*** hujie has joined #openstack-meeting-409:05
oansonWe are in feature freeze, but due to the importance of this feature and seeing how close it is to completion, we want to try and merge it.09:05
gampelbut does not work properly09:05
oansonyuli_s, dingboopt you were testing this feature. Any comments?09:05
yuli_sI found a bug with double security group fields, so basically SG does not works for me09:06
*** markvoelker has quit IRC09:07
gampeloanson: I think we can merge it if it does not break the flow when set to work without SG09:07
oansongampel, We can do that09:07
oansonyuli_s, do you think it can be made to work by Monday?09:07
oanson(i.e. next Monday, the 18th?)09:07
gampelI see that there is a new patch from today what does it include ?09:07
yuli_sprobably yes09:07
gsagiewhy do we need to merge it if it doesnt work?09:08
yuli_sI have no tested the last patch09:08
nick-mayes, suggest to disable it by default in devstack.09:08
gsagiethis doesnt make sense09:08
*** hshan has joined #openstack-meeting-409:08
oansongsagie, if it can be made to work by the code freeze, merging it should expedite matters09:08
gsagieif its not enabled then its not in the feature freeze09:08
gsagiethats something needs to be decided now09:08
oansongsagie, not enabled by default09:08
*** spzala has joined #openstack-meeting-409:08
oansonstill available for anyone who wants to use it09:09
*** bobh_ has joined #openstack-meeting-409:09
gsagiewho will want to use it if its not working?09:09
nick-mait depends. if someone is willing to use it, but it doesn't work, it hurts.09:09
dingbooptoanson: I will take a look at the bugs after work.09:09
gampelwe will make it work this week09:09
gsagieso lets merge it when it works09:09
oansonThe plan is to get it to work by the code freeze09:10
yuli_sgsagie, I suppose it will be fixed ASAP09:10
oansonThen it will be available, working, but not enabled by default.09:10
oansonWe could enable it by default if we are sure of its stability09:10
yuli_sgsagie, agree09:10
gsagieso if thats the plan lets get it to work, why we need to merge code that is not working?09:10
gampelis yuanwei here ?09:10
*** javeriak has joined #openstack-meeting-409:10
gsagieif security groups is in the version then it needs to work, and we are past the deadline09:11
nick-maagree.09:11
oansonYes09:11
gsagieso we need to agree if its important feature enough or not09:11
gsagieif it is, we extend the deadline09:11
oansonI understood that we agreed that it was.09:11
*** baigk has joined #openstack-meeting-409:11
gsagiedingboopt: can you make security group work in the following 2 days?09:11
nick-mai think it's important.09:11
gampelyes it is and we need to extend the deadline only for SG09:11
gsagieDuan Kebo: can yuanwei can do it?09:11
Frank_DuanIf everyone finds a bug of SG, would you please forward it to me?09:12
gsagiewe need fast iterations on it09:12
Frank_DuanI will make sure there is someone working on it?09:12
gampelnot for other features that did not made the feature freeze09:12
*** sambetts|afk is now known as sambetts09:12
gampelyuli can you please share the bug here ?09:12
gsagieFrank_Duan: ok thanks, yuli_s and oanson will report bugs to you09:12
oansonIn addition to launchpad. It is helpful that the list is maintained09:13
oansonSG bugs can be marked critical so that we won't miss them.09:13
*** spzala has quit IRC09:13
raofeiIt's better to decide who should responsibility for this feature. It's better for yuanwei or dingbo to complete it fully.09:13
yuli_sgampel, In lport table we have 2 fields to save: sgids and security_groups. In my test they have different value.09:13
gsagieyuli_s: please share the bug you found, also i noticed that IPv6 is not supported need to add a bug for it as well09:13
*** bobh_ has quit IRC09:14
nick-mayes. ipv6 is not working.09:14
gsagiethe problem yuli_s showed me is that we have 2 fields for security groups09:14
*** wanghua has quit IRC09:14
gsagieneed to remove one09:14
Frank_DuanI have talked it with dingboot09:14
Frank_DuanHe is busy recently, so I and yuawei will fix bugs of sg09:15
gsagieFrank_Duan: ok great, please let me know if you need help09:15
oansonI am also available to help09:15
gampelOk thx we need to make it to work by the end of the week09:15
yuli_sok, great09:15
Frank_Duanthank you omer!09:15
oanson#action Frank_Duan yuanwei To finish SG app by end of week. oanson gsagie yuli_s to help where needed09:15
oansonAnything else on this topic?09:16
hshanthe reliability feature09:16
oanson#topic Reliability09:16
*** openstack changes topic to "Reliability (Meeting topic: Dragonflow)"09:16
oansonhshan: The stage is yours.09:16
*** baigk has quit IRC09:16
hshanthx09:16
gampelI think that we should delay it after the Mitcka  tag09:16
gsagiewhat is missing for that feature?09:17
gsagiehshan: ?09:17
hshanwe need to move the 'switch_features_handler' from openflow handler to ovsdb_monitor, reliability feature rely on that09:17
hshanthis is the last dependence of reliability feature09:18
*** zhurong_ has joined #openstack-meeting-409:18
oansonhshan: There is also the use of mod_flow and OFPFlowMod09:18
hshanoanson: yes09:19
gsagieok, so this is a quick fix09:19
gampelyou need to change all the app to use mod_flow09:19
