Network for LXC container

Host device as bridge

• persisted in host's /etc/network/interfaces the container's veth virtual ethernet interface can share the network link on the physical interface of the host (eth0). So the container resides on the same ethernet segment and talks to the same dhcp server as the host does.

Additonal bridge device

• setup manually with brctl
