  44 * MachineClass:
  45 * @get_hotplug_handler: this function is called during bus-less
  46 *    device hotplug. If defined it returns pointer to an instance
  47 *    of HotplugHandler object, which handles hotplug operation
  48 *    for a given @dev. It may return NULL if @dev doesn't require
  49 *    any actions to be performed by hotplug handler.
  50 * @cpu_index_to_socket_id:
  51 *    used to provide @cpu_index to socket number mapping, allowing
  52 *    a machine to group CPU threads belonging to the same socket/package
  53 *    Returns: socket number given cpu_index belongs to.
  54 * @hw_version:
  55 *    Value of QEMU_VERSION when the machine was added to QEMU.
  56 *    Set only by old machines because they need to keep
  57 *    compatibility on code that exposed QEMU_VERSION to guests in
  58 *    the past (and now use qemu_hw_version()).