gsagiemoving the switch features handler09:19
gampelthis is a big change09:19
hshangsagie: I'll add a new patch to do that09:19
oansongsagie: we should consider if we keep this event09:19
gampelI think that we should delay the reliability feature to after Mitka09:19
oansonthe sync_started and sync_finished should cover all cases.09:19
oansonBut this is definitely a change for after Mitaka, yes09:20
hshanmaybe we should merge it first, but don't enable it09:20
hshanwhat do you think?09:20
gampelhshan: I know that you worked very hard on this one But I feel that we need to merge it next week to master09:20
gsagiehshan: so change mod_flow and change switch_features_handler, what about L3 app?09:20
oansonhshan: I am afraid it may make the code unstable09:20
gampelI think that it is problematic because it changes some infrastructure code09:21
gampellike mod_flow09:21
oansonEven disabled, it has some changes within the code that have some effect09:21
oansonlike what gampel said :)09:21
gsagiegampel: but this we can disable09:21
gsagievery easily09:21
gampelI feel that this feature is not high priority like SG and it is too risky09:22
hshancurrently, the reliability feature's changing list is too long, i plan to divide it into several patches09:22
*** zhurong has quit IRC09:22
*** Shahid_ has quit IRC09:22
oansonActually, looking at the patch again, it looks like most changes are in new files09:22
oanson(I remembered an older version (: )09:23
hshanhuh09:23
gampelBut if you all think it is not we can consider adding it with disable flag09:23
gsagiehshan: ok, lets decide that its going to be in our next version, it doesnt mean its not going to be merged09:23
hshanyes, this reliability feature itself is simple09:23
nick-mamark it as experimental in the option. if it can be disabled and not affect the pipeline, i suggest we do it and continue to test by enabling it in devstack.09:23
gsagieits just going to be merged in next version to master09:23
oansonThe only problem if its disabled in the code in df_base_app. It has to be conditional anyway. So if we add that, it can also be merged.09:23
gsagienick-ma: i agree, i personally dont see why its not going to be easy to disable this feature09:23
nick-maneed to make sure it is working by code freeze.09:24
gampelOk so hshan add a patch that we can disable every thing and we coudl merge it this week09:24
gsagiehshan: the question is, why its important to get ir merged?09:24
gsagieit09:24
gsagieand is it working09:24
gampelI agree with the question ?09:24
hshanof course09:24
nick-maif it is not wokring by end of this week, let it go to next release. even if it is experimental, we need to make sure it is working then.09:25
gsagiehshan: did you change L3 application?09:25
gsagienick-ma: agree09:25
hshanI change mod_flow09:25
hshanall other apps use mod_flow09:25
gsagiehshan: ahh i see09:26
oansonhshan: This is in the latest patchset?09:26
hshanok09:26
gsagiehshan: so any app that uses the cookie will work09:26
Frank_DuanThe change is mainly in controller relibility itself. Modoify to other files is mior.09:26
gsagieyes i can see that, i will test this patch today09:26
hshanoanson: I think it is, all other job will be did in new patch09:27
gsagieand report by tomorrow and lets decide then09:27
gampelok so we agree to add it if it works and that it could be disabled and marked as experimental09:27
nick-maok09:27
Frank_DuanSo I agree we mark it as experimental feature.09:27
hshangsagie: you must wait for the new patches a little, I think I can finished it today09:27
gsagiehshan: please do and email me when its done09:27
gsagieand tell me which patch to use for testing09:28
hshangsagie: ok09:28
oanson#action hshan finish reliability and add option to disable reliability from configuration09:28
hshansure, I'll will09:28
Frank_DuanIt's also a important featuer if someone want to use df in any producion09:28
gsagiei will also look how we can safely disable it if it turns out not to work09:28
oanson#action gsagie test reliability feature09:28
gsagieFrank_Duan: we all agree its important, the question is it stable enough right now or needs to be merged in a week09:28
gsagieits really not that big delay either way09:28
gampeli agree09:29
gsagiebut we want a "semi" stable version for more testing09:29
gsagieand not to deal with logic bugs09:29
oansonThough I guess that if anyone uses it in production, they'll want a tagged version09:29
gsagiebefore the summit, thats all09:29
oansonrather than the ongoing master.09:29
*** Shahid_ has joined #openstack-meeting-409:29
gsagieoanson: yes but we can always add tags09:29
gampelWe can mark it as RC_109:29
oansongsagie: Not if we're in the middle of feature development and adding new bugs :)09:30
oansonAll right, I think we reached an agreement.09:30
gampeland cherry pick it when it is done to RC_209:30
Frank_DuanThis feature needs some time to mature.09:30
oansonAll features need to be heavily tested in the coming week09:31
Frank_DuanI do think it will be perfect in a few weeks.09:31
nick-maoanson: agree.09:31
oansonWe need to find and iron out as many bugs before the summit09:31
oansonAny more issues on this topic?09:31
oanson#topic Bugs09:32

