This approach is also described in [[virtual Ethernet device]].
In the container configuration file, /etc/vz/conf/$CTID.conf, add the line <pre>CONFIG_CUSTOMIZED="yes"</pre> Now create Create the file /etc/vz/vznet.conf or /etc/vz/vznetcfg. Note that this will only work with a recent version of OpenVZ (vzctl-3.0.14) as the change was introduced in December, 2006. The file name seems to have changed between the two listed here so some trial and error may be required.
