Re: THREARIPPER system ..wrong core count
Can we see a VBox.log?
Do NOT send me Personal Messages (PMs) for troubleshooting, they are simply deleted.
Do NOT reply with the "QUOTE" button, please use the "POST REPLY", at the bottom of the form.
If you obfuscate any information requested, I will obfuscate my response. These are virtual UUIDs, not real ones.

No disparity. Not a regression. Can you show a host CPU tool reporting anything other than 6 physical cores?VirtualBox 5.2.0_RC1 wrote: 00:00:00.444809 CPUM: Logical host processors: 24 present, 24 max, 24 online, online mask: 0000000000ffffff

Ah, I hadn't noticed it was Ryzen.
