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

  43. Provides support for KVM on Intel processors equipped with the VT
  44. extensions.

  60. audit KVM MMU at runtime.
