NVMM(4) Device Drivers Manual NVMM(4)

nvmm — NetBSD Virtual Machine Monitor

The nvmm driver provides kernel support for hardware-accelerated virtualization. It is made of a generic MI frontend, to which MD backends can be plugged to implement the core virtualization.

In practice, nvmm is used by the libnvmm(3) API to implement hypervisors.

The following backends are supported:

Note that for VMX support, the CPU must also support "VMX Unrestricted Guest", which is only present if Extended Page Tables (EPT) is supported. The earliest CPU family with this feature is Westmere, and not all later CPUs have it.

The nvmm driver was written by Maxime Villard.
