[Ovirt-devel] [PATCH]: Allow the WUI to manage the hardware it is running on

    In the rc.local, attempt to contact the host we are running
    on.  If we succeed, great, we can manage it with the rest of the nodes.  If
    we fail, no big deal, it just won't be available.  Note that we can't do
    this in the ovirt-wui-dev initscript because it happens too early in boot
    (we need at least host-browser up for this to have a chance of working).
