KVM同hyper-V、Xen都是指在CPU硬件支持基础之上的虚拟化技术。 

KVM是Linux的一个模块。用modprobe加载KVM模块。加载了模块后，才能进一步通过其他工具创建虚拟机。
只有KVM模块是不够的，因为用户无法直接控制内核模块去作事情：还必须有一个用户空间的工具才行。
这个用户空间的工具，即已经成型的开源虚拟化软件 QEMU。

The KVM project is maintaining a fork of QEMU called qemu-kvm. Currently (close to the 1.1 release) it still provides the best performance and certain additional features for using KVM with QEMU on x86. Any other architecture is already fully supported by QEMU itself. The goal is to merge all remaining feature differences into QEMU upstream, provide a migration path from qemu-kvm and suspend the development of this fork.
