Product Description

Creating a virtual network allows you to maximize the use of your servers. Virtualization: From the Desktop to the Enterprise is the first book of its kind to demonstrate how to manage all aspects of virtualization across an enterprise. (Other books focus only on singular aspects of virtualization, without delving into the interrelationships of the technologies.)

This book promises to cover all aspects of virtualization, including virtual machines, virtual file systems, virtual storage solutions, and clustering, enabling you to understand which technologies are right for your particular environment. Furthermore, the book covers both Microsoft and Linux environments.

Virtualization: From the Desktop to the Enterprise (Books for Professionals by Professionals) Review

I am an uncertified VMware integrator. I would take the certification test, but you have to go through official training first (quite expensive). I am generally apprehensive about buying a computer book that gets a really low review from what seems to be a credible sources. But I took a chance and bought Virtualization: From the Desktop to the Enterprise.

Basically, I would like to share with you that this book is darn good and it covers virtualization applications, like ESX Server and Virtual Server really well. Moreover, the book does a really good job of taking you through virtual file systems, clustering, and virtual machine backups on a budget. One thing I noticed about the book is that it is pretty darn vendor neutral and will get you up and running in not time.

After reading the book, I wanted to share with you what I found out about the one-star review.

Allegation in Review:

"-It says ESX [runs on the] bare metal but then lists the size requirements to install it on Linux and Windows [which is impossible, if it runs on the bare metal]"

What I found out:

On page 154, the text states that "ESX server directly communicates with your system's hardware and is said to run on the metal." Within two paragraphs, hardware requirements are discussed. No mention of Linux or Windows is made. Moreover, the first paragraph in the section under "Installing VMware ESX Server" (p.154) states that ESX Server is "a stand-alone product, which means an operating system isn't required to host the ESX Server virtualization application". No where in the text are the requirements of ESX server conflated with GSX server which installs on top of Linux and Windows. This statement by the reviewer is false.

Allegation in Review:

"-It totally mixes the concepts of SC swap with vmkernel swap by applying sizing recommendations for SC swap to vmkernel swap."

What I found out:

The book discusses swap file configuration location for the Service Console (SC) on page 167: no mention of sizing requirements is made. As noted in the chapter introduction (Chapter 5), the book is taking a "step-by-step approach when showing how to install each virtualization application". Moreover, on page 154, the book discusses that "two configuration scenarios [will be covered:] the first scenario covers what might be involved with a troubled installation, and the second scenario details what you'll experience with a typical configuration." If the reader of this review actually read the book and was performing a troubled install as noted in the introduction, the information on page 168 regarding swap files is about the current Swap Configuration screens. The text makes no distinction between the vmkernel swap file and the SC swap file.

Allegation in Review:

"-It talks about USB on ESX [which is currently not supported] "

What I found out:

The book does cover the configuration and use of USB devices and the book acknowledges that it is currently not supported. The book, beginning on page 185, provides detailed steps to make USB function. In addition, on page 185, the book states "VMware fully documents disabling USB support" and on page 187, the book discusses that "USB devices aren't supported within ESX Server...and VMware briefly explains this in Answer ID 1015 in its knowledge base." Despite that USB is not "officially" supported, it does work and enabling USB is clearly documented by VMware in its knowledge base. The statement by the reviewer is a misrepresentation of the text.
