How to configure IPv6 in OpenVZ?

Question

OpenVZ

I'm trying to make friends with IPv6 in OpenVZ.
On the node, the address is 2a02:29e0:1:194::2
sysctl.conf

net.ipv4.ip_forward=1
net.ipv4.conf.default.proxy_arp=0
kernel.sysrq=1
net.ipv4.conf.default.send_redirects=1
net.ipv4.conf.all.send_redirects=0

net.ipv6.conf.default.forwarding = 1
net.ipv6.conf.all.forwarding = 1
net.ipv6.conf.all.proxy_ndp = 1

At the guest, IPv6 is added to venet0, IPv4 to venet0:0
Pings go to node 2a02:29e0:1:194::2 , and get stuck there.
The guests do not see each other either.
Maybe something is missing?

You need to execute on the virtualization host:
eth0 is the public interface.
Why the openvz snap-in doesn't do this is unclear.
