bool "Virtualization"
---help---
Say Y here to get to see options for using your Linux host to run
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.

---help---
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.

default 0
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.

---help---
Adds support for a hardware assisted, in-kernel GIC emulation.
