Hi,
As you're on a Windows 10 host, check your vmware.log file.
Look for a line:
"Monitor Mode"
Then check its value.
Most of the time when people complain about things like performance or not nested guest features.. that line says: ULM
(User Level Mode)
which means that your host OS is running as a VM already and all VM's are running using Microsoft Windows hypervisor API.
Only when it returns CPL0 you're using the good old VMware hypervisor.
