IPv6 configuration for KVM guests

It is simple and straight forward to enable IPv6 on KVM guests

Configure the host machine with IPv6 Address on the bridge interface

cat ifcfg-br0

IPV6INIT=yes
IPV6ADDR=xxxx.xx::10
IPV6_DEFAULTGW=xxxx.xx::1
IPV6_AUTOCONF=no

Configure the interface on virutal machines with ipv6 address

cat ifcfg-eth0

IPV6INIT=yes
IPV6ADDR=xxxx.xx::11
IPV6_DEFAULTGW=xxxx.xx::1
IPV6_AUTOCONF=no

Add the the necessary firewall rules to ip6tables on the host machine

-A FORWARD -m physdev –physdev-is-bridged -j ACCEPT.
