This means you're using the wrong Machine object, or completely lack the
session handling... it works fundamentally the same way as if the VM
isn't running: create a session, get a shared lock (an exclusive one
isn't possible while the VM is running), and use the Machine reference
associated with this session.
That one is writable.
