</span>Apparently you are passing in the 'custom_script' some DNS<br>
configuration, which may conflict with the DNS configuration that you<br>
are passing in the 'dns_servers' and 'dns_search' options. It could be<br>
that cloud-init ignores one of them. I'd suggest that you try to remove<br>
completely the 'custom_script' parameter.<br>
