| 09:26:36 | sean-k-mooney | 1 move the card to a pci slot that is directly connected to the cpu and not the chipset | |
| 09:26:39 | songwenping | when i set all the devices' driver to vfio-pci, the gpu can passthrough to the vm. | |
| 09:27:13 | sean-k-mooney | 2 check if the bios has the ablity to seperate the devie explictly | |
| 09:27:35 | sean-k-mooney | 3 use the out of tree kernel patch for iommu remapping | |
| 09:28:27 | sean-k-mooney | "PCIe ACS Override for bypassing IOMMU groups support." https://github.com/xanmod/linux-patches/blob/master/linux-5.19.y-xanmod/pci_acso/0001-pci-Enable-overrides-for-missing-ACS-capabilities.patch | |
| 09:30:11 | sean-k-mooney | songwenping: yes that a limitation of vfio-pci | |
| 09:30:21 | sean-k-mooney | "PCIe ACS Override for bypassing IOMMU groups support." https://github.com/xanmod/linux-patches/blob/master/linux-5.19.y-xanmod/pci_acso/0001-pci-Enable-overrides-for-missing-ACS-capabilities.patch | |
| 09:31:34 | sean-k-mooney | would allow you to force the device into its own iommu group if they cant take the simpler options of movign the card to be driectly conneccted to the cpu instead of the chipset | |
| 09:31:43 | songwenping | this patch is relatively new. | |
| 09:31:59 | sean-k-mooney | that version of it | |
| 09:32:09 | sean-k-mooney | the patch has been around for a few years | |
| 09:32:17 | sean-k-mooney | the orginal one is form 2018 | |
| 09:32:36 | sean-k-mooney | correct 2013 https://lkml.org/lkml/2013/5/30/513 | |
| 09:33:09 | sean-k-mooney | i honeestly dont know why this has not landed other then alex is busy with other things | |
| 09:33:17 | sean-k-mooney | it would be really really useful for vms | |
| 09:35:29 | songwenping | thanks, i will try to merge the patch. | |
| 09:36:03 | gibi | sean-k-mooney: I've reviewed the user_data and the rebuild bfv patches. I will go and dig into the func test part ofthe bfv patch now. | |
| 09:36:56 | gibi | sean-k-mooney, stephenfin: if you have cycles then the next 11 PCI patch is ready to land ;) | |
| 09:39:09 | opendevreview | Amit Uniyal proposed openstack/nova stable/victoria: add regression test case for bug 1978983 https://review.opendev.org/c/openstack/nova/+/854979 | |
| 09:39:10 | opendevreview | Amit Uniyal proposed openstack/nova stable/victoria: For evacuation, ignore if task_state is not None https://review.opendev.org/c/openstack/nova/+/854980 | |
| 09:57:39 | admin1 | hi .. i am getting this error: nova-compute Connection to libvirt failed: authentication failed: authentication failed: libvirt.libvirtError: authentication failed: authentication failed and the compute node is unable to register itself .. i am using kolla-ansible yoga .. | |
| 10:14:08 | sean-k-mooney | they changed how they connect | |
| 10:14:29 | sean-k-mooney | that is really a question for the kolla channel since nova was not involved in this change | |
| 10:14:50 | sean-k-mooney | admin1: they enabled more authentication by default | |
| 10:15:42 | sean-k-mooney | admin1: you can tempoarly disable ths use of sasl authentication https://github.com/openstack/kolla-ansible/blob/master/doc/source/reference/compute/libvirt-guide.rst#sasl-authentication | |
| 10:17:01 | sean-k-mooney | noonedeadpunk: was i chating to you about ^ in the past | |
| 10:17:09 | sean-k-mooney | triging to rememebr who hit that before | |
| 10:18:47 | sean-k-mooney | noonedeadpunk: porably wrong user name then | |
| 10:19:13 | sean-k-mooney | im trying to think who works at blizzard | |
| 10:19:37 | opendevreview | Amit Uniyal proposed openstack/nova stable/victoria: add regression test case for bug 1978983 https://review.opendev.org/c/openstack/nova/+/854979 | |
| 10:19:40 | noonedeadpunk | we never did sasl in osa, we use tls certs auth between computes for migrations | |
| 10:19:40 | sean-k-mooney | its been a month or two | |
