Previous to my HVMlite series that was true, and HVM guests were started
without setting any explicit CPU state (in fact we placed that horrible
jmp at 0x0, because the IP was by default set to 0x0). This is no longer
true, and now HVM guests require that a proper CPU context is loaded
before starting. I believe this is better, and this change helps enforce
this policy.
