指定 port 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 cirros4，使用 –property 選項設定 hw:port 及 hw:passwd 兩個 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 \
   --property hw:port='5994' --property hw:passwd='123qwe' cirros4 --wait

3. 載入管理者 admin 的環境變數，查詢 instance cirros4 的 xml 檔名稱為 instance-00000152。

   [root@ip110 ~]<demo># . admin.token 
   [root@ip110 ~]<admin># nova list --all --fields=name,instance_name,status | grep cirros4
   | 1f1af534-e9fd-4748-bd14-0d6a00d4614a | cirros4  | instance-00000152 | ACTIVE  |
   

4. 查詢 instance-00000152.xml 得知，其使用設定的 5994 埠號，連線密碼為 123qwe，都符合要求。

   [root@ip110 ~]<admin># grep graphic /etc/libvirt/qemu/instance-00000152.xml 
       <graphics type='spice' port='5994' autoport='no' listen='0.0.0.0' keymap='en-us' passwd='123qwe'>
       </graphics>
   [root@ip110 ~]<admin># grep graphic /var/run/libvirt/qemu/instance-00000152.xml 
         <graphics type='spice' port='5994' autoport='no' listen='0.0.0.0' keymap='en-us' passwd='123qwe'>
         </graphics>
