Hi

During creating shared network, there is not enter the IPv6, but now wish
to add in IPv6, is that possible ?

Understood.
I see a possibility where IPv6 details can be added to a network at a
later stage, but only if there is no IPv6 configuration in the network yet.
The problem is that IPv6 Router Advertisements will be allowed to be
send to the VMs and they will generate an address, but this will not be
allowed by the Security Groups.
So this will require some manual hacking in the database, I don't see
another way around it.

Hi Wido
It actually doesn't matter if the existing VM does not get the IPv6 after
it has altered, as the time they existing VM registered , it does not have
IPv6 . So it is understandable that new add-on IPv6 feature doesn't take
effect.
>> The best way is to create a new shared network and then migrate
Instances to that new IPv6-enabled network.
But if creating new network , the New SharedNework need also IPv4 which
will be conflict with the existing GuestNework range that need ipv4. If
creating new network that have other Ipv4, then mean all existing VM have
to change New IPv4, which a little bit hard to explain to existing VM
user for reasons of adding IPv6 need change IPv4

Yes, hacking the SQL table is currently the only way.
You will need to set the ip6cidr in the database and then make sure your
Router is sending out Router Advertisements.
But keep in mind that existing VMs won't get IPv6 by using this method.
The best way is to create a new shared network and then migrate
Instances to that new IPv6-enabled network.

Now, I have no way to add in IPv6 for existing shared networks . I think
many cloudstack users may experience the same issue .
The hack is to manual Edit MySQL tables ? but i am not really to do this
except no other alternatives .
May be anyone can give advice for some work around on this.
