Hi, I updated my proxmox cluster today, to version 8.0.3 the update went through smoothly without issues.

But after rebooting on one of the servers, two of my virtual machines will not startup. seeing as they are missing the gpu that i had configured for passthrough earlier. So the setup was working on the latest 7.*.* version but stopped working after the update.

When i run "lspci" on the proxmox server I only get the builtin graphics adapter and not the tesla k80 gpu. I have verified that no changes have been made to the config files and i did do update-grub... but It seems like the gpu is not available, could it be due to the kernel update?

Found the following in the wiki... I knew i should have read it before upgrading... :D

NVIDIA vGPU Compatibility​

If you are using NVIDIA's GRID/vGPU technology, its driver must be compatible with the kernel you are using. The current (June 2023) latest version (NVIDIA GRID 15.2, driver version 525.105.14) of their vGPU host driver is not compatible with kernel versions above 6.0, but Proxmox VE 8.0 ships with at least 6.2.

This means that you will not be able to use NVIDIA vGPU functionality on Proxmox VE 8 until NVIDIA updates its driver to be compatible with newer kernels. Since NVIDIA's vGPU drivers still support 5.15 and Proxmox VE 7 is maintained until July 2024, we recommend continuing to use Proxmox VE 7.4 for now if you rely on NVIDIA's vGPU technology.

Changing the kernel version with proxmox-boot-tool kernel pin 5.13.19-6-pve --next-boot and rebooting would not make the Nvidia card available when running lspci -nn | grep 'NVIDIA' hmm wounder what it could be... :)
