vboxmanage clonehd \computername\c$\harddisks\harddrive.vdi c:\harddisks\newname.vdi
use Virtualbox Media Manager and add it as a hard disk
or
???VBoxManage createhd -filename "centos5.vdi" -size 10000 -register
In order to move vdi and image file to another location, change the following (highlighted in bold) in VirtualBox.xml to reflect it (no changes in uuid is required)
1) Copied the disk.vdi file 2) Copied the Corresponding directory from the Machines directory 3) In the Virtual Box control application registered the copied disk.vdi 4) Manually added the MachineEntry tag in the MachineRegistry in the VirtualBox.xml. (Made sure I got the right guid for the copied machine.
5) In the Server.xml changed the version attribute on the VirtualBox tag from 1.6-linux to 1.6-windows.
6) Went back to the Virtual Box console and change the interface adapter from eth0 to the actual network adapter on the windows box.
