Xen allows administrators to run many virtual operating systems on one physical server, including Linux, BSD, OpenSolaris, and Microsoft Windows. In the process, users save money on hardware, maintenance, and electricity. Not only is Xen open source, the Xen hypervisor (the virtual machine monitor) is the best-performing hypervisor available. "The Book of Xen" explains everything a sysadmin needs to know to use this powerful technology, with coverage of installation, networking, virtualized storage, and managing guest and host operating systems. Written for administrators who have worked with *NIX before but who may be new to virtualization, "The Book of Xen" covers both the basics and the trickier aspects of Xen administration, like profiling and benchmarks, migration, XenSource administration, and hardware assisted virtualization (HVM).

If you need an affordable and stable solution to offer high availability for virtual machines, this book is written for you.

Brill’s Companion to Aineias Tacticus is a collection of articles on the significance of the earliest Greek handbook on military tactics. Aineias’ (Aeneas) wrote his Poliorketika in the mid-fourth century BC, offering a unique perspective on contemporary Greek city-states, warfare and intellectual trends. We offer an introduction to Aineias and his work, and then discuss the work’s historical and intellectual context, his qualities as a writer, and aspects of his work as a historical source for the Greek polis of the fourth century BC. Several chapters discuss Aineias’ approach to warfare, specifically light infantry, mercenaries, naval operations, fortifications and technology. Finally, we include a lengthy study of the reception of ancient military treatises, specifically Aineias’ Poliorketika, in the Byzantine period.