Frank_DuanYes09:32
oanson#link https://bugs.launchpad.net/dragonflow09:32
oansonyuli_s, anything to report?09:33
Frank_DuanWe will focus on fixed bugs of these features.09:33
yuli_soanson, most of the bugs are taking care of09:33
yuli_swhen doing debugging, I am getting strange exceptions, I just send you one09:33
gampeloanson:  there is the unreported one about the publisher update frequency09:34
oansongampel, I am on that one.09:34
oansonyuli_s, please report these exceptions09:34
oansonThey may hide a larger problem beneath09:35
gampelFrank_Duan:  are you testing the selective proactive on multi node setup09:35
yuli_sI hope we will close all open issues09:35
yuli_soanson, yup09:35
oansonAnd it allows others to investigate and fix them09:35

oansonI see there are also 2 unassigned sg bugs.09:36
yuli_sfor example this one happens during debugging09:36
yuli_shttps://bugs.launchpad.net/dragonflow/+bug/156850609:36
openstackLaunchpad bug 1568506 in DragonFlow "sg test bug 2" [High,New]09:36
hujieI have test all feature for basic function in the middle of March based on redis in multi mode environment09:36
oansongampel, testing is next topic09:36
oansonLets focus on bugs, and then we can get to it :)09:36
gampelOpps09:36
Frank_DuanGampel, we only tested redis09:36
Frank_Duanand will test zmq later09:36
gsagieokie lets go to testing09:36

