Setting the Video OpRom loader to None in the BIOSĬompile kernel with no framebuffer, vga console, vga arbiter and basically no graphics at allīoot the kernel directly as EFI application without GRUB2 or any bootloader in between which could mask the VBIOS on the iGPU I already tried to completely isolate the iGPU from the whole boot process and it reliably prevents the screen from showing anything at all, including The guest always complains, that it can't find the VBIOS. Or vfio pci 0000:00:02.0: "Video device with shadowed ROM" at ![]() ![]() I only get a black screen and error messages in dmesg such as: vfio-pci 0000:00:02.0: vfio_ecap_init: hiding ecap 703.013256] vfio-pci 0000:00:02.0: Invalid PCI ROM header signature: expecting 0xaa55, got 0xffff I tried different setups but it doesn't work. I'm trying to get OVMF PCIe passthrough of my iGPU on my laptop running, also called GVT-d for Intel GPUs, such that the VM controls the display of my laptop.
