gibisean-k-mooney: hi! There is a SRIOV NIC, couple of VF is created on the PF and then both PF and VFs are whitelisted in nova compute. Then booting a VM with a direct-physical port nova will allocated the PF and makes the VFs unavailable. But which module (nova, neutron, libvirt) makes sure that the VFs are deleted?10:21
gibiDoes it work like the following? libvirt detaches the PF from the host and that makes the VFs deleted?10:22

xinranwanggibi: Hi gibi, as we discussed in nova spec, a new vnic type is needed for device managed by cyborg. I create a neutron RFE for this, and there is some question posed. Could you please check it ? https://bugs.launchpad.net/neutron/+bug/190910011:51
openstackLaunchpad bug 1909100 in neutron "[RFE]add new vnic type "cyborg"" [Wishlist,Confirmed] - Assigned to Rodolfo Alonso (rodolfo-alonso-hernandez)11:52
gibixinranwang: I deferr to sean-k-mooney and the neutron folks here. From my perspective what nova needs is a way to know that the port needs a special handling (talking to cyborg) during boot.11:54
xinranwanggibi:  yes, nova can check the vnic type and trigger the interaction with cyborg then.11:56
gibicommented on the RFE11:56

lyarwoodstephenfin: queued12:02
stephenfingibi: I've closed this bug as WONTFIX. I don't think we have access to PPC nodes in zuul, which means we can't say we support anything other than x86/x86_64. Lemme know if you disagree https://bugs.launchpad.net/nova/+bug/190997212:07
openstackLaunchpad bug 1909972 in OpenStack Compute (nova) "a number of tests fail under ppc64el arch" [Low,Won't fix]12:07
gibistephenfin: I saw that and I have the same problem, I cannot start fixing those tests as I have no way to reproduce the problem12:08
gibi(no I did not tried spinning up a ppc VM with qemu)12:08
stephenfinYeah, I've suggested that zigo simply mark the package as arch-specific. If it's not tested, it's broken12:08
gibistephenfin: did we declare support for ppc somewhere in nova doc?12:08
stephenfinI don't think so12:08
stephenfinWe don't block it but https://github.com/openstack/nova/blob/46899968619e4ea0ff2ab380977619bb29578d43/nova/virt/libvirt/driver.py#L572-L58112:09

zigostephenfin: gibi: My opinion is: if you can't test with PPC, and that the unit test is reported as broken on non-x86_64, then skip it on non-x86_64 rather than just closing the bug ...12:20
sean-k-mooneystephenfin: yes i can take a look at that shortly12:20
stephenfinzigo: what about when someone adds the next test that doesn't work on x86_6412:20
sean-k-mooneygibi: the vf are deleted by the kernel when the PF is passhtough to the vm12:21
zigostephenfin: These issues are *very* rare.12:21
zigoSo we can act on a case-by-case ...12:21
gibisean-k-mooney: thanks12:21
stephenfinI disagree. You skip tests because they're not applicable. These tests are applicable. They simply don't work on PPC12:22
sean-k-mooneythe managed=yes part of <hostdev mode='subsystem' type='pci' managed='yes'> i blelive tells libvirt to manage bining the pf to vfio-pci form its current nic driver and to restore it when the vm is done12:22
stephenfinwho knows what else doesn't work12:22
sean-k-mooneyby which i mean its stop and the pf returns to the host12:23
sean-k-mooneytechnically its udev coupled with the kernel config that decide what driver it goes back too12:23
zigostephenfin: As much as I understand, they would work if s/ide/scsi/ ...12:23
stephenfinPerhaps. I genuinely don't know12:24
sean-k-mooneyif you used udev rules to allocate the vfs then that will recreate them12:24
stephenfinwhich is kind of the point12:24
sean-k-mooneyon the ppc front12:25

