You MUST turn off Secure Boot in the VM! Or some drivers won't work!.There are no steps that specifically require UEFI boot mode.

My VM boots in UEFI (OVMF) mode, but theoretically, this guide will also work with BIOS (SeaBIOS) mode.

Set up a virtual machine of Windows 10 or Windows 11 with Libvirt (Virt-Manager). Theoretically, Secure Boot may cause limitations on the PCIe passthrough functionality.

It's recommended to turn off Secure Boot, but you likely did it anyway since you installed Linux.

Most of the steps, however, should still apply to other Linux distros.

(2023-05) My operating system is now NixOS while writing this update.

(2022-01) My operating system is Arch Linux, with the latest updates.

: The PCIe power-saving patch isn't effective.īefore following steps in this post, you need to prepare:Ī laptop with the Optimus MUXed architecture.

: Update some contents for new version of Looking Glass B6.

I am finally able to create a GPU passthrough setup that works long-term. Since there is a way to make the virtual machine aware of a "monitor on the dedicated GPU", most functionalities work normally. The HDMI output port on this laptop is directly connected to its NVIDIA dedicated graphics card, or in other words, it has an Optimus MUXed architecture.

Therefore, severe limitations exist for that setup, and I eventually gave up on it.īut now, I've purchased a new laptop. But since that laptop has an Optimus MUXless architecture (as mentioned in that post), its dedicated GPU doesn't have output ports, and the integrated GPU is in charge of all the displays. A year ago, to simultaneously browse webpages and write codes on my Arch Linux installation and use Windows to run tasks infeasible on Linux (such as gaming), I tried GPU passthrough on my Lenovo R720 gaming laptop.
