This problem happens because unraid is trying to steal the device from the VM. You need to blacklist the device from unraid as a temporary solution.

The best solution to this problem is to get a PCIE usb card and passthrough the whole thing to your VM so unraid won't steal it.

The problem:

Unknown PCI Header type 127.
Cause, according to SpaceInvaderOne, the reason this happens is when GPU is abruptly shutdown, the only way to fix this is to restart the server or use his script (which works btw).

However, the problem remains when we run the VM and gives the same message again.

Possible Solutions in Append line:

The next problem you'll encounter is if you put your GPU + Audio as your primary GPU and Audio, and run the VM you'll probably get a BLACK SCREEN. type this in the terminal dmesg | grep -i vfio after running the VM and you should probably get the following below :

The solution, when you create a VM, only put the Primary Graphics Card, NO SOUND CARD, and it should run without a black screen and should boot properly. This may be a quirk of the consumer cards, but at least it should work.
Warning: You need to have an iGPU on top of your primary GPU. I tried running unraid with one GPU, it will still give you a black screen. Make sure Unraid uses your iGPU or something else. Unraid must absolutely not use your VM GPU.
