Lguest seems to be rather unused these days. It has seen only patches ensuring it still builds the last two years and its official state is "Odd Fixes". Remove it in order to be able to clean up the paravirt code.

This option is selected by any driver which implements the virtio

bus, such as CONFIG_VIRTIO_PCI, CONFIG_VIRTIO_MMIO, CONFIG_RPMSG

|
|
select VIRTIO
|
|
---help---
|
|
This driver provides support for virtio based paravirtual device
|
|
drivers over PCI. This requires that your VMM has appropriate PCI
|
|
virtio backends. Most QEMU based VMMs should support these devices
|
|
(like KVM or Xen).

If unsure, say M.

---help---
|
|
Virtio PCI Card 0.9.X Draft (circa 2014) and older device support.
|
|
|
|
This option enables building a transitional driver, supporting
|
|
both devices conforming to Virtio 1 specification, and legacy devices.
|
|
If disabled, you get a slightly smaller, non-transitional driver,
|
|
with no legacy compatibility.
|
|
|
|
So look out into your driveway. Do you have a flying car? If
|
|
so, you can happily disable this option and virtio will not
|
|
break. Otherwise, leave it set. Unless you're testing what
|
|
life will be like in The Future.
|
|

If unsure, say Y.
