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.
