Kinda.  P-4's had the Hyper-threading technology which which took a single core processor and made the OS think there were 2 processors.  Virtual dual processors you could say.

The dual core/duo core are actually 2 processor cores on one chip.  So there are 2 physical cores.  No virtualizing involved.
