Packed with practical advice, this hands-on guide provides valuable information you need to most effectively optimize and manage the XenServer open source virtualization platform. Whether you run a modest installation of a few blades or multiple global enterprise datacenters, this book focuses on the most critical issues you’re likely to encounter when designing a XenServer deployment and helps you handle day-to-day management tasks.
Tim Mackey and J.K. Benedict from Citrix Systems, the company that manages XenServer, show you how to design a deployment through best practices, deployment blueprints, and installation guidelines. The book’s second part features concise, easy-to-implement recipes for day-to-day management, such as user rights, backup strategies, and hardware maintenance.

The animal on the cover of XenServer Administration Handbook is a plain xenops (Xenops minutus). It is part of the Furnariidae family and can be found throughout the rainforests of Central and South America, as well as Mexico. They are also known as "ovenbirds."
Both males and females have a similar look, but immature xenopses have dark brown throats. Adults are fairly small, weighing an average of 12 grams and measuring about 12 centimeters in length. Plummage on the heads is a light brown, with an even lighter stripe that starts from the base of the bill, extends above the eye, and ends toward the back of the head. Their "cheeks" also include a lighter-colored strip of plummage. The rest of the body is also of a brown color, but turns slightly reddish toward the tail. Wings are of a darker shade of brown than the upper parts.
The plain xenops' diet relies heavily on insects (namely ants) and their larvae caught within decaying tree and shrub branches. The bird is sometimes hard to spot as it moves in all directions on tree trunks, in search of its next meal.
When breeding, both male and female plain xenops create a nest between 1.5 and 9 meters off the ground, within a tree trunk or branch in decay. Both sexes also take turns in incubating the eggs. Each female averages two eggs per breeding.

Comments about oreilly XenServer Administration Handbook:
Considered one of the leading hypervisors, XenServer has undergone major renovation and rejuvenation since being open-sourced back in the spring of 2013. Since then, the latest stable release of XenServer 6.5 SP1 supports many new features that have been added or revived while better performance and scalability make for a platform capable of handling the demands of desktop and server virtualization, alike. This compilation covers the basics of installation and guest operating system deployment, as well as many important aspects of general system administration presented in practical terms. Lots of tips, tricks and caveats are presented that can be put good use. The authors have a treasure trove of experience to draw on and share details not only hard to find in general. The emphasis of this book is very much on the "practical recipes" aspect. As a bonus, some information on the anticipated differences and enhancements with the next XenServer release, code-named Dundee, are given.
