In March, 2011, we released the Xen Cloud Platform (XCP) version 1.0, a fully-featured server virtualization platform based on the Xen hypervisor. XCP ad s additional functionality on top of Xen, such as a management server for ease of use and configurability, storage and network management, and easy integration with cloud orchestration layers like OpenStack and CloudStack. Today, Xen and XCP power the largest clouds in production.

In this talk we'll explore: - Xapi, the XenAPI management daemon, written in OCaml; - Cool functionality, such as live VM migration between hosts (with no shared storage); - PCI device passthrough to VMs for native performance; - A new system architecture designed to provide XCP with better security, scalability, performance, and reliability; - Future directions and next year's roadmap.
