XCP-ng

XCP-ng is a turnkey virtualization platform built on the Xen hypervisor and the XenServer codebase, installed on bare metal as a ready-to-run appliance. Unlike the commercial products it descends from, every feature is open and free with no paywalls or license tiers, making it a self-hosted alternative to proprietary virtualization.

VMs can be run, snapshotted, live-migrated, and grown, and the platform handles container workloads too. Hosts are managed locally and remotely over CLI, GUI, and the XAPI management API, with Xen Orchestra serving as the de facto web administration and backup tool.

XCP-ng is developed collaboratively as part of the Vates VMS stack and ships as a bootable ISO. GPL-2.0 licensed, with a forum, documentation, and issue tracking for support.
