The extracted one from BIOS update needs to be patched against OVMF firmware and the other vBIOS needs to exist inside the VM next to a fake battery. We extract one version of it from the BIOS update file and another one with the active Nvidia GPU from within the system. The laptop comes with 3 different versions of vBIOS. This Intel GPU will do nothing more then allow the driver to be installed. But due to Intel GVT-g technology, we will pass a virtualized GPU to it. While we only expect the powerful Nvidia GPU to work inside the VM, it needs both GPUs to be passed into the VM. Most of them are related to decisions by Nvidia. There are a number of obstacles in order to successfully pass the Nvidia GPU into a Windows guest system and make it work with the Nvidia drivers.

3.3.3 Let VBiosFinder extract the vBIOS.

3.2 Extract activated vBIOS from system.

There are several ways to accomplish this with some of them having issues here and there. Switching the Nvidia GPU between host and guest is known to work. For this reason it will not include instructions for audio passthrough or dynamic switching of the Nvidia GPU between host and guest and assume the Nvidia GPU to be soley for QEMU. Since it is complicated enough already, this guide will only cover a basic setup for Thinkpad P53 series running Gentoo as host on the laptop display and Windows 10 as guest on a monitor connected to the HDMI port.

The external HDMI port is directly wired to the Nvidia GPU while the internal Intel GPU will only output to the laptop display. In case of the Thinkpad P53 (and maybe other high end Thinkpads) it does work well due to the muxed GPU hardware and the decent IOMMU layout. It is also known as IOMMU or VFIO and the best way to get a virtual machine running with GPU passthrough is by using QEMU. In most cases this will be used for gaming or anything that requires GPU performance. It allows you to run a virtual machine with Linux or Windows 10+ with near native performance. GPU passthrough is a technology that allows the Linux kernel to directly present an internal PCI GPU to a virtual machine.
