Absolutely not.  It would always fetch HEAD from the KVM tool repo.  A 
submodule ties each supermodule commit to a particular submodule commit.

But I'm pretty certain that, when testing 3.2 with KVM tool in a couple 
of years, I want all the shining new features you added in this time; I 
don't want the old end-2011 code.  Same if I'm bisecting kernels, I 
don't want to build KVM tool once per bisection cycle, do I?
