Webmin/Virtualmin when enabling bind:
Failed to save enabled features : Virtualmin is configured to setup DNS zones, but this system is not setup to use itself as a DNS server. Either add 127.0.0.1 to the list of DNS servers, or turn off the BIND feature on the module config page.
It means what it says, add "127.0.0.1" to /etc/resolv.conf........
