#openstack-nova - 2018-09-13
21:26:50 efried today you might get back BW:300 from a single provider, which is :(
21:26:59 openstackgerrit Lee Yarwood proposed openstack/nova stable/ocata: [Stable Only] Remove soft-deleted instances from quota_usages https://review.openstack.org/570653
21:30:14 gibi efried: true
21:31:13 bauzas gibi: efried: that's the exact problem I hit for VGPU affinity, right?
21:31:30 bauzas if I want to have this NUMA node and that VGPU to be on the same tree
21:31:44 efried bauzas: It's less of a problem for VGPU, which is single unit
21:31:51 efried bauzas: Oh, no, that's a separate problem.
21:32:19 bauzas sorry, I learnt German and English at college, not Placement :p
21:53:13 openstackgerrit Sylvain Bauza proposed openstack/nova-specs master: Re-proposes multiple vGPU types in libvirt https://review.openstack.org/602474
21:53:59 bauzas oh, we're not advertising on nova-specs changes ?
21:54:22 bauzas I mean, I don't openstackgerrit telling my spec
21:55:43 openstackgerrit Sylvain Bauza proposed openstack/nova-specs master: Re-proposes multiple vGPU types in libvirt https://review.openstack.org/602474
21:56:54 bauzas mmm, strange but ok
21:58:34 openstackgerrit sean mooney proposed openstack/os-vif master: add support for generic tap device plug https://review.openstack.org/602384
21:59:06 bauzas mriedem: given what we said yesterday, shall we put a procedural -2 on https://review.openstack.org/#/c/599208/ and say we can't do it until https://review.openstack.org/#/q/topic:use-nested-allocation-candidates+(status:open+OR+status:merged) is merged ?
22:01:04 mriedem because once the vgpu is on the child provider, vgpu scheduling would be broken?
22:03:42 bauzas mriedem: yup
22:04:00 bauzas no valid hosts
22:04:15 bauzas since it wouldn't find any RP that fulfills the VGPU resource class
22:04:25 mriedem bauzas: i guess? alternatively, we should have a functional test that does the reshape and then tries to schedule to the vgpu in the child - which we said we wanted as part of the checklist for placement extraction
22:04:44 bauzas mriedem: yeah, I discussed that with gibi
22:04:55 bauzas mriedem: the functional test should see that
22:04:56 mriedem we do have functional tests for reshaper with the fake virt driver,
22:05:02 mriedem we just don't try to schedule to that host after the reshape
22:05:08 openstackgerrit Merged openstack/nova stable/rocky: Add functional test for affinity with multiple cells https://review.openstack.org/599731
22:05:17 bauzas mriedem: cool, I know what to do for next week
22:05:52 mriedem the functional test for reshaper mocks out the reshape code in the test itself; i suggested to efried that we move that to a fake virt driver - and if we did that, then i think we can just bolt the post-reshape scheduler request onto the same test
22:06:18 mriedem maybe we don't need to move that into a fake virt driver, idk
22:06:29 mriedem but would be nice if we can just add a few lines to that existing test to see if this passes or fails
22:07:24 bauzas mriedem: lemme test that
22:07:51 mriedem bauzas: https://github.com/openstack/nova/blob/0ba34a818414823eda5e693dc2127a534410b5df/nova/tests/functional/test_servers.py#L1835
22:08:16 mriedem yeah so at the end, just try to create an instance on that host with vgpu and see if it blows up
22:08:33 mriedem if it fails, we can assert it should fail until https://review.openstack.org/#/q/topic:use-nested-allocation-candidates+(status:open+OR+status:merged) fixes it
22:08:37 mriedem and rebase those on top
22:08:41 mriedem LIKE A CHAMP
22:08:53 efried mriedem: What ought to happen is: the fake libvirt driver should (by default? based on fixture setup?) call the real libvirt driver's impl of update_provider_tree, which should be modified to do reshaping for vgpus in this cycle (and maybe other things) so we can actually test those things in functional tests.
22:09:03 bauzas mriedem: https://github.com/openstack/nova/blob/master/nova/tests/functional/test_servers.py#L1835 ?
22:09:10 bauzas oh shit, sorry
22:09:11 mriedem bauzas: yes just linked that above
22:09:15 mriedem gawd!
22:09:19 efried mriedem: But we should (still) absolutely not move the mocked-up update_provider_tree-of-bizarreness from that mock to the fake libvirt driver. It just doesn't make sense.
22:09:32 mriedem efried: i will cut your damn letter jacket
22:09:32 bauzas I should employ someone to read my IRC
22:09:50 mriedem efried: honestly i don't care how it's done
22:09:51 efried Just try it. Actually, the last guy who said that was also named Matt.
22:09:53 mriedem just that it's tested
22:09:54 openstackgerrit sean mooney proposed openstack/nova master: libvirt: delegate ovs plug to os-vif https://review.openstack.org/602432

22:21:07 jroll melwitt: https://docs.openstack.org/ironic/latest/install/configure-nova-flavors.html
22:23:42 melwitt jroll: yeah, I'm pretty sure that override will _not_ stop quota counting from considering and summing the values in the flavor
22:25:20 sean-k-mooney mriedem: o/ fixed now on irc
22:26:44 melwitt jroll: we count the 'vcpus' and 'memory_mb' columns in the 'instances' table to count as quota usage. and I don't think the extra spec overrides will affect how those columns are populated
22:26:52 melwitt and those values come from the flavor
22:30:47 mriedem sean-k-mooney: https://etherpad.openstack.org/p/nova-network-removal-rocky
22:31:01 mriedem there are still some apis to investigate there
22:31:46 sean-k-mooney mriedem: thanks i have bookmarked it ill take a look

03:27:30 yikun and I will rebase your main patch on it soon. : )
03:28:30 brinzh Ok, thank you.
03:29:32 brinzh This should be merged as quickly as possible
03:39:28 pvc hi guys
03:39:31 pvc yikun
03:39:32 pvc brinzh
03:39:56 yikun yep?
03:47:23 pvc is tesla p100 supports vgpu?
04:51:18 pvc yikun
04:51:21 pvc hello yikun
05:01:14 pvc hi

05:42:00 pooja_jadhav mriedem: hello
05:45:32 brinzh pvc: this maybe need the specific driver package with the p100, or others, we alse need this ^^
05:45:58 pvc i have my centos server with p100 on it
05:46:03 pvc but i cannot see any mdev bus
05:46:25 pvc https://docs.openstack.org/nova/queens/admin/virtual-gpu.html
05:48:16 brinzh pvc: We also have been read this, and cannot find the mdev bus.
05:49:23 brinzh pvc:I don't know if I need support from NVIDIA driver.
05:49:45 pvc so how i can enable the vgpu?
05:49:51 pvc if ever i just passthrough it to my instance
05:50:28 brinzh all: If a friend has done something similar, please give guidance.^^
05:51:48 brinzh passthrouth diff with vgpu...
