IPV4/6 Venet and IPV4 Bridge

[zhable]

Hello,
I recently was given a /64 of IPV6 for my server and would like to add it for my venet interfaces. As of now and from tons on searching I have IPV4/6 working on openvz, but I can NEVER get KVM bridge to work for IPV4 at the same time(IPV6 is not needed currently for my bridge, but welcomed as a solution). Is this even possible?
Here is my /etc/network/interfaces
# /etc/network/interfaces

### Hetzner Online AG - installimage
# Loopback device:
auto lo
iface lo inet loopback
#
# device: eth0
auto  eth0
iface eth0 inet static
       address   136.243.36.201
       netmask   255.255.255.192
       gateway   136.243.36.193
       broadcast 136.243.36.255
iface eth0 inet6 static
       address   2a01:4f8:212:4ca::2
       netmask   128
       gateway   fe80::1

My /etc/sysctl.conf:

#

# See /etc/sysctl.d/ for additonal system variables
# See sysctl.conf (5) for information.
#


#kernel.domainname = example.com


# Uncomment the following to stop low-level messages on console
#kernel.printk = 3 4 1 3

#net.ipv6.conf.all.accept_source_route = 0

I feel I may have overlooked something or going completely wrong, I have some other previous attempts with vmbr0 as my bridge (got IPV4 to work on bridge & venet, BUT it prevented IPV6 on venet). Any solutions or ideas would be greatly welcome!

According to my experience IPV6 does not work correctly with venet0. In general: if there is venet you should have just 1 IP in the container and nothing else (not a second IP, not a veth device).
