<h1>OpenVZ container driver</h1>
<p>
The OpenVZ driver for libvirt allows use and management of container
based virtualization on a Linux host OS. Prior to using the OpenVZ
driver, the OpenVZ enabled kernel must be installed &amp; booted, and the
OpenVZ userspace tools installed. The libvirt driver has been tested
with OpenVZ 3.0.22, but other 3.0.x versions should also work without
undue trouble.
</p>
<h2>Connections to OpenVZ driver</h2>
<p>
The libvirt OpenVZ driver is a single-instance privileged driver,
with a driver name of 'openvz'. Some example conection URIs for
the libvirt driver are:
</p>
<pre>
openvz:///system (local access)
openvz://example.com/system (remote access, TLS/x509)
openvz+tcp://example.com/system (remote access, SASl/Kerberos)
openvz+ssh://root@example.com/system (remote access, SSH tunnelled)
</pre>
<h2>Notes on bridged networking</h2>
<p>
Bridged networking enables a guest domain (ie container) to have its
network interface connected directly to the host's physical LAN. Before
this can be used there are a couple of configuration pre-requisites for
the host OS.
</p>
<h3>Host network devices</h3>
<p>
One or more of the physical devices must be attached to a bridge. The
process for this varies according to the operating system in use, so
for up to date notes consult the <a href="http://wiki.libvirt.org">Wiki</a>
or your operating system's networking documentation. The basic idea is
that the host OS should end up with a bridge device "br0" containing a
physical device "eth0", or a bonding device "bond0".
</p>
<h3>OpenVZ tools configuration</h3>
<p>
OpenVZ releases later than 3.0.23 ship with a standard network device
setup script that is able to setup bridging, named
<code>/usr/sbin/vznetaddbr</code>. For releases prior to 3.0.23, this
script must be created manually by the host OS adminstrator. The
simplest way is to just download the latest version of this script
from a newer OpenVZ release, or upstream source repository. Then
a generic configuration file <code>/etc/vz/vznetctl.conf</code>
must be created containing
</p>
<pre>
#!/bin/bash
EXTERNAL_SCRIPT="/usr/sbin/vznetaddbr"
</pre>
<p>
The host OS is now ready to allow bridging of guest containers, which
will work whether the container is started with libvirt, or OpenVZ
tools.
</p>
<h2>Example guest domain XML configuration</h2>
<p>
The current libvirt OpenVZ driver has a restriction that the
domain names must match the OpenVZ container VEID, which by
convention start at 100, and are incremented from there. The
choice of OS template to use inside the container is determined
by the <code>filesystem</code> tag, and the template source name
matches the templates known to OpenVZ tools.
