As the name suggests, User Mode Linux (UML) is a user-mode
implementation of the Linux kernel.  The result is a light-weight
mechanism for creating virtual Linux machines.  One of the more obvious
and successful applications of UML is hosting virtual Linux servers,
allowing users to take control of their own Linux installation without
the expense of buying and maintaining their own server hardware.

This talk gives details on the workings of UML and also describes the
integration that we have done to implement a UML hosting service.  Along
the way, we will cover a diverse range of topics including:

    * Network bridging
    * Logical Volume Management (LVM) snapshots, for backups
    * Filesystem image manipulation
    * Sparse files
    * Bandwidth monitoring using MRTG

We will also cover a number of tools that we have written, and
(in most cases) released as open source projects, including:

    * blocksync, a utility for performing fast network backups of
      filesystem images
    * consolidate, a logging console manager
    * our server management scripts

... and explain how all this open source goodness fits together to make a
viable hosting service.
