Now, for each individual disk, you will need to assign it one of the IO threads you just created. Add a line, replacing '4' with the number of virtual disks you're creating: Virt-manager does not have a way to enable them, so we must use sudo virsh edit. IOthreads were the biggest boost to performance they create a separate thread for each block device that is separate form QEMU itself. raw files or LVM, VirtIO drivers, cache=none, io=native, and enabling IOthreads. After extensive testing, I found that the best combination of IO devices is using. Maximizing IO performance took me several days of reading a huge amount of resources from dozens of people who admin KVM/QEMU systems professionally and are much smarter than I am. Recommendation: Maximizing IO Performance I can absolutely NOT recommend Ubuntu for VGA passthrough simply because it is significantly different from Fedora and thus works weirdly with virt-manager/libvirt The creators of libvirt/virt-manager (RedHat) also write Fedora, thus integration is seamless. For a user who has not used either, I would recommend Fedora. As a longtime Arch user, I picked the former. When doing VGA passthrough, two Linux distributions are relatively popular: Arch Linux and Fedora. On that note, if you can afford it, I would go with an i7 over an i5, simply because of hyperthreading, which will be of a significant benefit when running a virtual machine, especially with modern QEMU threading and CPU pinning. 8GB is enough for a modern computer, but remember, you will essentially be running two operating systems at the same time. You can also just buy a cheap PCI USB card see the 'Passing through USB devices' section.

Motherboards which have tons of USB ports usually use multiple USB Buses, one of which you can pass through to the guest, simplifying the USB problem by a significant amount. First, get a motherboard with a ton of USB ports. If you're buying new hardware, I'd recommend a couple things. I ended up going with an i5-6600k, Asus Z170-Pro, 16GB DDR4 RAM, and an XFX R9 390.

I created this build with the explicit intent of overclocking and VGA passthrough. Over time, some specific guides and wiki pages ended up being incredibly useful: As always, the Arch Wiki Alex Williamson's guide is excellent RedHat KVM Tuning Guide Problem: Bridged Networking with GNOME/NetworkManager Recommendation: Maximizing CPU/Memory Performance This information is not presented as a basics guide I'm assuming you're already experienced enough to be reasonably attempting VGA passthrough. I will cover what I did right, what I did wrong, and solutions to common issues.

The goal of this guide is NOT to cover material covered in generic guides on setting up VGA passthrough, but rather to cover problems, optimizations, and tweaks to fill in the gaps between these guides and a full speed Windows virtual machine.

#QEMU VGA PASSTHROUGH NON UEFI PC#

I made a PC build with this explicit purpose in mind and have spent the last week building the computer, installing Linux and the VM, and optimizing my system to reach the peak of what this build can put out.

#QEMU VGA PASSTHROUGH NON UEFI WINDOWS 10#

Just to preface what will be an extremely long post, I have successfully created and optimized a Windows 10 virtual machine with the sole intent of playing games.
