    Virtual Networking Management White Paper Version 1.0.0b

    Publication Date: November 8, 2011 DSP2025

    Status: Work in Progress

    Abstract

    Virtual networking enables virtual computer systems (a.k.a. virtual machines) to be networked together. This white paper describes virtual networking management standards developed by the DMTF. Specifically, this white paper provides an overview of the following:

    1. Extensions to the DMTF Common Information Model (CIM) for the Ethernet port resource virtualization and management of virtual networking components including virtual Ethernet ports, virtual Ethernet switches, and Edge Virtual Bridging (EVB) as defined by IEEE 802.1Qbg

    2. Network Port Profile XML Schema to abstractly represent networking attributes of a virtual computer system or a set of virtual computer systems

    3. Extensions to Open Virtualization Format (OVF) for the incorporation of Network Port Profiles
