创建自定义的flavor
格式：nova flavor-create --is-public true FLAVOR_NAME FLAVOR_ID RAM_IN_MB ROOT_DISK_IN_GB NUMBER_OF_VCPUS
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
[root@cc07 ~]# nova flavor-show boshen_ram_1024_disk_1_vcpus_1
+----------------------------+------------------------------------------------+
| Property | Value |
+----------------------------+------------------------------------------------+
| OS-FLV-DISABLED:disabled | False |
| OS-FLV-EXT-DATA:ephemeral | |
| disk | |
| extra_specs | {"aggregate_instance_extra_specs:ssd": "true"} |
| id | boshen_ram_1024_disk_1_vcpus_1 |
| name | boshen_ram_1024_disk_1_vcpus_1 |
| os-flavor-access:is_public | True |
| ram | |
| rxtx_factor | 1.0 |
| swap | |
| vcpus | |
+----------------------------+------------------------------------------------+
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
