IPv6 with VIO 5.1 VDS

[dalo]

I'm trying to get IPv6 working with a VDS deployment, but the DHCP doesn't deliver a IPv6 IP.

If I create a server with v4 and v6 I got only a v4 IP. If I assign a v6 IP the connection over v6 works too.

But I want to deploy a server with only IPv6, because v4 IPs are rare.

I contacted the support and get the answer "we do not support IPv6 on a VDS deployment". This is really annoying, because in my opinion this is really a important "feature" today in a cloud environment.

I'm trying now to setup the IP via user-data, but this fails because the Linux guest customization relies on a IP connection to 169.254.169.254.

Does anybody can help me with this, to assign the IPv6 in the guest to the IP automatically selected from VIO?

I could solve this:

Use (only) "config drive" for metadata, delete additional network config in /etc/cloud/cloud.cfg.d/ on the guest OS.

Setup a IPv6 Network and a subnet with "--no-dhcp"

Crate a server with: "--config-drive true"
