	  other 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

	---help---
	  Support running unmodified 440 guest kernels in virtual machines on
	  440 host processors.

	  This module provides access to the hardware capabilities through
	  a character device node named /dev/kvm.

	depends on KVM
	---help---
	  Calculate elapsed time for every exit/enter cycle. A per-vcpu
	  report is available in debugfs kvm/vm#_vcpu#_timing.
	  The overhead is relatively small, however it is not recommended for
	  production environments.

	  If unsure, say N.
