OpenNebula

The Open Source Company Behind the Enterprise Cloud & Virtualization Platform OpenNebula 🚀

OpenNebula is a powerful, but easy-to-use, open source Cloud & Edge Computing Platform. It provides a production-ready solution that combines VMware and KVM virtual machines with LXC containers and Firecracker microVMs, on top of which you can run complex multi-VM services, orchestrate application containers or deploy dynamic Kubernetes clusters. Thanks to its Hybrid and Edge connectors, OpenNebula allows you to grow your Enterprise Cloud or DevOps infrastructure on-demand avoiding vendor lock-in, automatically provisioning resources from different public cloud and edge providers, including Amazon Web Services (AWS), Equinix Metal and—very soon—several 5G providers plus the European virtual hyperscaler GAIA-X.

Look back at NVIDIA GTC Berlin with us 👀
Following OpenNebula's recent NVIDIA AI Cloud Ready validation and deep integration with the NVIDIA ecosystem, we were excited to bring our latest AI Factory solutions to Berlin.

GPUaaS and Kubernetes-based platforms alone don’t provide the full infrastructure management an AI Factory needs.

At , we showed how OpenNebula fills that gap with an open source platform designed to build and operate sovereign AI clouds, from bare metal to production-ready AI services.

How can you get more out of your GPUs without leaving expensive capacity idle? Here’s how OpenNebula can help 👇

A pharmaceutical company needs GPUs for inference during the day and AI training overnight. As inference demand drops, its platform team reallocates eligible GPU capacity to training VMs or Slurm workers.

The result? Better GPU utilization across different services.

This is one of 10 practical use cases in our latest blog post that explores why the infrastructure operating model matters when building and operating an AI Cloud.

We’re happy to announce a new collaboration between OpenNebula Systems and Axelera AI to advance end-to-end infrastructure for European sovereign AI.

The collaboration builds on our existing integration of Axelera AI’s Metis® AIPUs and aims to expand the evaluation of Axelera AI’s Europa® products.

For us, this is about more than technology. This is a strategic leap for the open European AI ecosystem, giving organizations real choice and control over how they deploy and run AI, from enterprise environments to AI Factories.

We thank the Axelera AI team for their collaboration and for supporting this effort.

What makes OpenNebula a good alternative to VMware?

Replacing VMware doesn’t mean giving up the virtualization features you rely on. With OpenNebula, you can keep familiar capabilities, adapt the platform to your needs, and preserve your existing hardware investments.

But don't just take our word for it!

In our recent webinar, we sat down with TrueFullstaq to hear why they chose OpenNebula as their VMware replacement and how the transition has gone so far.

Meet our blueprint for building sovereign AI Factories with , NVIDIA, and .

Europe is paying more attention to tech sovereignty, and for good reason. If we want more control over our cloud and AI infrastructure, we need to think about the technology it runs on.

Our blog post combines NVIDIA-accelerated infrastructure, NetApp’s data platform, and OpenNebula’s open source control plane to help Neocloud providers build sovereign AI Factories that run diverse workloads while keeping data available and infrastructure under their control.

We're happy to share that Talos Kubernetes is now available as a native OpenNebula service!

Developed by our partner TrueFullstaq, the open source talos-opennebula integration uses OpenNebula's OneFlow and OneGate capabilities to simplify the deployment and management of Talos Kubernetes clusters.

Thanks to this, teams can benefit from:
✅ Simplified cluster deployment and lifecycle management
✅ Repeatable deployments with less operational overhead
✅ Minimal, immutable nodes designed for Kubernetes

The integration complements OneKS, OpenNebula's Kubernetes service, and offers another option for teams that specifically want to run Talos.

One last day to catch the team at NVIDIA GTC in Berlin! Have we met yet? 👀

We’re making the most of our final day and showing how cloud elasticity can make AI and HPC infrastructure more flexible.

💡 Have you checked out our demo yet? See how OneSlurm brings cloud elasticity to Slurm-based environments, letting operators deploy isolated clusters on demand and scale compute and GPU capacity as workloads change.

If you’re working with AI or HPC clusters and looking for more flexible ways to manage resources, this is a demo worth checking out!

📍 See you at booth 7031
