AUDIENCE:   Experienced Linux Administrators who require to utilise Xen virtualisation to host a number of operating systems. PREREQUISITES:   A good appreciation of the target operating system. DURATION:   2 days. Hands on. OBJECTIVES:   Xen is an open-source virtualisation technology providing the ability to run multiple operating systems on one physical machine. Due to the nature of Xen, there is only a minimal loss of performance of the operating systems when compared to a native install. Several operating systems are supported including Solaris, Linux, FreeBSD, Windows and NetBSD. The Xen Virtualisation course is based on the open-source version of Xen using Enterprise Linux 5 as the host operating system. The course starts by giving an overview of virtualisation methods and continues with the installation of Xen on Enterprise Linux 5 and installation and management of various hosts operating systems.
