类型模板(flavor) 在Openstack中，虚机硬件模板被称为类型模板(flavor)，包括RAM和硬盘大小，CPU核数等。标准安装后有5个缺省的类型。类型模板可以被有管理员权限的用户修改(修改的权限也可以被编辑，通过在nova-api 服务器上的/etc/nova/policy.json 文件中修改访问控制：compute_extension:flavormanage )。
类型模板定义了以下元素: 列 描述 ID 一个唯一的数字ID Name 描述性的名字。xx.size_name通常方式是不需要的，虽然有些第三方工具可能需要这么设置 Memory_MB 虚机内存(MB) Disk 虚拟启动硬盘的大小（GB）。这是个装载启动软件的非持久化的硬盘。当从一个持久化硬盘启动的时候就不需要了。 大小为 “0” 是一个特殊的大小，表示采用和启动软件镜像相同的大小。 Ephemeral 指定第二个非持久化硬盘的大小。这是一个空的，没有被格式化的硬盘，只在虚机存在的时候存在。 Swap 虚机的可选的交换分区空间 VCPUs 虚机中虚拟CPU的核数 RXTX_Factor 此可选属性让被创建的服务器有和其带有的网络硬件有不同的带宽。这个可变因子定义RXTX(输入输出)与网络硬件带宽的比例。 缺省值是1.0，也就是说，和硬件带宽相同。 Is_Public 布尔值，类型模板是只给租户内的用户用还是可以给其他租户使用（公开）。缺省为真，即公开。 extra_specs 附加的可选项，限制哪台主机可以运行某种类型模板。采用key/value值得方式，只有有相同key/value值得主机才能运行相关类型模板。
