[$] Using the KVM API

Many developers, users, and entire industries rely on virtualization, asprovided by software like Xen,QEMU/KVM, orkvmtool.While QEMU can run a software-based virtual machine, and Xen can runcooperating paravirtualized OSes without hardware support, most current usesand deployments of virtualization rely on hardware-accelerated virtualization,as provided on many modern hardware platforms. Linux supports hardwarevirtualization via the Kernel Virtual Machine (KVM) API. In this article,we'll take a closer look at the KVM API, using it to directly set up a virtualmachine without using any existing virtual machine implementation.
