What it is

Open-source server virtualization that runs KVM virtual machines and LXC containers side by side. Clustering, software-defined storage and networking, high availability and backup are all there, each driven from its web UI.

Problems it closes

  • You want enterprise virtualization without per-core licensing.
  • Virtual machines and containers both need to run on the same host.
  • An HA cluster has to go up on commodity hardware.

How administrators run it

  • Install on Debian/bare-metal and run KVM VMs and LXC containers from the web UI.
  • Cluster nodes together for high availability and live migration.
  • Back up guests with the built-in tools or Proxmox Backup Server.

Strengths & trade-offs

Strengths

  • Free and open source.
  • KVM VMs and LXC containers on one platform.
  • Clustering, HA, software-defined storage/networking and backup all included.

Trade-offs

  • Running and supporting it is on you unless you buy a subscription.
  • The stable enterprise repository needs a subscription.

Common questions

Is it really free?

Yes. A paid subscription adds the enterprise update repository and vendor support, but the platform itself costs nothing.

VMs, or containers?

Both — full KVM virtual machines and lightweight LXC containers.
