Well, I was lazy when I tested the IPv6 patch so I hacked up
http://daniel.hozac.com/vserver/chbind6.c
Compile it with
gcc -lvserver -I<path to kernel tree>/include -o chbind6 chbind6.c
If you're using util-vserver 0.30.210, you should be able to start the
guest, run
chbind6 -a -n <xid, 42 from your example> -6 <IPv6 address>
and it should be assigned (check /proc/virtnet/<xid>/info to make sure).
