All, I'm very intriqued with the new Xen / Win XP guest OS functionality that should be available soon, or maybe already is. Does anyone know a url / wiki / blog that has uptodate info? What I know: To get Xen to work with a vanilla Win XP as guest OS you need support in your host OS, Xen, your CPU, and your motherboard/bios. Xen 3.0 is supposed to have the basics for the support, but I'm not positive it has actually been tested with all of the above. See http://www.planetx64.com/index.php?option=com_content&task=view&id=33&Itemid=49 Intel has released at least one CPU that supports the VT. ie. the new features required to support the above. See http://www.intel.com/products/processor/pentiumXE/index.htm My concern is this footnote: Φ Intel(r) Virtualization Technology and Intel(r) Extended Memory 64 Technology (Intel(r) EM64T) require a computer system with a processor, chipset, BIOS, enabling software and/or operating system, device drivers and applications designed for these features. Performance will vary depending on your configuration. Contact your vendor for more information. So, as expected, a MB (or computer) with VT support is also required.
