OpenVZ consists of a kernel, user-level tools, and container templates.
This guide tells how to install the kernel and the tools on [http://www.debian.org Debian] Etch or Lenny/Squeeze.  For Squeeze, use the Lenny directions. For Wheezy (7.0), use the vzctl package included in wheezy, together with the Wheezy OpenVZ kernels from [http://download.openvz.org/debian/ http://download.openvz.org/debian/]. Alternatively reduced functionality may be possible using the stock Debian Wheezy kernel (based on kernel.org version 3.2) and [[Vzctl_for_upstream_kernel]]. You may also wish to check the information on [http://wiki.debian.org/OpenVz the Debian wiki].
For Etch users, this document explains how to partially upgrade to Debian Lenny and install from lenny repositories ('''use this options at your risk''').
