Even though the virtualization has began in the 60-ies (http://en.wikipedia.org/wiki/Virtualization), the advancements in the OS, computer capacity and especially the CPU capabilities have opened a whole slew of possibilities to the modern IT shops and especially to the SMBs.RedHat’s implementation is one of the most robust, yet prominent offerings in this area. It allows to provision such logical components as data centres, clusters, hosts, storage, networks, disks and more. And it is not limited to running only the Linux based OSes, Windows 8 or Windows Server 2012 are also supported (well, there is no possibility to accessed them via VNC yet).Virtualization is great in balancing production loads, providing HA or in scenarios as conducting a POC, temporal machines spawning or on demand scaling out/up.The chapter 2 on installing RHEV is the most important to understanding how the RedHat’s technology works.Chapter 4 – Creating Virtual Machines I expect to be the most re-visited as it will be the most often used procedure by an administrator, and I suspect is the centrepiece of the book. It covers both, creating a custom OS image or a template to be re-used.Chapter 5 – High Availability is my favourite, it was also fun to learn about live migrations, fencing and Resilient Policies, features I even did not expect exists in RedHat virtualization offering. This chapter also contains several very valid gotchas to using the HA mode effectively.Chapter 5 – Advanced Storage and Networking Features is really a showcase of the RedHat virtualization capabilities and also would be very valuable to the not so technical audience to get familiar with what it offers and how it can help deliver greater flexibility across an enterprise.Chapter 7, 8 are targeting primarily the RedHat virtualization system administrators, and it appears having superb capabilities to managing its resources and users. Chapter 8 explains how to use Quotas and assign resources.Chapter 9 makes you start mastering the CLI, as everything Linux command line is the king, as while a GUI is great, the command line offers greater productivity and most importantly – automation, but do not stop there as it is a beginning to start writing automation scripts which sooner or later would necessary.The book then naturally flows into the chapter on troubleshooting. This chapter, I deem, is absolutely making sense as many things can and undoubtedly some day bound to go awry. Make sure you read this chapter carefully, and in advance of the unforeseen.The story ends with a short, but helpful chapter on setting the storage peripherals as iSCSI, NAS and NFS. Like the others, this chapter exposes a plethora of command line commands to set everything up you may need. So it is a good idea to read it even if there are no plans to manipulate on directory management or configuring storage, after all, you never know when it may become handy.Having 178 pages in the book Pradeep Subramanian actually managed to packed quite a lot of insight and knowledge that I expect will trigger several “aha” moments in your IT life.In my opinion, overall, since it is quite tedious to install and support RedHat EV this book should be invaluable.

Bernie Ongewe Nov 14, 2014

For being such a fast-rising leader in virtualization-space, Red Hat’s documentation on the topic can be... disjointed.Thankfully, Subramanian has stepped up to give RHEV some solid treatment; from installation to maintenance and troubleshooting.Also, despite being a Red Hat employee he resists the kind of non sequitur promotion we often see.

Karthikeyan J Oct 20, 2014

I got this book couple of days back. I'm quite new to the Redhat KVM. The author has done a brilliant job of putting the concepts in a neat and concise manner.The Concepts are easy to read and understand. The coverage of the topics are well thought through.... Installation, Administration and Troubleshooting.If we can include more topics like how KVM interacts with the underlying physical hardware and other hypervisors , it will enhance the coverage of this book... But it is a great resource for a beginner and intermediate level Engineers.Keep up the good job!!!

Rodrigo Ramos Nov 13, 2014

It is a good manner to start with RHEV and its components, but, is not enought deep for complex enviromens.

G. Myers Jul 15, 2016

This very thin book proved to be of no use. I thought from a book I would get different insight on how to install and use RHEV, but the online documentation from RedHat was much more thorough and useful.
