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.

help
Support hosting paravirtualized guest machines using the SIE
virtualization capability on the mainframe. This should work
on any 64bit machine.
This module provides access to the hardware capabilities through
a character device node named /dev/kvm.
To compile this as a module, choose M here: the module
will be called kvm.
If unsure, say N.

help
Allow CAP_SYS_ADMIN users to create KVM virtual machines that are
controlled by userspace.
If unsure, say N.
