15:04:32 <Swami_> #topic announcements
15:05:04 <Swami_> Mitaka milestone3 release this week
15:05:50 <Swami_> Last week we were in the mid-cycle and made some head way on the live migration patches.
15:06:13 <Swami_> We got a nova core to review the nova patch for live migration.
15:06:58 <Swami_> We also addressed some of the multi-node failures with respect to a volume based live migration.
15:07:18 <Swami_> That test skip substantially reduced the failures for the multinode.
15:07:51 <Swami_> Any other announcements this week
15:08:39 <obondarev> Swami_: cool
15:08:57 <Swami_> If there are no announcements we should proceed.
15:08:58 <haleyb> none from me, just need to go through the wiki and clean it a bit myself
15:09:08 <obondarev> Swami_: what are the fixes for volume backed live migration issue?
15:09:34 <obondarev> Swami_: was it fixed in nova?
15:09:53 <Swami_> obondarev: We saw that this test was failing on all neutron, neutron-dvr and for nova as well. So we went and filed a bug and skipped this test.
15:10:17 <Swami_> #link https://review.openstack.org/#/c/284450/
15:10:23 <obondarev> Swami_: I think a saw a couple of bugs on it before
15:10:47 <obondarev> ok, skipping seems a valid path for now
15:11:09 <Swami_> obondarev: yes pushed that patch and it made it through.
15:11:52 <Swami_> Thanks to haleyb for the patch
15:12:14 <Swami_> #topic Bugs
15:12:42 <Swami_> There are no new bugs this week.
15:12:54 <Swami_> So we are still working and reviewing the old bugs.
15:13:08 <carl_baldwin> I saw one last night
15:13:21 <carl_baldwin> #link https://bugs.launchpad.net/neutron/+bug/1549311
15:13:24 <openstack> Launchpad bug 1549311 in neutron "Unexpected SNAT behavior between instances with DVR+floating ip" [Undecided,In progress] - Assigned to Hong Hui Xiao (xiaohhui)
15:13:44 <carl_baldwin> I didn't get a chance to tag it yet.
15:14:00 <Swami_> carl_baldwin: yes I think this one was filed around midnight, so I might have missed it.
15:14:21 <carl_baldwin> It wasn't tagged
15:14:38 <carl_baldwin> But the author showed me it
15:15:11 <Swami_> carl_baldwin: ok fine, I will add it to the list.
15:15:26 <carl_baldwin> Thanks
15:15:37 <Swami_> Also there was another bug that was filed by adolfo, on router interfaces seen on compute nodes even if there are no valid VM on the subnets.
15:15:49 <Swami_> #link https://bugs.launchpad.net/neutron/+bug/1552085
15:15:50 <openstack> Launchpad bug 1552085 in neutron "Router Interfaces Are Instantiated in Compute Nodes Which do not need them." [Undecided,In progress] - Assigned to Adolfo Duarte (adolfo-duarte)
15:16:52 <Swami_> The server is sending all the interfaces related to the router, even if there are no VMs on those interfaces to the agent and the agent adds it to the ovs-bridge
15:17:01 <Swami_> I think adolfo has a patch for it.
15:17:21 <Swami_> #link https://review.openstack.org/287012
15:18:52 <Swami_> The next in the list is the live migration bug.
15:19:09 <obondarev> wait please
15:19:24 <obondarev> the bug says "The presence of the other two unused interfaces does not affect functionality"
15:19:47 <obondarev> wondering should we add more complexity to the code because of this
15:20:28 <Swami_> obondarev: we were just thinking it is simple check that we can do before sending all the interfaces and hopefully it would not be complex.
15:20:35 <obondarev> ok I'll leave a comment on review
15:20:45 <Swami_> obondarev: thanks.
15:20:55 <obondarev> yeak but it is additional db call
15:21:07 <Swami_> obondarev: agreed.
15:21:09 <obondarev> sorry, let's move on
15:21:20 <Swami_> #link https://bugs.launchpad.net/neutron/+bug/1456073
15:21:21 <openstack> Launchpad bug 1456073 in neutron "Connection to an instance with floating IP breaks during block migration when using DVR" [High,In progress] - Assigned to Swaminathan Vasudevan (swaminathan-vasudevan)
15:22:13 <Swami_> mriedem has included a tempest test and it seems to have some issue to validate the live migration with floatingip, so that is holding up right now.
15:23:03 <Swami_> #link https://review.openstack.org/#/c/286855 - here is the tempest patch that introduces the ssh when floatingip is assigned.
15:23:38 <Swami_> I need to take a look at how the test is created. By looking at the logs I don't see any floatingip created in the first place with this test.
15:24:08 <Swami_> Is there any tempest experts here, to solve this problem.
15:25:08 <haleyb> <crickets>
15:25:49 <Swami_> haleyb: same here
15:26:26 <haleyb> i'll take a look
15:26:38 <Swami_> haleyb: ok, thanks
15:27:02 <Swami_> The next one in the list is

