I don't totally agree with you: "qemu my_pc", when my_pc is a file, as you
explain, has an implicit behavior "use vm with 128 MB and hda my_pc and the
default network card", so perhaps we can have also "qemu my_pc", when my_pc is a
directory, has an implicit behavior "use vm as defined in my_pc/config and hd
found in this directory".

BUT, as there is a lot of debates on this, I AGREE WITH YOU: we should choose
the most simple, logic and common solution... and "-c" seems the good one.

Jorge made a very good work, it should be sad to not use it.

Laurent
