#openstack-nova - 2019-04-25
14:24:33 sean-k-mooney then as we add usage in nova we can extend the defualt of the config option
14:24:53 aspiers efried: no I was talking specifically about https://docs.openstack.org/os-traits/latest/contributor/index.html
14:25:07 aspiers efried: but I was also about to ask whether I should submit a follow up to https://review.opendev.org/#/c/655671/ to "rename" the SEV trait (deprecating the original) ?
14:25:16 aspiers efried: or whether I should instead amend that review
14:25:30 aspiers I guess amending makes more sense
14:25:40 efried aspiers: I think kashyap is going to do that as part of his patch, because he's going to be splitting x86 into amd and intel
14:25:50 efried It could be done as separate patches, but meh.
14:26:41 aspiers kashyap: when do you expect your reorg to land?
14:27:36 kashyap aspiers: As soon as I address the feedback :-) We can work it out
14:27:53 openstackgerrit Surya Seetharaman proposed openstack/python-novaclient master: Microversion 2.73: Support adding the reason behind a server lock https://review.opendev.org/648659
14:28:03 efried kashyap: CPU with hypervisors spec is merging and bp is approved, striking from PTG agenda, cool?
14:28:43 mriedem btw, with trait names like HW_CPU_X86_POTENTIAL_SECURITY_VULNERABILITY_NO_SSB i look forward to the day when we blast the url limit for GET query params
14:29:05 openstackgerrit Matt Riedemann proposed openstack/nova master: DNM: debug config opts infinite recursion https://review.opendev.org/654468
14:29:07 efried I was being facetious with that.
14:29:08 sean-k-mooney mriedem: im sure we already to if we try to use everything we currently support
14:29:23 efried mriedem: By then we'll surely have json payload for requests.
14:29:30 jaypipes mriedem: coupled with NET_BW_EGR_KILOBIT_PER_SEC, that would be awesome.
14:29:51 jaypipes used to be even longer than that :)
14:29:51 aspiers kashyap: just trying to work out the order of work, since a lot of these changes depend on each other
14:29:56 sean-k-mooney efried: if we do have a json payload we will also need to use a post not a get
14:30:04 efried you keep saying that :P
14:30:10 openstackgerrit Matt Riedemann proposed openstack/nova master: DNM: debug config opts infinite recursion https://review.opendev.org/654468
14:30:10 openstackgerrit Matt Riedemann proposed openstack/nova master: Don't run tempest/devstack jobs on nova/test.py only changes https://review.opendev.org/655121
14:30:12 sean-k-mooney i do
14:30:32 efried I'm sure you must be right. I don't really care what http verb it is.
14:30:35 aspiers do we have any mechanism for plotting dependency graphs between commits in Gerrit?
14:30:47 efried aspiers: You mean visually?
14:30:47 sean-k-mooney because i keep seeing peole propose apis with get bodies
14:31:05 mriedem efried: gibi: ^ so that series now does 2 things: 1. the nova change sets a low recursion limit (probably won't help) and 2. the oslo.config change doesn't print, it just counts recursion and raises if we call _get() more than 5 times on the same option
14:31:26 efried mriedem: ack
14:31:36 kashyap aspiers: Will address that as quickly as I can.
14:31:38 gibi mriedem: ack, fingers crossed
14:31:49 efried aspiers: And do you mean dependencies based on line conflicts, or based on commits in series and Depends-On?
14:32:02 efried The former is displayed in gerrit, top right corner, "Conflicts With"
14:32:02 openstackgerrit Merged openstack/nova-specs master: Add "CPU selection with hypervisor consideration" spec https://review.opendev.org/645814
14:32:14 efried ^ kashyap \o/
14:32:31 aspiers efried: commits in series and Depends-On
14:32:45 kashyap efried: In your "copious free time", want to respond to Ed here on "NO_{trait_name}", since your "Traits muscle" is better trained? -- https://review.opendev.org/#/c/655193/2/os_traits/hw/cpu/amd.py@19
14:33:07 aspiers efried: well, IMNSHO https://github.com/aspiers/git-deps does a nicer job of the former ;-)
14:33:41 efried aspiers: I know of no graphical tool, but that definitely doesn't mean there isn't one. Might ask the infra guys
14:33:42 kashyap efried: Thank you! IIRC, it is "encouraged" to update the spec file as "new information arises" (I know jaypipes likes to use Labowski's phrase here :D)?
14:34:10 aspiers efried: yeah I was thinking of something like the way launchpad shows a dep graph for blueprints
14:34:16 efried kashyap: Yes, definitely. Common practice to propose spec amendments e.g. once the impl lands to make it reflect reality.
14:34:36 kashyap Alright, I've seen a few amendments in the specs repo.
14:34:53 mriedem gibi: i see you have https://blueprints.launchpad.net/nova/+spec/support-server-move-operations-with-ports-having-resource-request which your move spec is tracked against, and you also have https://blueprints.launchpad.net/nova/+spec/enhance-support-for-ports-having-resource-request
14:34:53 aspiers efried: speaking of which, I noticed one of the SEV work items might need changing but I'm not sure
14:34:54 efried kashyap: I can do that (respond to edleafe in the review) or you could just point to the eavesdrop of the conversation we had above.
14:35:00 mriedem gibi: does the former supersede the latter?
14:35:14 kashyap efried: Okay, I'll do the latter; it'll save you time.
14:35:21 efried kashyap: thanks
14:35:29 mriedem gibi: or is the latter the reason for ptg discussion?
