+ 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
