Checked the manual for what you need to use SMP? According to
http://processorfinder.intel.com/detail ... Spec=SLAY7, you don't have VT-x, which is essential for SMP.

Because VB uses hardware virtualization to make it available, VMWare uses ugly software hacks that even allows you to use 2 CPUs when you have a single core CPU in your computer. They 'simulate' a second core, while VB actually gives a real second core.
