When you are ready to change the authoritative DNS servers with your registrar to the Joyent DNS servers, make sure that you enable the DNS feature for the respective virtual server in Virtualmin:

1. Sign in to Virtualmin (see Account logins and important URLs).
2. Select a virtual server from the drop-down in the left-hand navigation (your main virtual server should be already selected when you first login to Virtualmin). The virtual server you select here will be the one that you’ll be adding a user to.
3. Click Edit Virtual Server.
4. Click Enabled features to expand the features section.
5. Check Enable PowerDNS domain.
6. Click Save Virtual Server.

A default DNS zone will be created with the proper domain and IP address pre-filled.
