User mode linux book review,
This review is from: User Mode Linux (Paperback)
User Mode Linux (UML) is one of several virtual operating system technologies offered today. Most of these technologies emulate a physical piece of hardware. On that hardware, an operating system of choice can be loaded. UML is different in that instead of creating a virtual piece of hardware, UML creates a virtual operating system.
ABOUT THE BOOK
The book consists of thirteen chapters. The first few chapters are a good overview of UML, covering the basics of creating and accessing a virtual instance of a linux operating system. The middle chapters go deeper into UML configuration, covering network configurations, multiple network interfaces and managing all of these virtual operating systems from the central host. The final chapters cover more advanced topics, compiling UML from source, performance tuning considerations, and examples of different ways to use UML. There is even a section on how to build a cluster of virtual linux servers using Oracle's ocfs2. An extremely interesting idea for companies or groups who would like to try out a cluster configuration without having to make a large investment in hardware.
I found this book interesting and filled with good information. It helps that the author of the book is also the creator of UML. It was nice to see a lot of information on not only how to do something, but also the reasons why things were done they way they were. I would recommend the book for anyone interested in virtualization technology in the open source arena.
There is not a lot of comparison to all of the other similar technologies like Vmware or Xen. I would not recommend this book to someone wanting to choose between the different technologies.
