Overview
Harvester is an open-source hyperconverged infrastructure platform that runs virtual machines and containers side by side on bare metal servers. It is built from existing cloud-native components, Kubernetes, KubeVirt, Longhorn and KVM, rather than a proprietary hypervisor, and was announced by SUSE's Rancher engineering team in 2020 following SUSE's acquisition of Rancher Labs.
The project positions itself as a free, open-source alternative to VMware vSphere and Nutanix, aimed at organizations that want to consolidate virtualization and Kubernetes infrastructure onto one platform without per-CPU licensing fees.
Key Features
Harvester installs directly onto bare metal via an ISO-based installer and presents a web dashboard for managing VMs, networking and storage without requiring Kubernetes expertise. VMs run as KubeVirt-managed workloads, so the same cluster can host legacy virtualized applications and native containers simultaneously.
Longhorn provides distributed, replicated block storage for VM disks without a separate SAN appliance, and Harvester integrates natively with Rancher, letting administrators provision downstream Kubernetes clusters directly from VMs running inside the platform. Support for VLANs, multiple network interfaces and live VM migration rounds out its feature set for production data center and edge use.
Pricing
Harvester itself is entirely free and open source with no licensing fees, purchase price or seat cost. Organizations pay only for the underlying hardware they deploy it on.
SUSE offers optional paid enterprise support, migration assistance and consulting for organizations that want SLA-backed help rather than relying on the community Slack channel and GitHub issue tracker, but no commercial license is required to run Harvester in production.
Key Features
Bare Metal Hyperconverged Infrastructure — Installs directly onto physical servers via an ISO installer, combining compute, storage and networking into one managed platform.
Kubernetes-Native Virtualization — Runs virtual machines as KubeVirt-managed workloads, allowing VMs and containers to run side by side on the same cluster.
Distributed Storage via Longhorn — Provides replicated block storage for VM disks across nodes without requiring a separate SAN or NAS appliance.
Rancher Integration — Provisions downstream Kubernetes clusters directly from VMs running inside Harvester for unified multi-cluster management.
No Kubernetes Expertise Required — A web-based management UI abstracts away Kubernetes internals so operators can manage VMs much like a traditional hypervisor.
VM Live Migration — Supports live migration of virtual machines between nodes for maintenance and load balancing without downtime.
Advanced Networking — Supports VLANs and multiple network interfaces for segmenting VM traffic in production data center environments.
Zero Licensing Cost — Fully open source with no per-CPU, per-socket or per-VM licensing fees, unlike commercial HCI platforms.
Pros & Cons
Pros
Completely free and open source with no licensing costs, unlike VMware vSphere or Nutanix
Built entirely from proven open-source components (Kubernetes, KubeVirt, Longhorn, KVM) rather than a proprietary hypervisor
No Kubernetes expertise required to operate despite being Kubernetes-native underneath
Native integration with Rancher for organizations already managing multiple Kubernetes clusters
Runs legacy VM workloads and modern containerized applications on the same infrastructure layer
Cons
Commercial support is only available through SUSE, so organizations without a support contract rely on community channels
Younger project than mature commercial HCI platforms, with a smaller third-party ecosystem and fewer integrations
Requires dedicated bare-metal hardware and careful network planning, which raises the operational learning curve versus a managed cloud service
Feature parity with VMware vSphere in areas like advanced DRS-style scheduling is still evolving
Best suited to teams already comfortable with Kubernetes-adjacent operations, which can be a barrier for traditional VMware administrators

Frequently Asked Questions
What is Harvester used for
Harvester is used as an open-source hyperconverged infrastructure platform for running virtual machines and containerized workloads on bare metal servers, often as a free alternative to VMware vSphere or Nutanix.
Is Harvester free to use
Yes, Harvester is completely free and open source with no licensing fees. Optional paid enterprise support is available from SUSE.
Who maintains Harvester
Harvester is maintained by SUSE's Rancher engineering team, the same team behind the Rancher Kubernetes management platform, following SUSE's 2020 acquisition of Rancher Labs.
Does Harvester require Kubernetes knowledge to use
No, Harvester provides a web-based management dashboard that abstracts away Kubernetes internals, so operators can manage VMs without prior Kubernetes experience.
What technologies is Harvester built on
Harvester is built on Kubernetes, KubeVirt for virtualization, Longhorn for distributed storage, and Linux with KVM as the underlying hypervisor technology.
Can Harvester replace VMware vSphere
Many organizations adopt Harvester as a free, open-source replacement for VMware vSphere or Nutanix, particularly to avoid rising licensing costs, though feature parity in some advanced areas is still evolving.
