Xen

  1. As time goes on more OSes are getting Dom0 support, so there's a growing need to provide a platform independent set of tools from which to operate Xen. This talk will expose the different mechanisms used on NetBSD that diverge from the Linux approach, and how Xen is improving its userspace tools to provide a more platform independent support.

    The talk also touches upon various features that BSD provides or plans to provide with Xen, thus presenting a coherent roadmap view of where we've come from, and what lies ahead.

    What's in this talk:
    - Xen and BSD
    - Status updates from the world of BSD
    - Ecosystem/userbase

  4. This talk with discuss the design and implementation of a new type of hypervisor derived from the Xen code base. µ-Xen has been built and optimized for modern CPUs and chipsets, and thus assumes the presence of CPU and IO MMUs that are virtualization capable. µ-Xen borrows extensively from the production-proven and tuned Xen code base, but removal of support for older hardware and PV-MMU guests has enabled significant simplification of the code. µ-Xen supports optimizations in support of running large numbers of very similar virtual machines, through the support of a native 'vmfork' optimization and efficient re-merging of shareable pages.

    The primary goal of µ-Xen has been to run as a late-load hypervisor on an existing OS. It has a narrow and well-defined interface to the services it expects from the underlying OS, which makes it easy to port to other OSes, or to enable it to run on bare metal. During initialisation, µ-Xen can de-privilege the running host OS into a VM container, enabling it to establish itself as the most privileged software component in the system. Thus, µ-Xen enforces the privacy and integrity of itself and VMs that it is running, against a faulty or malicious host OS, while co-operating with the host OS on the actual allocation of physical resources.

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.
