I’d recommend TKL Core + Bind9. DNS is a very small addition to a server which is my only guess as to why there isn’t a prebuilt TKL vm. Just run apt-get install bind9. TKL has packaged the Bind8 webmin module which I assume would work fine with Bind9. I think you would enable the webmin module within webmin itself. Personally, I just modify the files with an editor.
