10.7.3.4. ...booting other operating systems?
It is possible to install other Linux distributions and (soon) other operating systems into guest domains, but they must be installed manually; Fedora's Xen installer only works with Fedora Core at this point. For information on installing other Xen guests, see the XenSource web site ( http://www.xensource.com ) and the documentation for the Xen guest you wish to install.
Microsoft Windows and other unmodified operating systems can be used as Xen guests only with hardware virtualization support.
