![]() Once your OS is installed, you'll need to passthrough a mouse and keyboard, which will then be unusable by the guest. Two sets of keyboard/mice, or a KVM switch.Many people have setup VGA passthrough without full ACS support- but having it means one less thing to worry about. With my CPU and X99A mainboard combo, every single PCI device is inside of its own IOMMU group, without the need for quirks/patches. If you have a CPU that does not fully support ACS and your IOMMU groupings are less than ideal, workarounds can be done. Your CPU should fully support ACS if you don't want to worry about IOMMU groupings.The graphics card you plan to passthrough should have a UEFI or Hybrid BIOS. ![]() Your host operating system should be installed in UEFI mode, and your machine set to boot via UEFI.Kernel should be 4.1 or newer otherwise you may need to apply various workarounds.Example from the PDF manual for my motherboard, which I checked before purchasing. When buying new hardware, check the motherboard's User Manual, which can typically be found on the product page on the manufacturer's website. Motherboard must support VT-x and VT-d (or AMD equivalents).CPU must support Directed I/O (VT-d for Intel, generically known as IOMMU).CPU must support virtualization extensions (VT-x for Intel).This should not be considered an exhaustive guide- I've provided links to additional resources at the end of this document in case you get stuck, or have needs that differed from mine. There are a lot of places where things can go wrong, and I'll try to point those out. I have used libvirt to manage things, and instructions for using virt-manager to perform most tasks have been provided (some configuration, such as CPU pinning or using raw block storage, is not possible via virt-manager). This write-up details my experience in setting up a Windows 10 guest to run on an Ubuntu 16.04 host. My major issue now is that I need a bigger desk to stick more monitors on ) I have never liked dual-booting, and using Windows as my primary OS is not really an option, as far as I'm concerned. ![]() linux / virtualization / kvm / vga passthroughĪfter many months of research and reading through various articles detailing VGA passthrough builds (such as here, here, and here), I finally decided to upgrade my machine- with PCI passthrough being a primary objective of the new build. ![]() ![]() VGA Passthrough with OVMF+VFIO on Ubuntu 16.04 ![]()
