gibislaweq: hi! would the neutron team like to have a crossproject session with nova during the PTG? From nova side we only see weak topics, like routed net support in nova and neutron port numa affinity09:45
slaweqgibi, thx for asking09:48
slaweqso far we don't even have many topics in the etherpad proposed09:48
slaweqso I don't know really if Neutron team has such need09:49
slaweqbut maybe ralonsoh, lajoskatona or rubasov will have some topics to discuss with Nova09:49
gibicool. we don't have to decide now as still plenty of weeks til the PTG09:50
gibijust wanted to raise the opportunity09:50
lajoskatonaslaweq, gibi: nothing in my head now09:50
slaweqgibi: sure, thx for asking09:51
slaweqand I think that if there are some topics from Nova's side, we can definitely schedule some common session09:51
gibiI will ask again where we are closer to the PTG09:51
gibislaweq: Wednesday would be good for Neutron?09:52
gibi28th of Oct09:52
ralonsohgibi, I'll ask sean-k-mooney about the NUMA affinity feature09:58
ralonsohif we need to have a cross project meeting during the PTG09:58
gibiralonsoh: yeah, sean-k-mooney mentioned that during the nova meeting yesterday09:58
gibiso if you two can figure things out that is cool to me too09:59
ralonsohgibi, so then yes, could be interesting of course09:59
gibiOK, noted,09:59
ralonsohand also update the status of the code now09:59
gibisean-k-mooney mentioned that it is basically done on the neutron side09:59
ralonsohgibi, almost done09:59
ralonsohone patch left09:59
gibicool10:00
gibithen it is time for nova to start planning how to use that10:00
*** rcernin has quit IRC10:09
slaweqgibi: yes, we don't have any other schedule so far so it's good for sure :)10:10
*** vinay_m has joined #openstack-neutron10:11
gibislaweq: cool, then I tentatively schedule slot from 14:00 UTC10:11
slaweqgibi: sounds good, thx10:12
ralonsohperfect for me too10:13
rubasovslaweq, gibi: Thanks, but I don't have a topic for the x-project session this time.10:18
gibiack10:18
sean-k-mooneygibi: ya i likely will end up writing a sepc to consome it in the next week or two10:19
sean-k-mooneyto cover what is require in the nova side10:20
gibisean-k-mooney: cool, thanks10:20
sean-k-mooneyfor sriov ports most of the code is already there. for numa aware vswitches i need to add one more filed to the nova vif object to store the affinity policy but im hoping the nova change will be relitivly small.10:22

kklimondaI seem to be hitting some scaling limit on ovn-based deployment - I have 9 chassis (5 computes, 4 "network") and all were configured with `external-ids:ovn-cms-options=enable-chassis-as-gw`. We've created ~850 routers and networks, plugged all routers into a shared external network,  spawned some VMs and attached FIPs to them - I can see in tcpdump that for icmp returning packets from vms are dropped by ovs-vswitchd with errors11:01

kklimondaI'm assuming it's just too many routers for such a small deployment (as that turns into 4k+ chassis)11:02