gampelShlomo_N: Can you share the status of your performance testing so far09:41
Shlomo_Nyes, sure09:41
*** mfedosin has quit IRC09:42
Shlomo_NLast week I have tested for 4 scenarios: E-W (L2 and L3), N-S and SNAT09:42
Shlomo_NAfter twicking the linux kernel, I have managed to get near 90% line utilization09:43
Shlomo_NHere are the results:09:43
Shlomo_NL2VMVM7.39Gb/s09:43
Shlomo_Noops09:43
Shlomo_NL2: 7.39Gb/s09:44
Shlomo_NL3: 7.24Gb/s09:44
Shlomo_NNorth-South: 6.98Gb/s09:44
gampelit  it cross node09:44
gampel?09:44
Shlomo_NSNAT: 8.38Gb/s09:44
Shlomo_NYes, all tests are cross node only09:44
oansonOn a single 10G line?09:44
nick-mageneve or vxlan?09:44
Shlomo_NYep, the lab I'm using it based on 10Gb/s and vxlan09:45
gampeldid you get the line rate with multi VM traffic09:45
gampel?09:45
Frank_DuanShlomo, do you have the performance data of neutron + ovs agent?09:45
Shlomo_NI got near line rate with multi vm traffic09:46
*** scsnow__ has joined #openstack-meeting-409:46
nick-mawhy does snat get more bandwidth/sec? i don't understand.09:46
Shlomo_NFrank_Duan: I have, but it's based on 1Gb/s lab09:46
*** scsnow_ has quit IRC09:46
gampelFrank_Duan: I think next will be to test with SG and then DVR09:47
*** GB21 has quit IRC09:47
*** woodard has joined #openstack-meeting-409:47
oansonShlomo_N: Do you also have CPU usage statistics for these tests? Is the bottleneck now the line width?09:47
Shlomo_Nnick-ma: probably because we have only single VMSwitch in the way09:47
gampelShlomo_N:  i agree with nick-ma: why is the SNAT and DNAT not the same it is alll centralized right ?09:47
Shlomo_Noanson: the bottleneck is not the line bandwidth09:48
Frank_DuanYes, gampel. we also need to compare them with performance data of neutron + ovs agent09:48
Shlomo_Ngampel: yes. DNAT wasn't tested09:48
gampelyou said North-South: 6.98Gb/s  and SNAT: 8.38Gb/s09:49
Shlomo_Nyes09:49
gampelFrank_Duan:  yes next we will do reference implementation with DVR09:49
Shlomo_Nprobably because we have only single VMSwitch in the SNAT scenario09:50

gampelshlomo is working on automating the testing you could use his work09:50
gampel Shlomo_N: will you be able to upload it to the DF repository09:51
Shlomo_NFrank_Duan: how many servers you have there?09:51
Shlomo_NSure, I will09:51
Frank_Duanwe have 3 severs with 10GE if09:51

openstackMeeting started Mon Apr 11 15:09:02 2016 UTC and is due to finish in 60 minutes.  The chair is banix. Information about MeetBot at http://wiki.debian.org/MeetBot.15:09

*** openstack changes topic to " (Meeting topic: kuryr)"15:09
openstackThe meeting name has been set to 'kuryr'15:09
banixmspreitz: salv-orlando i started the meeting for the sake of having a log for the conversation as a meeting15:09
banixdo you have anything yopu want to discuss. mspreitz you updated your patch. anything to discuss?15:10
mspreitzFYI: I attempted a precise write-up of the two network policy proposals, see https://docs.google.com/document/d/1cTA_c1qahzZ9nDI-h6Vp9-9_kCB-kk1cw91K0qRjI8415:10
mspreitzI also posted some brief remarks on the Raven devref15:10
mspreitzAm willing to expand, but the author is not here now.15:10
banixsalv-orlando: have you had a chance to look at the Raven devref: #link https://review.openstack.org/#/c/301426/15:11
mspreitzI updated the T1 devref, and am looking for feedback on that and the precise semantics writeup15:11
*** javeriak has quit IRC15:11
salv-orlando                  banix: not yet. planning to do it this week15:11
mspreitzI also updated the T0 PR15:11
banixmspreitz:  is this the link? #link https://review.openstack.org/#/c/290172/15:12
mspreitzYes, that is the devref for T1 and T215:13
mspreitzThe T2 part probably still needs a little work to track my realization from last week.15:13
*** iyamahat has quit IRC15:13
mspreitzwell, maybe more than a little.  Am still not happy about the multi-tenancy stuff.15:13
banixok, I think the main review items are the Raven and the T1 & T2 devrefs linked above15:14
banixThe magnum integration spec got merged: #link https://review.openstack.org/#/c/269039/15:15
mspreitzI would also like review of my attempt at a precise writeup of network policy.  Questions keep arising of what net pol is, and I tried to put forth a clear answer.15:15

