    Xen Support in the Linux Kernel: Upstreaming Efforts and New

    Stefano Stabellini,
    Senior Software Engineer, Citrix R&D 

    Xen (http://www.xen.org/) reuses many externals of open source
    projects, Qemu (http://qemu.org/) and Linux in particular.  During
    the first years of existence, Xen accumulated a large number of changes
    to these external projects, but then struggled to upstream them.

    In the last couple of years, the Xen community has been trying to
    remove the dependencies on downstream modifications, and establish
    better relationships with other open source communities.  What is the
    current status of Xen in relation with other free software projects?

    At the same time, Xen development proceeded at a fast pace, and several
    new features were introduced; this talk will go through one in
    particular: PV on HVM support in the Linux kernel.  Traditionally,
    Linux has always run on Xen either as a pure PV guest or as a
    virtualization-unaware guest in an HVM domain.  Under the name "PV on
    HVM", work has been done to make Linux aware that is running on Xen,
    and enable as many PV interfaces as possible, even when running in an
    HVM container. 

    Stefano Stabellini (http://www.stabellini.net/) is a Senior
    Software Engineer at Citrix R&D (formerly XenSource, Ltd.), working
    on the open source Xen Platform
    team.  He has been working on Xen since 2007, focusing on several
    different projects, spanning from Qemu to the Linux kernel.  He
    currently maintains libxenlight
    Xen support in Qemu, and PV on HVM
    (http://wiki.xensource.com/xenwiki/XenLinuxPVonHVMdrivers) in the
    Linux kernel.  Before joining Citrix, he was a researcher at the
    Institute for Human and Machine Cognition (http://www.ihmc.us/),
    working on mobile ad hoc networks.
