1. As part of the Google Summer of Code, we tried to add support for SeaBIOS in order to allow guest OSes to be booted directly from PV disk devices rather than from the emulated disk device. SeaBIOS is the BIOS implementation that upstream qemu uses. When the virtual machine is created, SeaBIOS upon initialization uses a generic Xenstore client to communicate with the back end and initialize the front-end block device that will connect to the back end. After the connection is established I/O requests are made via the BIOS int 0x13 interface, guest OSes use the int 0x13 without needing to be aware that PV drivers were used.

    Daniel Castro, PhD Student, Pohang University of Science and Technology

    Daniel is a PhD student at Pohang University of Science and Technology. He got involved with the Xen community through Google Summer of Code developing PV Drivers for Seabios. In 2007 he was introduced to the virtualization and web acceleration world. During that time he started to create data center consolidation solutions, that is when he got involved with the Xen Hypervisor. During that time his PhD aspirations were born. Daniel also worked closely with Citrix Netscaler, and started contributing to netscalerkb.com and later became an administrator. Simultaneously he was teaching first level Programing at his former University. Daniel is very dynamic and creative with a keen drive for learning diverse subjects from politics comics, he currently enjoys Motorcycles and Strategic War Games. He dreams one day to travel around the world in a motorcycle with his wife.

  2. This talk explores what has gone in so far in the Linux kernel (version 3.0 and 3.1) and which Linux distributions are deliverinbg Xen again. The talk explores outstanding challenges and the pieces that are missing and what we can do, and what we cannot do working with Linux.
    Ian Campbell, Principal Software Engineer working on Xen and Linux kernel, Citrix

    Ian Campbell has been involved with the Xen project since joining XenSource in 2005. Today he is a Principal Software Engineer at Citrix Systems, Inc working on Xen where his interests include Linux on Xen, paravirtualised networking and toolstack issues. Prior to Citrix (and XenSource) he worked on embedded Linux systems at Arcom Control Systems.

  3. The Xen has a tracing infrastructure that can collect a large amount of very detailed data about what's happening at the hypervisor layer. But making sense out of that data isn't an easy thing to do. In this talk I give an overview of xenalyze, a powerful tool I've developed for finding meaning in the vast amounts of data generated by xentrace, enabling both debugging and performance analysis.

    George Dunlap received his PhD in Computer Science and Engineering from the University of Michigan in 2006. He started doing work in the Xen hypervisor as part of his PhD research in 2004, and has continued to this day. He specializes in performance analysis and optimization, and is currently writing a next generation scheduler for Xen.

  4. We implement link virtualization based on Xen. Link virtualization is a basic building block for network virtualizaiton that allows the co-existence of different Internet protocols. To minimize virtualize overhead, we use SR-IOV with Intel 82576

    Presenter: Shin Hyoung Lee, Ph.D student, Korea University

    Shin Hyoung Lee is a Ph.D student at Korea University. He received an M.S. degree in computer science from Korea University. His research topic is virtual router based on Xen. His virtual router makes virtual network for Future Internet

  5. The talk will cover SR-IOV scalability and challenges in Xen, as well as NUMA I/O support in Xen.

    Presenter: Kevin Tian, Intel

    Kevin Tian currently works in Intel Open Source Technology Center. He joined Intel in 2003 after getting communication-system Master Degree from University of Electronic and Scientific Technology of China. He is then involved in several virtualization projects since 2004, with technical contributions in various Xen areas: IA64/VT-i, x86/VT-x, power management, client virtualization, performance, etc. Now Kevin is studying I/O scalability with Xen.

Xen is an open-source type-1 or baremetal hypervisor, which makes it possible to run many instances of an operating system or indeed different operating systems in parallel on a single machine (or host). Xen is the only type-1 hypervisor that is available as open source. Xen is used as the basis for a number of different commercial and open source applications, such as: server virtualization, Infrastructure as a Service (IaaS), desktop virtualization, security applications, embedded and hardware appliances. Xen is powering the largest clouds in production today.
