Nested deployement: Are parameters title confusing or is it just me?

Hi Communities,

Running ESXi 6.5, I was digging on 2 CPU parameters for my VMs:

1. Hardware virtualization: Expose Hardware assisted Virtualization to the guest OS
2. CPU/MMU Virtualization: Automatic/Hard CPU & Soft MMU/Soft CPU & Hard MMU/Both hard

I understood that we have two level/generations of native virtualized instructions here:

1. Hardware virtualization: use VT-X (or AMD-V) for my guest
2. CPU/MMU Virtualization: Use Intel EPT (or AMD-V Nested paging) for my guest

But, what is not clear is why we are mixing CPU in CPU/MMU Virtulization? the choice of "Hardware CPU (& {soft, hard} memory)" is about to use VT-X right? So if I choose Hardware CPU in 2) and not checking "Hardware virtualization" in 1), it's confusing right?

Furthermore, I have an esxi running on a Xeon(R) Gold 6126 (yeah), that have VT-X/EPT... And I can not choose Hardware MMU and CPU on parameter 2), even if I checked 1) !

Please enlight me community!

Thanks & have a nice day!
