| 21:32:38 | arjunbaindur | any idea how to get them to show up as two functions under the same slot | |
| 21:32:39 | sean-k-mooney | or a similar device | |
| 21:32:56 | sean-k-mooney | unfortunetly we do not have a way to do that currently | |
| 21:33:12 | sean-k-mooney | we did dicuss it breifly about 3-6 months ago | |
| 21:33:46 | sean-k-mooney | efffectivly we would need to modify the pci alisia to support multifuntion devices | |
| 21:34:46 | sean-k-mooney | such as allowing one pci aliase to refrence another and adding a multifuntion=true tag | |
| 21:35:17 | sean-k-mooney | so the parent alias would refence the child aliase and but or would have the multifunction=ture tag | |
| 21:36:13 | sean-k-mooney | arjunbaindur: i think on windows this can break the audio encoder on nvidga gpus since the driver is expecting it to be a second fuction on the same bus/slot | |
| 21:36:18 | sean-k-mooney | but on linux it works | |
| 21:36:34 | sean-k-mooney | im sure it would be an issue for other device that had the same toplogy | |
| 21:39:01 | arjunbaindur | to be specific, this is a Xilinx card | |
| 21:39:12 | arjunbaindur | https://www.xilinx.com/support/documentation/boards_and_kits/accelerator-cards/1_5/ug1301-getting-started-guide-alveo-accelerator-cards.pdf | |
| 21:39:57 | arjunbaindur | since the two devices show up under diff PCI slots, we arent able to install drivers | |
| 21:40:35 | sean-k-mooney | ah ok well its the same issue unfortunetly | |
| 21:40:48 | sean-k-mooney | are you trying to reproguam the aclerat using 1 fucntion | |
| 21:40:56 | sean-k-mooney | and consume it using the second | |
| 21:42:54 | sean-k-mooney | 32-64GB of ddr4 + and fpga and some qsfp ports. that looks like a pretty interesting card | |
| 21:43:14 | sean-k-mooney | arjunbaindur: are you trying to use this via cyborg or just novas pci passhtough | |
| 21:44:08 | arjunbaindur | just Nova PCI passthrough: followed this doc basically: https://docs.openstack.org/nova/rocky/admin/pci-passthrough.html | |
| 21:44:41 | arjunbaindur | Added the two PCI addresses for each function in the whitelist | |
| 21:44:42 | sean-k-mooney | ya so as i said we are missing the ablity to group multiple fucntion together form teh same device that are schulded togehter | |
| 21:45:07 | arjunbaindur | is there an upstream bug or anything to track this? | |
| 21:45:28 | sean-k-mooney | i was trying to find one. its not really a bug since it was never part of the orginial design | |
| 21:46:03 | sean-k-mooney | i suspcet this would need a short spec or maybe a specless blueprint | |
| 21:48:16 | sean-k-mooney | arjunbaindur: looking at the open blueprints no | |
| 21:48:37 | sean-k-mooney | so the feature you need is support for "multifunction pci device passthough" | |
| 21:49:17 | sean-k-mooney | if you want to file a blueprint for that and add the details of your specific usecase we could bring it up in the next meeting or dicsuss it here next week when more people are online | |
| 21:50:07 | sean-k-mooney | it has been asked for before and should not be too invasive to add but on the other hand not many people review the pci code so getting reviews might be the bigger stubleing block to addign this | |
| 21:51:06 | sean-k-mooney | its a cpablity i suspect cyborg will want eventually too so the libvirt driver work to supprot generintg the correct xml is likely to be need regardless of if we add the feature to novas pci pasthough | |
| 22:29:40 | sean-k-mooney | dansmith: it finally passed https://review.opendev.org/#/c/734184/ :) | |
| 22:31:04 | sean-k-mooney | dansmith: ah you modified devstack in the end https://review.opendev.org/#/c/736231 | |
| 23:26:23 | artom | sean-k-mooney, if by some weirdness of circumstance you're still working: https://review.opendev.org/#/c/737052/2 | |
| 23:32:41 | sean-k-mooney | im watching a c++ code review of command and conquer https://www.youtube.com/watch?v=Oee7gje-XRc&t=929s | |
| 23:33:02 | sean-k-mooney | but since my laptop is broken im using my work one | |
| 23:33:12 | sean-k-mooney | until i buy a new one | |
| 23:33:31 | sean-k-mooney | so ya you unabandonted that? | |
| 23:33:44 | sean-k-mooney | or is this a different fix | |
| 23:34:34 | sean-k-mooney | that is instead of https://review.opendev.org/#/c/737038/ | |
| 23:36:34 | sean-k-mooney | artom: ah ok i see whats happening we are installing pacages via pip before devstack runs for crudini | |
| 23:36:43 | sean-k-mooney | so devstack has not allready installed pip | |
| 23:44:34 | sean-k-mooney | artom: so this is happing because of http://lists.openstack.org/pipermail/openstack-discuss/2020-June/015204.html | |
| 23:44:49 | sean-k-mooney | artom: so +2 from me the ci passes and the patch makes sense | |
| 23:46:32 | artom | I dunno what I expected | |
| 23:46:34 | artom | Thank you! | |
| 23:46:37 | artom | Also, you're a lunatic | |
| 23:46:51 | sean-k-mooney | for likeing c++ | |
| 23:46:56 | artom | Sure, why not | |
| 23:47:15 | sean-k-mooney | or for having irc open on a different monitor while i watch youtube | |
| 23:48:05 | artom | That last part is almost reasonnable | |
| 23:48:16 | dansmith | sean-k-mooney: it didn't setup glance properly though, for some devstack reason I don't understand | |
| 23:48:24 | dansmith | so I'll have to work on that on monday | |
| 23:49:02 | sean-k-mooney | dansmith: ah ok i can take a look on monday too if you like the main issue is i dont know how to configure what you want to configure | |
| 23:49:10 | sean-k-mooney | dansmith: but let me know if i can help | |
| 23:49:32 | dansmith | sean-k-mooney: well, you can see what I've got in local.conf, and that didn't end up in glance-api.conf like it did before | |
| 23:49:47 | dansmith | but anyway, I can take a look and then come crawling to you, which'll make it even more sweet for you :) | |
| 23:50:00 | sean-k-mooney | :) | |
| 23:52:51 | sean-k-mooney | oh ya https://zuul.opendev.org/t/openstack/build/d083edcf35d649768506fbbf7dbbf64c/log/controller/logs/etc/glance/glance-api_conf.txt does not have the values but https://zuul.opendev.org/t/openstack/build/d083edcf35d649768506fbbf7dbbf64c/log/controller/logs/etc/glance/glance-image-import_conf.txt does | |
| 23:53:17 | dansmith | I gotta begin my weekend, later | |
| 23:53:25 | sean-k-mooney | dansmith: o/ | |
| 23:59:04 | sean-k-mooney | dansmith: for what its worth i think your hitting a devstack bug since its in the local.conf correctly. so i think your zuul file is correct. | |
| 23:59:31 | sean-k-mooney | e.g. someitng in devstack is modifying the config after the post config phase which is a bug | |
| 23:59:39 | sean-k-mooney | just a guess | |

