	  Say Y here to get to see options for using your Linux host to run other
	  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.

	---help---
	  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 CONFIG_M here: the module
	  will be called kvm.

	  If unsure, say N.

config CONFIG_KVM_S390_UCONTROL
	bool "Userspace controlled virtual machines"
	depends on CONFIG_KVM
	---help---
	  Allow CAP_SYS_ADMIN users to create CONFIG_KVM virtual machines that are
	  controlled by userspace.

	  If unsure, say N.

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