13:02:10 bauzas sean-k-mooney: correct me if I'm wrong, but I see a last revision of generic mdevs that is only due for fixing pep8 mypy issues because we were not explicitely returning None ?
13:02:36 bauzas plus the fact you moved the documentation bit out of the last change into a specific WIP change, right?
13:02:37 sean-k-mooney bauzas: yes
13:03:22 sean-k-mooney stephenfin: was ok with adressing the doc update in a seperate change so suggested we split it out to not block the feature
13:03:33 sean-k-mooney since the doc update can happen after FF
13:04:23 sean-k-mooney bauzas: effectivly what stephenfin would like is if we have a stuf file that explains vgpu are now implemented in terms of generic mdevs and then links to mdev doc
13:04:45 sean-k-mooney bauzas: if we want to have specific vgpu docs we can keep them int vgpu doc
13:05:26 sean-k-mooney bauzas: but ya i did not actully change any of your codes functionality form where you left it just the mypy update
13:08:49 bauzas sean-k-mooney: no worries at all, my question was just for understanding the touched bits, and to make sure I wasn't missing crucial bits
13:09:06 bauzas sean-k-mooney: thanks for having followed up while I was working on my tan
13:09:38 sean-k-mooney i ment to get to it sooner but i did not see the pep8 failure until recently
13:09:44 bauzas (which was a difficult effort as I discovered to having traveled to the worst raining place in France apparently)
13:10:00 bauzas a perfect Irish weather for the first week
13:13:14 sean-k-mooney haha we hit 27+ a few days while you were off
13:13:47 gibi now that is perfect ^^ :)
13:14:17 kevinz kashyap: Thanks a lot! Good to hear that!
13:14:33 sean-k-mooney its been a pretty good summber all things considered in ireland this year at least on teh weather front
13:15:06 bauzas sean-k-mooney: are you honestly saying I got an irish weather while you were getting a mediterrean weather ?
13:15:15 bauzas life is unfair
13:15:24 sean-k-mooney very much so
13:15:48 bauzas pro-tip : we usually joke about french Britain rainy weather
13:16:10 bauzas but please reconsider the basque country as more wet than britain :)
13:16:11 sean-k-mooney with that said my tomatoes got hit by blight last week and are all starting to die but we still got some of the harvest
13:17:10 sean-k-mooney its the result of having heat then lots of humitity for 2 and ah half weeks
13:17:15 bauzas sean-k-mooney: hah, I'm jealous
13:17:28 bauzas we got a ridiculous harvest this year for our tomatoes
13:18:37 bauzas but, let me ask one question : any series to look at now besides kevinz's ask ?
13:18:46 sean-k-mooney i think we have got like 2-3 kg form 20-25 plants which is not greate but i know some have just had there entire lot of plants wiped out
13:18:53 bauzas gibi: I guess I'm all done for you with your pps series, right?
13:18:59 sean-k-mooney bauzas: https://wiki.openstack.org/wiki/Meetings/Nova#Agenda_for_next_meeting

13:19:05 sean-k-mooney i just put a few on the meeting adgenda
13:19:36 sean-k-mooney bauzas: the review priortiy lable merged a few days ago so im suggeesting we start using that to track them
13:19:39 gibi bauzas: I have my reviews for the pps so you can focus on other things
13:20:13 bauzas sean-k-mooney: excellent
13:20:46 bauzas gibi: that's the question I'm asking, I don't know what other things to do
13:20:55 opendevreview Federico Ressi proposed openstack/nova master: [WIP] Investigate on Nova quota limits problem https://review.opendev.org/c/openstack/nova/+/806683
13:21:21 bauzas unified limits would get my interest, but we're two days from FF, and this is unfortunate I didn't had time to look at it before
13:21:25 gibi bauzas: things in NeedsCodeReview state are a good candidates https://launchpad.net/nova/+milestone/xena-3
13:21:39 bauzas will find candidates, no worries
13:21:54 gibi ack

14:30:32 sean-k-mooney stephenfin: just an fyi im going to rebase https://review.opendev.org/c/openstack/nova/+/669411 and adress gibi comment, this looks ok to me so should be an easy win
14:31:09 sean-k-mooney ill see how hard it is to add that final check after binding
14:32:01 gibi I only skimmed that patch, but if you make it fresh then I can try to look at the
14:32:55 sean-k-mooney its most of the way there if it misses its not the end of the world but also its small and low risk so if we can get it done then its a nice to have
14:33:43 sean-k-mooney im currently goign trhough the set of blueprint and patches that seam close and seeing if i can get them over the line
14:33:55 sean-k-mooney but this is lower on my list of priorities
14:35:35 gibi ack
14:52:56 opendevreview Merged openstack/nova master: Remove module level caching https://review.opendev.org/c/openstack/nova/+/806394
15:04:52 spatel is anyone running DPDK on Intel X710 nic, i would like to buy so looking for some good feedback ?
15:10:11 spatel currently i am using Intel® 82599 10 Gigabit Ethernet but it has limitation of rx/tx queue which is max=2 per VF
15:50:29 gibi fyi nova weekly meeting starts in 10 minutes here in the channel
15:51:34 sean-k-mooney spatel: x710 used ot be the primaly nic that intel used for dpdk development so its fully supported but its a few years old now and they have proably moveed tothe 800 seriese they lauched last year
15:52:10 sean-k-mooney spatel: this is the dpdk docs for that nic https://doc.dpdk.org/guides/nics/i40e.html
15:52:14 spatel do you know how many rx/tx queue does x710 support ?
15:52:32 spatel x710 is older so may be cheaper for me to get it up and running with dpdk
15:52:56 sean-k-mooney x710 is much much newer then 82599
15:53:10 sean-k-mooney but i know the queue count is actul configurable in the driver
15:53:22 sean-k-mooney im not sure what its set too by default for VFs
15:53:34 spatel 82599 has hard limit for 2 rx/tx queue per VF
15:53:47 sean-k-mooney ah Reserved number of Queues per VF (default 4)
15:53:57 spatel Look like x710 has 16 per VF (default 4) but we can change it so that is good
15:54:00 sean-k-mooney https://doc.dpdk.org/guides/nics/i40e.html#runtime-config-options
15:54:31 spatel nic look like x710 is good choice for me in low cost
15:55:20 sean-k-mooney the 72x revision are nic if you need 25G or think will upgrade at some point
15:55:41 sean-k-mooney they are not much more expensive and also are slightly more power effeinct
15:56:20 spatel 10G is more then enough, my whole requirement is to run DPDK and remove SRIOV dependency which doesn't support security-group and bonding
15:56:33 spatel hmm
15:57:29 spatel let me see what i can get because all depend on budget but good to know
15:57:48 spatel sean-k-mooney i have successfully deploy SRIOV with OVN and its working great
15:58:01 sean-k-mooney good to know
15:58:11 sean-k-mooney do not use it for PF passhtouhg however
15:58:21 sean-k-mooney we need to remove that at some point
15:58:39 spatel remove it from where? NOVA?
15:59:36 sean-k-mooney ovn
15:59:52 sean-k-mooney it allows vnic_type=direct-physical but does not manage it properly
15:59:52 spatel I have question for you how does OVN provide redundancy for network node? currently my compute nodes are network node so lets say i have 10 compute nodes then how OVN schedule gateway chassis?
16:00:06 bauzas 8 seconds before the meeting ;)
16:00:13 bauzas so, wait a bit for the answer :p
16:00:20 spatel :)
16:00:21 sean-k-mooney that proably better asked in neutron too
16:00:34 bauzas gibi: you're late
16:00:34 spatel thank you!