sean-k-mooneyyes12:47
lyarwoodyeah that's my bad, smells like I didn't mock out the arch check somewhere12:47
gibisean-k-mooney: could we ask IBM to include unit and functional test in their CI? then we could have coverage and properly fix the test12:47
sean-k-mooneygibi: we can always ask but not sure if it will happen :)12:48
zigoThis is also a problem on arm, FYI.12:48
zigo(the above 2 unit tests failing...)12:48
sean-k-mooneyi might reach out to our multi arch folks downstream and see if they can help12:48
sean-k-mooneywe do package nova for ppc64el downstream and we have limited downstream ci for it12:49
sean-k-mooneypresumably that shoudl included unit and functional test but they may still be priamlary working with 16 which is train or relying on x86 runs12:49
sean-k-mooneyfor unit and functional12:50
sean-k-mooneyzigo: for arm we can test that in the gate12:50
sean-k-mooneyzigo: we have limited ablity to run thigns in the arm check pipeline12:51
sean-k-mooneywell we can run anything we want in that pipeline just limited capsity12:51
sean-k-mooneyrunning unit and funcitonal there i think would be ok12:51

jawad_axdHi nova folks, I have done passthrough nvidia k20c with window 10 instance. Installed latest drivers from nvidia site. I can see " This device is working properly" in device manager.Apparently, gpu is not being used for any application. I can see only developer task in nvidia control panel.No 3D settings where I can set to use GPU for windows. Why 3D settings are missing in nvidia control panel? Is it14:17
jawad_axdsomething with nvidia driver or windows or openstack..Anybody had same problem or any suggestions? Thanks14:17
dansmithstephenfin: oof, yeah that probably needs several sets of eyes. I won't get to it today, but maybe next week14:24
stephenfinAgreed. Any time in the near future is good14:25
artomstephenfin, I suppose if every reviewer runs your tool manually it's as good as CI14:36
artomWe'd also need to make sure your tool has no bugs, but then that's the same as with a CI job14:36

jawad_axd@bauzas Yes14:53
bauzasso, it's either a windows or a nivdia issue, sorry14:54
sean-k-mooneyjawad_axd: i assume if you look in the device manager the device is there with the nvida drivae but error 4314:54
sean-k-mooneyjawad_axd: it looks like nvidia has updated there driver detection logic recently and broken our ablity to do pci passhtouhg again14:54
sean-k-mooneybauzas: i did pci passhtough of my gtx-780 last week and found our hypervior hiding code nolonger is sufficent14:55
sean-k-mooneyerror 43 is back14:55
jawad_axd@sean-k-mooney There is no error 43. Device manager shows device working properly.14:55
bauzaswhat ?14:55
jawad_axdI had error 43 with genforce GTX 780. But with this Tesla gpu, driver installed successfully.14:56
sean-k-mooneyjawad_axd: ok then in that case have you disabel the video device so its the only gpu14:56
sean-k-mooneyjawad_axd: ya the tesla driver stack allows virutalistation14:56
sean-k-mooneyit does not have the same test14:57
sean-k-mooney*check14:57
sean-k-mooneyjawad_axd: you could add hw_video_model=none to the image as a test14:57
sean-k-mooneyjawad_axd: that would disable the software gpu emulation in qemu so the only gpu would be the nvidia one14:57
jawad_axd@sean-k-mooney Thanks. I try this hw_video_model=none .14:58
sean-k-mooneybefore you do if you install gpuz in the vm does it detect support for cuda/driectx ectra14:58
jawad_axd@sean-k-mooney gpuz detects gpu.14:59
sean-k-mooneyjawad_axd: and it has all the apis available?14:59
sean-k-mooneyif so i would guess the other application are just selecting the first gpu which will be the cirros/virtio/qxl one form qemu14:59
sean-k-mooneyjawad_axd: tensorflow used to do this for example which is why hw_video_model=none was added15:00
jawad_axd@sean-k-mooney hw_video_model=none  would stop using qxl/virtio, right ?15:00
sean-k-mooneyyep15:01
sean-k-mooneyso the only gpu the guest will see it the pci passthough one15:01
jawad_axd@sean-k-mooney What do you mean by apis in gpuz?15:07

sean-k-mooneyfor cuda directx opengl15:08
sean-k-mooneyand some others15:08
sean-k-mooneyjust wanted to confim the expected api were avaiable15:08
sean-k-mooneyand that it was usign the nvida driver not the generic vga windows direver15:08
jawad_axdIt has OpenCL, CUDA and OpenGL1.1 checked.15:09
sean-k-mooneyyep so the nvidia direr is really working then15:09
sean-k-mooneyif they were not check then it might be using the fallback driver instead of the nvidia one15:10
sean-k-mooneyso i would guess its just a gpu selection issue cause by both of them being there15:10
jawad_axdAlright. I try hw_video_model=none . Will get back if it works :)15:11

