KVM(Kernel-based Virtual Machine)

Kernel Based Virtual Machine

KVM (Kernel-based Virtual Machine的简写) is a full virtualization solution for Linux on x86 hardware containing virtualization extensions (Intel VT or AMD-V). It consists of a loadable kernel module, kvm.ko, that provides the core virtualization infrastructure and a processor specific module, kvm-intel.ko or kvm-amd.ko. KVM also requires a modified QEMU although work is underway to get the required changes upstream.

KVM (Kernel-based Virtual Machine的简写)是一个基于X86硬件的完整的Linux虚拟化的解决方案，它包括虚拟化扩展（Intel VT或者是AMD-V）。它由一个可下载的核心模块——kvm.ko和一个特定处理器模块——kvm-intel.ko或kvm-AMD.ko组成，其中kvm.ko提供了核心的虚拟化架构。

Using KVM, one can run multiple virtual machines running unmodified Linux or Windows images. Each virtual machine has private virtualized hardware: a network card, disk, graphics adapter, etc.

通过使用kvm，我们可以运行多个虚拟机，这些虚拟机上运行着未修改的Linux或windows影响。每个虚拟机都有着私有的虚拟硬件：一个网卡、磁盘、图像适配器等等。

The kernel component of KVM is included in mainline Linux, as of 2.6.20.

KVM的核心组件包含在Linux主线程中，作为一个26.20。

KVM is open source software.

KVM是一个开源的软件。

所谓KVM，就是Keyboard、Video、Mouse的缩写，正式的名称为多计算机切换器。简单的说，就是一组键盘、显示器和鼠标，控制2台、4 台、8台、16台甚至到4096台以上的计算机主机。
