kvm虚拟机启动命令(kvm虚拟机如何安装)

libguestfs-tools套件提供了一个基于QEMU的磁盘映像，可以在这个磁盘映像中查找已安装的Windows作的具体注册表信息，甚至进行更改（当然它不安全，目前可能还不成熟，而且它可能会损坏图像文件）。目前我只在centos和redhat虚拟化环境中找到了这个包。具体安装很简单：代码。代码如下：yuminstalllibguestfslibguestfs-toolslibguestfs-winsupport。安装完成后，您可以使用virt-win-reg来安装作。虚拟机镜像文件用于读取注册表。但需要注意的是，目前建议仅在虚拟机停止时获取日志信息。如果在启动模式下获取或更改注册表信息，可能会导致虚拟机镜像文件损坏。具体使用如下：代码代码如下：virt-win-regwin9-clone'HKEY_LOCAL_MACHINE/Software/Microsoft/Windows/CurrentVersion/Uninstall'其中win9-clone是虚拟机的名称，即可以通过libvirtout的virshlist–all命令查询，但要确保虚拟机已经停止，否则可能会导致磁盘损坏。运行上述命令最终结果如下：代码代码如下：[HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/Windows/CurrentVersion/Uninstall]/pp[HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/Windows/CurrentVersion/Uninstall/AddressBook]@=hex(1):00,00/pp[HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/Windows/CurrentVersion/Uninstall/Branding]"QuietUninstallString"=hex(1):52,00,75,00,6e,00,64,00,6c,00,6c,00,33,00,32,00,20,00,49,00,65,00,64,00,6b,00,43,00,53,00,33,00,32,00,2e,00,64,00,6c,00,6c,00,2c,00,42,00,72,00,61,00,6e,00,64,00,43,00,6c,00,65,00,61,00,6e,00,49,00,6e,00,73,00,74,00,61,00,6c,00,6c,00,53,00,74,00,75,00,62,00,73,00,00,00"需要IESysFile"=十六进制(1):31,00,30,00,30,00,2e,00,30,00,00,00/页[HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/Windows/CurrentVersion/Uninstall/ConnectionManager]“SystemComponent”=dword:00000001/pp[HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/Windows/CurrentVersion/Uninstall/DXM_Runtime]/pp[HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/Windows/CurrentVersion/Uninstall/DirectAnimation]@=hex(1):00,00/pp[HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/Windows/CurrentVersion/Uninstall/DirectDrawEx]@=hex(1):00,00/pp[HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/Windows/CurrentVersion/Uninstall/Fontcore]@=hex(1):00,00/pp[HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/Windows/CurrentVersion/Uninstall/ICW]@=hex(1):00,00/pp[HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/Windows/CurrentVersion/Uninstall/IE40]@=hex(1):00,00/pp[HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/Windows/CurrentVersion/Uninstall/IE4Data]@=hex(1):00,00/pp[HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/Windows/CurrentVersion/Uninstall/IE5BAKEX]@=hex(1):00,00/pp[HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/Windows/CurrentVersion/Uninstall/IEData]@=hex(1):00,00/pp[HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/Windows/CurrentVersion/Uninstall/MPlayer2]/pp[HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/Windows/CurrentVersion/Uninstall/MobileOptionPack]@=hex(1):00,00/pp[HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/Windows/CurrentVersion/Uninstall/NetMeeting]"RequiresIESysFile"=hex(1):34,00,2e,00,37,00,31,00,00,00/pp[HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/Windows/CurrentVersion/Uninstall/OutlookExpress]@=hex(1):00,00/pp[HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/Windows/CurrentVersion/Uninstall/PCHealth]"QuietUninstallString"=hex(1):72,00,75,00,6e,00,64,00,6c,00,6c,00,33,00,32,00,2e,00,65,00,78,00,65,00,20,00,73,00,65,00,74,00,75,00,70,00,61,00,70,00,69,00,2e,00,64,00,6c,00,6c,00,2c,00,49,00,6e,00,73,00,74,00,61,00,6c,00,6c,00,48,00,69,00,6e,00,66,00,53,00,65,00,63,00,74,00,69,00,6f,00,6e,00,20,00,44,00,65,00,66,00,61,00,75,00,6c,00,74,00,55,00,6e,00,69,00,6e,00,73,00,74,00,61,00,6c,00,6c,00,20,00,31,00,33,00,32,00,20,00,43,00,3a,00,5c,00,57,00,49,00,4e,00,44,00,4f,00,57,00,53,00,5c,00,49,00,4e,00,46,00,5c,00,50,00,43,00,48,00,65,00,61,00,6c,00,74,00,68,00,2e,00,69,00,6e,00,66,00,00,00"卸载字符串"=hex(1):72,00,75,00,6e,00,64,00,6c,00,6c,00,33,00,32,00,2e,00,65,00,78,00,65,00,20,00,73,00,65,00,74,00,75,00,70,00,61,00,70,00,69,00,2e,00,64,00,6c,00,6c,00,2c,00,49,00,6e,00,73,00,74,00,61,00,6c,00,6c,00,48,00,69,00,6e,00,66,00,53,00,65,00,63,00,74,00,69,00,6f,00,6e,00,20,00,44,00,65,00,66,00,61,00,75,00,6c,00,74,00,55,00,6e,00,69.00,6e,00.73,00.74,00,61,00.6c,00.6c,00,20,00,31,00,33,00,32,00,20,00,43,00,3a,00,5c,00,57,00,49,00,4e,00,44,00,4f,00,57,00,53,00,5c,00,49,00,4e,00,46.00,5c,00.50,00,43,00,48,00,65,00,61,00,6c,00

首先你需要了解qemu和libvirt。
QEMU（QuickEmulator）是一种广泛使用的开源计算机模拟器和虚拟机。它是一个、开源、纯软件实现的VMM，可以执行硬件虚拟化。
libvirt是目前使用最广泛的用于管理KVM虚拟机的工具和API。它本质上是一些库函数（C语言）。它是指面向驱动的架构设计，支持所有虚拟化。每种技术都提供了相应的驱动程序和统一的接口来管理虚拟机到物理机。Libvirt具有非常强的可扩展性，可以被本地或远程virsh调用。
Qemu-kvm命令属于QEMU，virt-install命令属于libvirt。libvirt调用qemu-kvm来管理虚拟机。如果hypervisor是KVM，只是命令参数不同，没有区别。

无法访问KVM内核模块：没有类似的文件或目录
KVM初始化失败：没有类似的文件或目录
错误：启动失败：命令'/usr/bin/kvm-id101-chardev
如果个软件崩溃，请检查注册表或重新安装第二个虚拟机：文件消失了，GG也消失了。
