Forum post https://www.virtualmin.com/node/66569 has complete details as I am currently unsure if this is a feature request or a bug.
I am attempting to use the powerDNS plugin for Virtualmin and it only seems to partially work. It creates the zone in PowerDNS when you enable the module on a domain, however, Virtualmin does not show the DNS zone editor in the Virtual Server. It provides the "suggested DNS records" option instead of the "DNS Options" and "DNS Records" option to actually control the DNS records when using PowerDNS.
Is this an issue in the PowerDNS module because it is no longer maintained or something in the Virtualmin core?
