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. COURSE CONTENT:   •    Xen and virtualisation overview •    What are virtual machines, virtualisation, paravirtualisation? •    Installation of Xen on RHEL5 •    Use of yum and installing Xen from source •    Creation of Xen virtual machines •    Installing Kubuntu, NetBSD, Solaris & Windows as guests •    Xen management tools •    Use of xm, XenMan & virt-manager •    Xen networking •    Configuring bridged and routed networking •    Xen storage options •    Storing options including UFS, LVM & NFS •    Encrypting guest filesystems •    Securing the guest operating systems with encryption •    Migration of Xen instances •    Saving and restoring domains.
