[lxc-users] Is there a guide to LXC & ipv6 configuration

[Xavier Gendre]

Hi,

you can simply pass the IPv6 address you want to give to your container 
via the configuration file through 'lxc.network.ipv6'. For instance, if 
you gave the local address fe80::1 to the interface lxcbr0, you can do 
it with the following configuration file:

# Sample config file
lxc.network.type = veth
lxc.network.flags = up
lxc.network.link = lxcbr0
lxc.network.ipv6 = [the ipv6 address here]/128
lxc.network.ipv6.gateway = fe80::1

Note that you can give multiple IPv6 addresses by writing multiple lines 
which start with 'lxc.network.ipv6'. This is useful for giving a local 
and a global address to the interface in the container, for instance.

Then, create your container with the following command,
lxc-create -n container_name -f /path/to/config_file -t xxx [...]

Your container will receive the given IPv6 address. The sequel is just 
routing IPv6 traffic (ip -6 route add [...]) and allowing it in your 
firewall (ip6tables [...]).

Do not hesitate to ask if you need more details.
