The downside is higher energy consumption. Thus, I force CPU governor setting to “ performance” on the host, while the virtual machine is running. Unfortunately does the boost trigger from within a virtual machine not work consistent in my tests. When the CPU requires a boost for a process it will be allowed, in other cases it saves energy. Right after your Host system has booted, the CPU governor settings are usually set to “ on demand“. Host OS Optimization CPU Governor Settings

Software Components The Ubuntu hostĪttention! A known bug for libvirt and Windows 10 1903: Do not use 6ch/9ch audio devices in the virtual machine, as it creates awful stuttering and performance loss. BIOS versions up to (and including) 4406 are working.

CPU: AMD Ryzen 7 1800x (8 Core RAM: 32GB DDR4 RAM Mainboard: ASUS Prime x370 pro (BIOS version 4207)Īttention! The ASUS Prime x370 pro BIOS versions for RYZEN 3000-series support (up to current latest version 5220 and further), will break a PCI passthrough setup. I will try to mark these settings throughout the article. This means, some optimizations are especially (or only) relevant to Ryzen CPUs, while others are relevant to any system. I am using an AMD Ryzen platform for my GPU passthrough setup. The following chapters will give you some optimization tips for Host, Guest and hopefully some insights behind the picked libvirt settings. I reached the better gaming experience on a virtual machine with i440fx, Windconfiguration. I have forged two libvirt XML files during the tests. Whereas 1 is more important than 2 is more important than 3 and so on. Compatibility – don’t get banned, work fluently with anti-cheat tools etc. Performance – more is better, gaming performance is measured in frames per second (fps). Consistency – no freezes and/or stuttering should. Input lag – the smallest possible input latency is crucial for gaming. Instead of testing the performance with the Superpossition demo (measuring FPS only), I used three games to measure my progress.Īs the previous tests had shown, FPS alone are no reliable performance measurement in a virtual gaming environment. Additionally, even when I had one game running smoothly it was not guaranteed that others were not stuttering. Unfortunately, after several hours of testing I had to learn that those two categories weren’t enough to guarantee a decent gaming experience. I started benchmarking several setups (found on level1tech, reddit and the arch wiki) using Superpossition Demo to compare perfomance results, and LatencyMon 6.70 in order to measure the input lag. 
Especially since my main focus are demanding online multiplayer games.
In order to optimize the user experience for virtualized gaming, I started to pursue low latency and high performance.
