OVF 1.1 was adopted in August 2011 by ISO/IEC JTC 1/SC 38 of the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC) as an International Standard ISO/IEC 17203. In January 2013, DMTF released the second version of the standard, OVF 2.0 which applies to emerging cloud use cases and provides important developments from OVF 1.0 including improved network configuration support and package encryption capabilities for safe delivery.ĪNSI has ratified OVF 1.1.0 as ANSI standard INCITS 469-2010. The DMTF subsequently released the OVF Specification V1.0.0 as a preliminary standard in September, 2008, and V1.1.0 in January, 2010. In September 2007 VMware, Dell, HP, IBM, Microsoft and XenSource submitted to the Distributed Management Task Force (DMTF) a proposal for OVF, then named 'Open Virtual Machine Format'. The unit of packaging and distribution is a so-called OVF Package which may contain one or more virtual systems each of which can be deployed to a virtual machine. The OVF standard is not tied to any particular hypervisor or instruction set architecture. The standard describes an 'open, secure, portable, efficient and extensible format for the packaging and distribution of software to be run in virtual machines'.

Open Virtualization Format ( OVF) is an open standard for packaging and distributing virtual appliances or, more generally, software to be run in virtual machines.
