\section*{About Linux-VServer}

Linux-VServer provides virtualization for GNU/Linux systems. Virtualization
is a framework or methodology of dividing the resources of a computer
into multiple execution environments. This is accomplished by kernel
level isolation. It allows to run multiple virtual units at once.
Those units are sufficiently isolated to guarantee the required security,
but utilize available resources efficiently, as they run on the same
kernel.

The basic concept of the Linux-VServer solution is to separate the
user-space environment into distinct units (sometimes called Virtual
Private Servers) in such a way that each VPS looks and feels like
a real server to the processes contained within. 

Although different Linux distributions use (sometimes heavily) patched
kernels to provide special support for unusual hardware or extra functionality,
most Linux distributions are not tied to a special kernel. 

Linux-VServer uses this fact to allow several distributions, to be
run simultaneously on a single, shared kernel, without direct access
to the hardware, and share the resources in a very efficient way.
