  • 10. Xen Today ® ~20% enterprise server market share >80% of the Public Cloud is Xen based World's largest virtualization deployments are Xen based Development Community: over 50 Companies, 25 Universities, from 25 Countries, ~250 developers More than 20,000 code submissions Used in Severs, Desktops, Laptops, Storage Appliances, Network Appliances and Smart Phones x86, IA64, ARM support
  • 11. ® Xen Powers the World’s Infrastructure Clouds “ Xen is great. It’s powerful and easy to use. But most important is the very active community around it. That was a very big reason for us in selecting Xen. Werner Vogels CTO, Amazon.com ”
  • 12. Xen Tops Performance Comparisons ® “Xen is the Porsche of hypervisors” Keith Ward, Virtualization Review “Xen outperforms VMware ESX 3.5 by 41% in user scalability tests.” The Tolly Group
  • 13. ® Pioneers of OS Para-virtualization Xen Hypervisor First and Best to support new CPU, chipset, and Smart IO Technologies
  • 14. ® ® Xen 4.0
  • 15. Xen 4.0 ® Released 12 Apr 2010 Reliability, Availability, Scalability Enhanced MCA support, blktap2, netchannel2 Memory optimizations pvops privileged domain support Fault tolerance for VMs
  • 16. Hardware Fault Tolerance ® Restart-HA monitors hosts X and VMs to keep apps running Hardware Fault Tolerance X with deterministic replay or checkpointing Xen’s Software-Implemented Hardware Fault Tolerance enables true High Availability for unmodified applications and operating systems
  • 17. Hardware Fault Tolerance ® University of British Columbia’s “Remus” project is now in xen 4.0 Smart checkpointing approach yields excellent performance VM executes in parallel with checkpoint transmission, with all externally visible state changes suppressed until checkpoint receipt acknowledged Checkpoints delta compressed Checkpointing possible across wide-area, even for multi- vCPU guests
  • 18. SR-IOV ® SR-IOV: Single Root IO Virtualization Virtualization friendly IO devices High performance, high efficiency, low latency Enables even the most demanding applications to now be virtualized Compatible with live relocation via hotplug World First, demonstrated at Intel Developer Forum in September!
  • 19. SR-IOV NIC Demonstration ® Dell 10G Switch Dell R710 Server Dell R710 Server XenServer and Intel 10G SR-IOV NIC XenServer and Intel 10G SR-IOV NIC NFS Common Storage w/OpenFiler Dell R710 Server XenServer and Intel 10G SR-IOV NIC Full 20Gb/s bi-directional throughput to VMs Low latency, High CPU efficiency Live relocation between hosts - Even hosts with different NICs
  • 20. Network Performance ® 201% Type-0 123% 103% 100% s/w only basic smart SR-IOV native NIC NIC • New Smart NICs reduce CPU overhead substantially • Care must be taken with SR-IOV NICs to ensure benefits of VM portability and live relocation are not lost • Need for an industry standard for “driver plugins”
  • 21. ® ® Xen Cloud Platform
  • 22. Xen Cloud Platform (XCP) ® XCP Expands Xen.org’s scope beyond the core hypervisor, to create a full virtual infrastructure layer for Cloud deployments Simplify and streamline use of Xen by Cloud providers and vendors Promote greater standardisation of components between vendors Advanced virtual infrastructure to enable Virtual Private Datacenters rather than just Virtual Private Servers Multi-tenant hosts, networking, storage, etc Promote interoperability between xen-based clouds and other clouds Drive standards activities via DMTF

  • 30. ® ® Xen Client Initiative
  • 31. The Xen Client Initiative ® Formed in 2007 to develop Xen for desktop and laptop Develop enhanced power management, USB, WiFi, WWAN, 3D Graphics, fingerprint reader, multi-touch, etc Support for latest hardware technologies Tiny footprint hypervisor, Embeddable in Flash memory or small disk partition Aiming to make virtualization ubiquitous on client devices...
  • 32. Client Hypervisor Benefits ® Security, Manageability, Supportability, Auditability Building Multi-Level Secure systems Run multiple VMs with policy controlled information flow ● E.g. Personal VM; Corporate VM; VM for web browsing; VM for banking Trusted hypervisor provides secure isolation Enables “out-of-band” management and policy enforcement via Service VMs Malware detection, remote access, image update, backup, VPN, etc. ð Requires a true type-1 hypervisor architecture ð Xen is ideally suited to this!
