Chapter 1.
Introduction
The first edition of the <strong>Advanced</strong> <strong>POWER</strong> <strong>Virtualization</strong> on IBM System p5,
SG24-7940 was published over two years ago. Since that time, IBM and its
partners have gained considerable experience with the technology and have
received feedback from clients on how they are using virtualization in the field.
This third edition takes the lessons learned over the past year to build on the
foundation work of the first version of the redbook. The result is the IBM Redbook
in your hands, a comprehensive re-write of the initial work, and an enhancement
of the second edition.
This publication targets virtualization novices as well as those that have already
experimented with the technology. It is written in a hands-on style to encourage
you to get started. This latest edition enriches the basic virtualization scenarios of
the first and extends them to include some of the more advanced configurations,
in particular for improving availability, using the Partition Load Manager,
performing administration tasks, and monitoring system resources.
The remainder of this chapter provides a short overview of the key virtualization
technologies. Chapter 3, “Setting up the Virtual I/O Server: the basics” on
page 117 covers the foundation technologies in detail as well as the new Virtual
I/O Server Version 1.3 features. An understanding of this chapter is required for
the remainder of the book. Chapter 4, “Setting up virtual I/O: advanced” on
page 181 covers initial partition configurations while Chapter 4, “Setting up
virtual I/O: advanced” on page 181 looks at more complex setups such as
SAN-attached storage and multiple Virtual I/O Servers. Chapter 5, “System
