-k-mooney and parent-child likely wont work because we neither nova or neutron knows the uuid/name that will be used for the RP
11:04:05 sean-k-mooney that said we can work this out when we need too
11:05:56 sean-k-mooney gibi: are you ok with also doing the traits reporting and prefileter in the same specless blueprint.
11:06:13 sean-k-mooney ill write it up and i guess we can decide then
11:07:00 sean-k-mooney i assume a specless blueprint is also fine for the doc change to add the common profiles(nfv,realtime,modren) that we talked about too
11:07:35 sean-k-mooney im going to try and get those up before we resume today
11:11:19 gibi sean-k-mooney: the prefilter work is a bit of a grey area as I guess that needs a new config flag to enable since old computes will not report the traits
11:11:45 gibi so you might only want to enable the prefilter after all your computes are on V
11:12:11 sean-k-mooney yes although we could auto enable based on the min compute service version too.
11:12:16 gibi sean-k-mooney: specless bp for the hw:profile doc is totally OK
11:12:45 gibi sean-k-mooney: OK, note this upgrade wrinkel in the specless bp then I'm OK
11:13:19 sean-k-mooney sure will do. if i end up having to write a small spec its not the end of the world either but we will see what other think once its up
11:13:22 gibi sean-k-mooney: we will bring this bp up in the next nova meeting for approval so the rest of the team can complain if they need more words about it
11:13:45 sean-k-mooney sure works for me
11:13:50 gibi awesome
11:13:51 gibi thanks

12:30:31 gibi nova will continue the PTG session in 30 minutes in the Juno Zoom room.
12:32:47 sean-k-mooney crap already i guess i better get coffee and water ready so
12:34:25 gibi I've just did the same, water, coffee, and replaced the air in the room :)
12:34:57 gmann gibi: added one more topic (in the last) about removing the old and deprecated user level policy restriction. it was reminded by current ML thread.
12:35:26 gmann it should be ok to remove as we already doing warning for 4 years but good to check in PTG if anyone still using that way.
12:36:11 sean-k-mooney gibi: i bought a https://www.amazon.co.uk/Samson-SAQ2U-Microphone-Recording-Pack/dp/B001R747SG dnymic mic and stand so i can turn on my ceiling fan without out it being picked up without having to use a headset
12:37:17 gibi gmann: Is it OK to for you if I move that topic up to the first slot today where we anyhow talk about removals and deprecation?
12:37:43 gibi sean-k-mooney: that mic look serious :)
12:37:55 gmann gibi: yeah, that is totally fine.
12:38:00 gibi gmann: cool
12:38:04 gmann thanks
12:40:56 sean-k-mooney gibi: well i work form home permently and have calls regualarly but ya its a live stage mic that alot of twitch/game stream also use. for like 60 euro its good value too
12:42:14 openstackgerrit Merged openstack/nova-specs master: Make Feature Liaison optional https://review.opendev.org/730638
12:46:41 gibi sean-k-mooney: yeah, sounds like a good idea for a home office. I only do full home office due to COVID
12:48:48 gmann johnthetubaguy: you want to do quick fix on release name in https://review.opendev.org/#/c/732173/1
12:50:23 johnthetubaguy gmann: oops, looking
12:51:03 openstackgerrit John Garbutt proposed openstack/nova-specs master: Re-propose Unified Limits in Nova https://review.opendev.org/732173
12:53:06 alex_xu sean-k-mooney: gibi so for neutron sriov agent, I guess it has no way to discover the VF? since it won't read from libvirt
12:59:35 sean-k-mooney alex_xu: it does but not in a useful way
12:59:51 sean-k-mooney you have to list the netdev names of the PF in its config
13:00:05 sean-k-mooney and it uses iptool i think
13:00:17 gibi alex_xu: nova sends pci_slot information to neutron in the binding profile but yeah as sean-k-mooney said the pci whitelist is on nova side today to specify what VF and PF resource is usable
13:00:41 sean-k-mooney gibi: we do also send the pci addres in the pci_slot key
13:00:43 gibi so nova has the VF resource view
13:01:06 sean-k-mooney but that is used only when we are plugging or unplugging the port
13:07:03 artom gdi, y'all are talking and I can't hear you, can I?
13:11:16 alex_xu_ gibi: sean-k-mooney I'm just thinking of that the neutron sriov agent won't be able to manage vf even in the future. (not today, today nova manage it)
13:12:03 openstackgerrit Merged openstack/nova-specs master: Re-propose Unified Limits in Nova https://review.opendev.org/732173
13:16:23 sean-k-mooney alex_xu_: right i dont think it will or should manage the vfs
13:25:23 artom Dammit, you need a Zoom account to change your audio output settings >_<
13:29:07 sean-k-mooney artom: you should not
13:29:15 sean-k-mooney i can change mine and i dont have one
13:29:22 artom sean-k-mooney, in the client?
13:29:33 sean-k-mooney in both the client and the browser
13:29:40 artom sean-k-mooney, 'cuz I didn't find any way to do it. Even their official doc states you have to be logged in
13:29:46 dansmith advanced settings need an app I think
13:29:47 artom sean-k-mooney, https://support.zoom.us/hc/en-us/articles/201362283-Testing-computer-or-device-audio
13:29:50 dansmith including advanced network
13:30:05 sean-k-mooney artom: what are you trying to change
13:30:15 artom sean-k-mooney, audio output to go to my BT headphones
13:30:26 sean-k-mooney if you click the arror on mic
13:30:31 artom It was outputting to stereo out, where nothing is currently plugged in
13:30:34 sean-k-mooney then you can change the output
13:30:49 artom sean-k-mooney, oh christ, yes, it's there, you're right
13:38:17 stephenfin artom: your gain is waaaay too high
13:39:20 sean-k-mooney artom: the zoom app auto adjust your volume
13:39:43 sean-k-mooney or can so maybe look at that it in the extra options via the same arror menue
13:41:20 artom stephenfin, but my gainz are way too low :( Stupid gyms closing
13:41:35 stephenfin artom: you know where the door is
13:50:50 sean-k-mooney artom: you are now a bit quite but that is an imporvement
13:54:06 gibi gmann: it is policy stuff in the nova room
13:54:11 bauzas gibi: patches from dansmith about the compute 5.0 API bump https://review.opendev.org/#/q/topic:queens-rpc-bump+(status:open+OR+status:merged)
13:55:00 dansmith bauzas: yeah
13:55:06 gmann gibi: 1 min joinin
13:55:08 bauzas gibi: the proxy dansmith told https://review.opendev.org/#/c/541005/6/nova/compute/manager.py@7750
13:55:11 gibi gmann: we will discuss the policy stuff after the break at 5 minute past the hour
13:55:27 gibi gmann: so no rush
