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 1024 1 1 +--------------------------------+--------------------------------+-----------+------+-----------+------+-------+-------------+-----------+ | ID | Name | Memory_MB | Disk | Ephemeral | Swap | VCPUs | RXTX_Factor | Is_Public | +--------------------------------+--------------------------------+-----------+------+-----------+------+-------+-------------+-----------+ | boshen_ram_1024_disk_1_vcpus_1 | boshen_ram_1024_disk_1_vcpus_1 | 1024 | 1 | 0 | | 1 | 1.0 | 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 | 0 | | disk | 1 | | extra_specs | {} | | id | boshen_ram_1024_disk_1_vcpus_1 | | name | boshen_ram_1024_disk_1_vcpus_1 | | os-flavor-access:is_public | True | | ram | 1024 | | rxtx_factor | 1.0 | | swap | | | 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 | 0 | | disk | 1 | | 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 | 1024 | | rxtx_factor | 1.0 | | swap | | | vcpus | 1 | +----------------------------+------------------------------------------------+
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
