23:42:53 gmann ok
23:43:33 mriedem ah yeah https://review.openstack.org/#/c/330406/58/nova/api/openstack/compute/schemas/migrations.py@47
23:43:43 mriedem so in 2.55 he'd now restrict to the list of known parameters
23:44:01 gmann nice.
23:44:35 gmann and all pagination param are single_param.+1
23:51:50 openstackgerrit Ed Leafe proposed openstack/nova master: Add Selection objects https://review.openstack.org/499239

23:51:53 openstackgerrit Ed Leafe proposed openstack/nova master: Make conductor pass and use host_lists https://review.openstack.org/511358
23:51:53 openstackgerrit Ed Leafe proposed openstack/nova master: Refactor the code to check for sufficient hosts https://review.openstack.org/520242
23:52:12 edleafe mriedem: ^^ refactored
23:53:38 efried jaypipes I find it very confusing that _Provider represents a node in a tree of providers, but ProviderTree actuall represents any number of such trees.
23:54:12 efried Rename ProviderTree to ProviderTrees. Or ProviderBush.
23:56:38 edleafe efried: ProviderVine?
23:57:06 efried edleafe ProvideMeVino
23:57:24 edleafe I like the way you think!
23:57:38 eandersson btw does placement take actual resources into account when scheduling vms on overcommited hosts?
23:59:04 eandersson In Mitaka we are hitting this when the compute is out of memory, but the scheduler still thinks there is room available
23:59:05 eandersson > qemu-kvm: cannot set up guest memory 'pc.ram': Cannot allocate memory
23:59:08 openstackgerrit Eric Fried proposed openstack/nova master: Iterator for a provider tree https://review.openstack.org/520243
23:59:28 efried jaypipes We're gonna need that ^
23:59:42 mriedem eandersson: are you setting the reserved space config?
23:59:51 eandersson Yea
#openstack-nova - 2017-11-16
00:00:00 eandersson This is with overcommit 1.5 on memory, which is fine in most cases for us
00:00:02 mriedem reserved_host_memory_mb
00:00:04 mriedem ^
00:00:15 eandersson The problem is that if one or two VMs are using all their memory
00:00:24 eandersson the overcommit ratio won
00:00:26 eandersson won't work
00:00:44 mriedem the reserved_host_memory_mb config option is used to tell placement that there is reserved space on a compute that can't be claimed by nova
00:00:49 mriedem and the scheduler will take that into account
00:01:30 eandersson Lets say you have 10GB memory, and 4 VMs with 5GB each and overcommit set to 2x (total 20GB)
00:02:00 eandersson or even better 12GB memory, 4 VMs with 5GB etc and reserved_host_memory_mb set to 2GB
00:02:29 eandersson If three of those VMs are actually using 10GB in total
00:02:37 eandersson The forth VM will fail to be created
00:03:32 eandersson but the scheduler will think that there is room on the VM, as it thinks the compute has 20+2GB memory
00:04:23 mriedem have you tried to recreate that in ocata?
00:04:36 mriedem otherwise i'm going to have to phone a friend (jaypipes)
00:04:53 eandersson I haven't yet
00:05:02 eandersson tbh it's not a big deal, but it's the issue causing the duplicate ips
00:05:13 eandersson (so fixing the dup ips and worst case it will reschedule)
00:05:15 mriedem ok, well, reschedules is a big deal we're trying to kill off
00:05:28 mriedem and still support reschedules with cells v2
00:05:37 mriedem so we're assuming that reschedules shouldn't happen due to failed claims
00:05:58 eandersson I'll see if I can test it in Ocata or Pike.
00:05:59 mriedem at least now that in pike with the filter scheduler we 'claim' in the scheduler rather than the compute
00:06:03 mriedem try it with pike
00:06:11 mriedem pike is the scheduler change to allocate resources in the scheduler rather than compute
00:06:15 mriedem using placement with the filter scheduler
00:06:18 eandersson Only tested it in Mitaka so far, but would motivate us to upgrade sooner :D
00:06:26 mriedem if things still don't work and yo'ure hitting reschedules, that would be very good to know
00:10:25 openstackgerrit Eric Fried proposed openstack/nova master: WIP: Use update_inventory from the resource tracker https://review.openstack.org/520246
00:10:44 efried jaypipes And here's where I'm going with it ^

01:21:49 gmann alex_xu: yea, you can use this https://blueprints.launchpad.net/nova/+spec/api-extensions-merge-queens
01:21:49 alex_xu gmann: thanks
01:21:49 gmann alex_xu: i think i created etherpad also for that, may be forgot to ping you.
01:21:49 gmann let me search

03:02:37 tonyb mriedem: Fixed my messup and I switch the Depends-On to the merged review which should be harmless
03:03:05 mriedem yeah ok
03:03:09 mriedem you going to re-approve or should i?
03:03:25 tonyb either or
