mesteryIt's super easy to reproduce, I have a hacked Vagrant which sets up both comptue nodes for live migration14:00
Sam-I-Ammestery: did you see where ovn thinks your mac is?14:02
mesterySam-I-Am: Looking at that next, pushing the vagrant review now.14:02

Sam-I-Amfine by me17:37

russellbright but we don't support that17:44
russellbwell, we don't suppor vxlan at all17:44
Sam-I-Ambecause you cant stuff md into it, right?17:44

russellbcool :)19:41
Sam-I-Amrussellb: we really need to solve some of this mtu problem soon19:45
Sam-I-Ami'm trying to find time, but its scarce in light of other things19:45
Sam-I-Ami have a feeling we'll do our own thing until neutron figures itself out19:46
russellbwe never seem to have enough time, yet we all have all the time there is19:46
* russellb gets deep19:46
Sam-I-Amright now the neutron mtu stuff is really only in ML219:46
Sam-I-Amwell, some of it19:46
Sam-I-Amwe can re-use advertise_mtu for now because we use the dhcp agent19:48
Sam-I-Amall of the existing mtu stuff is broken and misleading19:48
Sam-I-Amwhich is why my option for our ini file is 'physical_network_mtu'19:48
Sam-I-Am1 option, provides the basis for everything mtu19:48

regXboirussellb: I'm thinking of breaking the incremental processing patch I have into three parts20:01
regXboi(1) add code to ovn end to end tests to help debug things going wrong20:01

regXboiyep... first two parts will be on there way shortly20:13
russellbregXboi: can you re-send those 3 patches to me directly, as well?20:13
russellbrussell@ovn.org20:13
russellbi'm losing about half of ovs mailing list mail right now ...20:14
regXboirussellb: I tried with the first one separately... hopefully it will work, but it might look like it has come from an odd place20:15
regXboiI'll be sure to add you to the cc list of the second patch20:15
russellboh ok20:15
russellbi did get the first one20:15
russellbthought i lost the other 220:15
Sam-I-Amrussellb: this mtu stuff is proving to be more difficult than i thought20:28
Sam-I-Ami just dont understand neutron well enough :/20:29
Sam-I-Ami know what i want to do, just not really how to get there20:29

*** jckasper has quit IRC20:31

regXboiI wasn't going to hold the ones that are clean and independent on the one I'm still working20:31
russellbok.20:31
regXboiand since I'm doing a split, I want to make sure I get it all correct20:31
regXboior as much as I can20:32
russellbok, it's just confusing to send an emaiil that says "1/3" but there's no 2 or 320:34
russellbbest to just wait until you're ready to post them all20:34
* regXboi marches to the beat of a different drummer sometimes20:34
regXboiactually, I was torn as to whether to call them 1/3 and 2/3 because they really are independent20:35