mspreitzThe network policy stuff is mainly discussed in the kubernetes network SIG and related Google docs15:16
banixmspreitz: if you have a link it will be good to share here15:17
mspreitzThe network SIG's mailing list is here: https://groups.google.com/forum/#!forum/kubernetes-sig-network15:17
banixmspreitz: thanks15:17
mspreitzA broader set of pointers is at https://github.com/kubernetes/kubernetes/wiki/Special-Interest-Groups-%28SIGs%2915:17
*** piet has joined #openstack-meeting-415:17
mspreitzYou probably need to join something to see those15:18
banixthe other item we had was adding support for existing Neutron networks and that is merged.15:18
banixThe last item worth bringing up is the design sessions at Austin15:18
mspreitzThere is also the issue of support for Liberty Neutron15:18
*** fawadkhaliq has quit IRC15:18
banixas mspreitz mentioned the support for existing Neutron networks uses Neutron tags and as such requires Mitaka. Working on making this available for Liberty through the old hack of using Neutron network name15:20

banixI don’t have anything else to add other than that if this is not a good time for our meetings we should look for a time slot where we can have most of the community attend15:22
mspreitzIt works fine for me, but we need to hear from those not here now.15:22
banixmspreitz: it is possible but I would say it will be difficult. salv-orlando did that in one of the summits if i recall correctly15:23

Sukhdevjroll : GM16:02
Sukhdevwe discussed about 4 patches last week16:02
SukhdevI reviewed them over the weekend - they look good16:03
Sukhdevany chance we can get them some core love and get them merged within April?16:03

Sukhdevdevananda : you have been busy testing them as well - any thoughts?16:04
devanandaSukhdev: I've found a few issues with the network driver patch, and posted comments last week16:04
devanandaI see there are new patches up, which I need to retest this week16:04
*** mohankumar has joined #openstack-meeting-416:05
Sukhdevdevananda: I will try to give them a spin as well16:05
*** neelashah has quit IRC16:05
devanandaas far as the hardware tests I've been doing - the environment is up but some kinks are still being worked out with our deployment. I'm hoping by EOW, and no later than the summit, we'll have some significant testing done against it16:06
Sukhdevdevananda : that will really nice16:06
Sukhdevdevananda: are you testing with OVN?16:07
Sukhdevanybody else is testing these patches as well?16:08

devanandaunsure - we were at that point in the build last week, and I haven't sync with the team yet today16:12
* jroll bbiaf16:12
Sukhdevdevananda: ah I see - if you need any help, feel free to ping me16:13
sambettsI think its in a fairly stable state now, its probably at a point where I can confidently rebase my interface and not have to worry about having to drastically change it again16:13

