Xen cloud platform
This document provides an overview of the Xen Cloud Platform (XCP) and its history and features. XCP is an open source virtualization platform based on the Xen hypervisor. It includes the Xen hypervisor, the Xen Cloud Platform distribution of XenServer from Citrix, and the XAPI management interface. XAPI acts as the backbone of XCP management and provides an API for orchestration with other cloud platforms. The document discusses XCP's features like live VM migration and storage, management options through XAPI and graphical tools, integration with cloud orchestration stacks, and new developments including improved support for Linux distributions and live storage migration capabilities.
