Sam-I-Amrussellb: re 279841 - i never saw replication of those entries in bash profile15:54
russellbi need to make it so my /pong command takes an argument so it will prefix it with a nick...15:54
Sam-I-Ami did at one point, then i moved that line15:54
russellbSam-I-Am: if you run stack.sh again it would, right?15:54
Sam-I-Amyeah15:54
Sam-I-Amdoes anyone do that?15:55
russellbi do15:55
russellbsometimes.15:55
Sam-I-Amoh, i usually find running stack.sh again ends up in sad pansa15:55
Sam-I-Ampanda15:55
russellbsometimes.  :)15:55
Sam-I-Ambut if thats a use case, i can see the duplication15:55
russellbi'm lazy and tend to use the same devstack VM until i destroy it15:55
Sam-I-Ami usually throw away my devstack vms15:55
* russellb nods15:55
russellbthat's cleaner.15:55
russellbespecially if you have it automated with vagrant or whatever15:56
Sam-I-Ami do15:56
russellbright :)15:56
russellbi don't15:56
Sam-I-Amwell then15:56
* Sam-I-Am patches russellb 15:56

Sam-I-Amyeah saw that15:57
Sam-I-Amthe only real problem there is inter-vm networking15:57
Sam-I-Amand the dreaded mtuuuuu15:57
russellbbut maybe it's good that i still run devstack manually15:59
russellbdon't want to *only* support vagrant15:59
russellbthat's what i tell myself anyway15:59
Sam-I-Ami've run it manually too... in a vm. and try to avoid running stack.sh again.16:00

Sam-I-Amvm on provider net. pung from controller node that has an ip on the provider net.16:58
russellboh!16:59
russellbyes.16:59
russellbthat's because there's a, um, little bug with SGs and provider networks16:59
russellbwhere we .. um .. don't enforce them at all :-p16:59
russellbit's in the bug tracker though16:59
russellbeasy enough to fix, but it'll get fixed as a side effect of han zhou's work to simplify provider net integration17:00

mesteryrussellb: Does the current provider network design with localnet ports limit things to a single provider network per hypervisor?20:50
russellbmestery: noi20:52
russellbno20:52
mesteryI thought I read that as a restriction of localnet ports (e.g. only one per host)20:52
mesteryI'm likely confusing something20:52
russellbyeah.. it's not a restriction20:52
russellbyou can have as many as you want20:52
mesteryrussellb: Does this need to be corrected? https://github.com/openvswitch/ovs/blob/master/ovn/ovn-sb.xml#L121820:53
mesteryrussellb: I'll send a patch if so.20:53

russellbit has been a little bit of a moving target20:53
mesteryYes20:53
mesteryI'm trying to catch up on some things on the ML now (I think like you), so things are bleeding through a bit20:53
russellbthis is going to simplify things even more -- https://patchwork.ozlabs.org/patch/582095/20:53
* mestery looks20:54
russellbbasically, makes it so we don't have a logical switch per port on a provider network20:54
russellbit's going to make a big difference for larger environments20:54
mesteryOh yes it will! That's great!20:54

UdayHi, question on installing networking-ovn with devstack, having issues around tox.21:02
Uday2016-02-15 20:59:03.678 | + cd /opt/stack/networking-ovn 2016-02-15 20:59:03.678 | + tox -egenconfig 2016-02-15 20:59:03.955 | genconfig create: /opt/stack/networking-ovn/.tox/genconfig 2016-02-15 20:59:05.784 | genconfig installdeps: -r/opt/stack/networking-ovn/requirements.txt, -r/opt/stack/networking-ovn/test-requirements.txt 2016-02-15 20:59:05.784 | ERROR: could not install deps [-r/opt/stack/networking-ovn/requireme21:02
UdayI have tried updating tox and that did not help.21:02
Sam-I-AmUday: what happens if you clone networking-ovn and run tox -e genconfig ?21:03
Udaythe issue is that there are some custom patches applied in networking-ovn that I cannot afford to lose (these are basically someone else's patches).21:05
UdayIt'll be a pain to manually compare those and repatch21:05
Udaybut if that's the only way to go, then I can give that a try21:05
Sam-I-Amwell, if those patches impact it, we need to figure out why21:07
Sam-I-Amif it works with stock code, its not a problem with ovn21:07
lrichard21:07
Sam-I-Amwell, current ovn21:07
Uday@sam-i-am, this seems to be an issue with installing deps, not with running the ovn code. The same code has run previously. The difference this time is that I ran cleanup.sh after unstack.sh.21:12
Sam-I-Amoh, heh...21:13
Sam-I-Amymmv on that one...21:14
Sam-I-Ami've never had much luck with un-stacking21:14
