Auotport 新增 Instance

1. 載入用戶 demo 環境變數。

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

2. 使用 flavor dyw.tiny 新增 instance cirros5，沒有使用 –property 選項設定 metadata。

   [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 cirros5 --wait

3. 載入管理者 admin 的環境變數，使用 instance cirros5 的 xml 檔名稱為 instance-00000153。

   [root@ip110 ~]<demo># . admin.token 
   [root@ip110 ~]<admin># nova list --all --fields=name,instance_name,status | grep cirros5
   | c9a9f517-7e33-41dd-98eb-c95de8a11218 | cirros5  | instance-00000153 | ACTIVE  |
   

4. 查詢 instance-00000153.xml 得知，其使用自動取得的 5911 埠號，沒有設定連線密碼。

   [root@ip110 ~]<demo># grep graphic /var/run/libvirt/qemu/instance-00000153.xml
         <graphics type='spice' port='5911' autoport='yes' listen='0.0.0.0' keymap='en-us'>
         </graphics>
   [root@ip110 ~]<demo># grep graphic /etc/libvirt/qemu/instance-00000153.xml 
       <graphics type='spice' autoport='yes' listen='0.0.0.0' keymap='en-us'>
