Taking OpenNebula for a Test Drive

You can quickly and easily try out OpenNebula’s functionality by installing miniONE. Then, you can follow tutorials to quickly install an OpenNebula cloud.

Installation

For information on installing OpenNebula, please see this documentation section.

It is very useful to learn where log files of the main OpenNebula components are placed. Also check the reference about the main OpenNebula daemon configuration file.

Front-end Installation

The Front-end is the central part of an OpenNebula installation. This is the machine where the server software is installed and where you connect to manage your cloud. It can be a physical node or a virtual instance.

Please visit the official documentation for more details and a step-by-step guide. Using the packages provided on our site is the recommended method, to ensure the installation of the latest version and to avoid possible package divergences with different distributions. There are two alternatives here: you can add our package repositories to your system, or visit the software menu to download the latest package for your Linux distribution.

If there are no packages for your distribution, please check the build dependencies for OpenNebula and head to the Building from Source Code guide.

Node Installation

After the OpenNebula Front-end is correctly set up, the next step is preparing the hosts where the VMs are going to run. For details please refer to the installation guides for KVM Nodes and LXC Nodes.
