NVMM(4)                      Device Drivers Manual                     NVMM(4)

NAME
     nvmm - NetBSD Virtual Machine Monitor

DESCRIPTION
     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.

SUPPORT
     The following backends are supported:
           -   x86-SVM, for x86 AMD CPUs
           -   x86-VMX, for x86 Intel CPUs
     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.

SEE ALSO
     libnvmm(3), nvmmctl(8)

AUTHORS
     The nvmm driver was written by Maxime Villard.
