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.
