#openstack-nova - 2019-02-12
16:58:34 stephenfin jangutter, sean-k-mooney: Per our discussion on IRC last week ^
16:59:32 lyarwood dansmith: so just to confirm, you'd be okay with https://review.openstack.org/#/c/551302/ as a backportable hack if the partial was moved down and we followed up with something different in master?
16:59:52 dansmith lyarwood: yeah
17:00:10 lyarwood dansmith: kk, I'll move that down now then, thanks
17:03:10 stephenfin mriedem, alex_xu: Any chance you could take a look at this again as some point this week? https://review.openstack.org/#/c/631038/
17:04:51 openstackgerrit Lee Yarwood proposed openstack/nova master: Avoid redundant initialize_connection on source post live migration https://review.openstack.org/551302
17:05:20 lyarwood dansmith: ^ there we go, thanks again
17:06:17 prometheanfire does nova require pci_passthough_whitelist to be in the [pci] section in rocky or can it remain in [DEFAULT]?
17:10:05 stephenfin prometheanfire: It will be read from DEFAULT but it should be moved as we'll eventually remove the aliases
17:10:47 stephenfin prometheanfire: You'll get a warning. Also, the option in the '[pci]' group is simply called 'passthrough_whitelist', in case you'd missed that
17:11:04 prometheanfire ya
17:11:24 prometheanfire I'm working on a os_nova backport to stable/rocky, stein is already updated
17:11:26 sean-k-mooney it was technically moved in queens i think
17:11:35 prometheanfire ya, docs show it in pike too
17:11:44 prometheanfire https://docs.openstack.org/nova/pike/admin/pci-passthrough.html
17:12:15 sean-k-mooney prometheanfire: oh it was move in ocata
17:12:36 prometheanfire no one uses that :P
17:13:11 sean-k-mooney you would be surprised how many people are on Newton still
17:13:41 sean-k-mooney there are still people on liberty but yes few people use ocata
17:13:53 sean-k-mooney its EOL upstream anyway
17:14:19 prometheanfire it was a joke :P
17:14:48 sean-k-mooney but anyway https://github.com/openstack/nova/blob/master/nova/conf/pci.py#L84
17:15:14 sean-k-mooney we still support both but we really shoudl drop support for [DEFAULT] at this point
17:15:28 prometheanfire ya
17:16:26 sean-k-mooney prometheanfire: if you are moving it yyou shoudl also move the pci alias too
17:17:07 sean-k-mooney https://github.com/openstack/nova/blob/master/nova/conf/pci.py#L23
17:18:34 prometheanfire alias wasn't even defined/used until stein (I'm adding it in the backports)
17:19:03 sean-k-mooney they predate kolla by years
17:19:22 sean-k-mooney you could use them via the config override mechanisium
17:20:14 sean-k-mooney the main issue was you could only have 1 alsi tuse to how the config_merger ansible plugin worked
17:20:35 sean-k-mooney it does not support MultiStrOpt fields
17:21:17 sean-k-mooney unlike the whitelist the alais does not support a json list format
17:30:05 prometheanfire does nova support out of tree drivers? (xenxl)
17:33:01 melwitt o/
17:33:18 sean-k-mooney prometheanfire: nova does nto support out of tree drivers in general no
17:36:22 prometheanfire sean-k-mooney: ok, just curious
17:44:06 stephenfin sean-k-mooney, adrianc: Finished SR-IOV series review and left some comments. Ping me if/when there's more to look at.
17:44:32 sean-k-mooney stephenfin: cool i will try to adress them later today
17:47:00 sean-k-mooney stephenfin: it can wait till tomorow but we need to review https://review.openstack.org/#/c/636061/ tool the ironic and neutron spec were approved after m2 so apparently this is intending to target stien.
