Hello, I am trying to achieve passthrough for Jellyfin docker container runing on a VM

My minipc is:

https://www.amazon.es/dp/B0DW92WJN7

With: Twin Lake-N150

Proxmox VE:

Code: 
Linux minipc 6.5.13-5-pve #1 SMP PREEMPT_DYNAMIC PMX 6.5.13-5 (2024-04-05T11:03Z) x86_64

root@minipc:~# uname -a

Linux minipc 6.5.13-5-pve #1 SMP PREEMPT_DYNAMIC PMX 6.5.13-5 (2024-04-05T11:03Z) x86_64 GNU/Linux

So I set up the IOMMU and blacklist I915 driver:

Code: 
root@minipc:~# cat /etc/modprobe.d/blacklist.conf

blacklist i915

root@minipc:~#


GRUB_CMDLINE_LINUX_DEFAULT="quiet intel_iommu=on iommu=pt pcie_acs_override=downstream,multifunction video=efifbff video=vesaff vfio_iommu_type1.allow_unsafe_interrupts=1 kvm.ignore_msrs=1 modprobe.blacklist=i915,radeon,nouveau,nvidia,nvidiafb,nvidia-gpu"
Then:

Code: 
root@minipc:~# update-grub

Why are you using such and old version of Proxmox with a fairly new CPU? First option must be to get the Proxmox up to date, I suggest bring it up to ver 8.4 (as 9.0 is having other issues with passthrough).
Then you have a load of unnecessary options in the grub command line. Find a passthrough guide specific to the N150 and remove everything else.

Hello, some forums supported that old kernel worked well, I tried also several times with latest Proxmox version, same result
