   4           This option is selected by any driver which implements the virtio
   5           bus, such as CONFIG_VIRTIO_PCI, CONFIG_VIRTIO_MMIO, CONFIG_LGUEST,
   6           CONFIG_RPMSG or CONFIG_S390_GUEST.

  15           This drivers provides support for virtio based paravirtual device
  16           drivers over PCI.  This requires that your VMM has appropriate PCI
  17           virtio backends.  Most QEMU based VMMs should support these devices
  18           (like KVM or Xen).

  20           Currently, the ABI is not considered stable so there is no guarantee
  21           that this version of the driver will work with your VMM.

  31          of memory within a KVM guest.

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

  54          If unsure, say 'N'.
