How to check the uuid of a virtualbox vdi?

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

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

I k开发者_开发问答now I read it some place in the docs, but now for some reason I can't find it...

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

Run VBoxManage and pass it showhdinfo and your VDI:

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

You can open C:\Users\username\.VirtualBox\VirtualBox.xml for .vbox files:

<VirtualBox>
  <Global>
    <MachineRegistry>
      <MachineEntry uuid="{11111111-1111-1111-1111-111111111111}" src="C:/mybox.vbox"/>
    </MachineRegistry>
  </Global>
</VirtualBox>
