Product
In August, our team worked hard on preparing version 7.2, which brings several improvements to the Enterprise Cloud. Many of these enhancements are designed to meet the needs of companies migrating from VMware. In addition, some selected features will be backported to the upcoming 7.0.1 release.
Some of the progress highlights include:
- Sunstone updates: Based on feedback from 7.0 users, the interface has been refined for a smoother look and feel, and the code has been further stabilized.
- Incremental backups: LVM Thin now supports incremental backups, making data protection faster and more efficient. Ceph drivers introduce backup flattening for improved reliability, and NetApp drivers will support incremental backups in 7.0.1.
- Veeam integration: Enhanced with incremental backup support, along with improved stability and performance.
- Enhanced local drivers: A new multi-tier cache system at both host and cluster level improves image transfer times in hybrid deployments and large datacenters.
- vTPM support: Completed and ready for the next release, adding enhanced security capabilities.
- OpenNebula Cluster API (CAPONE): Updated with a new storage interface (CSI) for storing pod volumes in OpenNebula datastores.
- Quota system improvements: Administrators can now set up PCI quotas for better resource control.
We’re also developing new features to better integrate OpenNebula with NVIDIA accelerated infrastructure—such as DPU BlueField-3 and B200 GPUs—and to provide an open platform for both inference and training. These efforts aim to enable the next generation of Sovereign AI Factories.
Stay tuned—we’ll be sharing more updates on the 7.2 roadmap very soon!
Innovation
OpenNebula Systems is proud to introduce the OpenNebula MCP Server, a new AI-powered co-pilot that transforms how organizations manage their cloud environments. By leveraging the Model Context Protocol (MCP)—a pioneering open standard that enables Large Language Models (LLMs) to interact with external systems and APIs—the OpenNebula MCP Server allows users to translate simple, natural language instructions into complex cloud operations. This advancement represents a significant step toward more intuitive, accessible, and intelligent infrastructure management. Read the full blog and watch the detailed screencast here.
OpenNebula unveiled a game-changing move: its latest ARM64 support in version 7.0 “Phoenix” enables a Raspberry Pi 4 to morph into a miniature, enterprise-grade private cloud. With just a Raspberry Pi (4 GB or 8 GB RAM), Ubuntu Server 24.04 ARM, KVM, and MiniONE installer, you can spin up lightweight virtual workloads through the Sunstone interface—no bulky hardware required. This clever setup levels the edge-computing playing field by enabling developers, educators, and remote deployments to test and deliver infrastructure where it really counts. Learn more.

Knowledge Base Articles
Exclusive Resources for OpenNebula Subscribers
This month’s spotlight is on a practical configuration guide:
How to Configure Local Storage Datastore Using Sunstone.
In many OpenNebula deployments, administrators combine different types of storage backends to balance performance, cost, and flexibility. One particularly useful setup involves leveraging the local disks of each host to run VMs, while also maintaining a dedicated storage area for the VM disk image repository.
This article provides a detailed walkthrough of the steps needed to properly configure both System and Image datastores with local storage using the Sunstone web interface. You’ll find clear, step-by-step instructions on:
- Creating a new System datastore with the Filesystem – SSH mode backend.
- Associating the datastore with a cluster.
- Configuring additional datastore attributes as needed.
- Setting up a new Image datastore, ensuring it’s compatible with the previously created System datastore.
By following this guide, administrators can quickly enable efficient use of local storage resources while ensuring compatibility between system and image datastores. This configuration can be especially beneficial for scenarios where minimizing external dependencies and maximizing host-local performance are key requirements.
