Question How to make permanent IPV6 configuration - Cloud init

[tanzo.it]

Hello to all, I'm struggling with this problem, I've setted the IPV6 configuration (OVH VPS) in this file: /etc/sysconfig/network-scripts/ifcfg-eth0
but, at every reboot the configuration is resetted, how to make it permanent?

This is the first line of the configuration file:
# Created by cloud-init on instance boot automatically, do not edit.

(I know it says do not edit, but at moment I don't know how to apply this new configuration in other ways)

Plesk
Plesk Onyx v17.5.3_build1705170317.16 os_CentOS 7

OS
CentOS Linux release 7.4.1708 (Core)

Kernel
3.10.0-693.17.1.el7.x86_64

Thanks to all.

Thanks for reply Mark, but this didn't help me, I always edited the file and stop. I wouldn't learn cloud-init only for set an IPV6
There is a short way?

Thanks a lot.
