AUDIENCE:   Experienced Linux Administrators who require to utilise Xen virtualisation to host a number of operating systems. PREREQUISITES:   A good understanding of Linux, preferably under the Red Hat Enterprise Environment. 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 SolarisTM, LinuxTM, FreeBSDTM, WindowsTM and NetBSDTM. The Xen Virtualisation course is based on the open-source version of Xen using RedHat 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 Linux (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 Security Encrypting guest filesystems Securing the guest operating systems with encryption Migration of Xen instances Saving and restoring domains Live migration NT08/01
