OpenNebula supports the automated deployment of Kubernetes Clusters through OneKS, the OpenNebula Elastic Kubernetes Service. OneKS provides Kubernetes-as-a-Service on top of OpenNebula, offering a structured way to create, access, operate, scale, upgrade, recover, and deprovision Kubernetes Clusters across cloud and edge environments. It combines a user-facing service layer with Cluster API-based infrastructure provisioning through CAPONE, the Cluster API provider for OpenNebula.

### Accelerated Computing for AI and HPC

OpenNebula provides native integration with accelerated hardware architectures from multiple vendors facilitating AI and HPC workloads. OpenNebula's accelerated computing capabilities include full compatibility with NVIDIA Hopper and Blackwell GPUs, flexible GPU allocation with passthrough, vGPU and MIG, GPU scheduling, optimized multi-GPU communication with enhanced networking, DPU integration and multi-tenant, bare-metal AI Factory-scale infrastructure management with NVIDIA NIco. OpenNebula further supports pre-built inference applications and native integration with frameworks and platforms such as vLLM, Hugging Face, Run, and NVIDIA Dynamo for the deployment, scheduling, orchestration, and monitoring of AI and LLM workloads.

### Management Model and Tools

OpenNebula’s management model provides multi-tenancy by design, offering different user interfaces depending on users’ roles within an organization, or the level of required expertise or functionality.

* **Completely Redesigned Interface** — A new design system built on a systematic usability audit delivers a cleaner, more consistent visual language with improved information architecture, updated typography, and a refined colour palette that scales across screen sizes and devices.
* **Redesigned Settings and Navigation** — The application structure has been reorganized from the ground up. A new settings experience and clearer navigation hierarchy make it faster to find what you need and easier to understand where you are in the app.
* **New Item Exploration via Side Drawer** — Resources can now be inspected without leaving the current context. A new slide-in drawer lets operators quickly explore the details of any item — VMs, hosts, networks — without losing their place in the workflow.

* **Richer Resource Visualization** — Individual resource views have been redesigned to surface the most relevant information upfront, reducing the need to dig through tabs to get a clear picture of an item's state, configuration, and relationships.
* **Added FSaaS (VirtioFS) Support** — Users can now manage shared storage file systems, create filesystem images, and attach disks directly from the Sunstone GUI.
