Kernel 6.8.12-13 and proxmox-kernel-6.14.8-2-bpo12-pve fixes vfio. Thank you guys.

Kernel 6.8.12-13 and proxmox-kernel-6.14.8-2-bpo12-pve fixes this. Thank you guys.

it should but proxmox version of the kernel breaks vfio for me :eek: I see 6.8.12-13 is out. I'll boot it just to check if it changes anything. EDIT: Yes, Kernel 6.8.12-13 and proxmox-kernel-6.14.8-2-bpo12-pve fixes vfio. Thank you guys.

Have a look at the attachment: My notes tell me: mkdir /var/lib/vz/snippets nano /var/lib/vz/snippets/200.pl chmod +x /var/lib/vz/snippets/200.pl Then as example: qm set 200 --hookscript local:snippets/200.pl or if you don't need it anymore: qm set 200 --delete hookscript or edit the...

With the latest 6.14.8 kernel I have Vfio problems. VMs that use my X710 VF will not start. (Same with 6.8.12-12, 6.8.12-11 is ok) Example: ➜ ~ qm start 100 GUEST HOOK: 100 pre-start 100 is starting, doing preparations. kvm: -device...

Oh man, nothing like that. This is just a hobby for me—100% consumer gear, single GPU setup. I wanted an all-in-one solution: a router, a NAS, and “unlimited” OS flexibility, so I can switch between them at will. My GPU is mainly for actual image output for my "Desktop VM" of the moment. As for...

Anyone else?

Which kernel are you using on your host? If it's the 6.8.12-12, try with the 6.8.12-11. Same if you are with the 6.14.8, try the 6.14.5.

OH !! ok ok :D Glad I could help.

I would personally use OVMF + Q35. Rombar + pci-express and cpu set to host. These have been my miracle settings so far. EDIT: Lol, I did tell you it would seem odd, didn’t I? You never know until you try it!

I'm positive it is needed if you want to control the idle power when the gpu is not in usage by any VM, but 10W idle ? :D on a 5090 lol ? Nope :D Should be around 30W. A bit less than 10W is what the 5060 TI used, the 5070 TI about 18W. The 5090 should be around 30W idle. So yes, loading the...

You can. I did it myself.

I had your "Unable to change power state from D3cold to D0, device inaccessible" when I was lucky and a "automatic" hard motherboard reset most of the times. To make it bearable, I had to unload the nvidia driver inside the VM before shutdown. All fixed after the firmware update. My previous...

Install the nvidia driver, let it initialise the gpu(s), then unbind the driver for the card you want to use and start the vm. Proxmox will bind vfio for you. What do you have to lose ? I had your problem in the past and no more. The nvidia firmware is literally a requirement or the card(s) in...

This is gonna seam odd to you since the following utility is supposedly for the 5060 and 5060 TI but using windows try to run this nvidia utility on your card and see if it has firmware up to date. The utility is for the 5000 Series. I had to update my 5070 TI for it to start to work correctly...

Yes and the funny thing is that the update utility is labelled for the 5060 and 5060 TI when in fact you can run it on any 5000 Series (did not try on older). I exchanged my 5060 TI for a 5070 TI and I had to run the utility and update the card firmware for it to start to work correctly.

I'm not alone :D I'm on the same boat but with a modern intel system. Intel 13900, z790 chipset, X710 nic. https://forum.proxmox.com/threads/regression-cannot-start-vms-with-kernel-6-8-12-12-pve-and-6-14-8-1-bpo12-pve-and-pci-passthrough-sr-iov-x710-vf.168514/

Ok. Proxmox 6.8.12-11 works fine but 6.8.12-12 fails. There's definitely some regression for me on 6.8.12-12 and 6.14.8-1-bpo12-pve.

I just compiled kernel 6.15.6 and it's working fine. I'm really scratching my head.

With the Proxmox kernels 6.14.4-1-pve, 6.14.5-1-bpo12-pve, and my self-compiled 6.14.8 kernel, I can successfully start any VM that uses PCI passthrough for a VF from my Intel X710 NIC. However, with the 6.14.8-1-bpo12-pve kernel, any VM that attempts to use PCI passthrough for a VF from the...
