Welcome to our newsletter! Dive into this edition to catch up on our latest updates, event highlights, future plans, and more.

Product

We’re excited to announce the release of OpenNebula 7.0.1, a feature-rich update that deepens enterprise and AI cloud capabilities on top of the foundation laid by 7.0. This release fuels our trajectory toward being the leading platform for AI factories and hybrid clouds.

Some highlights:

• GPU enhancements: We now support GPU monitoring (metrics like utilization, memory, temperature) and NVIDIA MIG (multi-instance GPU) to boost performance isolation.
• Storage and backup upgrades: Multi-tier caching (SSD/NVMe fronting slower storage), incremental backups across Ceph, LVM, NetApp, and native Veeam integration—these improvements help reduce I/O bottlenecks and improve data protection.
• Stronger security and identity: Virtual TPM support for VMs, along SAML 2.0 for federated login and SSO, make OpenNebula more enterprise-ready.
• Cloud-native / container integration: We now ship a CSI driver for Kubernetes, enabling dynamic volume provisioning and smoother hybrid VM/container workflows under a unified control plane.

In short: 7.0.1 isn’t just a maintenance release—it’s a strategic upgrade. It enables better performance, stronger isolation, tighter integration across architectures, and enhanced security—all key for customers running AI workloads, hybrid systems, or edge deployments. View the full details here.

Additionally, intensive development is already underway on the next release, OpenNebula 7.2, which will deliver even greater capabilities, scalability, and hardware integration, including:

• Advanced GPU functionality, with full integration of NVIDIA NVLink/NVSwitch for multi-GPU configurations.
• Certification for NVIDIA Spectrum-X, ensuring seamless support for AI and HPC networking fabrics.
• Optimizations to the LVM driver, enabling the use of SAN appliances without relying on intermediate storage layers.
• Storage Live Migration for seamless data mobility across nodes.
• Enhanced CPU compatibility (EVC) to simplify workload migration across heterogeneous hardware environments.

Beyond these updates, OpenNebula Systems provides enterprise-grade services—including deployment, certified training, 24/7 premium support, as well as migration from VMware and other tools to help bring your infrastructure to the next level. You can reach out to discuss your specific situation and discover how seamless the process can be.

Enterprise Alliances

We’re strengthening our technology alliances with key industry players—including NetApp, Veeam, Canonical, and Red Hat—as we move toward a more unified and resilient cloud infrastructure. Meanwhile, our ongoing collaboration with NVIDIA, including new certifications on their latest systems like GB200 and GB300, continues to empower organizations in building and managing sovereign AI Factories. Stay tuned—more exciting partnerships are on the horizon.

Innovation

OpenNebula has been officially integrated into Sylva 1.5.0, the open source framework driving the next generation of sovereign telco cloud stacks in Europe. This update enables full support for CAPONE (Cluster API) and CPI (Cloud Provider Interface) APIs, allowing seamless Kubernetes cluster lifecycle and runtime management on OpenNebula. This milestone reinforces our commitment to building open, interoperable, and sovereign digital infrastructure, aligned with the IPCEI-CIS Reference Architecture and the evolving needs of telecom and edge ecosystems.

Experiences

We’re proud to announce that OpenNebula Systems has joined CISPE’s working group on European sovereign-cloud solutions. With this step, we strengthen our strategic alignment with EU initiatives like the IPCEI‑CIS and bolster our role in shaping cloud architectures built to deliver transparency, interoperability, and vendor-lock-in freedom. As part of this initiative, we will bring our deep expertise in open source, hybrid and edge cloud deployments to drive scalable, federated infrastructures that support Europe’s data-sovereignty objectives. This engagement underscores our commitment not just to technology leadership, but to enabling a cloud ecosystem where sovereignty and innovation go hand-in-hand. See the full details here.
