OpenNebula Systems has released OpenNebula 7.2, an update designed for sovereign cloud environments and AI factories, with enhancements to automation, security and orchestration for AI, high-performance computing (HPC) and regulated cloud deployments.
As AI workloads move into production, infrastructure is required to support reliable operations, hardware integration and flexible execution models. OpenNebula 7.2 introduces expanded orchestration capabilities for GPU-accelerated and high-speed networking environments, supporting large-scale AI workloads.
The release includes architectural updates aimed at improving performance, concurrency and observability. A new gRPC-based API enables low-latency, high-throughput communication between platform components, while real-time virtual machine execution logs are available through the Sunstone interface to support troubleshooting without command-line access.
OpenNebula 7.2 integrates with NVIDIA technologies including Fabric Manager, NVSwitch and NVLink interconnects to support orchestration of AI training and HPC workloads. It also supports NVIDIA Spectrum-X networking platforms, enabling low-latency ethernet for large-scale AI systems and supporting multi-tenant deployments through network offloading and isolation capabilities.
Workload portability is improved through Enhanced VM Compatibility (EVC), supporting migration across different hardware environments. Networking updates include IP address sharing for virtual machine groups to support multi-tier application deployment.
Security updates focus on sovereign and regulated environments, including hardware-rooted trust, memory encryption for KVM workloads and virtual TPM support. The release also introduces mandatory two-factor authentication within Sunstone to enforce consistent access controls.
Storage enhancements include improved mobility and data protection, integration with Everpure (formerly Pure Storage) FlashArray for block storage lifecycle management via API, and optimisations such as LVM tuning, multi-tier caching and incremental backup support.
OpenNebula 7.2 also introduces OneForm, a service for automated deployment and configuration of clusters, alongside expanded support for enterprise Linux distributions including SUSE Linux Enterprise, AlmaLinux, OpenSUSE and Debian.
