I reverted to 6.1.18 and confirmed the issue is not present in this version, with low to minimal VMM Load. I tested and am not seeing the issue on a Ryzen 5 3400G host at this time. I have performed the same test with multiple vCPUs with 6.1.20, and 6.1.24 and the VMM Load is low in all these cases on a Ryzen host. All hosts tested are running Windows 10 x64. Tested and confirmed issue with Windows 10 x64 and Debian x86-64 guests on Intel 3rd gen Core i5, Core i7 5820K, Xeon E5-1620 v2, and Xeon E5-2620 v4 CPUs.",defect,new,VMM,VirtualBox 6.1.20,,,,Windows,Windows
