Following the architectural foundation laid by OpenNebula 7.0 “Phoenix,” we’re officially announcing the general availability of OpenNebula 7.2. While version 7.0 introduced the structural shift toward modern cloud management, 7.2 is the hardened, stable release designed for production environments requiring high concurrency, hardware-rooted security, and the deep GPU integration necessary for the modern enterprise.

Accelerated Infrastructure and AI Training

As AI workloads move from experimental to production, the underlying infrastructure must support more than just simple passthrough. OpenNebula 7.2 focuses on the interconnects and fabrics that define high-performance clusters.

• NVIDIA Fabric Manager Integration: Seamlessly orchestrate NVSwitch and NVLink interconnects to optimize multi-GPU topologies for large-scale AI training.
• Next-Gen Hardware Validation: We have officially validated compatibility with NVIDIA Grace Blackwell (GB200) systems and Spectrum-X networking platforms, enabling high-performance, low-latency ethernet fabrics optimized for AI clusters.
• DPU & Network Offloading: With validated integration for NVIDIA BlueField DPUs, OpenNebula 7.2 enables hardware-level isolation and network offloading, maximizing throughput in multi-tenant environments.

Architectural Performance at Scale

We’ve modernized the communication layers to handle thousands of concurrent operations and improved operational visibility for large-scale deployments.

• Next-Generation gRPC API: A modern gRPC-based API provides low-latency, high-throughput communication, significantly improving responsiveness in large infrastructures.
• Enhanced VM Compatibility (EVC): Simplify workload mobility across heterogeneous hardware. EVC allows you to define a common CPU baseline for a cluster, ensuring seamless live migrations between different CPU generations.
• Integrated VM Logs: Real-time VM execution logs are now available directly within the Sunstone GUI, streamlining troubleshooting for cloud admins without requiring CLI access.
• IP Address Sharing: New IP leasing for VM groups simplifies networking for multi-tier applications by reserving dedicated IP ranges for grouped workloads.
• Production-Ready LXC: Improved LXC drivers now provide VM-like lifecycle management—including NIC hot-plugging and disk snapshots—delivering container agility with near-native performance.

Security and Sovereign Cloud Compliance

For users building Sovereign Clouds, control must extend to the silicon. 7.2 introduces features that satisfy strict regulatory and security requirements.

• Confidential Computing & vTPM: Protect sensitive workloads with hardware-rooted trust and memory encryption in KVM. New vTPM support provides stronger workload integrity guarantees for mission-critical data.
• Enforced Multi-Factor Authentication: Security is only as strong as its weakest link. Administrators can now enforce mandatory 2FA globally across Sunstone, ensuring consistent security policies for every user.

Storage Flexibility and Enterprise Backups

Managing data at scale requires the ability to move and protect it without impacting service availability.

• Storage Live Migration: Migrate Virtual Machines between LVM and file-based datastores (shared or local) with zero downtime, enabling seamless storage rebalancing and maintenance.
• Enhanced Storage Performance: Multi-tier caching for local datastore drivers and major LVM backend tuning reduce storage bottlenecks and significantly improve I/O efficiency.
• Native Everpure (formerly Pure Storage) Support: A new native driver enables full block storage lifecycle management via the Everpure (formerly Pure Storage) FlashArray REST API.
• Efficient Backups: We’ve introduced incremental backup support for NetApp, alongside major improvements to Veeam and oVirt API integrations, drastically reducing backup windows.

Deployment and Ecosystem Support

To simplify the transition to 7.2, we’ve expanded our automation tools and OS compatibility:

• OneForm (Automated Provisioning): A new service designed for distributed environments that enables the automated deployment and configuration of OpenNebula clusters on demand.
• Broad OS Support: Official support now includes SUSE Linux Enterprise (SLE) 15, along with the latest versions of AlmaLinux 10, RHEL 10, OpenSUSE 16, and Debian 13.
