	  If you say N, all options in this submenu will be skipped and

	  This module provides access to the hardware capabilities through

	help
	  Static number of max supported virtual CPUs per VM.

	  If you choose a high number, the vcpu structures will be quite
	  large, so only choose a reasonable number that you expect to
	  actually use.
