https://forum.proxmox.com/threads/another-solution-for-passthrough-intel-igpu.176959/ check this, and when you passthrough igpu, make sure your VM display set to none or it will hang.

ok, but for backing up VM or LXC, why dont you use PBS? https://www.proxmox.com/en/products/proxmox-backup-server/overview you can install PBS inside another windows machine running Hyper-V, or unofficially you can install inside a raspberry pi5b (which what i am doing now).

just curious, why you need to back up those setting periodically? normally those are just default, or even a onetime setting and forgot it thing right? isn't one time backup after modification should be more than good enough?

previously i shared a solution that to passthrough iGPU to linux vm with working HDMI output, using i915_vbt file method from host machine. https://forum.proxmox.com/threads/solution-intel-igpu-passthrough-to-linux-vm-but-failed-with-kernel-6-10-onward.153659/ yesterday i found another...

blacklisting driver should not crash your proxmox, must be something else. since it is a fresh install you should try again.

in my case i use nomachine, and nomachine can utilize the GPU for hardware encoding, however it cannot stretch to 2 monitor afaik. i have an iGPU passthrough to a Linux vm, and two nvidia passthrough to two windows 11, all with nomachine and able to utilize the H264 hardware encoding with the gpu.

install the VM as you like, connect to the VM using VNC, or nomachine, or anydesk etc, make it full screen on your host.

set the display to none, and make sure you copy the i915_vbt. display and igpu passthrough does not play well together in latest kernel.

i have this same as yours /etc/modprobe.d/blacklist-nvidia.conf blacklist nouveau blacklist nvidia blacklist nvidiafb blacklist rivafb blacklist snd_hda_intel

nvidia card is easy to passthrough without additional setting, i am passing through it to a windows 11 VM since PVE8 and now PVE9. simply adding it to your VM should work just fine.

did you by any chance blacklisted i915 driver? another potential problem is to check your bios, some motherboard default setting will disable igpu when a PCIE GPU is installed.

for those using latest kernel in Linux VM and failed with iGPU passthrough, read here https://forum.proxmox.com/threads/proxmox-9-gpu-pass-through.169151/post-787947 you need to get the i915_vbt https://gitlab.freedesktop.org/drm/i915/kernel/-/issues/12106

i am not using AMD so not sure if what i did for intel can apply for AMD, or not. below was my step https://forum.proxmox.com/threads/alderlake-direct-passthrough-to-linux-vm-is-working-with-hdmi-output.138049 although when i wrote it was using 12th gen alderlake, but i confirm it is working...

could be AMD specific, I have 2 nvidias and 1 intel igpu, all passthrough with working HDMI and audio output.

I think you might be bump in to this https://gitlab.freedesktop.org/drm/i915/kernel/-/issues/12106 you need to manually solve it follow that discussion, and still latest 6.12 kernel still having this issues.
