The IPv6 addresses which are balanced with keepalived are all configured 
with transparent. There I don't have any issues.

I have the issue with the fixed IPv6 Address of the interface, specified 
in /etc/network/interfaces

iface eth0 inet6 static
         address 2001:629:1005:30::11
         netmask 64

This address takes some seconds to become available.

And I have in my global file following peers:

peers ha-cluster-v6
         peer ha1 2001:629:1005:30::11:1024
         peer ha2 2001:629:1005:30::12:1024

and here haproxy tries to bind the port to the IPv6 address but it isn't
