.Dd July 30, 2023 .Dt NVMM 4 .Os .Sh NAME .Nm nvmm .Nd NetBSD Virtual Machine Monitor .Sh DESCRIPTION The .Nm 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.
p In practice, .Nm is used by the .Xr libnvmm 3 API to implement hypervisors. .Sh SUPPORT The following backends are supported: l -hyphen -compact -offset indent t x86-SVM, for x86 AMD CPUs t x86-VMX, for x86 Intel CPUs .El 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. .Sh SEE ALSO .Xr libnvmm 3 , .Xr nvmmctl 8 .Sh AUTHORS The .Nm driver was written by .An Maxime Villard .
