// This is an illustration of how one could use virtualization techniques to
// allow running applications on virtual machines talking over simulated
// networks.
//
// The actual steps required to configure the virtual machines can be rather
// involved, so we don't go into that here. Please have a look at one of
// our HOWTOs on the nsnam wiki for more details about how to get the
// system confgured. For an example, have a look at "HOWTO Use Linux
// Containers to set up virtual networks" which uses this code as an
// example.
//
// The configuration you are after is explained in great detail in the
// HOWTO, but looks like the following:
//
// +----------+ +----------+
// | virtual | | virtual |
// | Linux | | Linux |
// | Host | | Host |
