Problems in guest settings with too many CPUs present at the host.

Description
If there are more than 32 CPU cores present at the host computer, the guest settings CPU-slider-bar shows only red, but the slider is slidable anyway.
After limiting the number of available cores of the host to 32 or less, the guest settings seem to act normal.
As the host (IBM System X3850) has four 10-core-XEON 8870 CPUs, there are 40 cores (80 threads) altogether, which I would like to use entirely.
Note:
See TracTickets
for help on using tickets.
I got a hint at the Oracle VirtualBox forum to add a log here. I will do later, as my system is actually running and the configuration cannot be modified at the moment. But I can assure this bug is a general bug, as it could be verified on every multi-core machine >32 cores.