dansmithsean-k-mooney: do you know of any instances where we use the raw keystoneauth stuff to just make a quick call to another service, but with all the request info we got (i.e user token etc)?15:41
dansmithlooking for something to copy15:41
sean-k-mooneymaybe in the ironic code15:43
dansmithokay I think we used to talk to placement like that didn't we?15:43
sean-k-mooneymaybe but i think palcment now uses the sdk15:43
dansmithalthough not with the user's token I guess15:43
dansmithyeah I know it does now15:43

dansmithironic lazy-imports ironic client, but it's also not using the user's token right?15:45
sean-k-mooneyya that im not sure about it look like that is using the config options15:45

sean-k-mooneydansmith: i guess for ironic and placment we just use admin tokens since they are normally admin only apis right15:47
*** macz_ has joined #openstack-nova15:47
sean-k-mooneyso we just use the configs15:47
dansmithright15:47
sean-k-mooneydo you need ksa or could you just use the sdk15:47
dansmithwell, I'm trying to PoC something where glance calls to itself,15:48
*** spatel has quit IRC15:48
sean-k-mooneytoo answer you question though i dont know off the top of my head15:48
dansmithso I could just import glanceclient, but I really just need to replay an http call so it seems a little heavy15:48

stephenfindansmith: https://review.opendev.org/c/openstack/nova/+/706295/7/nova/network/neutron.py15:55
stephenfinIf I understood you correctly, I think that's what we do for port bindings in neutron15:55
dansmithstephenfin: ah, yeah that might be it, thanks15:57
dansmithI figured even though neutron was the right pattern, that everything would be through the client and not helpful,15:57
dansmithbut that chunk is like "in case of no client support, break glass" :)15:57
jawad_axd@sean-k-mooney Apparently , hw_video_model doest work with none' anymore? I am getting invalid metadata.. I guess valid options are just graphics adapter model with this property..16:05

jawad_axdI am using stein16:39
*** whoami-rajat___ is now known as whoami-rajat__16:39
sean-k-mooneyah you one release too old16:39
sean-k-mooneyin your case i think your only really choice other then upgrading is to force the applciations to use the gpu via there config or runtime options16:40
sean-k-mooneyjawad_axd: the image properties are defiend in oslo versions objects so there is no way to backport support for none with out upgrade issues16:41
sean-k-mooneyform a nova poing of view the phsyical gpu passthough is working correctly but the applciaiton is just not selceting the correct gpu of the two avaiable16:42
*** ociuhandu has quit IRC16:44
jawad_axdAlright..16:45
sean-k-mooneysorry cant help more but once nova has succfully booted the vm and made the gpu avaiable to it its jobs is basically done16:46
jawad_axd@sean-k-mooney Atleast I got to know, passthrough is working fine. Now I need to figure out how to use it as default. Thanks16:56

sean-k-mooneystephenfin: i think we should do that optimisation but im kind of with gibi that it could be a follow up patch17:21
sean-k-mooneyi know you are also looking a provideing a generic way to do the waits in https://review.opendev.org/c/openstack/osc-lib/+/76250317:22
sean-k-mooneyso i can see why you would prefer not to do it direcly in https://review.opendev.org/c/openstack/python-openstackclient/+/762396 and wait to reuse that17:23

sean-k-mooneyyou welcom to review the whole spec obviously but this spcificly would be good for you to weigh in on18:47
gmannsean-k-mooney: sure18:47
sean-k-mooneybasiclaly blocking live migation with vdpa using a 403 until we support it to avoid a micorverion bump on the api side18:48
*** ociuhandu has joined #openstack-nova18:48
sean-k-mooneywhen ever qemu actully add suport we would still need to check the compute capabliteis and may fail if both the source and destionation nodes are not updated18:49
sean-k-mooneyso even if we had a microversion saying nova supports this we would no know if your qemu supported it so i dont think a microverion is the way to go since there are no api changes involved18:50
artomsean-k-mooney, yep, got the email. I'll be honest, understand your changes and replying will go to next week :)18:53
