Setting up a VMware vSphere Hypervisor 7.0 (ESXi 7.0) with Oracle VirtualBox (failed)

Open your Virtual Box and create a new VM:

Machine -> New...

After this wizard-driven creation process, the created VM must be modified so that virtualisation technologies can be run on it.

This is only possible via a CLI (PowerShell / CMD).

cd 'C:\Program Files\Oracle\VirtualBox\'
.\VBoxManage.exe modifyvm "VMwareNode1" --nested-hw-virt on

Mount ISO....

Start VM...

Start Installation...

I will still try to find a solution here.
For now, I just have to admit that this project has failed.