14:35:35 gibi mriedem: https://blueprints.launchpad.net/nova/+spec/enhance-support-for-ports-having-resource-request is a collection of further enhancements for bandwidth
14:35:41 aspiers efried: work item #7 http://specs.openstack.org/openstack/nova-specs/specs/train/approved/amd-sev-libvirt-support.html
14:35:43 efried mriedem: As I understand it, enhance-support is an overarching longer-term bp that excludes support-server-move
14:35:54 mriedem ok
14:36:10 gibi mriedem: on the ptg I would like to get decision about 1) the microversion for move 2) the priority of the items in https://blueprints.launchpad.net/nova/+spec/enhance-support-for-ports-having-resource-request
14:36:20 aspiers efried: should it be checking the trait or the resource class? I guess only the trait is SEV-specific and so is the required XML, so maybe this is still correct
14:36:40 mriedem btw, we have a working multi-cell ci job https://review.opendev.org/#/c/655222/
14:36:53 efried aspiers: I would check the allocation. Remember, the request won't necessarily include the trait.
14:37:22 efried aspiers: So yeah, that should be amended at some point.
14:37:34 dansmith is this a known thing? http://logs.openstack.org/37/655137/2/check/openstack-tox-lower-constraints/6363387/testr_results.html.gz
14:37:36 efried You may want to open a change set with that, but leave it -W to collect such deltas as they arise.
14:37:43 dansmith testrpc fail
14:37:47 kashyap aspiers: BTW, to quickly answer on the SEV trait -- I'd suggest to keep it as-is: HW_CPU_AMD_SEV (in amd.py)
14:37:48 dansmith on a lower constraints job no less :)
14:37:55 aspiers efried: I was thinking the request filter could add not only resources:MEM_ENCRYPTION_CONTEXT=1 but also traits:HW_CPU_X86_AMD_SEV=required
14:37:59 efried dansmith: yes, that's bug...
14:38:06 kashyap aspiers: Because we'll be consolidating all AMD-related stuff in one place, as it should be.
14:38:14 efried dansmith: bug 1825435
14:38:15 openstack bug 1825435 in OpenStack Compute (nova) "TestRPC unit tests intermittently fail with "'>' not supported between instances of 'NoneType' and 'datetime.datetime'" - maybe due to "Fatal Python error: Cannot recover from stack overflow."" [High,Confirmed] https://launchpad.net/bugs/1825435
14:38:21 dansmith ack
14:38:31 aspiers kashyap: so not under HW_CPU_X86_AMD?
14:38:56 aspiers isn't that the opposite of what efried wrote 20 mins ago?
14:39:20 kashyap aspiers: Wait, disregard me. I'll re-read the chat and slow-respond later.
14:39:26 aspiers kashyap: OK :)
14:39:34 efried aspiers: We talked about this. The request filter shouldn't do that. The admin (or whoever authors the flavor/image-meta) should request SEV via the trait if they want SEV specifically. Otherwise you could theoretically land anywhere that supports mem enc.
14:40:01 aspiers efried: but at some point in the workflow the code needs figure out that SEV is the technology which will be used to implement it. Where should that happen?
14:40:26 aspiers I guess your point is that doing it in a request filter is too early
14:40:36 sean-k-mooney aspiers: in the virt dirver
14:40:41 efried aspiers: Right; at spawn time, libvirt will use the same mechanism it used to decide to expose that trait in the first place.
14:41:07 efried aspiers: ...or possibly just look for the trait itself as already exposed, not sure if you have access to the provider tree in spawn
14:41:14 sean-k-mooney placment will land the vm on a host that support mem encryption and then the virt driver can figure out which tech implementes it
14:41:20 efried ^
14:41:31 aspiers yeah makes sense
14:42:20 mriedem dansmith: yes
14:42:24 openstackgerrit Matt Riedemann proposed openstack/nova master: Enable n-novnc in nova-multi-cell job https://review.opendev.org/655711
14:42:24 openstackgerrit Matt Riedemann proposed openstack/nova master: Add nova-multi-cell job https://review.opendev.org/655222
14:42:32 openstackgerrit Lee Yarwood proposed openstack/nova master: libvirt: Stop ignoring unknown libvirtError exceptions during volume attach https://review.opendev.org/655696
14:42:33 openstackgerrit Lee Yarwood proposed openstack/nova master: libvirt: Always disconnect volumes after libvirtError exceptions https://review.opendev.org/655712
14:42:38 mriedem http://status.openstack.org/elastic-recheck/#1825435
14:42:58 aspiers efried, sean-k-mooney: so other than updating the commit message and maybe the trait name, I think https://review.opendev.org/#/c/633855/ can remain the same
14:43:04 mriedem http://lists.openstack.org/pipermail/openstack-discuss/2019-April/005392.html
14:43:07 dansmith mriedem: I didn't get an e-r report on it
14:43:20 mriedem dansmith: e-r bot has been off for weeks as far as i know
14:43:25 openstackgerrit Stephen Finucane proposed openstack/os-vif stable/stein: Prevent "qbr" Linux Bridge from replying to ARP messages https://review.opendev.org/655678
14:43:30 mriedem dansmith: i have a couple of debug patches up to try and recreate to figure out what's causing the recursion stack dump
14:43:30 aspiers efried, sean-k-mooney: and I'll add a separate review which adds the new config option and inventory of the new resource class from it
14:43:42 dansmith mriedem: consider me shamed
14:43:50 mriedem dansmith: https://review.opendev.org/#/q/topic:bug/1825435+status:open
14:44:10 mriedem if you have ideas on that it'd be cool because so far my recreate attempts are failing
