Instance Method Details

#stop(options = {}) ⇒ Object

Public: Stops a VM. The VM must be running in order to stop it.

options - Hash of options:

:hard - Boolean which specifies to power off the VM (instead
        of attempting to initiate a graceful shutdown). This
        is the equivalent of passing 'hard' to the vmrun
        stop command.
        (default: false)

Examples

@stopper.stop

@stopper.stop :hard => true

Returns a Response with the result. If successful, the Response’s data attribute will be nil. If there is an error, an unsuccessful Response will be returned.
