Xenoppix

Xenoppix is a customized Knoppix disk that includes Xen 3.0. This is a great way to test out Xen without having to install it to a hard drive. If you have an Intel CPU that supports Virtualization Technology, you can actually run an unmodified operating system with it. Knoppix is an ideal platform to use as a host system, as it provides excellent automatic detection of system hardware. I suspect (although have been unable to confirm) that it should be possible to use Xenoppix to run a Windows XP guest operating system. I wish I had an Intel VT CPU to confirm first-hand. The newest Intel Macs have VT support, so theoretically one should be able to use Xenoppix on it to run Windows XP and other operating systems.
