例子：

[root@cc07 ~]# nova flavor-create --is-public true boshen_ram_1024_disk_1_vcpus_1 boshen_ram_1024_disk_1_vcpus_1
+--------------------------------+--------------------------------+-----------+------+-----------+------+-------+-------------+-----------+

设置flavor的extra_specs属性

[root@cc07 ~]# nova flavor-key boshen_ram_1024_disk_1_vcpus_1 set aggregate_instance_extra_specs:ssd=true

创建flavor后，指定一个或多个键值对，让这些键值对与主机集群上的键值对匹配，范围为aggregate_instance_extra_specs。 在这种情况下，设置格式为：aggregate_instance_extra_specs：ssd = true键值对。

当用户请求具有 boshen_ram_1024_disk_1_vcpus_1 规格的实例时，调度程序仅考虑具有ssd = true键值对的主机

将flavor赋给tenant
