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.
