SamYaplesdake: i am here04:13
SamYapleCBR09: there are no ubuntu-binary images04:13
SamYaplesdake: you around?04:13
CBR09yes, i saw. So, would ubuntu-source work?04:17
SamYaplein liberty-2, im not so sure. there has been quite a bit of change since then04:18
SamYapleyea none of the ubuntu images exist in liberty-204:19
SamYaplewell very few04:19
SamYaplei didn't implement them until liberty-3 i believe04:19
SamYaplerc-1 is today, i would suggest running that when that tag actually gets snapped04:19
SamYaplethere wont be reliable built images until liberty stable is released04:20
CBR09https://openstack.nimeyo.com/57563/openstack-announce-announcing-release-liberty-milestone04:21
CBR09I see ubuntu-source was supported04:21
SamYaplethats liberty-304:22
CBR09I'll be give liberty-3 try, with ubuntu-source04:23
CBR09hope it work04:23
SamYaplethere are no built images for it, but it was working when the tag was snapped yes04:24
CBR09I see build.py tool04:25
CBR09./build.py -b ubuntu -t source04:26
SamYaplethat will build the ubuntu images yes04:27
SamYapleif you need to use a private registry dont forget to change the namespace04:27
CBR09yes, thanks you,do you know: has anyone try build ubuntu-binary in liberty-3?, and is it work?04:30
SamYaplei use ubuntu exclusively, but i haven't gone back and rebuilt liberty-3 since it was initially snapped, no04:31
SamYapleit worked at the time but as packages change upstream its not always possible to rebuild old versions04:32
SamYaplebut thats just common infrastructure stuff04:32
SamYaplenothing specific to kolla04:32
CBR09yes04:38

inc0morning06:51
inc0sdake, around?06:51
SamYaplemorning inc006:54
inc0hey Sam, do you know if Steven pushed RC1 release?06:54
SamYapledoubtful06:57
inc0I'd hate to see logging bp fail to merge due to swift :/06:57
inc0and only swift rly06:58
SamYaplejust push up your changes06:59
SamYaplei ceph needs to merge too06:59
inc0hasn't it been merged?06:59
SamYaplenot the stuff that actually makes openstack work with ceph06:59
SamYaplejust the ceph cluster building07:00
inc0ah this one, got it07:02
inc0SamYaple, any reason to configure LM flags when ceph is enabled?07:06
SamYaplereference?07:07
inc0https://review.openstack.org/#/c/225933/10/ansible/roles/nova/templates/nova.conf.j207:07
SamYapleoh yea. no thats not a requirement. Honestly i forgot that was there and when i saw its just too late to pull apart that patch07:08
SamYaplesince it needs to merge yesterday07:08
SamYapletheres no reason _not_ to enable live migrate07:08
inc0well, I could name a few, but yeah, I don't have problem with having it there07:08
inc0just was curious if there was any connection to ceph07:09
SamYaplecan you actually name a few? im curious07:09
SamYapleand thats not whats enabling live migration, thats just the proper live migrate flags07:09
inc0it can kill your CPU and manangement network07:09
SamYaplelive-migration is always enabled in openstack07:09
SamYapleits libvirt that can break if you try it and its not configured07:10
inc0tunneled is arguable07:10
SamYaplethose come from the Ceph docs07:10
inc0it's default I guess, but still arguable07:10
SamYapleyou can control it through policy.json07:10
inc0https://www.youtube.com/watch?v=Vy8rS_5vea4 have fun;)07:11
inc0you might recognize guy on the left;)07:11
SamYaplecant see the tiny screen07:12
SamYaplebut i recognize teh voice07:12
SamYaplethats ryan i think!07:12
inc0well...almost07:13
SamYaple;)07:13
inc0but I would advise you to see doctor07:13
inc0if you confuse polish accent with native us one, that's something wrong with either hearing or cerebeal cortex;)07:14
*** openstackgerrit has quit IRC07:16
inc0anyway, I think we did good job out there, and people liked this talk as well - let me know what you think07:16
inc0:O07:16
inc0gerrit has died!07:16
SamYaplepff yea07:16
*** openstackgerrit has joined #kolla07:16
SamYaplescrew gerrit07:16
inc0here, grab a +1 with a comment07:19
*** achanda has joined #kolla07:19
SamYaplehave you looked at the forward live migration?07:20
SamYaplethats pretty slick07:20
inc0you mean post-copy?07:20
SamYapleyea07:20
inc0yeah, we mentioned it there07:20
inc0it's cool07:20
SamYapleyou can configure which network openstack uses for livemigration07:21
inc0but it'll affect performance in vm and if something fails during LM everything breaks07:21
