The document discusses the goals and roadmap of the Xen Project, an open source hypervisor. The Xen Project aims to build the industry standard hypervisor, maintain high performance, and support multiple CPU types from servers to clients to mobile phones. Virtualization provides benefits like server consolidation and increased manageability. Hardware advances like VT-x/AMD-V further reduce overhead allowing near-zero overhead virtualization. The roadmap includes improvements to security, scalability, client/mobile support, and research into areas like VM streaming and hardware fault tolerance.