* Sukhdev looking16:15
devanandatwo issues:16:15
devananda- network drivers are loaded at instantiation of the Node object, but should be loaded when the Conductor starts16:15
*** neelashah has joined #openstack-meeting-416:15
devananda- upgrade path requires a CONF change, and not doing so breaks ironic-conductor silently16:15
*** fawadkhaliq has joined #openstack-meeting-416:16
*** armax has quit IRC16:16
*** fawadkhaliq has quit IRC16:16
sambettsFirst issue solved by ensuring that enabled_network_drivers is processed at conductor start16:17
sambettsright?16:17
*** SimonChung has joined #openstack-meeting-416:17
devanandayes, except the new interface isn't loaded there16:17
devanandaso it may take some refactoring - -I'm not sure16:17
sambettssecond by having a check in the init for the network drivers if cleaning is enabled: ensure conf is there16:17

devanandaif enabled_network_drivers were instantiated within CondctorManager.__init__, that would address the first one16:19
devanandait would also cause the second one to result in an error message and Condcutor's refusal to start today16:19
*** rtheis has quit IRC16:19
devanandawhich would be better than a silent failure, but also, I htink the wrong solution16:19
devanandaI'd like to ask -- do we actually need to define the cleaning_network_uuid for the FlatNetworkDriver ?16:20
*** paul-carlton1 has joined #openstack-meeting-416:20
sambettsdevananda: https://review.openstack.org/#/c/285852/36/ironic/drivers/modules/network/flat.py its needed for add_cleaning_network16:21
Sukhdevdevananda : hasn't this been the case before?16:21
devanandaas this patch stands, it adds a new requirement to Ironic -- all deployments must set a Neutron Network UUID16:21
devanandaeven if they do not have Neutron in the environment16:21
devanandabecause flat networks worked just fine without Neutron before16:21
devanandaie, in the case of a stand-alone ironic16:21
jrolldevananda: we do, that's a thing today16:21
devanandaor a private single-tenant cloud16:21
jrollafaik16:21
devanandajroll: no, it's not16:21
jrollhow are cleaning ports created then?16:22
vdrokdevananda: yep, before it was required only when neutron dhcp is used and cleaning is enabled16:22
jrollright, that16:22
devanandavdrok: exactly16:22
vdroks/before/now16:22
devanandaso if I'm using bifrost (with no neutron) I don't need to set this16:22
jrollso yeah, I guess it might need a refactor so that only happens if neutron dhcp is in use16:22
devanandaafter this patch, I have to pass in a fake UUID for this variable16:22
devanandas/variable/CONF option/16:22
sambettswe just need an if statement in https://review.openstack.org/#/c/285852/36/ironic/drivers/modules/network/flat.py L36 that checks if cleaning enabled right?16:23
jrollnod16:23
devanandacool16:23
jrollsambetts: well, it should be able to work without that config, if noop dhcp provider is used16:23
jroll"it" being cleaning16:23
jrollclint was also requesting that the config accept a name16:23
jrollbut idk if he put that in the review16:24
sambettswhile we're hacking adding the cleaning network via the dhcp provider16:24
sambettsonce that is deprecated and we're calling the network provider for cleaning networks directly then is cleaning enabled is your only flag for disabling it right?16:24
vdrokjroll: he did not, and idk if it's worth adding this too right now, lots of stuff there already, we could change it later if needed16:25
*** iyamahat has joined #openstack-meeting-416:25
jrollvdrok: sure16:25
jrollsambetts: well, it actually depends on the dhcp provider really :/16:25
jrollmaybe we shouldn't be moving that, hrm16:25
sambettspersonally I think that the dhcp should be moved inside the network driver16:26
jrollor perhaps we need to fold dhcp provider things... yeah16:26
jrollI feel like we can do that after all of these things, with the one catch being this config16:26
vdrokthe easiest thing would be to meove the cleaning net check inside cleaning methods instead of init right?16:27
devanandavdrok: or into the conductor's __init__ ?16:27
*** yamahata has joined #openstack-meeting-416:27
sambettsbut then it fails during runtime and I'd love to have it just blow up the conductor at the start if i've got an invalid config16:27
Sukhdevsambetts +116:28
devanandasambetts: yes16:28
devanandaDriverLoadError will only abort the conductor if raised during __init__16:28
*** fawadkhaliq has joined #openstack-meeting-416:28
devanandaso if we don't check this during conductor init, it will just get logged over and over again (which is what I'm seeing right now)16:29
sambettshaving an if CONF.cleaning_enabled in the FlatProviders init would allow it to work if they are using the Ironic config correctly16:29
devanandasambetts: IFF we also instantiated FlatNetworkProvider during ConductorManager.__init__ -- which we don't today16:29
sambetts(I'm assuming that these drivers will be loaded at conductor load)16:29
*** armax has joined #openstack-meeting-416:29
devananda:)16:29
sambettswhich I really want them to be16:29
devananda++16:30
jrollfwiw, I'm surprised the drivers aren't loading at conductor init, they look like they should be already16:30
*** unicell has quit IRC16:30
vdrokdriver_factory.NetworkInterfaceFactory() in init_host?16:30
jroll^ yeah, that's what's needed16:30
jrollah, that isn't done today16:31
jrollmy mistake16:31
Sukhdevit seems like simple fix, but, will require good amount of testing -16:32

