dlevyHaving some issues with the Vagrant environments. When booting the cirros VM on a newly created network, the cirros VM interface is not configured. Anyone else seeing this?18:26
rtheisdlevy: I deployed an environment this morning and booting on the private network was successful18:28
rtheisdlevy: what type of network did you create?18:29
dlevyI created a regular network through openstack, with a single router/interface/subnet18:31

rtheisdlevy: I just created a private network and booted a couple cirros VMs successfully in my environment.18:42
*** aginwala has joined #openstack-neutron-ovn18:43
dlevyThey are able to ping each other?18:43
rtheisdlevy: I was able to ssh from one to the other18:44
dlevyI'll give it another go. The steps I took (all from openstak)18:45
dlevy1. Create network, create router, create subnet and attach to router, add interface to router with new subnet18:45
rtheisdlevy: I just created a network and subnet... no router18:46
dlevyK, will give it a go, thanks18:47

dlevy1 more question for the day :) I'm trying to trace through the openflow table for better understanding, using a VM I booted on the private network 'sudo ovs-appctl ofproto/trace br-int ip,nw_src=172.16.1.4 -generate' like this. I end up with a no-match found. If I could get an example working, I'll be able to run investigate it more on my own. Thanks for any help19:07

regXboirussellb: you back and willing to talk your L2 GW?20:07
russellbi am back and just got off the phone20:07
russellbso i'm free20:07
russellbwhat's up20:07
regXboiso... indulge me on this one20:08
regXboibut the L2 GW is pretty much the old, non-HA neutron "router" without sNAT20:08
regXboiThen, if I hook in the still be worked on N/S nat stuff, I have the pre-HA neutron router20:09
russellbit's not L3 aware at all20:09
regXboinow... one thing that I don't know is OVN's opinion/approach to SFC20:09
russellbthere's not really a neutron equivalent of this20:09
regXboilike i said, indulge me for a bit :)20:10
russellboh, ok20:10
russellbi should wait for a question then i guess :)20:10
regXboiok... so, mestery and I have been talking, and we think that the following would function as the equivalent of what the neutron L3 is doing currently:20:11
*** aginwala has joined #openstack-neutron-ovn20:11
mesterylol20:11
regXboiyour sw L2 code + NAT patches + BGP speaker/listener20:12
regXboier + HA solution20:12
regXboiand the interesting thing would be to have a few hooks for SFC as well20:12
*** ramu_ramamurthy has quit IRC20:13
regXboiwhile reviewing the patch, it dawned on me that it could more of a clustering approach to HA20:13
regXboiin the sense that I define the bridge mapping on multiple chassis, have those chassis select the "primary" gateway20:13
regXboiand then have a packet to the gateway replicated and carried to all gateways, and only emitted by the primary20:14
regXboiif the primary's chassis were to die, the remaining chassis select a new primary, and so forth and so on20:14
regXboiis this making any sense?20:14
russellbI haven't really thought about HA for this20:15
russellbyou could make this HA completely outside of OVN20:15
regXboiwell, I could20:15
regXboibut I'd rather not if I don't have to20:16
russellb:)20:16
russellbi'm probably more interested in fleshing things out to where we have L3 first20:16
russellbto make sure we're addressing HA in the right place20:16
russellbbut what you said does make some sense20:17
regXboirussellb: well, I'm sure that mestery will volunteer somebody for helping with that :)20:17
russellbThe IBM OVN army20:17
*** azbiswas has quit IRC20:20
regXboiwell, to get to L3, I *think* all I need is sw L2 GW + nat20:26
regXboithe BGP and SFC adds are to make adding *aaS and real routing easier20:27

tongliovs>=2.4.0;python_version=='2.7' # Apache-2.020:31
tongliis it a mistake?20:31
tonglipip install -r requirements.txt just fail over.20:31

russellbtongli: what's wrong with it?20:38
russellbyour 'pip' might be too old20:38
tonglipip is 1.6.x20:39
*** aginwala has joined #openstack-neutron-ovn20:40
tongliso that is the right syntax, we need to specify python_version to be exact 2.7?20:40
tongli@russellb, I did not find similar syntax from other project, just wondering if that was ok. Since my pip install -r requirements.txt fails.20:44
russellbthat is correct syntax20:46
russellbhttp://git.openstack.org/cgit/openstack/requirements/tree/global-requirements.txt20:46
tongliconditional requirements. hmmm. ok. thanks.20:46
tonglithanks @russellb.20:47
