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.