Sukhdevdevananda : thanks for articulating the issue - when I saw the comments on p35, I thought your issue was addressed16:36
Sukhdev#topic: VLAN aware servers16:36
*** openstack changes topic to ": VLAN aware servers (Meeting topic: ironic_neutron)"16:36
SukhdevWe discussed this last week, and I followed up in Neutron16:36
Sukhdevthought I give a quick update16:37
SukhdevSo, OVN has this implemented16:37
Sukhdevthe author who was looking for OVS got pulled into something else16:37
Sukhdevhence, it has not been getting much attention in the neutron side -16:38
Sukhdevbut, last week I raised the priority because of Ironic need16:38
SukhdevWe are looking into separating out the OVS implementation from the API -16:39
Sukhdevthis means, the basic core API will be implemented so that who ever has need for it can use it16:39
Sukhdevwhich works best for us for Ironic integration16:39
SukhdevI am also trying to get a design session on this topic so that we can all discuss16:40
Sukhdevas you know neutron is one of the biggest project, and, the number of sessions tend to be tight -16:41
*** minwang2 has joined #openstack-meeting-416:41
Sukhdevbut, I will continue to hope and push for one :-)16:41
jrolloh! we did get the cross-project session for this on tuesday16:41
sambetts++ for generic API, my concern with the existing API is that they define a translation between what comes out of the VM and what is carried on the neutron network, which of course doesn't work for most BM cases because we can't run anything between the node and the switch16:42
Sukhdevjroll : cool - thanks for sharing this news16:42

sambettsNeutron summit session ideas are here: https://etherpad.openstack.org/p/newton-neutron-summit-ideas16:43
sambettsOurs is L3416:44
sambettsSukhdev: any idea when the decision will be made for neutron?16:44
Sukhdevsambetts : correct, present proposal was by OVN (and OVS team) - hence, very VM centric16:44
Sukhdevsambetts : I think the deadline for the session schedule is 4/17 -16:45
sambettsSukhdev: Yeah, we (Cisco) have an interest for making in more generic for SRIOV too, because that has the same problem as BM16:45
sambettsmaking it*16:45
sambettsSukhdev: So we should know by next meeting then16:46
sambettsawesome :)16:46
Sukhdevsambetts : yup16:46
SukhdevBTW, I saw rosella replied on ML that she will pick up the work on VLAN aware VMs - she was driving it earlier16:47
Sukhdevthis means we will get traction on this -16:47
sambettsGreat!16:47
SukhdevWhat I am trying to do is to pull all the players in a room so that we can all lay out the requirements and work together so that duplicated work can be avoided16:48
Sukhdevso that it is VLAN aware server (not just VMs)16:48

ihrachyswe did similar thing for neutron-*aas repos in Liberty too21:03
tonybmriedem: fixtures right? IIRC that hurt neutron as well21:03
ihrachysso neutron is all constrained too21:03
*** ninag has joined #openstack-meeting-421:03
bknudsonsomeday keystone might support constraints in tox.ini21:03
mriedemyes, fixtures 2.021:04
tonybI might do some checking to see who is constrained in liberty21:04
mriedemtonyb: same idea here for cinder in liberty https://review.openstack.org/#/c/303932/21:04

