Alternative virtualization approach to VMware and Xen
In the past it was quite difficult to setup a virtualization environment under Linux. Thereby Xen is a nice method to virtualize Linux instances under Linux but if you want to virtualize Windows you need virtualization feature enabled CPUs. Also the Xen setup is not really intuitive -- especially for Windows. Now the Ubuntu team have developed a frontend for KVM which simplifies the configuration process by offering a GUI for a virtual operating system setup. This feature will be available in the upcoming Hardy Heron (Ubuntu 8.04) release.