15:27:48 <Swami_> haleyb: any updates on this bug
15:28:53 <haleyb> There are two patches, both need updates, I will look at them
15:29:10 <Swami_> haleyb: ok thanks
15:29:35 <Swami_> do you have those patches handy to post it here.
15:29:40 <haleyb> https://review.openstack.org/#/c/277657/
15:29:50 <haleyb> i thought there was another, might be mis-remembering
15:30:41 <Swami_> haleyb: thanks

15:31:44 <obondarev> I guess I need to address some comments on nova patch
15:31:47 <Swami_> obondarev: are these patches seeing any movement.
15:31:54 <Swami_> obondarev: thanks
15:32:12 <obondarev> neutron patch slowly gets +1s :)

15:33:33 <openstack> Launchpad bug 1462154 in neutron "With DVR Pings to floating IPs replied with fixed-ips" [High,In progress] - Assigned to ZongKai LI (lzklibj)
15:34:05 <Swami_> #link https://review.openstack.org/246855
15:34:51 <Swami_> This patch is moving a bit slow. I think carl_baldwin and I discussed about this patch during the mid-cycle, we might have to speed up this post mitaka.
15:34:55 <carl_baldwin> I'm hoping to get stephen-ma to help me with this one.  stephen-ma are you around?
15:35:20 <carl_baldwin> stephen-ma: Do you have a DVR setup we could try this patch out on?
15:35:22 <stephen-ma> carl_baldwin: what help do you need
15:35:41 <Swami_> carl_baldwin: I also suspect that this issue has anything to do with the bug 1549311 - are they inter related.
15:35:42 <openstack> bug 1549311 in neutron "Unexpected SNAT behavior between instances with DVR+floating ip" [Undecided,In progress] https://launchpad.net/bugs/1549311 - Assigned to Hong Hui Xiao (xiaohhui)
15:35:47 <stephen-ma> carl_baldwin: I created a two node setup yesterday.
15:36:35 <carl_baldwin> Swami_: I think there is some link between the two from what xiaohhui told me.  But, that was late last night and I haven't had time to process.
15:37:24 <carl_baldwin> stephen-ma: Let's get together later today to play around with the patch.  Will you have some time this afternoon?
15:37:33 <Swami_> carl_baldwin: yes that's what I suspect as well
15:37:41 <stephen-ma> carl_baldwin: yes I have.

15:38:35 <carl_baldwin> stephen-ma: I'll ping you.
15:38:57 <Swami_> #link https://review.openstack.org/#/c/254439/ - This patch is under review
15:39:29 <Swami_> That's all for the bugs list
15:40:33 <Swami_> #topic Gate_failures
15:41:23 <Swami_> As we announced earlier we have reduced the multi-node failures substantially now.
15:41:32 <Swami_> Still we have some minor issues in the gate.
15:42:01 <Swami_> There is couple of traces seen in the server side, with respect the gateway not found for the subnet.
15:43:06 <Swami_> I think we need to add a bug to this, if there is not one already filed
15:43:28 <haleyb> agreed, as the other bugs have mostly been fixed
15:43:43 <Swami_> haleyb: yes.
15:43:52 <obondarev> good news
15:44:00 <Swami_> I don't think we have anything more on the gate failures at this point.
15:44:11 <Swami_> #topic Open-discussion
15:45:16 <Swami_> It would be great if we can get the tempest test for live migration get going, so that the live migration patches can land.
15:45:36 <Swami_> Also this week let us focus on the FIP and snat related issues.
15:46:16 <Swami_> Anything else.
15:46:29 <haleyb> Swami_: the server-side patch for live migration was approved yesterday btw
15:46:43 <Swami_> haleyb: yes I did see it.
15:47:00 <Swami_> That is good.
15:48:01 <Swami_> haleyb: obondarev: carl_baldwin: I am planning to cleanup the wiki. I just wanted to remove the closed-bugs, the list is becoming too big. What do you think.
15:48:18 <obondarev> Swami_: ++
15:48:58 <haleyb> +1 from me, i'll update the gate failure section when you're done
15:49:19 <Swami_> ok, I will clean it up
15:49:30 <Swami_> Thanks, that's all I had for today.
15:49:39 <Swami_> Did I miss anything?
15:50:30 <Swami_> If we don't have anything to cover, we can end the meeting.
15:50:45 <Swami_> Thanks everyone for joining the meeting and will meet next week.
15:50:53 <Swami_> until then bye.
