Preface “The search for truth is more precious than its possession.” — Albert Einstein This book describes how to roll your own Linux virtual servers on IBM® System z hardware under z/VM®. It adopts a cookbook format that provides a concise, repeatable set of procedures for installing and configuring z/VM in an LPAR and then installing and customizing Linux. You need an IBM System z logical partition (LPAR) with associated resources, z/VM 6.1 media, and a Linux distribution. This book assumes that you have a general familiarity with System z technology and terminology. It does not assume an in-depth understanding of z/VM and Linux. It is written for those who want to get a quick start with z/VM and Linux on the mainframe. Chapters and Appendices The remaining chapters and appendices in this book are summarized in the following list: ► Chapter 1, “Introduction to z/VM and Linux” on page 1 gives a brief introduction of the book. ► Chapter 2, “Planning” on page 7 describes how to plan hardware, software and networking resources. It discusses DASD labeling conventions used in the book and password planning. Sample worksheets are provided for the examples used in the book, as are blank copies for your use. ► Chapter 3, “Configuring a desktop machine” on page 19 describes how to set up Windows® desktops. Specifically, the following tools are discussed: – How to get and set up PuTTY: a commonly used SSH client – How to get and set up a VNC client: a tool for running graphical applications – 3270 emulator applications ► Chapter 4, “Installing and configuring z/VM” on page 27 shows how to install and configure z/VM. This is where you roll up your sleeves and start to work. ► Chapter 5, “Servicing z/VM” on page 71 describes how to apply service to z/VM both in the form of Programming Temporary Fixes (PTFs) and Recommended Service Upgrades (RSUs). ► Chapter 6, “Configuring an NFS/FTP server” on page 93, explains how to set up a temporary NFS server on a Linux PC for the purpose of installing the first two Linux images. After the cloner Linux is installed, you can copy the Linux install tree to it and retire the Linux PC server. ► Chapter 7, “Installing RHEL 6 on the cloner” on page 101, describes how to install and configure two Linux images onto the first Linux user ID: the golden image, which it is cloned from, and the cloner, which does the cloning among other tasks. ► Chapter 8, “Installing and configuring the golden image” on page 129, describes how to install and configure two Linux images onto the first Linux user ID: the golden image, which it is cloned from, and the cloner, which does the cloning among other tasks. © Copyright IBM Corp. 2010.
