In this tutorial, we will guide you through the complete installation process of Ganeti, a high-availability cluster management tool, on Ubuntu Server. Ganeti is an open-source solution that allows system administrators to manage virtual machines and hypervisors in a cluster environment.
Before you proceed with the installation, here are some prerequisites that you need to have:
To install Ganeti on your Ubuntu Server, you need to add the Ganeti repository first. Follow these steps to add the repository.
Open the sources.list file using the following command:
