Er no, let me try that again:

In my proposed design, the stub needs to know where all breakpoints are, HW or 
SW. (That means it must implement Z0/Z1.)

However, KVM itself doesn't need to know any of that: all breakpoints are 
referred to the stub for handling, and the stub will notify KVM if further 
action is needed in-kernel.
