XCP-ng

XCP-ng is an open-source virtualization platform based on the Xen hypervisor and on the XenServer code. It is developed as a community project and backed by Vates SAS, a French open-source software company based in Grenoble. Vates was registered in 2012 and also builds Xen Orchestra, the web interface and backup platform for XCP-ng. Together they are sold as Vates VMS with professional support.

Features

• Xen-based hypervisor for Windows and Linux virtual machines on bare metal
• Xen Orchestra as web interface for hosts, pools, live migration, snapshots and backup
• Tools for migrating virtual machines from VMware (ESXi) to XCP-ng, described as a few clicks in Xen Orchestra
• Upgrade path from XenServer, regular long-term-support releases
• Pro support and the Vates VMS stack for companies that want a vendor contract

Strengths and limits

XCP-ng fits teams that know the Xen world or want a classic hypervisor with pools and shared storage, and it has a clear commercial support path from a European vendor. The project is smaller than Proxmox VE and has no container platform built in, so Linux containers need a separate setup. Some Xen Orchestra functions are reserved for the paid edition.