| 10:19:43 | admin1 | maybe spatel :) | |
| 10:19:59 | sean-k-mooney | noonedeadpunk: tls is more secure for sure | |
| 10:20:00 | noonedeadpunk | afaik he's not from blizzard ) | |
| 10:20:13 | sean-k-mooney | spatel is not no | |
| 10:20:14 | admin1 | yeah | |
| 10:20:39 | sean-k-mooney | i could proably gerp my logs but admin1 that is likely your issue | |
| 10:20:42 | noonedeadpunk | btw talking about auth, it's sad that for offline migrations you still have to ensure SSH connection between computes :( | |
| 10:20:59 | sean-k-mooney | offline you mean cold | |
| 10:21:06 | noonedeadpunk | yeah, sorry, cold | |
| 10:21:26 | sean-k-mooney | ya for the disk copy and more importantly if you are using cpeh/bfv for the file system check | |
| 10:21:30 | noonedeadpunk | as for live migrations libvirt is jsut leveraged | |
| 10:21:34 | sean-k-mooney | that could be remvoed | |
| 10:22:47 | noonedeadpunk | can it? hm, I can recall I still had to ensure ssh even for ceph | |
| 10:22:53 | sean-k-mooney | but it need some changes to how we check for shared filesystem | |
| 10:23:38 | sean-k-mooney | we could replcase the ssh requirement with doign the check via an rpc | |
| 10:23:54 | sean-k-mooney | right now we ssh to the dest and toch a file | |
| 10:23:58 | noonedeadpunk | ah, ok, now I got what you meant | |
| 10:24:00 | sean-k-mooney | then check on the source if we can see it | |
| 10:24:08 | sean-k-mooney | but we could do that via an rpc | |
| 10:24:29 | noonedeadpunk | yeah, I thought the same, but ENOTIME as usual | |
| 10:25:42 | sean-k-mooney | for live migration we actully have the rpcs in place we woudl just do it avia the existing pre-migration rpcs | |
| 10:26:07 | sean-k-mooney | i dont know if we can do the same for cold migratoin today as i dont know if we have rpcs to the dest at the right times that we can extend | |

| 10:54:53 | sean-k-mooney | gibi: did you fiture out why you could not do request_id=uuidutils.generate_uuid(dashed=True) | |
| 10:54:56 | sean-k-mooney | by the way | |
| 10:55:17 | sean-k-mooney | oh nevermind | |
| 10:55:20 | sean-k-mooney | yes we did | |
| 10:55:20 | gibi | yes I did and I already forgot it :) | |
| 10:55:36 | sean-k-mooney | i was the util function | |
| 10:55:42 | sean-k-mooney | you moved it to the object | |
| 10:56:41 | gibi | ahh yes | |
| 10:56:42 | gibi | true | |
| 10:56:55 | sean-k-mooney | https://review.opendev.org/c/openstack/nova/+/853835/9 | |
| 10:57:09 | sean-k-mooney | i was just clenaing up the nova repo i had the DNM change checked out in | |
| 10:57:33 | sean-k-mooney | im going to start backporting the first vdpa patch | |
| 10:57:47 | sean-k-mooney | although i think i need to backport one of your patches first | |
| 10:58:09 | sean-k-mooney | the compute manger restart patch | |
| 10:59:20 | gibi | yeah on the libvirt tests fixture we overlap a bit | |
| 10:59:25 | gibi | hopefully not much | |
| 10:59:37 | sean-k-mooney | well im just using it for one test | |
| 10:59:41 | sean-k-mooney | the evacuate test | |
| 10:59:51 | sean-k-mooney | so i just need to backport it and then rebase on top | |
| 11:00:11 | sean-k-mooney | ah found it https://review.opendev.org/c/openstack/nova/+/850510 | |
| 11:00:44 | sean-k-mooney | ok so im going to try backporting that and then ill cherry pick my patch | |
| 11:05:03 | gibi | now I'm done with the func test part of the rebuild bfv as well. I found nothing serious so I think we can land the series this week | |
| 11:05:21 | gibi | next up is the manila series... | |
| 11:05:47 | gibi | but I need to get food first | |
| 11:05:50 | sean-k-mooney | has the userdata patch been updated | |
| 11:06:24 | sean-k-mooney | if that is not updated today we should change the order or perhaps one of us can adress the nits | |
| 11:06:51 | gibi | sean-k-mooney: it was updated during the weekend | |
