XEN Virtualisation

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.
