i7 and number of cores

[ToddAndMargo]

Hi All,

The i7 processor has 4 cores and 8 virtual (Hyperthreaded) cores. When I tell virtual box to use 2 cores on my guest, what am I actually telling Virtual Box to do?

1) give 2 real cores to the guest?

or

2) give 1 core as 2 virtual cores?

or

3) give give 1 virtual core from a real core and a second virtual core from a different real core for a total of two?

Many thanks,
-T

I would assume (just guessing here) that it's #1...
