Vagrant is a tool for building and distributing development environments.

Vagrant::Machine#id=

This sets the unique ID associated with this machine. This will
persist this ID so that in the future Vagrant will be able to find
this machine again. The unique ID must be absolutely unique to the
virtual machine, and can be used by providers for finding the
actual machine associated with this instance.

**WARNING:** Only providers should ever use this method.
