Cluster Installation on

Overview

Wed, 15 Apr 2026 00:00:00 +0000

OpenNebula Clusters are logical groupings of Hosts, datastores and Virtual Networks that provide compute capacity for cloud workloads. Cluster compute resources can consist of on-premise servers or virtual or bare-metal instances from a 3rd-party IaaS provider.

Before deploying OpenNebula Clusters, you must deploy an OpenNebula Front-end. If you have not already deployed a Front-end, refer to the Front-end Deployment Documentation for details.

Once you have successfully deployed an OpenNebula Front-end, you can proceed to manually install or automatically create (provision) Clusters to handle cloud workloads. There are three options:

Automatic Cluster Provisioning with OneForm

Wed, 15 Apr 2026 00:00:00 +0000

OneForm is OpenNebula’s automated cloud provisioning tool. It serves as an automated “cloud-on-demand” engine, allowing you to provision resources on-premises, or bare-metal instances from public cloud providers through a simple, streamlined workflow. You can provision Clusters through an OpenNebula Front-end through the the Sunstone user interface, the OneForm CLI, or the OneForm REST API.

Before Starting

In order to use OneForm, you must first install an OpenNebula Front-end using one of the available deployment options, refer to the Front-end Installation Documentation for details.

KVM Node Installation

Mon, 17 Feb 2025 00:00:00 +0000

This page demonstrates how to configure an OpenNebula KVM Node from binary packages.

Note

Before installing a KVM node, you must have an OpenNebula Front-end deployed. Refer to the Front-end Deployment Documentation for details.

Overview

KVM (Kernel-based Virtual Machine) is the main virtualization solution for Linux on x86 hardware that contains virtualization extensions (Intel VT or AMD-V) and on ARM64 (currently in beta mode). It consists of the loadable KVM kernel modules (one that provides the core virtualization infrastructure and several processor-specific modules), but the complete KVM virtualization stack usually also contains the user-space machine hardware emulator QEMU accelerated by the KVM and Virtual Machines management tool libvirt.

LXC Node Installation

Mon, 17 Feb 2025 00:00:00 +0000

This page demonstrates how to configure an OpenNebula LXC Node from binary packages.

Note

Before installing a KVM node, you must have an OpenNebula Front-end deployed. Refer to the Front-end Deployment Documentation for details.

Overview

LXC is a Linux technology which allows us to create and manage system and application containers. The containers are computing environments running on a particular hypervisor node alongside other containers or Host services, but secured and isolated in their own namespaces (user, process, network).
