Oh, that's true ... I did not notice it 'cause there was no error message when I tried to start the "none" machine with "-kernel". But looking at the code in hw/core/null-machine.c, it really seems that there is nothing in here :-( So never mind, please forget about this patch. (but now I wonder whether the "none" machine could be improved to provide the features of the "dummy" machine, too?) Thomas

The "none" machine is defined to be be filled with QMP commands, perhaps the generic-loader object can replace the "-kernel" parameters? Laurent

As far as I can see, there is even more to be done here: The "none" machine apparently does not instantiate any CPUs yet, so we would need to add the possibility to add a CPU to the empty here, too...

You can get an empty machine with "-M none" nowadays, so the m68k dummy board (introduced in 2007) seems to be pretty redundant since the "none" machine has been added in 2012.
