NVMM(4)                 NetBSD Kernel Interfaces Manual                NVMM(4)


NAME

     nvmm -- NetBSD Virtual Machine Monitor


DESCRIPTION

     The nvmm driver provides kernel support for hardware-accelerated virtual-
     ization.  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)
