17:02:02 <vks1> hi all
17:02:15 <igordc> hi
17:02:20 <dianyu> hi
17:02:22 <LouisF> hi all
17:02:23 <bcafarel> hello
17:03:00 <LouisF> #topic API reference
17:03:26 <LouisF> pcarver: what is status?
17:04:28 <LouisF> #topic Tap SF
17:04:38 <LouisF> vks1: what is status?
17:05:03 <vks1> LouisF: I have debugged the test case with extension. it's failing
17:05:20 <vks1> talked with amotoki, he said we should do in 2nd week of oct
17:05:25 <vks1> he is on vacation
17:05:52 <LouisF> vks1: ok thanks
17:06:10 <LouisF> #topic SFC graph
17:06:26 <LouisF> igordc: how is SFC graph progressing?
17:06:51 <bcafarel> I saw a few W+1 here
17:07:15 <LouisF> bcafarel: yes i expect this will merge soon
17:07:32 <bcafarel> nice
17:08:02 <LouisF> ok moving on
17:08:08 <igordc> yep just waiting for it to merge
17:08:20 <vks1> has anyone tried any extension in networking-sfc ?
17:08:20 <bcafarel> that means we should start reviewing the NSH patch then?
17:08:26 <LouisF> igordc: thanks
17:08:36 <LouisF> bcafarel: yes that is next item
17:08:44 <LouisF> #topic NSH work
17:09:07 <bcafarel> :)
17:09:11 <csun> Which version of OVS includes NSH support?
17:09:26 <LouisF> all please review https://review.openstack.org/#/c/373465/
17:09:38 <igordc> csun: 2.8, if you use the userspace datapath
17:09:56 <csun> I see, thinks.
17:10:58 <LouisF> we should get ovs with nsh tested to make sure in is in queens
17:11:10 <bcafarel> ack, will try to take a look at it next week
17:11:19 <LouisF> bcafarel: thanks
17:11:28 <igordc> thanks bcafarel
17:11:56 <igordc> we need to find a nice way of generating nsh packets
17:12:36 <igordc> tho for the networking-sfc esting of it, OVS itself can be the one
17:12:38 <csun> igordc: Do you have a good example of how to generate nsh packets?
17:12:58 <LouisF> igordc: if nsh encap is specified the ingress classifier should generate nsh packets - right?
17:13:02 <igordc> and the SFs can also be running OVS+NSH simply decrementing the index and giving the traffic back
17:13:24 <igordc> LouisF: yes exactly;, <-- csun this
17:13:52 <LouisF> igordc: nsh-aware sfs is another issue
17:14:14 <LouisF> does your implementation support nsh-aware SFs?
17:15:00 <LouisF> or does it just implement proxy functionality?
17:15:15 <igordc> LouisF: both
17:15:38 <bcafarel> by setting correlation on the PPG I suppose?
17:15:39 <igordc> LouisF: it will expect packets to come back with a decremented SI
17:15:39 <LouisF> igordc: how are you testing nsh-aware SFs?
17:15:45 <igordc> bcafarel: yeah
17:16:13 <igordc> LouisF: I'm not yet testing that... Daire started working on it during her placement but then it finished
17:16:28 <csun> Any known issues with nsh support?  I’d like to do some testing about the change.
17:16:43 <igordc> LouisF: I'm not sure how much and if I will have time to do proper testing with the SFs
17:16:46 <LouisF> igordc: i see that there will be a lot of interest from SF vendors
17:17:06 <igordc> csun: would you like to test networking-sfc + nsh-aware VMs?
17:17:39 <csun> Yes, I’d like to give a try.
17:18:03 <LouisF> csun: sounds like a good idea
17:18:11 <LouisF> csun: thanks
17:18:14 <igordc> csun: cool cool, ping me if you need anything
17:18:30 <igordc> csun: #networking-sfc
17:18:44 <csun> igordc: I would definitely need your help.
17:19:51 <igordc> csun: are you Ching Sun?
17:20:06 <csun> igordc: Yes.
17:20:29 <igordc> alright
17:21:39 <LouisF> #topic Transparent SF
17:21:54 <LouisF> this work is progressing
17:22:36 <LouisF> #topic OVN-SFC work
17:22:58 <LouisF> looks like John is not on the channel
17:23:12 <LouisF> #topic other items
17:23:53 <dianyu> I have hitten an error when launch a new instance on Horizon as following: Error: No sql_connection parameter is established. Anyone has similar error or idea?
17:24:39 <LouisF> dianyu: is this on the master?
17:24:46 <dianyu> with newest master networking-sfc and devstack stable/pike
17:25:23 <igordc> dianyu: use master devstack
17:25:47 <LouisF> has anyone else encountered this?
17:26:03 <csun> I encountered the same thing.
17:26:21 <LouisF> csun: on stable/pike?
17:26:31 <csun> I am using stable/pike devstack.
17:26:47 <csun> master networking-sfc
17:26:48 <bcafarel> it may be some leftover installed packages from stable/pike run
17:27:06 <dianyu> igordc: will try
17:27:16 <bcafarel> with everything on master I restacked 2-3 days ago and VMS booted fine
17:27:27 <csun> I will try to use master devstack today.
17:27:50 <LouisF> igordc: thanks
17:28:17 <LouisF> dianyu: can you try that
17:28:41 <dianyu> LouisF: yes, definitely
17:28:49 <LouisF> dianyu: thanks
17:29:06 <bcafarel> other topic, I chatted a bit with other people on split tempest plugins ( https://governance.openstack.org/tc/goals/queens/split-tempest-plugins.html )
17:29:07 <LouisF> ok, any other items to discuss?
17:29:29 <bcafarel> we are indeed expected to be in the "migration done" list :)
17:29:50 <bcafarel> I can take a look (it should mostly be splitting git history and repo gates configuration)
17:30:08 <LouisF> bcafarel: that would be great, thanks
17:30:47 <LouisF> ok, anything else?
17:31:23 <LouisF> ok thanks all
17:31:31 <LouisF> bye all
17:31:33 <dianyu> thanks everyone
17:31:40 <csun> bye all
17:31:41 <bcafarel> thanks, and bye!
17:31:49 <igordc> bye all
