将已有vdi文件直接复制进行添加时出现以下错误：
打开 虚拟硬盘 D:\vdisk\orale10g.vdi失败.
Cannot register the hard disk ‘D:\vdisk\orale10g.vdi‘{4b186303-3784-4e7c-836f-3581c090becc} because a hard disk ‘D:\vdisk\10g\orale10g.vdi‘with UUID {4b186303-3784-4e7c-836f-3581c090becc} already exists.
提示信息已经很明了了，需要重置uuid，解决方法如下：
D:\ProgramFiles\Oracle\VirtualBox>VBoxManage -version 4.2.18r88780 D:\ProgramFiles\Oracle\VirtualBox>VBoxManage internalcommands sethduuid d:\vd isk\storage\storage01.vdi UUID changed to:863fc09a-0eb4-488e-81b6-be790dc871f8 D:\ProgramFiles\Oracle\VirtualBox>VBoxManage internalcommands sethduuid d:\vd isk\tracker\tracker.vdi UUID changed to:f3d66095-d16a-456a-9f51-32e94bb123df
VBOX4.0以下命令参数稍有变化：
D:\Program Files\Oracle\VirtualBox>VBoxManage internalcommands setvdiuuid d:\vd isk\tracker\tracker.vdi
