Nested Virtualization Architecture Layers

Nested virtualization is highly beneficial for creating isolated training environments and testing complex software deployments. By utilizing Hyper-V isolation, developers can run containerized applications with an extra layer of security. This capability relies on physical hardware features, specifically modern processors that support Intel VT-x or AMD-V virtualization extensions. The Azure hypervisor passes these hardware extensions directly down to the outer VM, enabling it to act as a host for inner guest VMs.
