Virtual Testing - Xen Vs. KVM

Filed under
Software

Some of you might know that I use virtualization for quite some time already, usually to test other OSs and the development of EasyLFS without having to leave my working-environment, and without having to have a free partition.

On my PC I use KVM, as the AMD64 X2 in that box has support for hardware-virtualization, on the notebook I use QEmu together with KQEmu, as the Intel Core Duo lacks that support. So, more or less I'm working in the same environment, except that on my PC I get better performance thanks to the virualization-support in the CPU.

Since both of those solutions use full virtualization the whole hardware is emulated, which cuts down the performance.

Fedora, and probably many current distros include packages for Xen in their repositories. So I thought it might be a good idea to try out a new way to virtualize systems.

Ryzen 7 2700X CPUFreq Scaling Governor Benchmarks On Ubuntu Linux

With this week's Ryzen 5 2600X + Ryzen 7 2700X benchmarks some thought the CPUFreq scaling driver or rather its governors may have been limiting the performance of these Zen+ CPUs, so I ran some additional benchmarks this weekend. Those launch-day Ryzen 5 2600X / Ryzen 7 2700X Ubuntu Linux benchmarks were using the "performance" governor, but some have alleged that the performance governor may now actually hurt AMD systems... Ondemand, of course, is the default CPUFreq governor on Ubuntu and most other Linux distributions. Some also have said the "schedutil" governor that makes use of the kernel's scheduler utilization data may do better on AMD. So I ran some extra benchmarks while changing between CPUFreq's ondemand (default), performance (normally the best for performance, and what was used in our CPU tests), schedutil (the newest option), and powersave (if you really just care about conserving power).
