Harvester — Virtual Machines and Containers in One Cluster What it is Harvester is an open-source hyperconverged platform.

Instead of running a VM farm next to a Kubernetes cluster, both workloads run on the same nodes with one control plane. For administrators this reduces duplicated infrastructure and makes mixed setups easier to run.

Harvester — Virtual Machines and Containers in One Cluster

What it is

Harvester is an open-source hyperconverged platform. It brings together two pieces that usually live apart: Kubernetes for containers and KVM for virtual machines. Instead of running a VM farm next to a Kubernetes cluster, both workloads run on the same nodes with one control plane. For administrators this reduces duplicated infrastructure and makes mixed setups easier to run.

How it works

The system uses KubeVirt to expose KVM inside Kubernetes. Storage comes from Longhorn, a distributed block layer. Networking relies on standard CNI plugins with VLAN or overlay options. From the outside it behaves like any other Kubernetes cluster. The difference is that you can create VMs with the same tools you use for pods. Management happens through a built-in dashboard, Rancher, or simply kubectl. Nodes can be added gradually and the whole thing runs on ordinary x86 servers with virtualization support.

Technical profile

Area Details
Base platform Kubernetes + KubeVirt + Longhorn
Hypervisor KVM
Storage Longhorn (replicated block volumes)
Networking CNI plugins, VLANs, overlays
Management Web UI, Rancher integration, kubectl
Hardware x86_64 with VT-x/AMD-V
License Apache 2.0

Installation guide

1. Prepare servers with virtualization extensions enabled.
2. Boot the Harvester ISO on the first machine.
3. Assign IP addresses, storage disks, and select the role (management or worker).
4. Add more nodes by repeating the process.
5. Log into the web UI to check cluster health.
6. Optionally hook it into Rancher for multi-cluster management.

Usage scenarios

– Replacing small VMware or Proxmox clusters with a Kubernetes-native stack.
– Edge locations where both VM and container workloads must run on the same hardware.
– Development labs where teams need to test pods and VMs side by side.
– Hybrid rollouts where legacy services stay in VMs while new ones run as containers.

Limitations

– Still younger than vSphere or OpenStack, so some enterprise features are missing.
– Hardware compatibility depends on Linux and KVM drivers — testing is required.
– The mindset is Kubernetes-first, which can be challenging for teams used to classic hypervisors.

vSphere Hypervisor

vSphere Hypervisor (ESXi) — VMware’s bare-metal layer What it is ESXi, officially called vSphere Hypervisor, is VMware’s bare-metal hypervisor. You install it straight on the server, no Linux or Windows host underneath. For many datacenters it’s the base layer: stable, predictable, and designed to integrate with the rest of VMware’s stack (vCenter, vMotion, HA, DRS). Free to download, but the good stuff (central management, clustering, API writes) comes only with licenses.

oVirt

oVirt — upstream virtualization for Red Hat shops What it is oVirt is the community project behind Red Hat Virtualization (RHV). At the core it’s just KVM + libvirt, but with a full management layer wrapped around it. Think of it as “vCenter, but open source and Red Hat flavored.” It’s heavier than Proxmox, but it has been running in production datacenters for years where admins wanted VMware-like features without VMware licensing.

Xen Project

Xen Project — bare-metal hypervisor that refuses to die What it is Xen Project is a type-1 hypervisor that’s been in use for more than 20 years. It started as an academic experiment in Cambridge, later became the base for many VPS platforms, and even powered AWS EC2 for years. Today it’s still maintained under the Linux Foundation. Not as trendy as KVM, but still useful if you need a small, security-focused hypervisor or want to separate workloads at the hardware level.

Windows Sandbox

Windows Sandbox — disposable Windows environment for safe testing What it is Windows Sandbox is a feature built into modern Windows (Pro and Enterprise editions, from Windows 10 1903 onward). It provides a temporary, isolated environment that runs a clean Windows instance on demand. The main idea is simple: you launch Sandbox, test or run something risky, then close it — and everything inside is discarded. No need to spin up a full VM manually or reinstall the OS after running untrusted software

Virtuozzo

Virtuozzo — mix of containers and VMs with hosting DNA What it is Virtuozzo has its roots in OpenVZ, the old Linux container project. Over time it turned into a commercial platform used by hosting providers to sell VPS long before Docker became a buzzword. Today it combines two approaches: lightweight containers for density and KVM-based virtual machines when you need a full kernel. That mix is what made it popular in the service-provider world.

VirtualBox

VirtualBox — cross-platform workhorse for labs and odd jobs What it is (short) VirtualBox is a type-2 hypervisor maintained by Oracle. It runs on Windows, Linux, macOS, and Solaris, and it spins up guest systems with minimal ceremony. Not the fastest thing on earth, and that’s fine; it’s the “it works everywhere” option that sticks around in classrooms, dev laptops, and compatibility test rigs.
