How to change UUID of VirtualBox vdi and VHD

ERROR: Cannot register the hard disk '/*/*.vmdk' with UUID {af38d7f6-a3e0-448a-95a9-4a06ab5e07bc} because a hard disk '/*/*/test_virtual_machine.vmdk' with UUID {af38d7f6-a3e0-448a-95a9-4a06ab5e07bc} already exists in the media registry ('/*/*/.VirtualBox/VirtualBox.xml')

 

Or this Error

Failed to open the hard disk ….” and “Cannot register the hard disk C:\path\to\new\vdi with UUID {xxxx} because a hard disk C:\path\to\old\vdi already exists in the media registry (C:\path to VirtualBox.xml

 

 

To troubleshoot this,

1.1 Open Command Prompt in Administrator mode, and then go in to “C:\Program Files\Oracle\VirtualBox”

Cd C:\Program Files\Oracle\VirtualBox

 

If you run “Dir” you can see all the files in there

 

 

Then run “VBoxManage internalcommands sethduuid /path/to/virtualdisk.vdi”

NOTE: The command has been changed in previous versions on the Virtual box. So in that case command in there would be…

VBoxManage.exe internalcommands setvdiuuid "C:\path\to\new\vdi"

IN my case I’ll run it as “VBoxManage internalcommands sethduuid D:\Share\win2008R2\NewVHD1.vhd”

Because I’m using Virtual box Version 4.1.8

Congratulations again. VPC will work now.

If you want co configure a VPC in Oracle VM VirtualBox please see this Post,

If you are running Windows 8 and  if you get below mentioned error,

 

 

VBoxManage.exe: error: Failed to create the VirtualBox object!
VBoxManage.exe: error: Code CO_E_SERVER_EXEC_FAILURE (0x80080005) - Server execu
tion failed (extended info not available)
VBoxManage.exe: error: Most likely, the VirtualBox COM server is not running or
failed to start.

 

Then what you have to do is Close all the  Oracle VM applications running and try to chaneg the UUID in command line. this should work and make sure to run CMD in Run as administrator mode.
