Previous chapters described the methods of workload isolation via virtualization.
Chapter 1, “Introduction to Virtualization,” described the need for isolation and the
methods that can be used to achieve it. Chapters 2 through 6 detailed the features
of several virtualization implementations, particularly those provided by Oracle
Solaris 10 or that can host Solaris 10 guests. Chapter 7, “Choosing a Virtualization
Technology,” offered a strategy for choosing one or more of those technologies in a
particular situation.
This chapter demonstrates the use of these virtualization solutions with real-
world examples. Each example describes a goal and details the steps you can use
to replicate the example. The features used in these examples were discussed in
previous chapters; this chapter combines them in interesting ways.
A basic requirement for Dynamic Domains is the ability to create new operating
environments for new services with no detrimental effect on end users or other
applications. Moving existing resources to new domains, or adding new hardware
to the system that can later be used to create new domains, accomplishes this goal.
Although adding hardware makes creating new domains easier, reallocating or
reconfiguring existing boards can achieve the same goal with a little preplanning
effort.
The discussion here assumes that you have reviewed Chapter 2, “Hard
Partitioning: Dynamic Domains,” before you read this example. Also note that
