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. | ||
