Virtualbox镜像文件克隆问题
今天在克隆一个虚拟机的镜像文件的时候，执行
VBoxManage clonehd centos-1.vdi centos-2.vdi
提示：
ERROR: Cannot register the hard disk '/home/cipher/Data/centos-1.vdi' with UUID {78c1f396-f92a-419b-82d2-843f34b917d2} because a hard disk '/home/cipher/Data/centos-1.vdi' with UUID {78c1f396-f92a-419b-82d2-843f34b917d2} already exists in the media registry ('/home/cipher/.VirtualBox/VirtualBox.xml')
Details: code NS_ERROR_INVALID_ARG (0x80070057), component VirtualBox, interface IVirtualBox, callee nsISupports
Context: "OpenHardDisk(Bstr(szFilenameAbs), AccessMode_ReadWrite, false, Bstr(""), false, Bstr(""), srcDisk.asOutParam())" at line 624 of file VBoxManageDisk.cpp
查找原因分析了半天，原来是这个命令不支持相对路径，修改为
VBoxManage clonehd $(pwd)/centos-1.vdi $(pwd)/centos-2.vdi
一切就正常了。
