| b2a6d51d | 15 | This driver provides support for virtio based paravirtual device |
| 3343660d AL |
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). | |

| 29 | This option enables building a transitional driver, supporting | |
| 30 | both devices conforming to Virtio 1 specification, and legacy devices. | |
| 31 | If disabled, you get a slightly smaller, non-transitional driver, | |
| 32 | with no legacy compatibility. | |
| 33 | ||
| 34 | So look out into your driveway. Do you have a flying car? If | |
| 35 | so, you can happily disable this option and virtio will not | |
| 36 | break. Otherwise, leave it set. Unless you're testing what | |
| 37 | life will be like in The Future. | |
