VBox 5.1.28r117968 on FreeBSD only reveals 2 CPU's per guest

[lifeboy]

VBox 5.1.28r117968 only shows 2 CPU's even though many are available and assigned to a guest.

On the host: # sysctl hw.model hw.machine hw.ncpu hw.model: Intel(R) Xeon(R) CPU E5-1620 v3 @ 3.50GHz hw.machine: amd64 hw.ncpu: 8

On the Guest (UBuntu 14.04)

This is not unique to this host or guest. All our guests on difference hosts display this behaviour.
