The Xen hypervisor, a powerful open source industry standard for virtualization, offers a powerful, efficient, and secure feature set for virtualization of x86, x86_64, IA64, ARM, and other CPU architectures. It supports a wide range of guest operating systems including Windows, Linux, Solaris, and various versions of the BSD operating systems. In order to run Xen, you will need to install and boot from a Xen dom0 kernel. Check README.dom0 (in docs/dom0) for more information on how to do that. mbootpack is an optional dependency. Since booting a Xen kernel with LILO is not supported by default we have to use GRUB; alternatively, you can use mbootpack to create a LILO compatible kernel. The Xen hypervisor no longer builds on x86 32 bit operating systems. See README.SLACKWARE (which is also installed with the package docs) for setup, configuration, and usage hints.
