    Overview

    It is difficult to find a good (unbiased) review of virtualization options and I will do my best to give my impressions of each option.

    I do not mean to come across as a big fan of Wikipedia, but in trying to provide an introduction and attempt to provide a more neutral overview it seems a good place to start.

    Non-wikipedia: Here is a nice overview

    And of course Wikipedia :
    http://en.wikipedia.org/wiki/Compari...rtual_machines

    Reminder: The Ubuntu wiki is community maintained. If you see a page that needs clarification or updating please consider contributing to the wiki.

    Open source options
    • QEMU / KVM.
    • OpenVZ.
    • VirtualBox (OSE).
    • Xen.


    Closed source options
    • Citrix XenServer.
    • Parallels (comercial version of OpenVZ).
    • VirtualBox (PUEL).
    • VMWare (Player and Server).


    Performance : Fastest to slowest

    This is my personal subjective list and I offer it as, without any benchmarks or pretense of non-bias (I have no personal experience with Xen):

    OpenVZ > KVM > VirtualBox = VMware Server 1.0.x > VMWare Server 2.0 > Qemu + Kqemu > Qemu

    Comments: OpenVZ is supported in Ubuntu 8.04 (Gutsy) but is not yet in the Intrepid repos.


    Xen

    Gui front ends : Yes.
    Comments: It appears Xen will no longer be maintained server side (Dom0 / Host) in Ubuntu. Client side (DomU / Guest) is supported. See the "how-to" post for a link to how-to-forge (which by report works on 8.10).


    VirtualBox

    Comments: OSE has some limitations. See VirtualBox Editions

    Comments : I know it is closed source, but IMO VMWare server offers some nice features (64 bit guests, bridging to wireless cards, easier networking).

    There are two mistakes one can make along the road to truth...not going all the way, and not starting.
