How to check the uuid of a virtualbox vdi?

Question

How can I check the uuid of a vdi or vmdk?

There should be some command line on VBoxManage to show it.

I know I read it some place in the docs, but now for some reason I can't find it...

Answer 1

Run VBoxManage and pass it showhdinfo and your VDI:

VBoxManage.exe showhdinfo "c:\MyMachine.vdi"

Answer 2

VBoxManage list vms will list the virtual machines and their uuids without having to know the path to the particular vdi.
