OpenNebula Systems has released version 7.2 of its open-source cloud and edge computing platform, a major update targeting sovereign cloud operators and organisations building AI factories at production scale.
The release, announced 7 April 2026 from the company’s Madrid headquarters, delivers three clusters of capability: deeper hardware integration for GPU-accelerated AI workloads, architectural improvements for scale and concurrency, and security enhancements for regulated environments.
Hardware integration
On the hardware side, OpenNebula 7.2 is now validated on NVIDIA Grace Blackwell GB200 systems (including VSwitch topologies), NVIDIA Spectrum-X networking platforms and NVIDIA BlueField DPUs. The NVIDIA Fabric Manager integration enables orchestration of NVSwitch and NVLink interconnects for multi-GPU topologies used in AI training and high-performance computing.
A new gRPC-based API replaces the previous communication layer between platform components, targeting lower latency and higher throughput in environments running large numbers of concurrent operations. Real-time virtual machine execution logs are now accessible directly through the Sunstone web interface, removing the need for command-line troubleshooting.
Security and storage
Security additions address sovereign cloud requirements directly. Confidential computing support now includes hardware-rooted trust and memory encryption for KVM workloads, complemented by virtual TPM integration. Administrators can enforce mandatory two-factor authentication globally within Sunstone.
Storage receives significant attention in this release. Virtual machines can be live-migrated between LVM and file-based datastores without downtime. Native integration with Everpure (formerly Pure Storage) FlashArray introduces full block storage lifecycle management. Incremental backup support for NetApp systems joins existing Veeam and oVirt API integrations.
Production-ready LXC drivers now provide VM-like lifecycle management for Linux containers, including network interface hot-plugging and disk snapshots. Enhanced VM Compatibility (EVC) improves workload portability across heterogeneous hardware, reducing migration friction during refresh cycles.
