OASIS members and other interested parties,
OASIS and the OASIS Virtual I/O Device (VIRTIO) TC are pleased to announce that Virtual I/O Device (VIRTIO) Version 1.1 is now available for public review and comment.
This document describes the specifications of the âvirtioâ family of devices. TheseÂ 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.
