  17        ---help---
  18          This drivers provides support for virtio based paravirtual device
  19          drivers over PCI.  This requires that your VMM has appropriate PCI
  20          virtio backends.  Most QEMU based VMMs should support these devices
  21          (like KVM or Xen).
  22
  23          Currently, the ABI is not considered stable so there is no guarantee
  24          that this version of the driver will work with your VMM.

  26          If unsure, say M.

  32        ---help---
  33         This driver supports increasing and decreasing the amount
  34         of memory within a KVM guest.
  35
  36         If unsure, say M.

  44         This drivers provides support for memory mapped virtio
  45         platform device driver.

  52        ---help---
  53         Allow virtio-mmio devices instantiation via the kernel command line
  54         or module parameters. Be aware that using incorrect parameters (base
  55         address in particular) can crash your system - you have been warned.
  56         See Documentation/kernel-parameters.txt for details.

  58         If unsure, say 'N'.
