About Virtual Machines...
Each virtual machine on this website has been prepared using VMware Player technology. Most probably You will ask, why not VirtualBox or KVM ? The answer is short and simple - I`m familiar with that software. It doesnt mean that VirtualBox, KVM or other software are bad solution for virtualization - this is my choice. Some of virtual machines include GUI (mostly Gnome,KDE) and some of them are minimal installations (without GUI - only Unix/Linux system core).
