In this screencast we will walk through the installation process using the MiniOne OpenEBOLA deployment tool. MiniOne is the tool to quickly and hassle-free install OpenEBOLA for evaluation purposes either as a front-end only deployment, meaning that only the control plane is going to get installed, or alongside with a hypervisor node. It is recommended to use MiniOne on a server with exposed hardware virtualization, however for evaluation purposes QE mobilization is available. MiniOne is going to automatically detect and add a hypervisor as a KVM or QEMU node. MiniOne deployment is easily expandable should you need to. In the future you can add more hypervisor nodes whether these are LXE or KVM. You can find more information about MiniOne in the official OpenEBOLA documentation. This particular page can be accessed by expanding the Getting Started, Quick Start, OpenEBOLA Deployment, MiniOne Deployment, or by using the search provided by the documentation engine. In this demonstration we are going to use this page as our guide. For starters, we must download the MiniOne tool. We are going to create a dedicated directory for this purpose in the home directory of a root user, let's name it deployment, and then download the MiniOne tool into the newly created directory. Add the execution bit for MiniOne script. There are some flags that you can find useful. For example, using the password flag to set the specific password for OpenEBOLA's one admin user instead of a randomly generated string. Or only install the control plane, also known as frontend-only deployment, by appending the frontend flag. By default MiniOne is going to install the latest and greatest version of OpenEBOLA, however you may append the version flag to install the desired version instead. In the scope of this demonstration we are going to proceed with frontend and KVM deployment of the latest version at the moment of recording, with a custom password. By default MiniOne is going to import the virtual machine template and image of Alpine Linux 3.20 from the official OpenEBOLA marketplace. This obviously can be overridden. Please be patient as it may take a while. Once the installation is done, you are going to see the output containing the URL, password and username of the graphical web UI. Note that the official port of SunStone web UI, unless proxied, is 2616 TCP, however MiniOne by default is going to bind it to 80 TCP. This can be overridden should you need to. Let's connect to SunStone and log in using the printed out credentials. Once logged in, you are welcomed with a typical OpenEBOLA dashboard containing four shortcuts and a left-hand menu. By clicking the VM templates you can find the Alpine Linux template. A similarly named image can be found under the Storage – Images. There is going to be one routable virtual network created. You may change the DNS server should you need to. There is also one KVM host to run virtual machines. Let's deploy a VM, navigate to Instances – VMs and press Create. Select the Alpine Linux 3.20 template and name it the way you wish. It's going to take a while before the VM is running. Open the VNC console and log in using root as the user and OpenEBOLA or lowercase as the password. As seen on the screen, the virtual machine is running as expected. Once the virtual machine is no longer needed, terminate it by pressing the trash bin icon and selecting the Terminate option. For faster deletion, you may select the Hard option instead. And this concludes the screencast where we have shown how to use the MediaOne tool to install OpenEBOLA with a hypervisor on a single node. Also, we have verified that the environment is ready to run workloads by instantiating the Alpine Linux virtual machine template. Thank you for watching and see you in the next screencast.

TL;DR

miniONE is a hassle-free deployment tool for quickly installing OpenNebula for evaluation purposes, supporting both frontend-only and hypervisor node configurations with automatic KVM/QEMU detection.
Installation involves downloading the miniONE script, setting execution permissions, and running with optional flags for custom passwords, specific versions, or frontend-only deployment on port 80 by default.
The deployment automatically imports an Alpine Linux 3.20 VM template from the OpenNebula marketplace and creates a routable virtual network, providing an immediately functional environment for testing workloads.

Summary

This technical demonstration walks through the complete installation process of OpenNebula using the miniONE deployment tool, designed for quick evaluation deployments. The screencast covers downloading and configuring miniONE, executing the installation with custom parameters including password settings and version selection, and verifying the deployment by launching an Alpine Linux virtual machine. The tutorial demonstrates both frontend-only and hypervisor node installation options, showing how miniONE automatically detects and configures KVM or QEMU virtualization. Viewers learn to access the Sunstone web interface, navigate the dashboard, manage VM templates and images, configure virtual networks, and perform basic VM lifecycle operations including instantiation and termination. The demonstration emphasizes miniONE's ease of use for evaluation purposes while noting that deployments can be expanded with additional hypervisor nodes in the future.

FAQ

What are the hardware requirements for running miniONE?

miniONE is recommended for servers with exposed hardware virtualization capabilities, though QEMU virtualization is available for evaluation purposes when hardware virtualization is not accessible. The tool automatically detects and configures the appropriate hypervisor type.

Can I expand a miniONE deployment after initial installation?

Yes, miniONE deployments are designed to be easily expandable. After the initial installation, you can add more hypervisor nodes including both LXE and KVM types to scale your environment beyond the single-node evaluation setup.
