There are several HAL types available in winXP: these
are Uniprocessor

I haven't debugged further yet, -- because it were
not easy to find out what was causing the regression

it is the right HAL for qemu-kvm guest anyway.
It's not, but the regression indicates we

So this certainly was not related to adding the memory...

Each time I build qemu-kvm, my build script complains
that it is needlessly linked against libglib-2.0 without
using any symbols from that library. So is glib really
