# kvm

[KVM](http://www.linux-kvm.org)（Kernel-based Virtual Machine）是支持虚拟化扩展（Intel VT 或 AMD-V技术）x86硬件的Linux完全虚拟化解决方案。它包括了一个可加载的内核模块`kvm.ko`，提供了核心的虚拟化架构以及一个处理器特定模块（`kvm-intel.ko`或`kvm-amd.ko`）。

使用KVM，用户可以运行多个无需修改的Linux或Windows虚拟机。每个虚拟机有自己私有的虚拟硬件：网卡、磁盘、显卡等等。

从Linux内核2.6.20开始，KVM就作为主线内核，KVM用户空间的组件包括在主线QEMU中。

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://huataihuang.gitbook.io/cloud-atlas-draft/virtual/kvm.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
