The default container network adapter is venet which has the same MAC address as the host and only allows you to do layer 3 stuff.  If you want to do layer 2 stuff you have to use use a veth device which you can assign a MAC address to.

See the wiki page on the differences between venet and veth:

http://wiki.openvz.org/Differences_between_venet_and_veth

I don't have a need for the layer 2 stuff so I stick with the default.

Hopefully there is enough documentation on setting up veth.  I know the man page for vzctl covers it as well as a few wiki pages... but sometimes I get the feeling from some users who appear in IRC... that it can be a bit confusing.

TYL,
