    soft-qemu handling with F20 could image

    When the qume used with Linux image without
    a para-virtualized timer, various timing issues can happen,
    if the qemu process preempted in the wrong time, for example
    at timer test.

    The issues less like happens on low load, high core number
    host system, but it can happen.

    For soft qemu (TCG) generally recommended to explicitly disable the
    timer check.

    Pre-caching the Fedora `gate edition` image, which contains the
    the no_timers_check option.
