Our crew walks you through their PCI Passthrough setups that let them run Windows, macOS, and distro-hop all from one Linux machine.
Forget multiple partitions, dual booting, and Hackintoshes; you can do it all with Linux and KVM.
Near-native VM performance doesn't have to be painful. You only need a few prerequisites and a little help.

- VFIO tips and tricks: IOMMU Groups, inside and out — Sometimes VFIO users are befuddled that they aren't able to separate devices between host and guest or multiple guests due to IOMMU grouping and revert to using legacy KVM device assignment, or as is the case with may VFIO-VGA users, apply the PCIe ACS override patch to avoid the problem. Let's take a moment to look at what this is really doing.
- "Error 43: Driver failed to load" on Nvidia GPUs passed to Windows VMs — Since version 337.88, Nvidia drivers on Windows check if an hypervisor is running and fail if it detects one, which results in an Error 43 in the Windows device manager. Starting with QEMU 2.5.0 and libvirt 1.3.3, the vendor_id for the hypervisor can be spoofed, which is enough to fool the Nvidia drivers into loading anyway.
- Mac OS Adds Early Support for VirtIO, Qemu - The Passthrough POST — In a new development uncovered by Qemu developer Gerd Hoffmann, Apple has apparently added early support for VirtIO and framebuffer graphics in a later Mac OS Mojave release.
- New and Improved Mac OS Tutorial, Part 1 (The Basics) - The Passthrough POST — Due to certain recent developments, It’s become clear to us that it’s necessary to update and improve our OSX VM guide. A lot’s changed since we wrote it, and rolling in those changes will make the process much more user friendly and accessible to newer VFIO users.
- Mac OS VM Guide Part 2 (GPU Passthrough and Tweaks) - The Passthrough POST — We’ve made every attempt to make this as straightforward as possible, but there’s a lot more ground to cover here than in the first part of the guide
- UGREEN USB 3.0 Sharing Switch Selector 4 Port 2 Computers Peripheral Switcher Adapter Hub for PC, Printer, Scanner, Mouse, Keyboard with One Button Swapping — This USB Switch 4 Port device allows up to 2 users to share 4 USB 3.0 peripheral devices, such as printer,scanner,mouse,keyboard or usb disk etc without the need to constantly swap cables or set up complicated network sharing software. It's a great for use at home if you have multiple PCs or Macs.
- How to setup VFIO GPU passthrough using OVMF and KVM on Arch Linux — This article will detail the steps required to passthrough your GPU to a guest VM which will in our case be a Windows 10 VM used for gaming. Yes, this is the exact same technology made popular by Linus on his LinusTechTips YouTube channel in the seven gamers, one CPU video.
