Notes to myself and to the community :

Can't run Nested Virtualisation on Windows when DeviceGuard is on

WMWare Workstation requires to have access to Intel VT-x and VT-x/EPT for Nested Virtualisation

(The same must be true for other type 2 hypervisors ; Ex: VirtualBox, QEMU, etc ...)

Use case :

ClusterHat
