I can confirm that IPv6 works (dual-stack IP4/6) on Ubuntu. I set it up with Folsom and 12.04 LTS. You might have troubles with duplicate address detection on Ubuntu guests, but it can be disabled (not sure if it's a bug on Debian/Ubuntu or what). I used nova networking (both Flat DHCP and VLAN) and nova starts radvd as necessary. Guests and host communicate with v6, firewall is not fully supported for v6 so it's for testing only. I didn't get v6 to the Internet though, as I have multiple interfaces on host and the one OpenStack is on is not connected to Internet - still looking into how to best connect this all :)

I tried the devstack (master branch) juno version in ubuntu14.04 . I am able to setup ipv6 in Flat DHCP. where it takes IP from my external dhcp server. But When i tried for VLAN with manual(static) configuration ipv6 works. But dnsmasq is not starting for ipv6 hence dhcp is not working. Any idea?

Hi there, I have been for the past month trying this, and was not able to, finally last week I received an email from redhat support team saying that redhat/centos systems don't support openstack ipv6 full implementation(due to a dnsmask issue). Killing me, and all my project work. Openstack supposely supports full ipv6 implementation, I am thus investigating which OS should I pick. My next option is ubuntu server. Will post more feedback while I advance on this.
