Flavor

  1. 載入管理者 admin 環境變數。 
    [root@ip110 ~]# . admin.token
[root@ip110 ~]<admin>#
  2. 查看 flavor set 命令，沒有重新命名的選項。 
    [root@ip110 ~]<admin># openstack help flavor set
usage: openstack flavor set [-h] [--no-property] [--property <key=value>]
                            [--project <project>]
                            [--project-domain <project-domain>]
                            <flavor>

Set flavor properties

positional arguments:
  <flavor>              Flavor to modify (name or ID)

optional arguments:
  -h, --help            show this help message and exit
  --no-property         Remove all properties from this flavor (specify both
                        --no-property and --property to remove the current
                        properties before setting new properties.)
  --property <key=value>
                        Property to add or modify for this flavor (repeat
                        option to set multiple properties)
  --project <project>   Set flavor access to project (name or ID) (admin only)
  --project-domain <project-domain>
                        Domain the project belongs to (name or ID). This can
                        be used in case collisions between project names
                        exist.
  3. 載入用戶 demo 環境變數。 
    [root@ip110 ~]<admin># . demo.token
  4. 列出 server，其中 ID 56d77ef3-2dd9-4482-975c-ed622dcce584 的 server，使用的 flavor 名稱為 fv_cirros。 
    [root@ip110 ~]<demo># openstack server list
+--------------------------------------+-----------+---------+-------------+---------+-----------+
| ID                                   | Name      | Status  | Networks    | Image   | Flavor    |
+--------------------------------------+-----------+---------+-------------+---------+-----------+
| 56d77ef3-2dd9-4482-975c-ed622dcce584 | cirros.m  | SHUTOFF | selfservice | cirros  | fv_cirros |
+--------------------------------------+-----------+---------+-------------+---------+-----------+
  5. 載入管理者 admin 環境變數。 
    [root@ip110 ~]<demo># . admin.token
  6. 列出 flavor，fv_cirros 的 ID 是 0。 
    [root@ip110 ~]<admin># openstack flavor list
+----+-----------+------+------+-----------+-------+-----------+
| ID | Name      |  RAM | Disk | Ephemeral | VCPUs | Is Public |
+----+-----------+------+------+-----------+-------+-----------+
| 0  | fv_cirros |   64 |    1 |         0 |     1 | True      |
| 1  | dyw.ce8   | 4096 |   30 |         0 |     2 | True      |
| 2  | fv_Win10  | 8192 |   30 |         0 |     4 | True      |

+----+-----------+------+------+-----------+-------+-----------+
  7. 刪除 ID 是 0 的 flavor。 
    [root@ip110 ~]<admin># openstack flavor delete 0
  8. 再列出 flavor，ID 是 0 的 flavor fv_cirros 已不存在。 
    [root@ip110 ~]<admin># openstack flavor list
+----+----------+------+------+-----------+-------+-----------+
| ID | Name     |  RAM | Disk | Ephemeral | VCPUs | Is Public |

+----+----------+------+------+-----------+-------+-----------+
  9. 重新新增一個 ID 是 0，名為 dyw.tiny 的 flavor，其 vcpus, ram, disk 都與先前的 fv_cirros 相同。 
    [root@ip110 ~]<admin># openstack flavor create --id 0 --vcpus 1 --ram 64 --disk 1 dyw.tiny
+----------------------------+----------+

| vcpus                      | 1        |
+----------------------------+----------+
  10. 載入用戶 demo 環境變數。 
    [root@ip110 ~]# . demo.token
  11. 再列出 flavor，ID 是 0 的 flavor 名為 dyw.tiny。 
    [root@ip110 ~]<demo># openstack flavor list
+----+----------+------+------+-----------+-------+-----------+
| ID | Name     |  RAM | Disk | Ephemeral | VCPUs | Is Public |
