Yes, it just a plain text in the GUI, that's on purpose to off-load our
responsibilitie to testing all the fields if we list them individually in
the GUI, which means we'll tested out all the combinations.  By saying that,
I still advise Liping while on the task, don't just plainly passing in the
text that user specified.  If you look at poky-qemu-internal, you'll see
there're certain things setting there for different architectures, so I'd
expect to some level of checking to ensure there's no conflict between what
user passing in and what already setted in the script or at least generate
some warning...
