   Hi Josh,

 Thanks for your report - what happened is that you hit some form of 
subtlety in VirtualBox interfaces.
Unfortunately, you cannot use '' as 'null' UUID, as described in 
createMachine() documentation.
Instead the right code should be

vm = vbox.createMachine('WinXP2', 'WindowsXP', '', '00000000-0000-0000-0000-000000000000')

I will update VBox shell with proper createMachine() example.
