I have also considered simply running both as a primary DNS and just cloning one to the other, rather than running a primary and a secondary since they will always be mirrors of each other.

I'm assuming you are hosting the virtual sites on the primary dns box? Is "Automatic DNS Configuration" ticked in the virtual host template? Are the required hostnames entered in the "Auto DNS" tab of Network Services > DNS? With those two configurations your primary dns is populated automatically at site creation.

Populating the secondary dns box is what "secondary" dns does... Make sure the IP address of the secondary box is entered in the "Advanced" tab of DNS Settings on the primary box -- "Zone Transfer Access by IP Address" field. This tells primary dns the secondary box is allowed to ask for and receive zone files for domains hosted on the primary box.

So, you end up with two manual operations at site creation -- creating the vhost on the primary box, and creating secondary dns service on the secondary box (Edit Secondary Services in DNS). All subsequent changes are duplicated on the secondary box after zone transfer.

It has been a while since I used my BQ/BX box for dns, and I'm not sure if BX supports the NOTIFY method on the primary side (where a change in the primary zone file would trigger a "push" effect to secondary), but zone transfer interval gets the secondary in sync in due time.

Is that what you are asking?
