ianong | rossella_s: I have another question. is devstack the only way to deploy openstack? I tried modifying the code directly in /usr/lib/python2.7/site-packages/neutron/ and it did reflect.... But in the case of adding plugins, neutron/setup.cfg needs to be modified, right? Is there another way other than devstack? | 08:10 |
AJaeger | ianong, there's a great Installation Guide at http://docs.openstack.org | 08:11 |
AJaeger | and there are commercial solutions. The question is for what reason do you want to deploy it. | 08:11 |
*** dguitarbite has quit IRC | 08:12 | |
rossella_s | ianong: I thought you wanted to test your changes, not to deploy openstack | 08:12 |

rossella_s | ianong: if you are interested in deploy, AJaeger gave you good links | 08:13 |
rossella_s | ianong: if you wanna test your changes...well in my experience devstack is the easiest way. You can modify the code directly and even debug it | 08:13 |
rossella_s | ianong: for a plugin you can also create a package that installs only the plugin not neutron or copy the plugin files manually, which is ok for testing I guess | 08:15 |

I referred from OpenDayLight plugin: https://github.com/openstack/neutron/commit/791256cb671630ff70c941272df89717a7216eeb I guess I have already done it but I cannot test to see if it works. Looks like devstack is my only hope. hehe.. | 08:25 |
rossella_s | ianong: you can use unit tests...but that's like the first step. Then you have to run it in a stack. Devstack is the easier way. Otherwise you can deploy a cloud and apply your changes but that's harder | 08:27 |
rossella_s | ianong: in my experience devstack is the easiest way... | 08:29 |

pcm__ | matrohon_: yes | 14:28 |
matrohon_ | pcm__ : I wass wondering if there was an explanation of the architecture used with VPNagent, service driver, device driver etc... | 14:28 |
matrohon_ | pcm__ : i didn't fin anything usefull on the wiki | 14:29 |
pcm__ | matrohon_: No. It pretty much follows the same architecture as the reference (openswan) implementation. | 14:29 |
garyk1 | markmcclain1: hi, can you please look at my comments on https://review.openstack.org/94018 | 14:29 |
markmcclain1 | garyk1: looking | 14:30 |
garyk1 | i think that the patch and the one aobe it is very useful. hopefully we will not need to wait for infra (and they too will have to do the same chnages) | 14:30 |
matrohon_ | pcm__ : I was wondering what would be the good path to implement another type of VPN : IPVPN | 14:30 |
pcm__ | matrohon_: I think there are some basic drawings that Nachi did. | 14:30 |
markmcclain1 | garyk1: you make a good point…my understanding from doug was that waiting was better | 14:31 |
matrohon_ | pcm__ : that's what I'm looking for :) do you have a link? | 14:31 |
pcm__ | matrohon_: (Curious) what is IPVPN? | 14:31 |
matrohon_ | pcm__ : MPLS based VPN | 14:31 |
pcm__ | matrohon_: Let me look. I think I had cloned one of Nachi's diags too. | 14:32 |
pcm__ | matrohon_: Here's one of Nachi's old docs: https://docs.google.com/presentation/d/1uoYMl2fAEHTpogAe27xtGpPcbhm7Y3tlHIw_G1Dy5aQ/edit#slide=id.gc2bc6c2e_0176 | 14:33 |

garyk1 | my two cents from jogo was that the debug translations are also very costly. so it may be worthwhile doing it noew | 14:33 |
matrohon_ | pcm__ : thanks very much, it will definitly help! | 14:34 |
markmcclain1 | garyk agreed there is non-trival cost concerned about churn | 14:34 |
pcm__ | I have this one, from the summit (as backup info): https://docs.google.com/document/d/18IYwbE5vM2FYdw4Qhg9I3ufd8IeqSinU8MyIplOV6rA/edit | 14:34 |
pcm__ | matrohon_: Sure. BTW, join in on the L3 IRC chats as you can get involved in any VPN discussions. | 14:35 |
markmcclain1 | garyk1: because the are building infra to differentiate the strings a bit | 14:35 |
pcm__ | matrohon_: I know there was talk at the summit (Nachi's session) about Juno VPN items. | 14:36 |
AJaeger | HI neutron cores, could you review https://review.openstack.org/#/c/94934/ , please? This will make the daily "Imported Translation from Transifex" update significantly smaller. | 14:36 |
matrohon_ | pcm__ : great, usefull too! I didn't know that VPN topics were discuss during the l3 meeting! I will try to attend. Thanks | 14:36 |

