-At test "tear down", ``avocado_qemu.Test`` handles the QEMUMachine
+The base test class has also support for tests with more than one
+QEMUMachine. The way to get machines is through the ``self.get_vm()``
+method which will return a QEMUMachine instance. The ``self.get_vm()``
+method accepts arguments that will be passed to the QEMUMachine creation
+and also an optional `name` attribute so you can identify a specific
+machine and get it more than once through the tests methods. A simple
+and hypothetical example follows:
