14:21:56 <openstack> The meeting name has been set to 'neutron_l3'
14:22:03 <liuyulong> #topic Announcements
14:23:17 <liuyulong> We have merged the OVN Convergence spec.
14:23:25 <liuyulong> #link https://review.opendev.org/#/c/658414/
14:23:48 <liuyulong> And we also have some ovn patches are getting to the review list.
14:24:21 <liuyulong> So I'd like to add a new topic in the L3 meeting, for OVN L3 functionality.
14:25:36 <liuyulong> I will send this to the mail list to see the opinions from others.
14:26:00 <liuyulong> OK, let's move on.
14:26:09 <liuyulong> #topic Bugs
14:27:30 <liuyulong> #link https://bugs.launchpad.net/neutron/+bug/1853637
14:27:30 <openstack> Launchpad bug 1853637 in neutron "Assign floating IP to port owned by another tenant is not override-able with RBAC policy" [Medium,New]
14:28:16 <liuyulong> This should be fixed IMO, I will take this.
14:28:41 <haleyb> liuyulong: hi, sorry figured you had canceled
14:29:10 <bcafarel> o/
14:29:27 <liuyulong> It will be required for some hierarchical operators role.
14:29:32 <bcafarel> liuyulong: slaweq will not be around for the meeting, he will catch up on logs later
14:31:19 <liuyulong> Next one:

14:31:40 <openstack> Launchpad bug 1853613 in neutron "VMs don't get ip from dhcp after compute restart" [Undecided,New]
14:32:37 <liuyulong> haleyb, hi
14:32:53 <liuyulong> haleyb, a long local meeting just blocked me.
14:33:03 <haleyb> np
14:33:15 <liuyulong> For this DHCP bug, we have noticed same issue.
14:33:38 <liuyulong> If a compute node was down, and up again.
14:34:23 <liuyulong> Some VM will not get (dhcp) the address, due to the flow re-install slow progress.
14:34:36 <haleyb> and this is the iptables_hybrid driver it looks like
14:35:35 <liuyulong> The dhcp client inside the VM will try to request 3-5 times, and all get failed, then just VM just start without IP address.
14:36:50 <liuyulong> We have one solution is make the NIC config a static setting inside the VM during the first start (booting) procedure.
14:38:14 <liuyulong> And another solution is to start 10-20 VMs each time, yes as a trunk, until all get finished.
14:39:28 <haleyb> he claimed this started after https://review.opendev.org/#/c/645408/ - the fix we did for ovs agent restarts
14:39:33 <liuyulong> Local flow based-DHCP mechanism can not work, since physical host restart will lose all the flow, it needs to be re-install or sync data from neutron-server.
14:41:51 <liuyulong> Yes
14:42:55 <liuyulong> I noticed that, but I'm not sure if it is really related.
14:46:54 <liuyulong> Let's investigate this and try to reproduce it.
14:47:17 <haleyb> i guess in generic terms it's a race condition when rebooting a compute node
14:47:29 <liuyulong> No more L3 bugs from bug deputy.
14:48:27 <liuyulong> And after a quick scan of LP bug list, also no L3 bugs.
14:49:00 <liuyulong> #topic On demand agenda
14:51:42 <haleyb> i don't have any items
14:52:44 <liuyulong> haleyb, should we add a section in this meeting for OVN L3 functionality?
14:53:44 <haleyb> liuyulong: sure, on the gaps?
14:55:06 <liuyulong_> Not only gaps, but also some bugs, features or anything else need to be mentioned or discussed for the team.
14:55:41 <haleyb> +1
14:57:05 <liuyulong_> Mainly for L3, since OVN has almost full functionalities of networking. We cannot cover them all. : )
14:58:10 <liuyulong> OK, then, let's end here, we only have one hour time slot.
