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.
