This describes a method of setting up networking for a host and its VEs such that the networking configuration for the VEs can be configured exactly as if the VEs were standalone hosts of their own in the same subnets or VLAN as the host. This method makes use of the Virtual Ethernet device and bridges between the host and its containers. This technique has the advantage of allowing IPv6 network configurations to work on both VEs and hosts as they normally would. In particular, both hosts and VEs can use IPv6 autoconfiguration. The network configuration of a VE can be identical to that of a non-VE system.
In the following example the host has two physical interfaces and we are setting up the network configuration for VE 100. The host IP configuration is moved out of the ethN interface configs and into the vzbrN interface config scripts (ifcfg-vzbr0 and ifcfg-vzbr1). Ie. the host IP configuration will now reside on the vzbrN interfaces instead of the ethN interfaces. The example also assumes IPv4 is configured statically, whereas IPv6 is auto-configured.
