I think we agree at last.  Neither I nor my employer are interested in 
running qemu as a desktop-on-desktop tool, therefore I don't invest any 
effort in that direction, or require it from volunteers.

If you think a good GUI is so badly needed, either write one yourself, 
or convince someone else to do it.

(btw, why are you interested in desktop-on-desktop?  one use case is 
developers, which don't really need fancy GUIs; a second is people who 
test out distributions, but that doesn't seem to be a huge population; 
and a third is people running Windows for some application that doesn't 
run on Linux - hopefully a small catergory as well.  Seems to be quite a 
small target audience, compared to, say, video editing)

Do not meddle in the internals of kernels, for they are subtle and quick to panic.
