THREARIPPER system ..wrong core count

[Knudch]

See BUG https://www.virtualbox.org/ticket/17131

On a 1920x (12 physical cores, 24 virtual) virtualbox says 6/12 cores

Can we see a VBox.log?

No disparity. Not a regression. Can you show a host CPU tool reporting anything other than 6 physical cores?

If some physical core were disabled fx. in bios there will never be 24 logical cores
