Discussed OVF 's role in the life cycle of the common virtual appliance .

讨论了OVF在普通虚拟工具生命周期中的角色。

OVF can even represent multiple VMs in a single package .

OVF甚至可以表示单个包中的多个VM。

The steps to create a new OVF envelope are

创建新OVF信封的步骤如下

At its core , an OVF package is a distribution package that consists of the following

作为其核心，OVF包是一种分发包，它由以下内容组成

Zero to one OVF certification file ( . cert ) .

到1个OVF认证文件（.cert）。

In many cases , it may be desirable to create an OVF envelope from scratch .

在许多情况下，从零开始创建OVF信封是比较令人满意的。

The following sections highlight the various aspects and usage scenarios of the OVF composition tool .

以下各节列出了OVF复合工具各个方面的要点以及使用场景。

At this point you will have a skeleton OVF envelope opened within the new editor .

此时，您将在新编辑器中打开一个框架OVF信封。

The OVF composition tool supports both of these distribution formats thorough the services of Export processing .

OVF复合工具通过Export处理服务支持这两种分发格式。

Closely related to the previous topic are conformance levels which are be described by OVF .

与前一个课题密切相关的是OVF描述的一致性等级。

After this step , you will have the exported OVF package ready for distribution .

完成此步骤之后，导出的OVF包将准备用于分发。

For OVF TAR archives , the files are created in the following order inside the archive

对于OVFTAR归档，文件将按以下顺序在归档内容创建

The OCCI interface could be used to import and export Service definitions in an OVF format .

OCCI接口可以用于以OVF格式导入和导出服务定义。

Additionally , tools exist that provide conversion of older format VMs into the OVF .

另外，有一些工具可以将旧格式的VM转换为OVF。

It would be desirable to have these templates being described by an OVF representation as well .

最好也在OVF表现方式下定义这些模板。

One OVF descriptor file ( . ovf ) .

一个OVF描述符文件（.ovf）。

Service providers supporting service provisioning using OVF over OCCI need to take care that these levels are met .

支持在OCCI上使用OVF准备服务的服务供应商需要注意满足这些等级要求。

With OVF , you can securely package and distribute virtual appliances in an efficient way .

使用OVF，您可以安全有效地打包并分发虚拟设备。

The final step is to create a TAR archive that contains the images and the OVF .

最后一步是创建一个包含映像和OVF的TAR存档。

Ensure that conformance levels described in OVF are met in a setup with OCCI

确保OVF中描述的一致性等级在OCCI的搭建时得到满足

As a reference to how OVF packages can be produced in support of distribution , we present the following scenario .

为了演示如何生成OVF包以支持分发，我们给出了以下场景。

Bear in mind that the majority of the OVF metadata is to be added after the new file creation .

记住，大多数OVF元数据都将在新文件创建之后添加。

Create a new project ( or use an existing project ) to hold the OVF envelope files if one does not already exist .

创建一个新项目（或使用已有项目）来保存OVF信封文件（如果不存在的话）。

For best interoperability we would recommended that a MIME-type for OVF be registered .

为了达到最佳的互操作性，我们建议注册OVF的MIME类型。

To export an OVF package from the OVF composition tool , you select the file export menu command

要从OVF复合工具导出某个OVF包，请选择文件导出菜单命令

The growing development around virtual appliances will ultimately drive their continued growth , and new specifications like the OVF will certainly help .

随着围绕虚拟设备的开发不断深入，虚拟设备必然会不断发展，诸如OVF之类的新规范肯定会发挥应有的作用。

The following topics should be considered to enable a further integration of OVF and OCCI .

为了让OVF和OCCI进一步集成应该考虑下面的课题。

An OVF package can be represented as a set of files or as a single file using the TAR format .

可以将OVF包表示为一组文件或一个使用TAR格式的文件。

The OVF standard requires that the OVF file reside in the same directory as the virtual machine image .

OVF标准要求将OVF文件保存在虚拟机器映像所在的目录中。
