HowtoForge website published tutorial that provides step-by-step instructions on how to install Xen 3.3.1 on a Debian Etch (4.0) system.

Xen allows anyone to create guest OS (Unix operating systems like Linux and FreeBSD), so called "virtual machines" or domUs, under a host OS (dom0). With Xen we can separate applications into different VMs which are fully independent from each other while residing on the same physical machine.

The HowtoForge's user "Falko" says that they use Debian Etch system with the hostname server1.example.com and the IP address 192.168.0.100 as the host system (dom0) in the tutorial. They also use Debian Etch for the virtual machines (domU) as well. The user says that the guide explains how to set up image-based virtual machines and LVM-based virtual machines.

VMware announced the release of Fusion 2.0.2, an update to company's virtualization software for Mac OS X.

VMware Fusion enables Macs that use Intel processors to run other OS and their application software as "virtual machines", rather than having to reboot. The technology allows anyone to run Mac OS X and Mac apps alongside Windows, Linux and other OS that work on Intel hardware. It also operates on Apple’s Xserve systems as an enterprise server virtualization product.

The new version 2.0.2 allows its users to import virtual machines created using a competitor product — Parallels Desktop 4. The update supports Parallels Server as well.

Fusion 2.0.2 makes also possible Leopard Server to be be virtualized and this mounts a .DMG (disk image) from a virtual machine. An issue with running Mac OS X 10.5.6-based virtual machines has been fixed. Now all the issues that Mac users experienced when installing the Leopard Server virtual machine on new MacBooks, MacBook Pros and MacBook Air are resolved.