zzelle | larsks, i am not sure for OVS bridges | 15:02 |
larsks | zzelle: it sure is some odd behavior. | 15:03 |
zzelle | larsks, but "kernel" bridges uses the lower mac of all interfaces connected to the bridge | 15:03 |
*** packet has joined #openstack-neutron | 15:03 | |
larsks | zzelle: Yeah, I'm familiar with that. But in this case, there's doesn't appear to be any other interface -- anywhere -- with the MAC address that the bridge is picking up. | 15:03 |
zzelle | larsks, with OVS bridges, it seems bridges uses the lower mac of all interfaces or a random if connected to nothing | 15:03 |
larsks | Also, the mac is changing on br-ex when we're deleting a port on br-int. Which is just...argh. | 15:04 |
*** yongli has quit IRC | 15:05 | |
zzelle | larsks, oh ! i read too fast and incorrectly ... strange change on br-int has effects on br-ex | 15:06 |
zzelle | larsks, are you sure redhat like support correctly ovs interface defined through config file ? | 15:08 |
zzelle | s/interface/bridge | 15:09 |
larsks | zzelle: i can replicate this behavior just using ovs-vsctl and ip commands, so it seems independent of the config files. | 15:09 |
*** jkary1 has quit IRC | 15:09 | |
*** igor_ has quit IRC | 15:09 | |
larsks | zzelle: in fact, it looks like *any* ovs operating (e.g., "ovs-vsctl add-br br-foo") causes the mac address on br-ex to flip. | 15:10 |
larsks | zzelle: ...always to the same value until destroying/re-creating the bridge. | 15:10 |

*** jobewan has joined #openstack-neutron | 15:13 | |
larsks | zzelle: It doesn't look like it. That is, if I run "ip link set br-ex addr $MACADDR", this updates the "mac_in_use" field in that output... | 15:13 |
larsks | zzelle: and the mac it keeps switching back to does not show up anywhere in, e.g., "ovs-vsctl list Interface" | 15:14 |

sballe | SumitNaiksatam, Do you knw how far the team is with the ServiceVM implementation? | 16:36 |

SumitNaiksatam | we dont track the service VM on a weekly basis in the advanced services meeting | 16:37 |
SumitNaiksatam | we would like to but we run out of time | 16:37 |
SumitNaiksatam | there is a separate meeting for that, which is at an odd hour for most of us | 16:37 |
SumitNaiksatam | long story short, i am not as much up to speed | 16:37 |
SumitNaiksatam | that said there were patches posted during icehouse | 16:38 |
SumitNaiksatam | i can dig them up for you | 16:38 |
SumitNaiksatam | of course, the current direction is to do this in stackforge | 16:38 |

busterswt | trad511: if that value is blank, i would expect to see the gq interface in the integration bridge rather than br-ex, that qg interface would have some internal vlan tag and there should be flows on both that correspond to vlan 3111. | 20:13 |

trad511 | busterswt: i had thought that as well, but didn't see it move with value change and service restarts. | 20:14 |
busterswt | yeah, sometimes i've seen it not move, and just use the router-gateway-clear and router-gateway-set command to get it to go where it needs to | 20:14 |

busterswt | trad511: cool, lemme know! | 20:16 |
trad511 | busterswt: do you know if behavior of setting external_network_bridge is to automagically set/show gw in horizon as well? | 20:16 |
*** dgollub has quit IRC | 20:17 | |
busterswt | trad511: in terms of the port showing as DOWN in horizon? not sure i understand the question | 20:17 |
busterswt | trad511: or do you mean, if you manually set the external network in the l3 config, will it show as the default gateway network in horizon? | 20:19 |
trad511 | busterswt: yes that's my ? | 20:20 |
busterswt | trad511: not that i'm aware of. it's really only needed when you have more than one provider network whose router:external attribute is set to true. You're instructing the l3 agent to use that particular external network. If you only intend to have one external network, you can leave that value blank as well. | 20:21 |
*** a_le has quit IRC | 20:21 | |
busterswt | trad511: i think horizon will only show eligible "gateway" networks (the ones with router:external=true) | 20:22 |
trad511 | busterswt: that is basically what i thought. have done so many tests to try to debug the vlan tag issue that i begin to suspect too many things ;) | 20:22 |
busterswt | trad511: i know what you mean. i really think the gateway clear/set commands will do it for you. you can also try creating a new router and attaching it to the same external network and see if qg goes to br-int | 20:23 |

