标准范围

开放虚拟化格式(OVF)规范描述了一种开放、安全、高效和用于打包和分发在虚拟系统中运行的软件的可扩展格式。OVF包支持可移植虚拟系统的创作和虚拟虚拟化平台之间的系统。此版本的规范（2.1）旨在允许在以下意义上使用OVF 2.x描述符的OVF 1.x工具:现有的OVF 1.x工具应该能够解析OVF 2.x描述符。如果依赖于2.x，现有的OVF 1.x工具应该能够给出警告/错误功能是正确操作所必需的。如果架构、文本或表之间出现冲突，则解决冲突的优先顺序是模式；然后发短信；然后是桌子。附图仅用于说明目的，并非规范性标准的一部分。表格可以约束文本，但不得与文本冲突。配置文件符合引用的CIM模式类（如果使用）。中包含的任何要求应满足引用的CIM模式类。如果出现冲突，CIM模式优先。该配置文件符合引用的OVF XML模式。它可以约束模式，但不应约束与之冲突。如果出现冲突，OVF XML模式优先。

The Open Virtualization Format (OVF) Specification describes an open, secure, efficient andextensible format for the packaging and distribution of software to be run in virtual systems.The OVF package enables the authoring of portable virtual systems and the transport of virtualsystems between virtualization platforms. This version of the specification (2.1) is intended to allowOVF 1.x tools to work with OVF 2.x descriptors in the following sense:Existing OVF 1.x tools should be able to parse OVF 2.x descriptors.Existing OVF 1.x tools should be able to give warnings/errors if dependencies to 2.xfeatures are required for correct operation.If a conflict arises between the schema, text, or tables, the order of precedence to resolve the conflictsis schema; then text; then tables. Figures are for illustrative purposes only and are not a normativepart of the standard.A table may constrain the text but it shall not conflict with it.The profile conforms to the cited CIM Schema classes where used. Any requirements contained in thecited CIM Schema classes shall be met. If a conflict arises the CIM Schema takes precedence.The profile conforms to the cited OVF XML Schema. It may constrain the schema but it shall notconflict with it. If a conflict arises the OVF XML Schema takes precedence.
