VMware Fusion, CPU cores confusion?

The number of cores you allocate in VMware Fusion doesn't directly correlate to physical cores -- to the virtual machine, Fusion presents the given number of "virtual" CPUs, but the instructions that the virtual machine passes to those CPUs may be executed on any of your machine's physical CPUs. The number of virtual CPUs given is just an abstraction; there's nothing preventing Fusion from, for example, telling Windows that it's got 16 cores even if your machine only has 4, though this wouldn't given any performance benefit because all 16 sets of instructions would have to be run on only the 4 available real cores.
