Hi there,
I installed a few minor updates on two (so far) Proxmox hypervisors and suddenly all RHEL-related templates used seemed to have stopped working. The templates get cloned, boot up and they learn username+password from cloud-init, but then they don't learn any of the provided static IPv4 and IPv6 addresses. The exact same templates still work as before on the nodes that haven't yet been updated. On the non-updated nodes, you would just see the IPs in those ASCII-tables. On the updated nodes you see the below error output getting written to `/var/log/cloud-init-output.log` and just localhost IPs in the table. Seems somehow as if cloudinit doesn't know anymore how to handle static IPv6 addresses? The Debian/Ubuntu templates on the updated nodes however still work without any issues.
Did anybody else see such an issue and maybe has a fix/workaround for it?
Thanks,
Michael
EDIT: Looking at the source of `cloudinit/net/sysconfig.py`, `static6` seems to be a legit config value for cloudinit. Still have no clue whats going on here, so if there is anybody with an idea; I would really appreciate it.
