VirtualBox does not report the correct # of host CPUs

[JMH1]

The version of VirtualBox I recently upgraded to (4.3.6) recognizes my host computer as having 2 CPUs.

However, it has 4, as past versions have been able to detect successfully.

I am running an Intel Core i3-2330M @ 2.20 GHz. It is a Sony Vaio.

Your CPU has two physical cores with 2 Hyperthreads per core, see ​here.
