define KernelPackage/kvm-x86/description
Support hosting fully virtualized guest machines using hardware
virtualization extensions. You will need a fairly recent
processor equipped with virtualization extensions. You will also
need to select one or more of the processor modules.
This module provides access to the hardware capabilities through
a character device node named /dev/kvm.
