   7 ## Introduction
   8
   9 NVMM is a Type-2 hypervisor, and hypervisor platform, that provides support for hardware-accelerated virtualization.
  10 A virtualization API is shipped in libnvmm(3), and allows existing emulators (e.g., QEMU) to easily create and manage virtual machines via NVMM.
  11
  12 NVMM can support up to 128 virtual machines, each having a maximum of 128 vCPUs and 127TB RAM.
  13 It works with both x86 AMD CPUs (SVM/AMD-V) and x86 Intel CPUs (VMX/VT-x).
  14
  15 NVMM was designed and written by Maxime Villard (m00nbsd.net), first appeared in NetBSD 9, and was ported to DragonFly 6.1 by Aaron LI (aly@).

  17 ## Design
  18
  19 NVMM has unique design properties, not currently found in other hypervisor solutions.
