Proxmox

Proxmox is a powerful, open-source virtualization platform that unifies KVM virtual machines, LXC containers, and software-defined storage on a single Debian-based system.

Proxmox Virtual Environment (VE) delivers a bare-metal hypervisor that handles enterprise-grade virtualization without the licensing premium. By combining kernel-based virtual machines (KVM) and lightweight Linux containers (LXC) on a Debian foundation, it lets operators spin up diverse workloads side-by-side. Out-of-the-box support for Ceph storage, ZFS file systems, and software-defined networking means you can scale from a single home-lab node to a highly available, multi-datacenter cluster using a clean, built-in web console.
