the blue area represents userspace code. At the bottom of the stack resides the hypervisor – the core of the virtualization engine, controlling execution of the virtual machines and making sure they do not not conflict with each other or whatever the host computer is doing otherwise. On top of the hypervisor, additional internal modules provide extra functionality. For example, the RDP server, which can blocks. This API, which we call the "Main API", exposes the entire feature set of the virtualization engine below. It is completely documented in this SDK Reference – see chapter 5, Classes (interfaces)
