lazyvm

Start a vm on incoming remote session connection and put it to sleep on idle.

Documentation

Overview

Package lazyvm provides a proxy for RDP connections, which is capable of starting / stopping on idle Windows instances through VirtualBox manager.

Actually it treats underlying connection as a blackbox, so it can be used with different protocols / OSes. It was just developed for use with rdesktop and Windows.
