Proxmox VE

Open-source hypervisor combining KVM and LXC virtualisation

Visit Proxmox VE

Overview

What Proxmox VE does

Proxmox VE is a complete open-source platform for enterprise virtualisation that runs on Linux-based x86 hardware. It combines two virtualisation technologies: KVM (Kernel-based Virtual Machine) for running Windows and Linux guests as full virtual machines, and LXC (Linux Containers) for lightweight Linux container deployments. Both technologies share the same management interface, allowing operators to choose the most efficient approach per workload. Storage is managed through software-defined capabilities including ZFS and Ceph for redundancy and clustered deployments. The platform targets cost-conscious IT environments seeking to replace expensive commercial hypervisors like VMware vSphere. A high-availability clustering architecture enables automatic failover between nodes, whilst backup and disaster recovery features support both VMs and containers. The web-based management UI provides infrastructure visibility and administration without requiring proprietary tools. Proxmox also offers Proxmox Backup Server and Proxmox Mail Gateway as complementary products, with centralised management available through Proxmox Datacenter Manager. Deployed by organisations ranging from small hosting providers to large enterprises, Proxmox scales from single-node installations to multi-site clustered deployments. The project provides commercial support through tiered subscription models, though community editions can access the platform through forums and community resources.

What people use it for

  • Open-source datacenter virtualisation for hosting providers and cloud platforms
  • Cost-sensitive enterprise virtualisation replacing commercial hypervisors
  • High-availability clustering for disaster recovery and business continuity
  • Container deployments using LXC as lighter-weight alternative to Docker
  • Hybrid VM and container workloads in a single management interface
  • Backup and archival infrastructure alongside primary virtualisation

The honest half

Where it falls short

Concrete and checkable, so you can decide whether any of them matter to you. This is the half of a review a vendor will not write about Proxmox VE.

  • Per-socket licensing model: cost scales with CPU socket count, not vCore count, resulting in high costs for multi-socket servers
  • Linux-based host only; Windows hypervisors not supported, limiting adoption in Windows-focused organisations
  • Clustering and high-availability setup requires operational expertise and careful network configuration
  • Commercial support tiers limit advanced features (just-in-time access, network flow logs) to paid subscriptions
  • Smaller ecosystem of third-party plugins and integrations compared to VMware vSphere
