The following worked for me:
- run VBoxManage internalcommands sethduuid “VDI/VMDK file” twice (the first time is just to conveniently generate an UUID, you could use any other UUID generation method instead)
- open the .vbox file in a text editor
- replace the UUID found in Machine uuid=”{…}” with the UUID you got when you ran sethduuid the first time
- replace the UUID found in HardDisk uuid=”{…}” and in Image uuid=”{}” (towards the end) with the UUID you got when you ran sethduuid the second time
