Then go do the experiment the OP wants and prove it.
Here is Ubuntu 19.10 running under VMware, called Ubuvm, with nesting enabled in VMware and 4 CPU-cores given to the VM. I ran the command kvm-ok in terminal to test if it finds HW VM-instructions enabled in the CPU and it does. On the same VM, I am running another Ubuntu 19.10 in a nested VM with 4 CPU-cores given to the VM and there I have also ran kvm-ok, which also finds HW VM-instructions enabled.
On both the first VM and then the nested VM I run sysbench (sysbench --threads=4 --cpu-max-prime=40000 --events=21000 --time=0 --test=cpu run) via ssh, just so display-processing doesn't cause any noticeable difference and.. well, there is very little difference in the results. There would be, if HW virtualization wasn't working correctly.
Would you like to insist for me to go deeper, or do you accept this?
