bash
apt-get update
apt-get install build-essential
apt-get install dpkg-dev
apt-get build-dep libvirt
apt-get source --compile libvirtapt-get source --compile libvirt 默认构建的方式是从已安装的版本构建，但是有时候需要从 github 构建, 这个命令不可行, 但是往往使用的起点都是 apt 安装好，然后发现 bug，然后尝试修复，然后回合到社区。
可以考虑把自己修复的 patch 放入这些目录下，然后继续构建。
可以看到 Debian 把 libvirt 当作上游已经有很多自己的 patch：
- backport：有回合的代码
- 也有属于自己操作系统定制的代码
- 也有目前自己修改的代码
