Convert VDI file to VHD virtual hard disk format file

I had a dilemma , where I needed to run my VirtualBox virtual Windows XP OS, in another PC running Microsoft Virtual PC 2007. As you would know, Virtual PC 2007 would require the virtual OS harddisk file to be in VHD format. But my virtual Windows XP OS is in a VDI format file. So how ?

A check on the Internet shows VirtualBox comes with a command-line tool called VBoxManage, which includes functions to convert VDI files to VHD files. Cool !

Below is the command sequence which allowed me to convert the VDI file to VHD file. Phew !

Problem solved !

Command sequence as below :

a) Location of VBoxManage.exe -> d:\Program Files\Sun\VirtualBox
b) Location of VDI virtual OS file -> d:\virtual_os\Windows_2003_R2_30GB_11june10.vdi
c) Target output filename to D drive -> d:\sharepoint.vhd
========================================

d:\Program Files\Sun\VirtualBox>vboxmanage.exe clonehd d:\virtual_os\Windows_200
3_R2_30GB_11june10.vdi d:\sharepoint.vhd --format vhd
