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 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.
# OK, it's a little counter-intuitive to do this, but it puts it neatly under
# the virtualization menu.
