Hi,
after upgrade to vzctl version 3.0.18-1dso1 I got new set of
/etc/vz/dists/scripts/. There were changes in IPv6 code for Debian.
Thanks to those changes now IPv6 works between HW node and VE:
> staj-dev:~# ping6 2001:718:1:e::23:3005
> PING 2001:718:1:e::23:3005(2001:718:1:e::23:3005) 56 data bytes
> 64 bytes from 2001:718:1:e::23:3005: icmp_seq=1 ttl=64 time=0.068 ms
Problem is that I still can not reach VE from outside (staff is box with
IPv6 support).
> semik@staff:~$ ping6 2001:718:1:e::23:3005
> PING 2001:718:1:e::23:3005(2001:718:1:e::23:3005) 56 data bytes
ping does not show anything, it just hangs. In tcpdump on HW node I see:

I was suspecting route problems but routes does look ok. VE:
> root@ipv6-pokus:/# route -6
> Kernel IPv6 routing table
> Destination Next Hop Flags Metric Ref Use Iface
> ::1/128 :: U 0 1 1 lo
> ::1/128 :: U 0 0 1 lo

HW node:
