DNS Manager is a fully automated DNS management service designed for virtualization of cloud environments. You can set DNS Manager on virtual machines in less than 5 minutes.

This document covers general recommendations for DNS Manager.

You can always install DNS Manager via Command Line Installer! This will work even if the server is virtualized with any another technology than Virtuozzo or if you do not have root access to the virtualization OS.

We recommend virtualization because it brings management advantages, as well as superior resource abstraction and disaster recovery capabilities.

Before you start to upgrade mission critical production environments, it's always safe to perform the testing phase.


DNS Manager can be installed on Red Hat Enterprise Linux 6/7 (x86_64) or CentOS 6.x/7.x (x86_64).

When the OS runs on a virtualization layer, we recommend VMware Vsphere or Virtuozzo.

Before you start the installation, make sure you review the Hardware Compatibility List.
