To examine the internal architecture of Windows virtualization, specifically detailing how the operating system runs on top of a hypervisor.
Architectural analysis of the Windows Hyper-V virtualization model and host execution stack.
Evaluation of underlying hardware features and inter-partition communication mechanisms, including VT-x, SLAT, and VMBus.
Enabling Hyper-V relocates the primary host Windows operating system into a privileged root partition running directly atop the hypervisor rather than bare metal.
Partition isolation, memory management, and hardware communication depend on hardware-assisted virtualization (VT-x), Second Level Address Translation (SLAT), and the high-speed VMBus transport.

Implication

Architectural review details root partition execution in Windows Hyper-V environments, highlighting the foundational roles of hardware acceleration.

Abstract

When you enable Hyper-V, the host Windows itself runs on top of the hypervisor as the root partition. This article explains the foundations of virtualization through the roles of VT-x, SLAT, and VMBus.