trad511 | busterswt: weird, setting gateway_external_network_id, restarting l3 agent and creating a router still put the port on br-int and did not automatically set external_gateway_info (but adding gw after router creation did) | 20:39 |

bjornar | Anyone with a ospf routed datacenter willing to give me some input? | 20:40 |
busterswt | trad511: qr will definitely end up on br-int with the router-interface-add command. the external gateway info won't be set until you do a router-gateway-set | 20:41 |
busterswt | trad511: and then qg will end up on br-int ( or should, in this case) | 20:41 |
harlowja_ | salv-orlando saw the email, i hope for a good usage of taskflow in neutron (cheers!) :-) | 20:41 |
salv-orlando | I hope too | 20:42 |
trad511 | busterswt: roger that, and confirmed that it does… so what's the purpose of setting gateway_external_network_id? to force that agent to only grab that net off the queues? | 20:42 |
harlowja_ | salv-orlando and your right btw, its a library | 20:43 |
*** nati_ueno has joined #openstack-neutron | 20:43 | |
harlowja_ | *no shooting required, ha | 20:44 |
salv-orlando | harlowja_: I was pretty sure of that ;) What I was not 100% sure about is that mistral in a standalone service with its own rest endpoint | 20:44 |
busterswt | trad511: to bind that external network to that agent, so to speak. in havana it was 1:1 network to agent. think that's changed, so i'm not sure what it looks like in icehouse | 20:45 |

busterswt | your external provider network is type vlan or vxlan? | 20:49 |
openstackgerrit | Carl Baldwin proposed a change to openstack/neutron-specs: Improve the responsiveness of the L3 agent https://review.openstack.org/95267 | 20:50 |
trad511 | busterswt: vlan. in full disclosure this is ml2 w/ vxlan and vlan, but provider net is vlan and pretty much defined the way specified in your article http://developer.rackspace.com/blog/neutron-networking-vlan-provider-networks.html. thx for that info online btw | 20:51 |
*** irenab has joined #openstack-neutron | 20:51 | |
harlowja_ | salv-orlando ya mistral is that, with its own DSL (and eventually they are goign to use taskflow internally, so there are some neat possilbilities here) | 20:51 |
harlowja_ | salv-orlando that usage of taskflow in mistral is being worked out (they POCd there own thing just to get rolling) | 20:52 |
*** a_le has joined #openstack-neutron | 20:52 | |
harlowja_ | i agree its a different usage pattern, internals of openstack will easier integrate with taskflow than mistral (at least at the current time, maybe someday in the future this won't be the case) | 20:53 |
busterswt | trad511: haha thx for reading. little outdated now. and your provider network segmentation id is 3111? | 20:53 |
salv-orlando | cool, I see. This just reinforces that mistral should probably not be looked as an alternative to neutron (or that the guy that mentioned mistral just actually meant they're integrating with taskflow as well!) | 20:53 |
harlowja_ | could be either, ya :-P | 20:53 |
trad511 | busterswt: 3331 correct | 20:53 |
*** nati_uen_ has quit IRC | 20:53 | |
busterswt | trad511: and your physical bridge (br-ex, i guess?) has what physical interface in it? | 20:54 |
*** networkstatic is now known as networkstatic_zZ | 20:54 | |
harlowja_ | salv-orlando there was discussion with mistral folks and me at summit, hopefully we'll have a detailed plan of the mistral+taskflow alignment soon enough (although this shouldn't stop/impede neutron usage of taskflow, just more of alignment between mistral+taskflow and how we work together there) | 20:54 |
trad511 | busterswt: if my physical br-ex interface (eth5 in my case) is trunked then i'd expect either the ovs qg port to tag or some linux-fu inside the netns | 20:55 |
*** nati_uen_ has joined #openstack-neutron | 20:55 | |
salv-orlando | oh definetely. I am still at a stage where I'm studying taskflow for neutron integration. I'm sure I'll ping your team in the next few weeks with a lot of silly questions | 20:55 |
harlowja_ | salv-orlando sounds good | 20:56 |
busterswt | trad511: you should see a flow on br-ex that converts the internal ovs tag to 3111 for traffic coming from br-int. use ovs-ofctl dump-flows br-ex to see. you would see the opposite flow on br-int for traffic coming from br-ex | 20:56 |