ihrachyssummit should be the right time21:06
mriedemi have them in open discussion21:06

mriedemi imagine the thurs fishbowl session for stable will be talking about the outcome of the tuesday sessions and making plans21:06
bknudsonit used to be everything broke when the lib was released21:06
tonybmriedem: Yeah do the planning on Tuesday and hash out the details then21:06

mriedemyeah https://review.openstack.org/#/q/status:open+project:openstack/nova+branch:stable/liberty21:08
mriedemlyarwood was asking for that this week21:09
mriedemthere are some open +2ed reviews that i'd like to get in first21:09
ihrachysmriedem: so nova plans to sort MTU out in L?\21:09
tonybmriedem: last time I looked there were 3-4 of your that had one +2 that looked like good candidates ....21:09

mriedemihrachys: this? https://review.openstack.org/#/c/285710/21:10
ihrachysyeah21:11
mriedemi haven't really decided since it introduced problems in mitaka for dpdk21:11
mriedembut in mitaka neutron also changed the default mtu value which is what broke dpdk21:11
*** fawadkhaliq has quit IRC21:11
mriedemit wouldn't be the same issue in liberty by default21:11
mriedemthe issue was this other change https://review.openstack.org/#/c/289370/21:12
*** fawadkhaliq has joined #openstack-meeting-421:12
ihrachysok. I also suspect it would require some more stuff on neutron side, but I would need to check. I just have not bothered to backport that assuming nova won't go with their part.21:12
mriedemi don't think neutron can backport changing the default mtu value21:12
mriedembasically, on the nova side, i think we'd have to make sure https://review.openstack.org/#/c/289370/ is in if we did https://review.openstack.org/#/c/285710/21:13
ihrachysyeah. but we then can at least provide guidance to users on how to achieve proper setup21:13
ihrachysit's a matter of some conf changes, but that should be ok for those who want it sorted for L21:13
mriedemihrachys: i don't know all of the mitaka mtu change details, but are you suggesting backporting the default mtu value config change in neutron from mitaka to liberty?21:14
ihrachysmriedem: not really. but I think we had other fixes as well.21:15
ihrachysmriedem: like the ones setting MTU on interface driver managed interfaces (f.e. for router or DHCP ports) based on network MTU21:15
ihrachysso with those in, users would 'only' need to change config values to get proper behaviour21:16

anteayapart of this is me saying hello, and participating in the stable meeting21:21
tonybanteaya: :)21:21
anteaya:)21:21
mriedemthe stable maint team is mostly just a sanity check on project-specifc core team nominations21:21
mriedemat least IMO21:21
tonyb#action tonyb to sync up with Rob re horizon-stable-core21:21
mriedemand that's how i treated it before21:21
anteayacool21:22
tonybYeah I fell like we need to see $person doign stable reviews befoer they're added to core21:22
ihrachysthe text seems rather clear to me. if that's not enough for projects, I guess it's wise to ask for suggestions.21:22
tonybthat part isn't called out specifically21:22
david-lylein the past (maybe long past) PTLs were added automatically21:22
mriedemi don't think just because someone is the PTL of a project that qualifies them for stable core21:22
david-lyleis that no longer the case?21:22
ihrachystonyb: I think it's an implicit part of the culture in the project that you don't get +2 before enough reviews are done21:23
mriedemlike tonyb said you have to actually be doing stable branch reviews and show you know the policy21:23
anteayayeah that makes sense, knowledge drift is a thing21:23
tonybihrachys: sure but you can +2 on master so .... there is some argument :/21:23
anteayafor instance I didn't know about the section in the project team guide until now21:23
anteayathanks mriedem21:23
mriedema core can +2 an api change on master, sure,21:24
mriedemthat does'nt mean that core should +2 a backport of said api change on stable21:24
