nova flavor-list 命令显示可用风格的列表。创建 VM 实例时，您将使用风格的名称或 ID。要在风格列表中包括 extra-specs，请为 nova flavor-list 命令指定 --extra-specs 选项。有关 extra_specs 值的更多信息，请参见修改风格规范。
在下面的示例中，输出中省略了 RXTX_Factor 和 Is_Public 列以节省空间。有关这些列的信息，请参见《OpenStack Command-Line Interface Reference》（《OpenStack 命令行界面参考》）。

以下命令显示有关指定风格的详细信息。第一个版本的命令指定风格名称，而第二个版本指定风格 ID。这两个命令的输出完全相同。
$ nova flavor-show 'Oracle Solaris kernel zone - large'
