Get our comprehensive Kubermatic Virtualization vs Nutanix AHV comparison
After Broadcom’s changes to VMware licensing, many organizations are looking for alternatives. Nutanix AHV, part of Nutanix Cloud Infrastructure (NCI), is one popular option for running virtual machines.
Another option is Kubermatic Virtualization, which runs virtual machines on Kubernetes using the open-source KubeVirt project. This approach lets organizations run VMs alongside containers and AI workloads on the same platform.
This page compares Kubermatic Virtualization with Nutanix AHV (Acropolis Hypervisor).
Why teams look for a Nutanix alternative
Nutanix is a mature, well-supported platform, and for many teams it’s an easy landing spot after VMware. Teams usually start looking further when one of these concerns comes up:
Dependence on one vendor’s stack. AHV runs on Nutanix-certified hardware, and its storage, networking, and management tools are designed to work together as an integrated platform. Support for external storage such as Dell PowerFlex and Everpure offers more flexibility, but the overall platform remains closely tied to Nutanix’s ecosystem.
Full Kubernetes costs extra. Nutanix sells Kubernetes as a separate product: Nutanix Kubernetes Platform (NKP). A basic version is included only with the higher Nutanix Cloud Infrastructure plans, and the full versions are paid add-ons. To manage Amazon EKS or Azure AKS clusters, you need the top edition: NKP Ultimate.
Proprietary software from a US vendor. AHV and NKP are proprietary products licensed under Nutanix’s EULA. As a US-based vendor, Nutanix may raise data sovereignty considerations for organizations operating under European regulations.
Kubermatic Virtualization: the Kubernetes-native alternative to AHV
Kubermatic Virtualization is built for organizations looking to move away from VMware and bring virtual machines and containers onto the same platform. Rather than managing a separate hypervisor, your VMs run directly in Kubernetes using the open-source project KubeVirt. Your team can manage VMs, containers and AI workloads with one set of tools, instead of switching between separate systems.
If you’re moving away from VMware following Broadcom’s licensing changes, Kubermatic gives you a clear path to migrate your existing vSphere VMs. You can manage migration directly from the Kubermatic Virtualization dashboard using Forklift. It supports both cold migration, where the VM is shut down before moving, and warm migration, where data is copied while the VM keeps running. With warm migration, only the final switchover requires a short stop.
For AI workloads, VMs can access NVIDIA GPUs through GPU passthrough or vGPU, depending on your hardware and configuration.
It includes:
- KubeVirt to run VMs alongside containers on Kubernetes
- Kube-OVN for VM networking, with isolated virtual networks (VPCs) per tenant
- KubeOne for automated bare-metal provisioning on standard servers
- Installer and central management console for VMs and containers
- High availability and live migration, so VMs restart automatically on a healthy host and move between hosts without downtime
- Multi-tenancy and zero trust, with role-based access and automatic policy enforcement through Kyverno
- Data protection through Kubernetes-native backup tools and partners such as Portworx and Trilio
- 24/7 support on Enterprise plans
In production, the same open-source stack powers Swisscom’s sovereign Kubernetes Service: 390 clusters and 2,100 worker nodes in Swiss data centers, with customer data kept in Switzerland. The CNCF has published the architecture as a case study.
Where Nutanix falls short
VMs and Kubernetes - two platforms to manage: With Nutanix, VMs run on AHV, while Kubernetes runs separately on NKP. Each has its own tools, licensing and way of working, which adds complexity for teams managing both.
Kubermatic Virtualization brings VMs and containers together on one Kubernetes platform. Your team can manage both through the same API, policies and GitOps workflows, without switching between separate platforms.
The same principle applies to other hypervisors running alongside Kubernetes, as we explain in Proxmox vs KubeVirt.
You’re tied to the Nutanix ecosystem: AHV is designed to run as part of one integrated Nutanix stack on certified hardware. Kubermatic Virtualization runs on standard servers with any Kubernetes-compatible storage, so you can reuse hardware you already own and change hardware or storage vendors later without changing your platform.
The hypervisor is proprietary, not open source: Nutanix is designed to work as an integrated stack, with AHV running on certified hardware. This can limit your choice of hardware and storage.
Kubermatic Virtualization runs on standard servers and works with any Kubernetes-compatible storage. You can keep using the hardware you already own and switch vendors whenever you need to, without changing your virtualization platform.
No published prices: Nutanix licenses NCI per physical CPU core and doesn’t publish list prices, so costs depend on negotiation and renewal terms. Kubermatic Virtualization’s plans and prices are published, starting at €149 per month, and every plan includes the full feature set, so you choose by size and support level.
Data sovereignty concerns: Nutanix is a US-based company, which can raise data sovereignty concerns for European organizations. Even if your data stays in Europe, using software from a US company can raise questions about US legal jurisdiction, including the CLOUD Act.
Kubermatic is headquartered in Hamburg, Germany, and Kubermatic Virtualization runs fully self-hosted on your own servers. This gives you greater control over where your data is stored and helps address data sovereignty requirements.

Managing Kubernetes: KKP vs NKP
Nutanix offers Nutanix Kubernetes Platform (NKP), while Kubermatic offers Kubermatic Kubernetes Platform (KKP). Both manage multiple clusters across on-premises and public cloud infrastructure. The main difference is architecture: KKP runs each cluster’s control plane as pods on a shared management cluster instead of on dedicated VMs, so you can run many more clusters on the same infrastructure.
If you’re already using Nutanix, you don’t have to replace everything at once. KKP can manage Kubernetes clusters on your existing Nutanix infrastructure, as well as in public clouds, without requiring NKP licences. You can then move your VMs to Kubermatic Virtualization when it makes sense, for example when your Nutanix subscription is up for renewal.
Which platform is right for you?
Choose Kubermatic Virtualization if you:
- want VMs and containers on one Kubernetes platform, not a hypervisor with Kubernetes added on top
- want to run on standard servers and storage of your choice
- prefer open-source, upstream technology over a proprietary hypervisor
- want transparent pricing you can check upfront
- have strict data sovereignty requirements and want to keep your infrastructure fully self-hosted
Nutanix AHV may be the better fit if you:
- have already invested heavily in Nutanix infrastructure
- mainly run VMs and have limited plans to adopt Kubernetes
Conclusion
Nutanix AHV is a capable hypervisor, but it comes with trade-offs.
VMs and Kubernetes run on separate layers in Nutanix, leaving teams with two stacks to manage. By contrast, Kubermatic Virtualization brings VMs, containers and AI workloads together on one open-source Kubernetes platform.
For organizations looking to move away from VMware, Nutanix risks trading one form of vendor lock-in for another. Kubermatic, on the other hand, offers an open alternative that runs on standard servers with your choice of compatible storage, giving you greater infrastructure flexibility and transparent pricing.
Beyond infrastructure flexibility, data sovereignty is another important consideration. As a US-based vendor, Nutanix can raise concerns about US legal jurisdiction, even when data stays in Europe. Kubermatic, by comparison, is headquartered in Germany and offers a fully self-hosted solution, giving organizations greater control over their infrastructure and data.
