LCM & one-click upgrades
- The Lifecycle Manager updates firmware and the software stack, including dependency management, largely automatically. Proxmox updates via apt - there is no integrated firmware management.
Proxmox as a Nutanix alternative
We compare capabilities and operating requirements, inventory AHV workloads, and plan the target architecture, pilot migration, cutover, and subsequent managed operations.
- No per-core licensing
- AHV & Proxmox share the KVM base
- Proven OVA migration path
Starting point
Why companies look for a Nutanix alternative
Technically, Nutanix is a mature HCI platform. The pressure comes from the licensing model - and from the opacity of its pricing.
Licensing per CPU core
Nutanix Cloud Infrastructure (NCI) is licensed as a subscription per physical CPU core - in the Starter, Pro and Ultimate tiers with terms of 1 to 5 years. The license must cover all cores in the cluster; Starter is also limited to clusters of up to 12 nodes, and a standard cluster starts at 3 nodes.
No public price list
Nutanix does not publish list prices - quote and renewal pricing is negotiated per project. You only find out how high the next renewal will be once the offer is on the table. For budget planning, that is a structural risk.
Scaling raises the license burden
Because the subscription must cover all physical cores in the cluster, the license burden automatically grows with every hardware expansion - regardless of what the new cores are needed for. With Proxmox VE you scale without a mandatory license.
From the field
Evaluated and rejected: NeoTel on Nutanix
Viennese telecommunications provider NeoTel faced the choice while replacing its VMware environment and evaluated Nutanix - and decided against it (proxmox.com case study, January 2026).
The reasoning
The reasoning is remarkably specific: Nutanix came "with strict licensing models and limited flexibility", and "certain expansions and feature updates required additional licenses".CEO of NeoTel, proxmox.com case study, January 2026 (translated)
"With Proxmox VE we can scale completely freely, at our own pace and without unforeseen licensing costs."Important context
NeoTel did not migrate away from Nutanix, but examined the platform during its selection process and rejected it. The outcome of that evaluation is nonetheless one of the clearest public statements on the Nutanix licensing model.
Comparison
Nutanix vs. Proxmox: what replaces what?
The stack can be mapped component by component - including the points where Proxmox works differently from Nutanix.
| Layer | Nutanix | Proxmox equivalent |
|---|---|---|
| Hypervisor | AHV - per the Nutanix Bible "based upon Linux, QEMU, and KVM" | KVM/QEMU - the same technical foundation. Your workloads are technically related; the move is not a platform break. |
| Management | Prism Central | PVE web GUI plus Proxmox Datacenter Manager (PDM 1.1) for cross-cluster management and cross-cluster migration. To be fair: PDM is a young 1.x product. |
| Storage | AOS/DSF - distributed scale-out storage | Ceph - scale-out storage with typically 3 replicas, integrated directly into Proxmox VE. |
| Licensing model | Subscription per physical CPU core for all cores in the cluster (Starter/Pro/Ultimate, 1-5 years) | No mandatory license - optional enterprise subscription per CPU socket. |

Migration path
How your VMs get from AHV to Proxmox
There is no official migration tool in this direction - Nutanix Move only migrates to Nutanix. The proven route runs via OVA export:
- 01
Export from Prism Central
For each VM we use "Export as OVA" in Prism Central - the archive contains the disks as QCOW2 or VMDK. Alternatively, we convert disks directly via acli and qemu-img.
- 02
Import into Proxmox VE
Unpack the OVA and bring it into PVE via qm importovf or disk import - the target storage is ZFS, Ceph or LVM, depending on the architecture.
- 03
Rebuild configuration & test
Nutanix offers no config export: we rebuild CPU, RAM, NICs and boot order manually in PVE, verify VirtIO drivers and test every VM before cutover.
Honest assessment
Where Nutanix is objectively stronger
An honest assessment is part of the deal: these three points speak for Nutanix - and this is exactly where our operations model comes in.
Integrated data services
- With Nutanix, Files, Objects and Volumes come from one platform. With Proxmox, you cover such services via separate components.
One vendor for everything
- Support for hardware and software from a single source, including certified NX appliances - one point of contact for the entire stack.
Managed Proxmox
We close exactly this operational gap
Firmware care, update orchestration, 24/7 proactive monitoring, backup management, and incident response: our team handles ongoing Proxmox operations as Managed Proxmox.
Managed Proxmoxfrom €179.90 excl. VAT / node and monthYou receive the migration itself as a fixed-price offer after the assessment.
Frequently Asked Questions
Answers to the most important questions
- For virtualization, HA clusters and scale-out storage: yes. AHV and Proxmox VE share the KVM foundation, Ceph replaces the distributed AOS/DSF storage, and the PVE GUI plus Proxmox Datacenter Manager cover management. What Proxmox does not bring in the same form are Nutanix extras such as integrated data services (Files/Objects/Volumes) and the automated one-click upgrades of the Lifecycle Manager. Whether the replacement is complete for you depends on which of those services you actually use - that is exactly what we clarify in the assessment.
- Via the OVA route: in Prism Central we export each VM using "Export as OVA" - the archive contains the disks as QCOW2 or VMDK. In Proxmox VE we import via qm importovf or disk import; alternatively, we convert disks directly with acli and qemu-img. We rebuild the VM configuration (CPU, RAM, NICs, boot order) manually, because Nutanix offers no config export. Since AHV, like Proxmox, is based on KVM, the guests keep running without a platform break.
- Your Nutanix subscription stays active until cutover - we plan the migration so it completes before your next renewal, so you do not risk paying twice. After that, the mandatory license goes away: Proxmox VE runs without a subscription; if you want vendor support and the enterprise repository, you purchase the optional per-socket subscription directly from Proxmox.
- The migration is a one-time project whose effort depends on VM count, storage volume and network complexity - you receive a fixed-price offer after the assessment. In ongoing operations, the per-core subscription disappears entirely; the per-socket Proxmox subscription remains optional. On request, we run the environment as Managed Proxmox from €179.90 per node per month.
- Viennese telecommunications provider NeoTel evaluated Nutanix while replacing its VMware environment and rejected it - due to strict licensing models and limited flexibility - opting for Proxmox VE instead (proxmox.com case study, January 2026). Other organizations such as University Medicine Essen also run Proxmox in production at scale.
- Yes. After cutover, your environment runs under managed operations on request: 24/7 proactive monitoring, updates in maintenance windows, backup management with Proxmox Backup Server, and incident response - Managed Proxmox from €179.90 per node per month. This also closes the operational gap left by Nutanix features like LCM.

Reviews & projects
Proxmox proof from real projects
Customer feedback on virtualization, backup, VPN, security and ongoing cluster operations.
WZ-IT moved our studio infrastructure from decentralised individual devices to a central platform: every site is securely connected via VPN, new devices are onboarded automatically and an entire site is provisioned from a template, without manual steps on location. What impressed me most is the breadth and depth of their knowledge: Timo and Robin are not a typical IT provider who sets up a server and leaves. The two of them think their way into highly complex infrastructure and software topics, work through every requirement we put in front of them, and build networking, provisioning and operations so that everything fits together in the end. WZ-IT is an excellent partner for complex software, network and architecture projects.
