| This document describes the specifications of the ``virtio'' family of |
| devices. These devices are found in virtual environments, yet by |
| design they look like physical devices to the guest |
| within the virtual machine - and this |
| document treats them as such. This similarity allows the guest to use standard |
| drivers and discovery mechanisms. |
| |
| The purpose of virtio and this specification is that virtual |
| environments and guests should have a straightforward, efficient, |
| standard and extensible mechanism for virtual devices, rather |
| than boutique per-environment or per-OS mechanisms. |
