1. As mentioned by @Justin Breitfeller, @Vidar Wahlberg solution is a hack which might not work in future version of Android.
2. @Vidar Wahlberg perfer a hack because other solution might "cause the map to be recreated and redrawn, which isn't always desirable". Map redraw could be prevented by maintaining the old map fragment, rather than creating a new instance every time.
3. @Matt solution doesn't work for me (IllegalStateException)
4. As quoted by @Justin Breitfeller, "You cannot inflate a layout into a fragment when that layout includes a . Nested fragments are only supported when added to a fragment dynamically."

My solution:

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,                              Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.fragment_map_list, container, false);

    // init
    //mapFragment = (SupportMapFragment)getChildFragmentManager().findFragmentById(R.id.map);
    // don't recreate fragment everytime ensure last map location/state are maintain
    if (mapFragment == null) {
        mapFragment = SupportMapFragment.newInstance();
        mapFragment.getMapAsync(this);
    }
    FragmentTransaction transaction = getChildFragmentManager().beginTransaction();
    // R.id.map is a layout
    transaction.replace(R.id.map, mapFragment).commit();

    return view;
}
