QEMU/KVM查看虚拟机系统注册表的方法【百科全说】

libguestfs-tools套件提供了一个基于QEMU的磁盘映像去查找这个磁盘映像中安装的Windows操作系统的具体注册表信息，甚至是进行改动（当然不安全，目前可能不成熟，可能损坏映像文件）。

这个套件目前我只在centos和redhat的虚拟化环境中找到了，具体安装方法很简单：

复制代码

代码如下:

yum install libguestfs libguestfs-tools libguestfs-winsupport

安装完成之后，使用virt-win-reg既可以对已经安装操作系统的虚拟机映像文件进行注册表的读取操作,不过要注意的是目前只推荐在虚拟机停止状态下获取注册表的信息，如果在启动模式下获取注册表或者修改注册表信息都可能导致虚拟机映像文件损坏。

具体使用方法如下：

复制代码

代码如下:

virt-win-reg win9-clone 'HKEY_LOCAL_MACHINE/Software/Microsoft/Windows/CurrentVersion/Uninstall'

其中win9-clone是虚拟机的名字，可以通过libvirt的virsh list –all命令查询得出，不过一定确保虚拟机已经是停止的状态，否则可能造成磁盘损坏。

上面的命令最终执行的结果如下：

代码如下:

该命令的其他用法可以使用man virt-win-reg获取相关帮助信息，用法还是很多的哦
