OpenVZ and IPv6 configurationPosted by Marius Voila on June 23, 2010 in London, U.K . — 0 comments This post contains 145 words
I have not found any recommentation to configure IPv6 for Debian/Lenny/Ubuntu OpenVZ hosts. The OpenVZ project always lacks a bit of documentation when it comes to v6, so here is how you get it working with venet devices.
Add the following to your /etc/sysctl.conf to enable IPv6 package forwarding and proxy neighbor discovery (RFC 4389).
# IPv6 Packet Forwarding and Proxy NDP net.ipv6.conf.default.forwarding = 1 net.ipv6.conf.all.forwarding = 1 net.ipv6.conf.default.proxy_ndp = 1 net.ipv6.conf.all.proxy_ndp = 1
Be sure to set a manual route to your default gateway. Once you enable IPv6 package forwarding on your interfaces, routes for auto discovered default gateways are removed from the routing table.
Enable IPv6 in your /etc/vz/vz.conf:
Now just add a new address to one of your containers and enjoy. ;)
