我的环境：

Virtualbox 4.3.10 r93012

操作系统：win7

问题：Virtualbox在使用拷贝的虚拟盘时会提示uuid冲突：

Because a hard disk with uuid ‘’ already exists.

按照网上的说法，运行VBoxManage修改uuid报错：

D:\Program Files\Oracle\VirtualBox>VBoxManage internalcommands sethduuid D:\vm\

rac1\model.vdi

VBoxManage.exe: error: Failed to create the VirtualBox object!

VBoxManage.exe: error: Code E_INVALIDARG (0x80070057) - One or more arguments ar

e invalid (extended info not available)

VBoxManage.exe: error: Most likely, the VirtualBox COM server is not running or

failed to start.

解决办法：

将vboxmanage修改为以兼容模式运行这个程序即可，如下图：

重新运行命令即可：

D:\Program Files\Oracle\VirtualBox>VBoxManage internalcommands sethduuid D:\vm\

rac1\model.vdi

UUID changed to: f52953fb-b3d1-400c-b345-dc4de6acaf75
