Instance Method Details

#delete ⇒ Object

Public: Deletes a VM. The VM must not be running in order to delete it. As there are a number issues with the Fusion command line tool for deleting VMs, this is a best effort. The VM must not be running when this method is called. This essentially deletes the VM directory and attempts to remove the relevant entries from the Fusion plist file. It’s highly recommended to delete VMs without the Fusion GUI running. If the Fusion GUI is running this method should succeed, but it’s been observed that Fusion will recreate the plist data which is deleted. This leads to ‘missing’ VMs in the Fusion GUI.

Examples

@deleter.delete

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.
