#openstack-nova - 2018-09-27
19:15:00 mriedem *can also
19:15:14 imacdonn I always thought that was weird .. that you can't do that (but can for live)
19:15:44 imacdonn (always => since icehouse days, at least)
19:16:06 cfriesen imacdonn: artificial OSC limitation
19:16:34 cfriesen imacdonn: the compute API lets you specify a host since 2.56
19:16:34 imacdonn hmm
19:17:20 cfriesen (which is admittedly fairly new)
19:17:37 imacdonn right .. I was just checking ;)
19:18:16 imacdonn so "the struggle was real" when I last looked
19:18:28 artom I'm guessing splitting live and cold migration into different subcommands is no longer an option at this point, right?
19:18:37 artom Since they're, you know, fundamentally different operations?
19:19:20 cfriesen artom: to the end user, they're very similar.
19:19:36 artom cfriesen, you mean besides the fact that your workload goes down?
19:19:37 artom ;)
19:20:06 artom And that live migration is admin-only (by default)?
19:21:12 cfriesen artom: cold is too, isn't it?
19:22:02 artom cfriesen, doh, you're right
19:22:21 imacdonn to a typical sysadmin (I'm thinking private cloud), "migrate" means "VM is running on node A, and I want it to be running <somewhere else>" .. if we can do it without shutting the VM OS down, that'll make my life better
19:22:29 artom Wait no, I was looking at the wrong bit of api-ref
19:22:42 imacdonn from that perspective, they're basically the same thing
19:22:44 artom ... aaand no, still admin-only
19:23:41 artom I dunno, there's just a whole bunch of things that cold migration can do that live migration can't
19:24:20 artom And anyways, I was being rhetorical, we're obviously not going to limit osc migrate to cold migration and add a new osc live-migrate at this point.
19:27:27 mriedem cold migrate is admin only, resize is non-admin
19:27:32 mriedem w/ cold migrate under the covers
19:27:46 artom Kinky.
19:28:02 mriedem only on anniversaries dude
19:28:13 mriedem resize and cold migrate have been married awhile
19:28:59 artom Yeah, I'm surprised there's still anything going on under the covers.
19:29:08 imacdonn better than cold feet
20:07:24 mriedem melwitt: i think the vmware live migration change can go into a runway slot
20:07:34 mriedem rgerganov updated it to get ci passing,
20:07:41 mriedem i've done another pass, still -1 but it's closer
20:08:24 melwitt ok, cool. I'll add it then. missed the +1 vote from the vmware CI earlier today after I rechecked it
20:49:57 melwitt nova meeting in 11 minutes
20:50:06 melwitt 10 minutes
20:52:36 mriedem melwitt: want to hit this backport? https://review.openstack.org/#/c/605260/ - would be good to get those reverts in stable merged/released since they regressed blazar
20:52:50 mriedem the fix to replace the original is stacked on top on master but the gate is....not cooperating
20:53:53 melwitt can do. any idea why lee removed his vote?
20:57:36 mriedem no idea
20:57:38 mriedem classic lee
22:45:56 cfriesen is there an equivalent of CONF.reserved_huge_pages but for regular memory? (per numa node though)
22:46:58 cfriesen I can see CONF.reserved_host_memory_mb but that's not specifically 4k pages and is per compute node, not numa node.
22:47:44 openstackgerrit Matt Riedemann proposed openstack/nova stable/pike: Update RequestSpec.flavor on resize_revert https://review.openstack.org/605879
23:01:11 openstackgerrit Matt Riedemann proposed openstack/nova stable/ocata: Update RequestSpec.flavor on resize_revert https://review.openstack.org/605880
23:03:36 mriedem stable branch core review please https://review.openstack.org/#/c/600113/
23:08:45 cfriesen mriedem: what would you think of something like CONF.reserved_huge_pages but for regular memory? (ie, to reserve specific amounts of 4K memory on each host numa node)
23:10:35 cfriesen or can CONF.reserved_huge_pages be used for 4k pages as well even though the name implies otherwise
23:11:14 mriedem cfriesen: i don't think you realize that i don't know anything about that nova/virt/hardware stuff
23:11:22 cfriesen heh
23:11:34 cfriesen I'm off to go dig through code
23:11:43 mriedem so not reserved_host_ram or whatever we have?
23:11:48 mriedem that goes on the compute node?
23:12:20 cfriesen yeah, "reserved_host_memory_mb" is per compute node
23:12:25 mriedem reserved_host_memory_mb
23:12:35 mriedem and you want something to reserve ram per numa node?
23:13:27 openstackgerrit Matt Riedemann proposed openstack/nova stable/ocata: Fix instance evacuation with PCI devices https://review.openstack.org/605881
23:13:37 mriedem melwitt: fyi i'm trying to flush through my stable queens and pike changes which also apply to ocata, and then gonna probably send a thing to the ML to wrassle a stable branch review sprint for next week
23:13:49 mriedem to flush all stable branches so we can get ocata released and tagged for EM
23:14:17 mriedem it took an entire week to just get stuff merged for the last round of stable releases
23:14:19 mriedem b/c of the gate
23:16:19 cfriesen mriedem: after looking at the code, I think I could use CONF.reserved_huge_pages to reserve 4K memory per numa node, even though it's not actually huge pages. now to actually try it out
23:17:28 melwitt mriedem: sounds good
23:20:56 openstackgerrit Matt Riedemann proposed openstack/nova stable/ocata: Update nova network info when doing rebuild for evacuate operation https://review.openstack.org/605882
