Virtual I/O Device (#VIRTIO) Version 1.0 Committee Specification 03 published by the VIRTIO TC
OASIS is pleased to announce the approval and publication of a new Committee Specification by the members of the VIRTIO TC:
Virtual I/O Device (VIRTIO) Version 1.0
Committee Specification 03
02 August 2015
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.
Description of the TC:
The goal of the OASIS Virtual I/O Device (VIRTIO) TC is to simplify virtual devices, making them more extensible and more recognizable.
The TC intends to define formal specifications for virtual device buses (including PCI) for a variety of devices, including network devices. Specification development will be based upon the "Virtio PCI Card Specification" v0.9.5, seeking solutions that support portability, simplicity, least-surprise for driver authors, extensibility, and performance. The specification will also document existing implementations and practice.

Members of the OASIS Virtual I/O Device (VIRTIO) TC  approved this specification by Special Majority Vote. The specification had been released for public review as required by the TC Process . The vote to approve as a Committee Specification passed , and the document is now available online in the OASIS Library as referenced above.
Our congratulations to the TC on achieving this milestone and our thanks to the reviewers who provided feedback on the specification drafts to help improve the quality of the work.
