regXboirussellb: I'm pretty sure ^^^^ has everything you asked for, though maybe not the way you wanted16:15
russellbi just read through it16:15
russellbthe USE_SCREEN thing is unfortunate, but if it works ...16:16
russellbi was hoping it'd be in screen like the rest16:16
russellbbut sounds like that's more painful than i thought16:16
russellbin any case, this seems like a nice improvement if jenkins is happy16:16
regXboiack - I wasn't happy about the USE_SCREEN thing either, but it's really not happy if I tried to leave it in16:19
russellbright, and your comments explain it well16:20
russellbso fine for now16:20
russellblet's see what jenkins says16:20
Sam-I-AmregXboi: heh, that is sort of funny16:21
Sam-I-Amlooking at your patch16:21
regXboiSam-I-Am: I thought it was better than "hey, this is a massive hack"16:21
Sam-I-AmregXboi: well, it IS devstack16:22
*** tongli has joined #openstack-neutron-ovn16:22
Sam-I-Amthe whole thing is arguably a massive hack16:23
Sam-I-Amthere's some bikeshedding going on16:28
regXboiSam-I-Am: where now?16:31
Sam-I-AmregXboi: your patch16:31
regXboioh yeah - that's not that bad :)16:32
flaviof_Sam-I-Am apologies for any bikeshedding I may have caused. I trust regXboi to keep me straight.16:46
regXboiflaviof_: it's all good :)16:46

russellbi'm blind i think17:13
russellboh you added a space17:13
Sam-I-Ama space17:13
Sam-I-Amotherwise it parses as " x.x.x.x"17:14
Sam-I-Amwhich is fine for the neutron command, but not for the others that use it17:14

regXboiugh - looks like dsvm jobs are wedged again18:16
regXboi272265 has been sitting in the check pipeline for 2+ hours on the dsvm jobs, which both are stuck at "running devstack" ... so I'm guessing jenkins doesn't like my patch set :(18:16
Sam-I-AmregXboi: is this new?18:19
Sam-I-AmregXboi: now you cant use the excuse 'works in devstack'18:19
Sam-I-Ambut you can use 'works in MY devstack'18:19
regXboiSam-I-Am: unless it's my patch set, yeah, it's new18:19
Sam-I-Ami thought jenkins jobs time out after 90 minutes or something18:19
regXboiyeah it just failed... I'll need to go look at why18:21

Sam-I-Amrussellb: ping19:51
Sam-I-Amrussellb: did that patch to fix provider networks get merged?19:51
russellb               |   .·´¯`°Q(•_• )19:51
Sam-I-Amthe multi-port thing19:52
russellbnot yet, it's still queued up for review19:52
Sam-I-Amok, that might explain why i cant ping my router gw ip19:52
Sam-I-Amguess if i ditch this dhcp server maybe i can19:52
russellbcould be19:52
russellbyou won't be able to talk to any other ports on the same provider net on the same host right now19:52
russellbit's the top 3 patches listed on https://patchwork.ozlabs.org/project/openvswitch/list/?submitter=6763119:52
Sam-I-Amthe dhcp server is on .20 and the router gw on .21 on the same host19:53
Sam-I-Ami can only ping the dhcp ip19:53
russellbif you can ping one, should be able to ping the other, i would think19:53
Sam-I-Amcant ping it from the namespace either19:54
Sam-I-Ambtw this is using the native l3 agent19:56
Sam-I-Amwhich i havent used before19:56
russellbovn native l3 you mean?19:56
russellbok (no agent is why i'm asking)19:57
russellball ovs flow based19:57
Sam-I-Amso this ip would ride in that somewhere, rather than the nameapace like the dhcp agent19:57
russellbvirtual router should respond to ping though19:57
russellbip only exists in flows, not in linux stack19:57
russellbbut maybe it's broken for some reason19:58
Sam-I-Ami'm using the regular ways i would do this on neutron - router-create router, router-interface-add router priv-subnet, router-gateway-set router providernet19:58
* russellb nods19:58
Sam-I-Amwhen i do router-gateway-set, it pops an ip on the provider net, which i think i should be able to ping19:58
russellboh... that may not be working yet19:58
russellbit's probably not responding to arp19:59
Sam-I-Amdo secgroups apply to router ips?19:59
russellbthere's still some arp work not complete19:59
Sam-I-Amoh, that'd do it19:59
russellbsorry! sooooon.19:59
Sam-I-Amwould a fip on a vm work? or is that broken too20:00
russellbnot yet working for native l320:00
Sam-I-Amrather, a fixed ip that i can route to :)20:00
russellbfixed ip you can route to should work, yes20:00
Sam-I-Ami know nat is broken, so i was setting up a host route back to the private net20:00
russellbyes that should work20:00
Sam-I-Amproblem is, i cant get to my next hop :/20:00
Sam-I-Amthats sort of how this came up - ip route add 10.100.100/0/24 via <virt-outer-ip>20:01

*** jckasper has quit IRC20:03
russellbbtw if you want to apply my provider network fixes, i made a bundle for them ... https://patchwork.ozlabs.org/bundle/russellb/localnet/20:03

*** jckasper has joined #openstack-neutron-ovn20:04

*** jckasper has joined #openstack-neutron-ovn20:04
Sam-I-Amrussellb: is there a file in there?20:05
russellbyou should get a page with a header, a download link, a list of 3 patches20:06
Sam-I-Amnope, blank. wget sees a 404.20:07
Sam-I-Amrussellb: yeah blank page everywhere, on/off vpn, different browsers20:09
russellblooks like it's not public like i thought it was20:09
russellband i don't see how to make it public20:09
* russellb a patchwork noob still20:09
Sam-I-Amcan you fax it to me?20:10
russellbtry again20:10
Sam-I-Amwoot, works now20:10
Sam-I-Amso apply this... after cloning, prior to deployment?20:11
Sam-I-Amso my 2-liner patch has somehow become a lot more lines. funny how that works.20:11
Sam-I-Am(not just from your patch)20:11
Sam-I-Amworking on the ovn vagrant bits20:12
Sam-I-Amdurr, i'd have to modify the devstack bits to implement external patches20:34
Sam-I-Amwell, maybe not. perhaps i can work around this using shared dirs in vagrant20:35
Sam-I-Amcrap, still need to change devstack20:38
russellbyou can use http://github.com/russellb/ovs.git20:39
russellbbranch = origin/localnet20:39
russellbthat should get you the same thing20:39
Sam-I-Amthe devstack script doesn't support anything but master. however, i can fix that.20:40
Sam-I-Amthis seems like something useful20:40
Sam-I-Amthen i can also do a check for the repo already existing too20:41
Sam-I-Amoh, this is odd...20:41

regXboiok, so my patch kills br-int being created... that's not good20:48
russellbovn-controller creates br-int at startup (if you didn't create it yourself ahead of time)20:50
russellbnormally anyway.20:50
russellbyou know, unless you break something.20:50
regXboiyeah and I have, but I can't see exactly what :)20:51
regXboiat least, not yet20:51
regXboirussellb: wait20:52
* russellb waits20:52
regXboiovn-controller creates br-int?20:52
regXboithat's not what this plugin code says20:52
russellbwell, not if the plugin code does it20:52
russellbit *can* do it20:52
russellbi couldnt' rememember what our plugin did20:52
regXboithis plugin code is trying to create br-int right after ovsdb-server starts20:52
russellbah, ok20:53
russellbit probably has to because devstack expects it there to do it's *hand wave* setup stuff20:53
regXboiok, that implies that I need to look at the ovs logs for why the command is failing silently20:53
russellbyep, something probably just not starting up properly20:54
regXboiyeah... ovsdb-server would be my guess20:54
regXboigotta be it, but man, I'm not seeing anything obvious at this point20:57

russellbi'm not married to anything21:48
russellbhere's my thoughts...21:48
*** flaviof_ has quit IRC21:48
russellb1) having it in screen, and having logs preserved in jenkins jobs, is the ideal state.21:48
russellb2) if it can't be in screen, preserved logs are an improvement21:49
russellb3) current state, not in screen, no log preserved21:49
russellbpreference in that order21:49
russellbmake sense?21:49
russellb(applied to both ovsdb-server and ovs-vswitchd)21:49
regXboiyeah, we can't do #1 without major changes21:49
russellbfair enough21:49
regXboiI can do #2 without using run_process21:49
regXboiand I think I might go that route again21:50
russellbthat's still an improvement over #321:50
russellbyay devstack21:50
*** azbiswas has joined #openstack-neutron-ovn21:54
azbiswasrussellb: I saw that mestery changed the sample local.conf in networking-ovn/devstack to run OVN_L3_MODE=True, do the gate jobs also use this sample or it's disabled by default while running the gate jobs.21:57
Sam-I-Amif they used that option, they would break21:58
azbiswasok that makes sense21:58
Sam-I-Ambecause it no worky21:58
mesterySam-I-Am: Huh? That option works.21:58
mesteryOr maybe I've missed someting recently?21:59
azbiswasThe gate jobs require floating ip access21:59
azbiswasfor the VMs21:59
mesteryWell, that's a deficiency with the gate jobs, but yeah ...21:59
* mestery grumbles more about OpenStack's fascination with FIPs21:59

Sam-I-Amlast i looked ovn fell prey to the same hack that other neutron jobs use22:00

azbiswasI think a week ago22:00
mesterySam-I-Am: I've had no issues22:01
mesterySam-I-Am: I suspect a config issue22:01

mesteryazbiswas: Please do :)22:01
Sam-I-Ammestery: not sure what i'm missing here22:02
mesterySam-I-Am: The latest Vagrant has everything setup for provider networks, which is what I'm using22:02
mesterySam-I-Am: Try it with that?22:02
russellbthe gate does not use the sample config22:03
russellbit uses devstack/devstackgaterc to do its customizations22:03
Sam-I-Ami'm trying the vagrant boxes. i should be able to do router-create router, router-interface-add private-subnet, router-gateway-set router provider22:03
