Help with manually configuring a static IPv6 network

By spikepike ·
Hi,

I have a private OpenStack environment which works fine apart from IPv6. I'm trying to setup an IPv6 network whereby 3 VMs can talk to each other over IPv6. The DHCP element is not working but I should apparently be able to statically configure. However I have no idea how to achieve this. Is this something someone can help with?
