+         operating systems inside virtual machines (guests).
+         This option alone does not add any kernel code.
+
+         If you say N, all options in this submenu will be skipped and disabled.

+         Support hosting fully virtualized guest machines using hardware
+         virtualization extensions.  You will need a fairly recent
+         processor equipped with virtualization extensions. You will also
+         need to select one or more of the processor modules below.
+
+         This module provides access to the hardware capabilities through
+         a character device node named /dev/kvm.
+
+         To compile this as a module, choose M here: the module
+         will be called kvm.
+
+         If unsure, say N.

+         Provides support for KVM on Intel processors equipped with the VT
+         extensions.
+
+         To compile this as a module, choose M here: the module
+         will be called kvm-intel.

+         Provides support for KVM on AMD processors equipped with the AMD-V
+         (SVM) extensions.
+
+         To compile this as a module, choose M here: the module
+         will be called kvm-amd.

+       bool "KVM legacy PCI device assignment support"

+         Provide support for legacy PCI device assignment through KVM.  The
+         kernel now also supports a full featured userspace device driver
+         framework through VFIO, which supersedes much of this support.
+
+         If unsure, say Y.
