Vagrant is a tool for building and distributing development environments.

VagrantPlugins::ProviderVirtualBox::Cap.forwarded_ports

Reads the forwarded ports that currently exist on the machine
itself. This raises an exception if the machine isn't running.

This also may not match up with configured forwarded ports, because
Vagrant auto port collision fixing may have taken place.
