Open Virtualization Format (OVF) is an open standard for packaging and distributing virtual appliances or, more generally, software to be run in virtual machines. The standard describes an "open, secure, portable, efficient and extensible format for the packaging and distribution of software to be run in virtual machines". The OVF standard is not tied to any particular hypervisor or processor architecture. 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. == History == 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".〔(【引用サイトリンク】 DMTF Press Release on OVF submission 9/2007 )〕 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 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. ANSI has ratified OVF 1.1.0 as ANSI standard INCITS 469-2010. OVF 1.1 was adopted as an International Standard in August 2011 by the Joint Technical Committee 1 (JTC 1) of the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC) .〔(【引用サイトリンク】 DMTF Gains International Recognition with Two ISO/IEC Standards )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Open Virtualization Format」の詳細全文を読む スポンサード リンク
