OpenVZ consists of a kernel, user-level tools, and container templates.
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''').
OpenVZ per-container disk quota is supported only for ext2/ext3 filesystems; therefore it makes sense to use one of these filesystems (ext3 is recommended) if you need per-container disk quota.
=== Repository setup (Etch only) ===
'''If you are using Debian Lenny, this step in no longer required. Openvz kernel packages and tools are available on main repository.'''
==== 1. Using openvz.org repositories ====
# wget -q http://download.openvz.org/debian-systs/dso_archiv_signing_key.asc -O- | apt-key add - && apt-get update
</pre>
==== 2. Using Debian repositories (upgrade to lenny) ====
Then '''apt-get update && apt-get dist-upgrade''' to upgrade to lenny.
== Kernel installation ==
{{Note|The best kernel to use is [[Download/kernel/rhel6|RHEL6-based]]. Please see [[Install_kernel_from_RPM_on_Debian_6.0]]}}
=== Etch ===
# apt-get install <kernel>
</pre>
===== Configuring the bootloader =====
{{Note|per default on debian/ubuntu, a 2.6.22 kernel will boot before a 2.6.18, please check manually the grub boot order. See man update-grub for more details}}
===== Installing the user-level tools =====
# [sudo] apt-get install vzctl vzquota
</pre>
==== 2 Using Debian lenny repositories ====
</pre>
and will arrange grub bootloader properly.
=== Rebooting into OpenVZ kernel ===
Now reboot the machine and choose the OpenVZ Linux Kernel on the boot loader menu. If the OpenVZ kernel has been booted successfully, proceed to installing the user-level tools for OpenVZ.
=== Confirm proper installation ===

== Configuring ==
# [sudo] ln -s /var/lib/vz /vz
=== OS templates ===
On Debian squeeze, vzdump seems packaged in standard aptline. For lenny, See [[Backup_of_a_running_container_with_vzdump]]
