Yup. See below for most of the config you can use as a reference in making it
work.
And to allocate an interface to a container, pairing it up with a host node
bridge interface, I run:
vzctl set <id> --netif_add eth0.<vlan>,,veth<id>.<vlan>,,brvl<vlan> --save
where
<id> := container id
<vlan> := vlan id
brvl<vlan> := logical bridge name
That will allocate a MAC address for you automatically.
[r...@hc ~]# brctl show
bridge name bridge id STP enabled interfaces
brvl10 8000.001851aa1922 no veth101.10
veth24.10
veth26.10
eth0.10
Containers 101, 24 and 26 are all bridged to eth0.10. Here's the
output if ifconfig in the containers & host node.
