I’m new to this Forum so please be gentle
So what’s the Problem here? I followed the “Wendells” Guide VFIO in 2019 using PopOS 18.04 and everything seems to fit until I reach the Point of starting my VM after the GPU is attached. At first it starts with no Output on the second Monitor, after I stop the VM (forced shutdown due to no VGA Output) the Virtual Machine Manager throws in “Unknown PCI header type ‘127’”. This can only be solved by restarting the Host. But the Problem of no Output remains. The NVIDIA GPU (Gainward 960GTX Phantom 4GB) is claimed by “vfio-pci” and only the second GPU (a very old HD3450) is used by GNOME. The NVIDIA GPU and it’s Audio Device are in the only Devices that are in IOMMU Group 15, so that seems also to work.
Did anyone encounter this or has a solution?
