russellbmestery: just saw all the backlog.  I think OVN_L3 by default is fine.  The l3 agent is a hack, and only half works anyway, but is necessary to make tempest pass for now.  We really want people playing with OVN_L3 on whenever we can13:08
*** dslev has joined #openstack-neutron-ovn13:30
mesteryrussellb: Coolio on all fronts!14:04
mesteryrussellb: With my vagrant patch and your provider networks patch, I can get a sweet little Vagrant setup running with VM access to the host over the provider networks.14:07
mesteryVery cool14:07

mesteryThanks for the patch to get networking-ovn working with stable/liberty regXboi, once it passes Jenkins I'll merge it since russellb has also +2'd it.14:58
russellbi'm hoping to do some tempest debugging today too14:58
mesteryrussellb: cool! I may have some time as well15:00
russellblooks like a lot is networks unable to delete because a port still exists15:03
russellbcould be a race i guess15:03
russellbgoing to try to add some debugging ...15:04

arosenrussellb:   do you know if  there  is a gw component from ovn that we can run which the ovn_l3_mode setting in the plugin configures the schema for?19:32
*** roeyc has joined #openstack-neutron-ovn19:34
russellbarosen: trying to understand the question ...19:36
russellbarosen: we could configure a virtual vtep gateway, sure19:37
russellbindependent of whether l3 mode is on or not19:37
arosendoes that let us replace the l3-agent right now?19:38
arosen(without nat just 1:1 ip?)19:38
arosensorry i'm asking about the component that replaces the l3-agent.19:38
arosencurrently we have the config flag in the plugin ovn_l3_mode which when false it uses the l3 agent19:41
arosenand when true it writes the expected values in ovn instead19:41
russellbwe can't completely replace l3 agent yet19:42
russellbmainly because no NAT19:42
arosenjust curious if there is any dataplane part for that, that is ready to be tested.19:42
russellbbut you can use l3 mode today, nothing else needed19:42
russellbit's all flow based19:42
aroseni figured i could work on getting the devstack script going with just the 1:1 with no nat19:42
russellbrouting between logical networks should be working fine19:42
russellbdoes that make sense?19:42
arosenyup, that makes sense. I thought there was a 1:1 nat that was ready but not 1-to-many19:43
russellbnope, zero nat ready19:43
arosenIn the future will there be a separate  binary that we will run on the gateway node?19:44
arosenthat implements the gateway functionality.19:44
russellbthat's very much TBD and not written down ...19:44
russellbthere's basically 2 paths of thinking19:44
russellb1) we have provider networks, and we could use ovs nat support to have support architecturally equivalent to DVR19:45
russellbthough we'd have to figure out how to handle a central snat point if you don't have floating IPs19:45
russellb2) expand the hardware_vtep schema to include L3 and NAT features, and use OVN gateways19:46
russellband also work on scaling and HA of gateways19:46
arosengotcha, thanks.19:46
russellbbased on my rough understanding of the world, #1 is more in line with what you'd expect coming from ML2+OVS19:46
russellbwhere as #2 is probably more like NSX historically19:46
russellbneither of these paths are complete and working though19:47
russellbbut that's kind of the lay of the land19:47
arosenyup i'd agree with that.19:47
*** dslev has joined #openstack-neutron-ovn19:47
arosenalso do you know if the patch that implements dhcp in ovn has merged?19:47
russellbit has not19:47
russellbben had some feedback, suggesting a different approach19:47
russellband it's on the authors to rework based on that feedback19:47
arosenawesome thanks for the info russellb :)19:48
russellbsure, any time19:48
arosenrussellb:  also do we know which tempest test is failing? Or is it just random each time?19:54
*** salv-orlando has quit IRC19:54
russellbnot consistent19:54
aroseni saw your patch trying to track down undeleted ports.19:54
russellbyeah .... i was just now looking at results19:54
russellbdidn't seem to do what i wanted19:54
arosenyea i noticed ;)19:54
arosenit looks like there are two ports there though.19:55
russellbhow can you tell19:55
arosen id: 692f9fd0-0a94-4b92-b5b8-9b8a1569291319:56
arosenone id19:56
arosensecond one19:56
arosenid: 63ef9b71-9666-4346-b942-5d6b2649c03919:56
arosenyou can see it prints to macs19:56
arosenit's hard to read.19:56
arosenone is the dhcp-port19:56
arosenport one: http://logs.openstack.org/05/269705/2/check/gate-tempest-dsvm-networking-ovn/05c21e9/logs/screen-q-svc.txt.gz?level=TRACE#_2016-01-19_18_50_22_01419:56

arosensame network: 40c3ea88-f448-4726-8543-f170cc6692be19:57
russellboh, ok19:57
russellbi was looking at a different NetworkInUse exception and it didn't dump any ports19:57
russellbhonestly, i thought i had all IPv6 tests disabled19:59
russellbbecause IPv6 support is known to be incomplete right now19:59
arosenyea this port is an ipv6 port20:02
*** salv-orlando has joined #openstack-neutron-ovn20:03
openstackgerritRussell Bryant proposed openstack/networking-ovn: Disable more IPv6 tests.  https://review.openstack.org/26983520:04

openstackgerritRussell Bryant proposed openstack/networking-ovn: tempest debugging, ignore...  https://review.openstack.org/26970520:14
russellbarosen: the 2 tests that failed weren't ipv6 tests though20:14
russellbso maybe i shouldn't disable them ...20:14
russellbheh, this looks like something i should fix ... http://logs.openstack.org/05/269705/2/check/gate-tempest-dsvm-networking-ovn/05c21e9/logs/screen-ovn-controller.txt.gz20:18
russellbdoubt it's related to failures at all though20:18
*** salv-orlando has joined #openstack-neutron-ovn20:19
openstackgerritAaron Rosen proposed openstack/networking-ovn: Revert "Add port 'up' and 'down' notification"  https://review.openstack.org/26985220:31
arosenrussellb:  I wonder if the failures could also be related to ^20:31
russellbdefinitely could be20:31
arosengoing to run to lunch bbl.20:31
russellbi don't remember if that's when it got worse20:31