*** a_le has quit IRC | 20:57 | |
*** nati_ueno has joined #openstack-neutron | 20:58 | |
busterswt | trad511: speaking of, in your subnet you'll want to set gateway_ip, otherwise the namespace won't have a default gateway and traffic wont get routed out | 20:58 |
busterswt | trad511: that blog had you configure a host route, which won't work in this case | 20:58 |
trad511 | busterswt: agreed, i have been running ping and tcpdump inside namespace exclusively to troubleshoot | 20:58 |
trad511 | busterswt: i have no br-ex flow that does the tagging… hava a single NORMLL action flow that looks like it's default and does nothing but pass traffic | 20:59 |

trad511 | busterswt: are you saying that the qg ifx should be on br-int? is the idea that the flow would get properly tagged w/ provider vlan and it would go to br-ex via int-br-ex/phy-br-ex? | 21:32 |

*** dfarrell07 has quit IRC | 21:36 | |
busterswt | trad511: if external_network_bridge is indeed unset, or empty, in l3_agent.ini, then that should be the behavior (qg interfaces go to br-int), You could also set it to br-int manually. did it work for the new router you created? | 21:37 |
*** nati_ueno has quit IRC | 21:37 | |
*** dfarrell17 has quit IRC | 21:39 | |
trad511 | busterswt: existing config that does the wrong thing has external_network_bridge set to br-ex. confusing that external_network_bridge would be the integration bridge… confirming in another environment i have. it's possible that this worked previously because we had pure provider nets (vms dropped directly on vlan) and never tested the router bits | 21:40 |
*** leseb_ has quit IRC | 21:42 | |
*** kbringard1 has quit IRC | 21:42 | |
*** dvorkinista has quit IRC | 21:44 | |
busterswt | trad511: well neither method is necessarily wrong, just provide a little different way of accomplishing the same thing: providing external connectivity. if you use br-int as the external bridge, then you can utilize the provider attributes of the network and OVS will tag the traffic. you could have br-ex set as the bridge and rely on the host os to tag the traffic (if a vlan interface like eth5.3111 were in there) | 21:44 |
*** mlavalle has joined #openstack-neutron | 21:44 | |
busterswt | and external_network_bridge is unique to the router bits in this case, which is prob why it never affected you | 21:45 |
trad511 | busterswt: the latter is exactly where i was headed, but what you say makes complete sense…after the fact | 21:45 |

pcm__ | carl_baldwin: The summary on the issue (and in case others' on IRC are interested), is that I'm trying to separate out the validation logic from the persistence logic in the L3 VPN code. I'm pulling out into separate function and then changing the calling so that the service driver has an opportunity to override/enhance the validation. | 22:02 |
*** otherwiseguy has joined #openstack-neutron | 22:03 | |
carl_baldwin | pcm__: Good summary. I’ll send a reply momentarily. | 22:03 |
pcm__ | carl_baldwin: Thanks! | 22:03 |
pcm__ | carl_baldwin: Just not sure if I should do this preemptively for all config actions, only for those that have validation logic, or only those that currently have override/extension needs by providers. | 22:05 |
* pcm__ Wondering if this will fall under YAGNI | 22:06 | |
trad511 | busterswt: well setting external_network_bridge = br-int did the trick (commenting it out did not). my qg now gets created on br-int and the flow retags to correct external 3331 vlan and gw and vms can reach the outside world | 22:06 |
carl_baldwin | I was actually wondering if I should say YAGNI for #3. | 22:06 |
busterswt | trad511: that's great! br-ex is the default, which is why commenting it out didn't work. you could leave the value blank though, and that should've worked as well | 22:07 |
trad511 | busterswt: so an efficiency question. is it less work for the system to go the "br-int" way or have linux tag traffic? | 22:08 |
pcm__ | carl_baldwin: Was thinking about 1B or 1C too. Seems like a lot of work for 1A and may not need used. | 22:09 |
trad511 | busterswt: ie. which would scale better w/ increased traffic - ovs flows retagging or linux dealing w/ the tagging? | 22:09 |
pcm__ | carl_baldwin: For Q2 it's just a naming preference thing. I really like validate/apply, but not sure if I'll get a lot of push back from cores. | 22:10 |
