Package: linux-image-2.6.26-2-openvz-amd64
Version: 2.6.26-15lenny2
Tags: lenny,ipv6
IPv6 does not work in OpenVZ containers when hardware node is using the
linux-image-2.6.26-2-openvz-amd64 kernel: containers are unable to reach
any IPv6 host other than himself and the hardware node.
This does not affect the IPv6 connectivity of the hardware node itself,
only hosted containers.
Booting the hardware node with the Debian-Systs 2.6.18 "Fortezza" kernel
(linux-image-2.6.18-14-fza-amd64, version 028stab056.1dso1), without
changing anything else, restores proper IPv6 functionlality in
containers, so the issue seems kernel or kernel-version related.
This bug has been filed on the OpenVZ bug tracker:
http://bugzilla.openvz.org/show_bug.cgi?id=1287
Test setup is:
- Debian Lenny hardware node
- Debian Etch, Lenny and CentOS containers
- containers use venet devices
- IPv6 forwarding is globally enabled (/sbin/sysctl -q -w
net.ipv6.conf.all.forwarding=1), and hardware node public ethernet
device is statically IPv6-configured

thanks for having reported upstream, to enable ipv6 one has to:
echo 1 > /proc/sys/net/ipv6/conf/all/proxy_ndp
and for each VE :
echo ip -6 neigh add proxy $IPV6 dev eth0;
thus closing.
