Note that this installer script is a BETA test release. The packages used contain versions of Xen 3.0 built for i686 SMP systems (Intel Pentium Pro, Celeron, Pentium II, Pentium III, Pentium 4, Xeon; AMD Athlon, Duron). Since these packages are non-PAE (highmem4g) builds, only up to 4GB of memory is supported.
Installing Xen 3.0 using the new Xen Installer script is an ideal way to start evaluating and using Xen. It takes care of all the steps needed to install Xen 3.0 on a system with Fedora Core 4 or RedHat Enterprise Linux.
The new Xen Installer requires that you have installed Fedora Core 4 or RHEL 4.1 on your system.
