#openstack-nova - 2019-07-16
14:37:17 efried gibi: I only regret I can't send "heal port allocations" to the gate.
14:37:26 efried half a dozen +As stacked up behind that one.
14:38:05 gibi efried: no worries. we will wait for Matt to to +A that after he is back
14:38:33 gibi meanwhile I can finally refocus on the server move operations + bandwidth series

15:22:35 artom That was fast
15:23:28 sean-k-mooney it took longer then i planned but i think ^ is right
15:25:02 sean-k-mooney i guess not
15:26:15 sean-k-mooney oh i think im missing a new line
15:27:22 sean-k-mooney and a space
15:27:52 openstackgerrit sean mooney proposed openstack/nova stable/stein: [DNM] testing bug/1813789 revert resize events https://review.opendev.org/671079
15:34:48 sean-k-mooney ok zull accpeted that so it should report back eventually
16:34:19 efried shilpasd: still around?

16:35:59 efried shilpasd: I'm going to edit the commit message of https://review.opendev.org/#/c/671075 real quick so I can be +2 on the whole series.

16:38:20 efried dansmith: I'm +2 all the way up on the forbidden aggs series ^
16:40:01 efried the biggish final patch is mostly doc
16:44:07 openstackgerrit Raubvogel proposed openstack/nova master: Author: Mauricio Tavares https://review.opendev.org/671106

17:20:06 efried sean-k-mooney: you around?
17:20:49 sean-k-mooney kind of
17:20:54 efried I try and I try, but I just can't follow this stuff. Would you please review https://review.opendev.org/#/c/670588/ for me? I'll proxy your +1.
17:21:06 sean-k-mooney im wait on food to be delivered in 20 mins or so
17:21:18 efried I think it was your suggestion anyway from the subsequent patch
17:21:54 sean-k-mooney oh right. in the non ovs case we added a noop pluging to os vif to handel generic vhost-user plugging
17:22:07 sean-k-mooney and for the ovs case its already handeled by os-vif
17:23:09 efried yeah, see, I can read those words, but I've never been able to follow the code around that area
17:23:11 sean-k-mooney so those functions should never get called. but ill trace through the code and confim
17:23:16 efried thanks
17:24:27 sean-k-mooney well it used to do an indrect function call by appending the vif type to a prefix and using gettr to look up the function
17:24:39 sean-k-mooney so it was not exactly the simplest code
17:25:27 sean-k-mooney that actully predates me working on openstack but i never really understood why we did it that way
17:25:30 efried yeah, the getattr removal is in the subsequent patch, and I was able to follow that. But it's also dependent on this being right.
17:26:20 sean-k-mooney this code path is for netwroking-vpp or snabb switch
17:26:41 sean-k-mooney its very very rarly used but we still dont want to break people that use it
17:37:07 openstackgerrit Merged openstack/nova master: Defaults missing group_policy to 'none' https://review.opendev.org/657796
17:53:27 sean-k-mooney efried: done. i have put a walk through of how the dead code would have been called in the past but it is never used after https://review.opendev.org/#/q/Ifab3006454708ab290b93f02d82b794c334c3946 was merged last cycle
17:53:44 efried thanks sean-k-mooney
17:54:31 sean-k-mooney no worries dinner just arrived so ill be away for a while. i might be back in an hour or two
18:01:06 spatel sean-k-mooney: yt?
18:01:49 spatel virsh list command showing instance-<uuid> is there anyway it can show hostname of instance
18:03:29 spatel In google people saying "virsh domhostname <domain>" but what is domain going to be?
18:03:51 spatel also i don't think kvm support that
18:20:18 donnyd Was there still interest in the NUMA for fortnebula?
18:20:49 donnyd LOL... interest in NUMA topologies
18:21:35 donnyd I have things to a more stable state with decent performance, so now I can move forward
18:25:31 openstackgerrit Mauricio Tavares proposed openstack/nova master: Increases the level of detail provided by the debug messages in pci_passthrough_filter.py. https://review.opendev.org/671106
18:30:41 efried artom, sean-k-mooney: ---^ ?
18:39:58 artom donnyd, yes please, I would like 1 the NUMA ;)
18:40:24 donnyd LOL +2
18:40:27 artom For serious though, yeah, flavors with >= 2 NUMA nodes would be awesome
18:40:34 donnyd you get 2 numas artom
18:41:26 donnyd I am not deep in the zuul or nodepool code, so how does the test work. Can you ask for a specific flavor?
18:41:53 donnyd I need a way to stay compatible with the other jobs
18:41:59 artom efried, I don't even know where to start with that. I guess look at the logic before drowning them with the formatting and whitespace nits?
18:42:24 artom donnyd, that's not my strong suite, I'm afraid
18:42:55 efried artom: I was pointing at donnyd, not at Mauricio's patch
18:43:06 artom efried, oh, hah
18:43:38 efried my ---^ was an attempt to go around the corner
18:44:16 artom donnyd, sean-k-mooney would most likely know, though I hate to pile even more things on this plate
18:44:31 artom Or ask in -infra? Is that good advice?
18:46:39 donnyd 2:44 PM <clarkb> there isnt
18:46:39 donnyd 2:44 PM <clarkb> we can do provider specific flavors but generally avoid that to handle cloud outages
19:04:21 donnyd artom: I will have to learn how to setup NUMA aware flavors, (unless someone knows off the top of their head) and it looks like we have a path forward
19:05:59 artom donnyd, it's kinda tedious, but not super hard: https://docs.openstack.org/nova/latest/user/flavors.html
19:06:05 artom Scroll down to CPU topology
19:06:24 artom Sorry, NUMA topology
19:06:34 donnyd Ok, I will take a look
19:07:08 artom Actually both
19:07:58 artom hw:cpu_ controls the guest topology, hw:numa_ controls how it maps onto host hardware
19:11:30 openstackgerrit Merged openstack/nova master: Use Adapter global_request_id kwarg https://review.opendev.org/670907
19:58:44 prometheanfire is one of the use cases for nova to run 1-3 compute nodes in 3-4 DCs across the world? (via host aggregates and AZs)
19:59:02 openstackgerrit Eric Fried proposed openstack/nova master: Nova object changes for forbidden aggregates request filter https://review.opendev.org/671072
19:59:02 openstackgerrit Eric Fried proposed openstack/nova master: DB API changes to get non-matching aggregates from metadata https://review.opendev.org/671074

20:00:10 efried prometheanfire: What's this in reference to?
20:00:53 prometheanfire sometihng I may be doing soon
20:01:09 prometheanfire cross continental rabbit could be fun
20:01:34 prometheanfire just not sure if it's an intended (supported) use case for nova
20:03:34 openstackgerrit Merged openstack/nova master: vif: Remove 'plug_vhostuser', 'unplug_vhostuser' https://review.opendev.org/670588
20:06:09 efried ohh, okay. So you're asking if you can make a setup like that?
20:06:22 efried prometheanfire: in a single cell?
20:06:39 efried Cause I would imagine you can surely do a multi-cell that way
20:06:50 efried donnyd: do you know about this?
20:07:19 prometheanfire ya, could do it multi-cell I suppose, single cell may be nice management wise though
20:07:48 efried prometheanfire: isn't that how zuul is set up?
