    virtio - Fix virtio block device cylinder count reporting
    
    * qemu's virtio caps its reported cylinder count to 16383, which
      confuses fdisk.
    
    * Check for the legacy cap and recalculate the reported cylinders
      based on the other parameters, and report this on the console.
    
    * We decided not to modify fdisk for now.  Instead we "fixed" virtio.