| 14:28:41 | jcath | hello, friends, is there a way to make kvm up with both vnc and spice? I try to add spice_listen_address in /etc/libvirt/qemu.conf, but it doesnt work | |

| 09:38:50 | gibi | bauzas: left feedback in https://review.opendev.org/#/c/733703 | |
| 09:38:57 | bauzas | thanks | |
| 09:40:37 | bauzas | gibi: ack, seen your comments | |
| 09:40:43 | bauzas | gibi: honestly, it's a good question | |
| 09:40:58 | bauzas | I'm not opiniated but, | |
| 09:41:23 | bauzas | if we go with the neutron direction, I like it but I won't be able to provide the implementation I think :p | |
| 09:41:48 | bauzas | gibi: so, tbh, I like your concern | |
| 09:42:19 | bauzas | but maybe we should discuss it with some other folks :) | |
| 09:48:52 | brinzhang | gibi, bauzas: I submit a spec, but it has an error of docs. I cannot find which is wrong in line 22 | |
| 09:49:03 | brinzhang | error: /home/zuul/src/opendev.org/openstack/nova-specs/doc/source/specs/victoria/approved/filter-instances-by-tenant-id.rst:22:Unknown target name: "1". | |
| 09:49:12 | brinzhang | https://review.opendev.org/#/c/737241 | |
| 09:49:27 | brinzhang | can you fast check, where caused the error? | |
| 09:52:07 | gibi | bauzas: sure. this is why I said that put every neutron segment - aggregate related code in a single place in nova, so that later we can easily remove it, but I know this part is then becomes implementation detail | |

| 10:19:21 | gibi | brinzhang: the latest PS worked for me locally | |
| 12:05:26 | jcath | friends, I try to use "openstack server add volume --device /dev/hdc instance vol-name" to attach a volume to the instance as an IDE device, but it always attach as a virtio device (qemu-kvm as hypervisor) . as I check nova/virt/libvirt/driver.py, it seems that the device name parameter is ignored... so How I can force to attach a volume on IDE bus? thanks! | |
| 12:06:17 | stephenfin | elod: Could you take a look at https://review.opendev.org/#/c/708617/ today? | |
| 12:12:19 | elod | stephenfin: yes, looking | |
| 12:12:24 | stephenfin | ta | |
| 13:14:54 | tbarron | Is it possible via openstack/nova apis to do expose compute-host extra disks to guest VMs via somthing like pci-passthru? | |
| 13:15:17 | gibi | dansmith, stephenfin, melwitt: sorry I was out Friday afternoon. Thanks for reviewing the image cache bugfix. However I don't like the fact that we are mixing the question of "is this on the same dev?" with the question "is this exists?" | |
| 13:15:45 | tbarron | This has been suggested as a way for kubernetes clusters running with nova vms to do software defined storage (like ceph) without indirection | |
| 13:15:56 | sean-k-mooney | tbarron: in general no. if you have nvme disk you can confiture them for pci pasthough but it expects stateless pci device | |
| 13:16:13 | tbarron | in the data path like when they use RBD backed nova ephemeral or cinder storage | |
| 13:16:20 | sean-k-mooney | so we will not correctly clean them when a vm is deleted and there data will not be copied if you mvoe the guest | |
| 13:16:40 | sean-k-mooney | tbarron: so basically today no | |
| 13:16:49 | sean-k-mooney | tbarron: there is no way to do that | |
| 13:16:54 | stephenfin | gibi: Yeah, I'm on the fence about that now too | |
