I wonder how this is supposed to work on real systems. Shouldn't the dt
blob be filled out with the correct number of CPUs at the time you start
the guest? This change looks like you just make all guests use a hardcoded
set of two CPUs instead of just one, but you probably want to allow any
number between 1 and the number of physically present cores.
