thorstesberglu: Did you get the instructions on how to spread out the scheduling?13:38
esbergluthorst: Yeah. The templates are failing to build. They can’t fetch the flavors list13:40
esbergluOpenStackCloudException: Error fetching flavor list (Inner Exception: Unable to establish connection to http://9.114.251.95:8774/v2.1/flavors/detail?is_public=None)13:40
thorstblah13:42
thorstcan you manually do a deploy?13:42
thorstfrom openstack itself?13:42
esbergluHmm. There is only a public network. Usually there is a private right?13:44
thorstlet me hop on and take a peak13:44
thorstesberglu: so, everything looks fine except one thing.13:46
thorstesberglu: one other thing, don't put IPs in the IRC generally  :-)13:46
thorstat least ones behind the firewall13:46
esbergluYeah I realized that right after I hit enter13:46
thorstheh13:47
thorstso one thing that seems weird to me is that the template is active13:47
thorstbut there are TWO subnets on this thing13:47
esbergluThat other one must get created during the stack. I thought we cleared those all out though13:49
*** smatzek has joined #openstack-powervm13:50
thorstright.  So why is the 'public-subnet' there13:53
esbergluOkay I deleted that13:54
thorstand more importantly, why is it there on the network that we created13:54
esbergluShouldn’t that not be possible? Don’t you have to specify a network to create a subnet?13:58
*** apearson has joined #openstack-powervm14:05
thorstesberglu: correct14:06
thorstthat's what is weird14:06
thorstdid our playbook do it?14:06
esbergluI don’t think so. There haven’t been any changes involving that14:08
*** arnoldje has joined #openstack-powervm14:12
*** tjakobs has joined #openstack-powervm14:21
thorstesberglu: things still failing or going through now?14:28
thorstesberglu: looks to me like it'll still fail14:30
thorstthe network is still screwed up14:31
thorstits using vlan 1052 (from the original network) and it should be using 223014:31
thorst(or maybe VLAN 1...let me verify)14:31
efriedthorst, svenkat: for remote restart and its ilk, we certainly want to enforce that the destination get vNICs on the same physnets; but do we want to enforce that the destination VM have the same redundancy level?14:32
thorstesberglu: yeah, it should have been created with VLAN 1...(not 2230)14:32
efriedI will posit that we should use whatever redundancy level is configured on the target, not try to match up with what was on the source.14:32
*** catintheroof has joined #openstack-powervm14:32
thorstefried: not sure...I think the interesting question is first around live migration14:32
thorstthen remote rebuild14:32
efriedSame question, really.14:33
thorstwell...slightly different14:33
thorstI want to know if live migration requires it14:33
thorstthat's more a seroyer question though14:33
esbergluthorst: Should I just wipe the whole network and recreate?14:34
thorstesberglu: Yeah...14:34
thorstesberglu: and when we recreate next time, keep an eye on what's going on here...14:34
*** efried has quit IRC14:36
seroyerefried, thorst, That’s a complex question…  Totally depends on the customer mindset for whether we need to protect them from themselves or not.  Legacy LPM is *very* conservative (would ensure same level of redundancy on the target as on the source).  We have options here…14:36
thorstseroyer: just exploring the art of possible14:36
*** burgerk has joined #openstack-powervm14:37
seroyerWith vNIC failover, we can more or less transparently increase/decrease redundancy level across LPM.14:37
thorstseroyer: but we'd have the ability to specify 'use these ports' like we have with NPIV migration?14:38
seroyerYes.  If you don’t specify, then you must have port labels configured.  We’ll try to match port labels.14:38
thorstwe will want to make sure that we specify that on the LPM I think...14:39
seroyerthorst, by default, if you don’t specify, we will try to match the redundancy level and pick ports by label.  If you have multiple ports with the same label, we’ll just pick (assume they are interchangeable).14:40
thorstagree...fundamentally...but will it do the splicing of trying to get them across different VIOSes, and cards and ???14:42
thorstno matter what, we need that logic in OpenStack...for cold migration or rebuild14:42
seroyerAcross VIOSes, yes.  Cards, maybe, but I think so.14:42
seroyerIf you are using 2 VIOS on the source, you need 2 VIOS on the target (generally applicable for all I/O types with LPM, occasionally there are overrides, though)14:43
seroyerWe have to be careful about maintaining compatibility with HMC, though.  (Don’t care for OVS/LB, but do for VIOS hosted networking).14:44
thorstagree...ashok should probably be involved in the API discussion?14:46
