Oracle VM VirtualBox 打开复制虚机报错

Oracle VM VirtualBox 

which has the same UUID as an existing virtual machine.

1. run VBoxManage internalcommands sethduuid <VDI/VMDK file> twice (the first time is just to conveniently generate an UUID, you could use any other UUID generation method instead)
2. open the .vbox file in a text editor
3. replace the UUID found in <Machine uuid="{...}" with the UUID you got when you ran sethduuid the first time
4. replace the UUID found in <HardDisk uuid="{...}" and in <Image uuid="{}" (towards the end) with the UUID you got when you ran sethduuid the second time

You can add the virtual machine after that. Not a very clean solution, but does not seem to cause any problem.

用命令行进入VirtualBox的安装目录，使用下面的命令

C:\Program Files\Sun\VirtualBox>VBoxManage  internalcommands setvdiuuid D:\path\ubuntu.vdi

 注意，在virtualbox4.0.4以上该命令改为

C:\Program Files\Sun\VirtualBox>VBoxManageinternalcommands sethduuid D:\path\ubuntu.vdi

然后重新导入即可。