SamYapleyea agreed07:21
inc0it's hacky, also mentioned there;)07:21
SamYaplei believe you :) and its not so hacky07:21
SamYapleif you do routes you can do it outside of openstack pretty cleanly07:21
SamYapleall your compute nodes communicate over a different nic, same network07:22
inc0well, we shown way how to do it using url07:22
SamYapleyea thats the openstack config way07:22
inc0so just lm then has separate network07:22
inc0but that's hacky and require tunneled07:22
inc0and tunelled kills cpu07:23
inc0it's all tradeofs07:23
SamYaplesure. but you can do routes to ensure the traffic goes over the nic you want07:23
SamYapleyea07:23
inc0I didn't thought about routes there but yeah, that would work07:23
SamYaplethats how i do it here with my nics07:23
inc0I don't think there is any other cn->cn communication in nova07:24
SamYaplenope07:24
inc0not sure if other stuff wouldn't fall for it too07:24
inc0for example ceph if you'd like to have OSDs on CN07:24
SamYapleany traffic going to another compute would yes07:24
SamYaplebut thats fine07:24
SamYaplesince thats where it was going anyway07:25
inc0yeah07:25
*** CBR09 has quit IRC07:25
SamYaplewell hold on, any traffic on the same _network_ going to another compute07:25
inc0anyway, we want to make bp to make it properly07:25
SamYaplehe. yea i did that before just append -lm to the hostname07:27
SamYaplei used other things,but yea07:27
SamYaplehttps://github.com/SamYaple/openstack_libvirt_deploy/blob/master/httpd/preseed/bootstrap.sh#L14707:28
inc0it works07:29
SamYapleyup07:29
SamYaplesetting the route was cleaner for me07:29
SamYaplebut both have thier merrits07:29
inc0and both are kinda hacky07:29
SamYaplei dont find the route hacky at all07:30
SamYaplebut i like networking07:30
inc0route thing would work without tunneled, and that's huge plus07:30
SamYaplecan you explain why TUNNELED is needed otherwise?07:30
SamYapleim a bit fuzzy on that point07:30
inc0uri is libvirt conf07:31
inc0and if you won't use tunneled, connection is between qemu's07:31
inc0somehow they ignore uri07:31
SamYaplehmm yea i see07:32
inc0but it's way better perofrmance07:32
SamYaplessh is going to be hard/impossible with kolla07:32
inc0you'd need keys in nova-libvirt07:33
inc0and sshd07:33
inc0so yeah07:33
inc0or...hmm07:33
SamYaplewell i mean you _could_ do it if you did some other thing07:33
inc0won't it try normal sshd?07:33
SamYaplebut its hacky hacky hacky07:33
SamYapleyea you can get it to work, but shared backend is better :)07:34
inc0uhh07:34
inc0anyway, that might become an issue at some point07:34
inc0people want's security out there07:34
inc0want*07:34
SamYapleconsidering all the storage traffic in unencrypted i don't see the benefit07:35
inc0that's another issue;)07:37
SamYaplenah ill just secure my network properly and take the perforamnce benefit07:38

mandreSamYaple, you always have the hairiest patches13:12
mandrealways take a while to review13:13
mandrenot even talking about testing...13:13
SamYaplemandre: sorry13:13
SamYaplein this case i dont know how else to add it13:13
SamYapleits large :/13:13
mandre;)13:13
SamYaplemy goal is to make it non-impacting to the existing code and then just have bug fixes that are smaler if needed :)13:14
mandreit's fine13:14
mandreat least it's not 700 1 liner patches13:14
SamYapleyea sdake13:15
mandreafter looking at my review you'll probably realize I know zip in ansible or ceph13:15
SamYaplemandre: would you consider merging that patch as is if i submit a bug fix patch right now?13:19
SamYaplewe can bug fix after rc-1 but i cant afford ceph not ot make it13:19
*** dimsum__ has quit IRC13:20
mandresure, has anyone else than you tested ceph works?13:22
openstackgerritSam Yaple proposed openstack/kolla: Ceph bugfix for missing host  https://review.openstack.org/22818513:22
SamYapleinc0 was yesterday13:22
SamYapledont know the progress13:22
SamYapleim more focused on "does it break anything else in kolla" than does ceph work13:22
SamYaplethat said i have tested and demoed ceph on virtual and physical hardware several times at this point13:23
SamYapleand it is just a port of the yaodu code which is 6 months old, so its more tested than most stuff we merge13:23
mandreyeah, i figured13:25
SamYapleive got some docs brewing as well13:26
mandreshould be gating now13:27
mandregood job SamYaple13:28
