Xen 2.0 Virtual Machine Monitor Released

Posted by michael on from the xen-and-the-art-of-system-maintenance dept.

An anonymous reader writes "The Xen team are pleased to announce the release of Xen 2.0, the open-source Virtual Machine Monitor. Xen enables you to run multiple operating systems images concurrently on the same hardware, securely partitioning the resources of the machine between them. Xen uses a technique called 'para-virtualization' to achieve very low performance overhead -- typically just a few percent relative to native. This new release provides kernel support for Linux 2.4.27/2.6.9 and NetBSD, with FreeBSD and Plan9 to follow in the next few weeks. Xen 2.0 runs on almost the entire set of modern x86 hardware supported by Linux, and is easy to 'drop-in' to an existing Linux installation. The new release has a lot more flexibility in how guest OS virtual I/O devices are configured. For example, you can configure arbitrary firewalling, bridging and routing of guest virtual network interfaces, and use copy-on-write LVM volumes or loopback files for storing guest OS disk images. Another new feature is 'live migration', which allows running OS images to be moved between nodes in a cluster without having to stop them. Visit the Xen homepage for downloads and documentation."

    I'm using UML right now, is this comparable/interchangable, and what would be the benefits?

    And you forgot to apply the frosting to your well-crafted pist. Now we may never know the joys of frosting pists for the remainder of this century due to your irresponbility of maintaining frostiness within predetermined specifications.

    The following graph indicates the proper curve of applying frost to your pist:

  5. Wine? by Anonymous Coward · · Score: -1, Offtopic

    Whats wrong with wine? I know it isn't perfect, but most apps run just fine under wine. I'm sure CodeWeavers would love to fix whatever part is missing that makes your app not work, for some $$$. (Depends on the problem of course, there are a lot of things wrong that would only take a month to fix, so some money will often help them choose which to do)

    That would be great running Linux with a built in secure firewall OpenBSD based of course.

    This isn't redundant. It's the only post in the entire thread that asks a very important question.

      Not to mention the answer got modded up to +5. I can see the answer being of more value than the question, but to mod it down 2 points to zero is a bit odd. Have you meta-moderated lately?
