The OASIS Virtual I/O Device (VIRTIO) TC  members have recently approved a Committee Specification Draft (CSD) and submitted this specification for 30-day(*) public review:
Virtual I/O Device (VIRTIO) Version 1.0
Committee Specification Draft 01 / Public Review Draft 01
03 December 2013
This document describes the specifications of the "virtio" family of devices. These devices are found in virtual environments, yet by design they are not all that different from physical devices, and this document treats them as such. This 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.
This is the first public review draft, after months of hard work by the VIRTIO Technical Committee.
The goal of the OASIS Virtual I/O Device (VIRTIO) TC is to simplify virtual devices, making them more extensible and more recognizable.
The purpose of VIRTIO is to ensure that virtual environments and guests have a straightforward, efficient, standard, and extensible mechanism for virtual devices, rather than boutique per-environment or per-OS mechanisms.
Public Review Period:
