That was not what i suggested tho. tools/kvm/ would work plenty fine.

But my point was over-modularization, which due to the KVM/qemu split we all suffer from. Modularizing along the wrong interface is worse than not modularizing something that could be. So when designing software you generally want to err on the side of _under_-modularizing. It's always very easy to split stuff up, when there's a really strong technical argument for it. It's very hard to pull the broken pieces back together though once they are in difference domains of maintanence - as then it's usually social integration that has to happen, which is always harder than a technical split-up.
