Auotport 新增 Instance

1. 載入用戶 demo 環境變數。

   [root@ip110 ~]# . demo.token 
   [root@ip110 ~]<demo>#
   

2. 查詢可用 flavor。

   [root@ip110 ~]<demo># openstack flavor list
   +----+-----------+------+------+-----------+-------+-----------+
   | ID | Name      |  RAM | Disk | Ephemeral | VCPUs | Is Public |
   +----+-----------+------+------+-----------+-------+-----------+
   | 0  | dyw.tiny  |   64 |    1 |         0 |     1 | True      |
   | 1  | dyw.ce8   | 4096 |   30 |         0 |     2 | True      |
   | 2  | dyw.large | 8192 |   16 |         0 |     4 | True      |
   | 3  | dyw.csa   | 2048 |   16 |         0 |     2 | True      |
   +----+-----------+------+------+-----------+-------+-----------+
   

3. 查詢 flavor dyw.tiny 的各欄位值，沒有 extra_specs 設定。

   [root@ip110 ~]<demo># openstack flavor show dyw.tiny
   +----------------------------+----------+
   | Field                      | Value    |
   +----------------------------+----------+
   | OS-FLV-DISABLED:disabled   | False    |
   | OS-FLV-EXT-DATA:ephemeral  | 0        |
   | access_project_ids         | None     |
   | disk                       | 1        |
   | id                         | 0        |
   | name                       | dyw.tiny |
   | os-flavor-access:is_public | True     |
   | properties                 |          |
   | ram                        | 64       |
   | rxtx_factor                | 1.0      |
   | swap                       |          |
   | vcpus                      | 1        |
   +----------------------------+----------+
   

4. 使用 flavor dyw.tiny 新增 instance cirros2。

   [root@ip110 ~]<demo># openstack server create --flavor dyw.tiny \
   --image cirros5 --nic net-id=6ed4de53-ecc1-4c79-a9d2-8e511b26557a \
   --security-group default --availability-zone nova:ip110:ip110 \
   cirros2 --wait
   +-----------------------------+------------------------------------------------+
   | Field                       | Value                                          |
   +-----------------------------+------------------------------------------------+
   | OS-DCF:diskConfig           | MANUAL                                         |
   | OS-EXT-AZ:availability_zone | nova                                           |

   | OS-SRV-USG:terminated_at    | None                                           |

5. 載入管理者 admin 的環境變數，查詢 instance cirros2 的 xml 檔名稱為 instance-0000014f。

   [root@ip110 ~]<demo># . admin.token 
   [root@ip110 ~]<admin># nova list --all --fields=name,instance_name,status | grep cirros2
   | 62f81add-c3ca-4023-9bd4-a687116a7c8c | cirros2  | instance-0000014f | ACTIVE  |
   

6. 查詢 instance-0000014f.xml 得知，其使用自動取得的 5902 埠號，沒有設定連線密碼。

   [root@ip110 ~]<admin># grep graphic /var/run/libvirt/qemu/instance-0000014f.xml 
         <graphics type='spice' port='5902' autoport='yes' listen='0.0.0.0' keymap='en-us'>
         </graphics>
   [root@ip110 ~]<admin># grep graphic /etc/libvirt/qemu/instance-0000014f.xml 
       <graphics type='spice' autoport='yes' listen='0.0.0.0' keymap='en-us'>
       </graphics>
