Configuring IPV6 in a VE

Assuming you are using veth devices to enable networking on the host for its VEs, you simply setup the /etc/sysconfig/network-scripts/ifcfg-ethN files exactly the same way as for a non-VE system. If you are using IPv6 auto-configuration you wont have to add anything special to the VE icfg-ethN files. Otherwise, standard Linux HOWTOs for configuring IPv6 apply to the VE and are not duplicated here.
