current state of IPv6 in 4.6 VR / 4.7
Hi!
I'm currently trying to add dualstack (ipv4 + ipv6) shared networks to
one of our infrastructures. It's running 4.7 w/ latest 4.6 VR on
VLAN-based advanced Networking w/ XenServer 6.5.
The documentation [1] says
"Use the System VM template exclusively designed to support IPv6.
Download the System VM template from [2]"
http://cloudstack.apt-get.eu/systemvm/
Well at that URL are lots of systemvm64templates, but I none of them
mention IPv6. Maybe I missed one?
Anyway, I'ld definitely stay on 4.6 templates...
Does anyone know, if IPv6 is in current templates "only broken", or is
there a different branch for v6 Support?
As far as I can see, the DUID of the provisioned VMs is only visible in
/etc/cloudstack/dhcpentry.json:
"ipv6_duid": "00:03:00:01:06:2d:4a:00:08:47",
I didn't find any code using that DUID in /opt, the running dnsmasq also
doesn't know about that DUID, consequently it ignores the requests:
/var/log/dnsmasq.log:
Jan 12 15:54:36 dnsmasq-dhcp[3780]: DHCPSOLICIT(eth0)
00:03:00:06:06:2d:4a:00:08:47 ignored
[...]
I'ld really appreciate any suggestions how to get IPv6 provisioned.
Thanks in advance!

Hello,
I do not use IPv6, partly because support for it in ACS is very poor.
Someone more experienced may be able to advise further.
One way I know people do it is to just enable router adverts on the shared VLAN, however this is very basic and unmanageable by Cloudstack.
I know several people are interested about making IPv6 happen and I am confident it's going to happen soon(tm):
