"Virtual Linux is accomplished through many techniques,
ranging from emulation to platform to OS virtualization. Indeed,
Linux is a unique operating system in its breadth of virtualization
solutions that are available. In this article, we'll explore the
various ways that virtualization is achieved and then review the
various solutions provided through virtual Linux.
"When we talk about virtualization solutions, we tend to talk
about specific products offered by specific companies. But when we
talk about virtualization solutions with Linux, we instead talk
about a rich and diverse open source ecosystem.
"Linux supports a variety of virtualization platforms (covering
the spectrum of techniques) as well as the elements that create a
complete solution. In this article, we'll start with a short
discussion of virtualization and then dig down into the rich set of
virtualization techniques that you'll find with Linux.
"Short Introduction to Virtualization
"There are many types of virtualization, but in this article
we'll focus primarily on what's known as hardware virtualization.
This type of virtualization abstracts the software environment from
the underlying hardware platform. We'll also explore operating
system virtualization, which is another area where Linux
