    From what I've been reading Xen is a standalone product that has it's own Linux Kernel.

    Why is there no install without an existing OS?
    (If there is, a link would be nice.)

    All installs of Xen require Grub, which means you are dual booting.

    XenServer is the only standalone install I have found, but it requires two computers, one Windows with .net 2.0.

    If you search Youtube or Google for "install xen" you get, Install Xen on CentOS, Install on Ubuntu or Install on OpenSUSE.

    Reading the documentation it states that Xen has it's own Kernel and does not need an OS. Is there an install method for Xen 3.3 where an OS is not present on a system?

    XenServer is the only one I have found that installs alone.

    It is somewhat confusing if there is a Linux client to administer the VM's.

    Some say yes some say no.

    Best damn Server Virtualization Book, Period

    Is this true? Is it possible to not need Windows to administer to XenServer?

    Use of GRUB does not mean you're dualbooting, it means you're using GRUB.
    Xen installs its own kernel, so you can later delete grub entries for other kernels or even remove other kernels and you got yourself a hypervisor.

    Install opensuse, install xen, edit grub menu, delete other kernels, reboot, job done.

    The Xen you are talking about is not a true hypervisor, and is not a bare metal install.
    I have the hardware support to use XenServer as a true hypervisor, no KVM.
    And so will not have to use any modified linux kernels, am not limited to Linux only.
    I will be able to run Windows as guest, where in your setup you can't run Windows as guest.

    Since you are the local Linux Bhadisatva, I was hoping for confirmation on the Linux admin Client.

    Thanks for your input.

    I was under the impression that most distros allow you to run Linux as Dom0 under native-Xen.

    From there you can manage guest virtual machines, which will run ALONGSIDE your host domain rather than within.

    I'm more of a Bratislava than Bhadisatva ... but ...
    There are many solutions to get Windows running. Did you try the free ESXi?