17:48:45 sean-k-mooney stephenfin: so 1 we need to validate it makes sense and 2 merge it and releas a new os-vif version before teh 27th. i was hoping to do a new release on friday week anyway but i would have prefered to at least have a nova/os-vif blueprint for this earlier
17:48:46 prometheanfire sean-k-mooney: they don't think they'd be able to support the driver fully upstream is the reason I asked
17:49:40 sean-k-mooney prometheanfire: so technically you can use out of tree drivers but they are not offically supported by nova (since they are out of tree) and nova may break them at any time
17:50:04 sean-k-mooney historically i dont know how volitile that interface has been
17:50:22 openstackgerrit Surya Seetharaman proposed openstack/nova master: Plumbing required in servers ViewBuilder to construct partial results https://review.openstack.org/635146
17:50:23 openstackgerrit Surya Seetharaman proposed openstack/nova master: API microversion 2.69: Handles Down Cells https://review.openstack.org/591657
17:50:23 openstackgerrit Surya Seetharaman proposed openstack/nova master: API microversion 2.69: Handles Down Cells Documentation https://review.openstack.org/635147
17:50:34 sean-k-mooney prometheanfire: so there is noting preventign kolla from supproting deploying them but they may break
17:52:15 sean-k-mooney prometheanfire: being out of tree means that maintaining comptablity with nova fall entirly onto the xenxl team. but yes being intree requires ci and other testing requirement so its non trivial
17:54:04 prometheanfire sean-k-mooney: not asking for osa (or kolla), that comes as the cost of out of tree :D
17:54:37 sean-k-mooney well being out of tree has benifits too
17:55:07 sean-k-mooney if the hypervior you are intergrating with is evolving quickly you can add features and adapt your driver much faster out of tree
17:55:44 sean-k-mooney so it best to bring it in tree when it stable and you have hit the baseline of feature you want o support
17:56:45 prometheanfire yep
17:58:42 odyssey4me prometheanfire OSA has implementations of out of tree drivers for nova already - for powervm IIRC
17:59:14 prometheanfire odyssey4me: good point I'll point him there
17:59:19 odyssey4me nova supports the use of out of tree drivers, but obviously the core team for nova does not 'support' those drivers - that'd be for the out of tree driver team
17:59:42 odyssey4me OSA also has nova-lxd driver support
18:09:51 openstackgerrit Paul-Emile Element proposed openstack/nova master: Add emulated TPM support to Nova https://review.openstack.org/631363
18:17:29 prometheanfire the pci_whitelist can accept a value like passthrough_whitelist= "{ "vendor_id": "10de", "product_id": "15f7" }" ?
18:17:42 prometheanfire or does it need to look like { "vendor_id": "10de", "product_id": "15f7" }
18:24:45 sean-k-mooney the later i think
18:25:13 sean-k-mooney prometheanfire: there a a bunch of examples here https://github.com/openstack/nova/blob/master/nova/conf/pci.py#L128-L162

18:39:23 melwitt edleafe: ack, thanks
19:13:52 openstackgerrit Kashyap Chamarthy proposed openstack/nova master: libvirt: Bump MIN_{LIBVIRT,QEMU}_VERSION for "Stein" https://review.openstack.org/632507
19:14:39 kashyap Only 16 more tests to fix! (Down from 34.)
19:15:29 kashyap mriedem_afk: ^ When you get a moment: I think it makes sense to get the above in in Stein (even at the end of the release). IMHO, it just gets rid of the needless cruft
19:16:12 kashyap The unit test "noise" is largely mechanical (as I noted in the commit message): remove the needless extra serial device.
19:17:33 kashyap I'll fix the rest of the 16 tests in the morning.
20:28:00 openstackgerrit Kashyap Chamarthy proposed openstack/nova master: libvirt: Bump MIN_{LIBVIRT,QEMU}_VERSION for "Stein" https://review.openstack.org/632507
20:28:38 kashyap Alright, actually rest of the 16 are fixed, too.
20:50:32 mriedem huh i see the 12.0.0 liberty GA release notes aren't published https://docs.openstack.org/releasenotes/nova/liberty.html
20:54:07 mriedem dansmith: you wanna help get the legacy-grenade-dsvm-neutron-multinode-live-migration job fixed? https://review.openstack.org/#/c/634962/ already +2d
20:55:31 dansmith DO I EVER
20:55:43 mriedem not sure why that job isn't voting, probably should be
20:55:58 mriedem seems like live migrating back and forth across n and n-1 nodes is good to keep working..
21:00:46 cfriesen dansmith: how does https://git.openstack.org/cgit/openstack/nova/commit/?id=804215017f38300ac429e4401ce9c23f0c8ff3c6 avoid the traceback when it saves and re-raises the exception?
21:02:50 dansmith cfriesen: I think the point of that was to log the important details where we had them, which are lost in the generic stack trace above
21:02:52 mriedem cfriesen: i think the point is it's avoiding this https://review.openstack.org/#/c/546423/5/nova/virt/block_device.py@313
