    The problem is not with Xen, but the virt-manager itselft. even if you use Qemu or KVM.
    Run virt-manager as root.

    screenshot is very small, cant see clearly. are you running as root already?

    Oh, sorry I didnt read the error correctly in first post.
    You are running in Paravirtual mode.

    The installation media path is for repository tree of the same linux disto.
    When you have to install another operating system using ISO, you need to run in Full Virtualization.
    So you can get this menu.



    EDIT:
    When you select media url. the example is given under text box.

    Exclamation

    Thanks b2bwild. Now i provided CentOS as installation source
    It creates initrd image and allows storage and but then it throws following error message

    (xend.err 'Error creating domain: I need 262144 KiB, but dom0_min_mem is 262144 and shrinking to 262144 KiB would leave only 235124 KiB free.')
    I'm having 512MB RAM.

    Then i changed /etc/xen/xend-config.sxp file and increased
    dom0-min-mem 256
    to
    dom0-min-mem 512
    and reboot machine with SElinux disabled...still getting the error about dom0_min_mem.

    I'm using Fedora 7 KDE environment.

    Any thoughts on this?

    Nice you made it.
    give a try to xenner.
    It will allow you to use xen, without booting xen kernel.
