磁碟檔案格式 IMG,VMDK,VDI,VHD轉換

參考http://blog.tenyi.com/2009/12/convert-from-vmdkvhd-to-vdi-format.html

不再需要vditool或qemu，直接利用VirtualBox附的VBoxManage就可以轉換虛擬硬碟的格式。

把vmdk或vhd轉成vdi的指令:

VBoxManage clonehd source.vmdk target.vdi --format VDI

--format

是指target (目標檔案)格式，source的格式似乎會自動判斷

Your are no longer needed to use vditool, the tool "VBoxManage" comes with recent revision VirtualBox.

Just type the command:

VBoxManage clonehd source.vmdk target.vdi --format VDI

- format

refers to the target format, source format seems to be automatically determined.
