Mostly historical interest; User Mode Linux (UML) was one of the first more performant options for virtualisation of Linux.
This let you play with a network lab based on UML or other technologies without needing to set up a physical network.
This was before hardware virtualisation that we now take for granted. UML was actually the first technology that Linode used for virtualisation, then Xen came along and was a far better option.
