    AMD also gave a lot of help to initially port the Linux kernel to AMD64 processors (they kind of coordinated the whole thing via www.x86-64.org), and they continue to be an important contributor to the Linux kernel (I see many patches related to chipset drivers, SATA, etc). The also contribute to OpenSolaris, OpenJDK, KVM (NPT support, Vista / XP 64-bit bugfixes, etc). AFAIK most of these open source contributions are made by AMD employees from the OSRC (Operating System Research Center) group.

  2. Re:Does XEN have a future? by David+Jao · · Score: 2, Informative · on Running Xen

    There are a few things that Xen supports that KVM doesn't, such as live migration.

    Wait, what? KVM supports live migration, and in fact KVM supports it better than Xen ever did.

    Xen allows live migration only between machines with identical or very similar processors. KVM supports live migration between any two systems that can run KVM. For example, if you want to live migrate from an Intel to an AMD host, KVM is your only option. If you want to live migrate a 32-bit guest between a 32-bit host and a 64-bit host, KVM will do that, Xen won't.

  3. kvm should be looked into if you are considering by bl8n8r · · Score: 3, Interesting · on Red Hat Releases RHEL 5.1, Includes Virtualization

    I've had 4 windows 2000 servers running under kvm[0] (on centos 5.0 host). The performance seemed about the same as vmware, albeit I wasn't able to get dnsmasq and VDE[1] running correctly. Anyway, kvm is rolled into the centos 5 kernel and it does GUI where Xen does not. It's a bit ragged to setup, but looks promising.

  4. OS X side-by-side with Linux using KVM by kinema · · Score: 1 · on Run Mac OS X Apps On Linux?

    - QEMU is a fast and open source emulator that can be used to emulate, among others, x86 PCs, AMD64 PCs, and Power Macs. This should allow you to run OS X as a guest OS. If you use QEMU to emulate an x86 on an x86, or an x86 or AMD64 on AMD64, it should run close to native speed. That is, as far as the CPU is concerned. Other hardware, graphics hardware in particular, will not have native performance.
    An even better option here would be to use KVM (which in turn uses QEMU) on Linux to run OS X in a virtual machine. There are questions about the legality of this approach because if I remember correctly OS X's license specifically forbids running it in a virtualized environment. Also I believe that QEMU is missing some features required to host OS X.
  5. Re:Why? by QuantumG · · Score: 3, Informative · on Linux Gains Two New Virtualization Solutions

    Which is why I mentioned file systems...

    That said, you mentioned KVM.. KVM (for Kernel-based Virtual Machine) is a full virtualization solution for Linux on x86 hardware containing virtualization extensions (Intel VT or AMD-V). (from here). It *is* a hardware driver.

    KVM ? Though it is in early stages of development, in theory, it may be able to run faster than Xen. It's goals, however are different from that of Xen's
