Hi,
I have a Nvidia GPU passthrough working on a VM but on the proxmox host during the boot it shows these errors and in the end I loose ability to type in the console, the cursor freezes.
Everything works by ssh but I wanted to be able to connect a monitor to the host and use the keyboard.

I have the hdmi cable connected to the nvidia gpu because if I connect to the on-board hdmi it doesn't show any image at all during boot.

some information of the configs:
Code:
/etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT="quiet intel_iommu=on video=vesafb:off,efifb:off"

/etc/modules
vfio
vfio_iommu_type1
vfio_pci
wireguard

/etc/modprobe.d/blacklist.conf
blacklist nouveau
blacklist nvidia
blacklist nvidiafb
blacklist nvidia_drm

/etc/modprobe.d/vfio.conf
options vfio-pci ids=10de:2504,10de:228

result of lspci -nnk

On the VM the Display is set to none

The system is running fine, the VM is also working with the gpu transconding for plex and jellyfin but I wanted to understand and get rid of these errors while also be able to use the monitor.

Any ideias.
Thank you.
