I am interested in fixing this. So what's the technical challenge here? When you say "support for single-stepping and breakpoints in the emulator is quite minimal", do you mean it's a problem in the Qemu side, rather than something wrong in the kvm kernel modules? If so, and if we want to fix this, we need to make some changes in the Qemu code, right?
