Hi Criping,

Thanks for the patch. Overall I think this looks good.

However, one thing I feel the need to run by Richard, as he expressed 
some preferences with how the poky-qemu script would work with regard to 
options.

Richard: Criping's patch would remove the standalone options we had to 
the poky-qemu script (e.g, nographic, serial) and instead requires the 
user to specify them in one command option which can take any qemu 
command switch.

So for example:

poky-qemu qemux86 nographic

would become:

poky-qemu qemux86 "<-nographic>"

The benefit of this is that this allows the user to specify any qemu 
option they wish. Previously they were limited by the options we allowed 
them to specify (which were quite limited).

I tend to feel that this approach is more flexible, and scales better 
than having to support each and every qemu option with our own script 
syntax. Is this acceptable, or should we continue to support our own 
custom options in addition to Criping's new approach?
