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

disabled.

Support hosting virtualized guest machines. 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.

If unsure, say N.

Static number of max supported virtual CPUs per VM.

If you choose a high number, the vcpu structures will be quite

actually use.
