-         LibVirt : simple API for virtualization
-
-  Libvirt is a C toolkit to interact with the virtualization capabilities
-of recent versions of Linux (and other OSes). It is free software
-available under the GNU Lesser General Public License. Virtualization of
-the Linux Operating System means the ability to run multiple instances of
-Operating Systems concurrently on a single hardware system where the basic
-resources are driven by a Linux instance. The library aim at providing
-long term stable C API initially for the Xen paravirtualization but
-should be able to integrate other virtualization mechanisms if needed.
