指定 port 新增 Instance

1. 載入管理者 admin 環境變數。

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

2. flavor dyw.tiny 新增 hw_set_port 及 hw_set_passwd 兩項 extra specs。

   [root@ip110 ~]<admin># openstack flavor set dyw.tiny \
   

3. 查詢 flavor dyw.tiny，properties 新增了 hw_set_port 及 hw_set_passwd 兩項 extra specs。

   --property hw_set_port=5999 --property hw_set_passwd='123qwe'
   [root@ip110 ~]<admin># openstack flavor show dyw.tiny

4. 載入用戶 demo 環境變數，使用 flavor dyw.tiny 新增 instance cirros3。

   [root@ip110 ~]<admin># . demo.token 
   [root@ip110 ~]<demo># openstack server create --flavor dyw.tiny --image cirros5 \
   --nic net-id=6ed4de53-ecc1-4c79-a9d2-8e511b26557a --security-group default \

5. 載入管理者 admin 環境變數，用 instance cirros3 的 id 查詢其 xml 檔為 instance-00000150。

   [root@ip110 ~]<demo># . admin.token 
   [root@ip110 ~]<admin># nova list --all --fields=name,instance_name,status | grep cirros3
   | 44267063-3f4f-4faf-813a-d4f367588934 | cirros3  | instance-00000150 | ACTIVE  |
   

6. 查詢 instance-00000150.xml 得知，其使用固定埠號 5999，且設定連線密碼 123qwe。

   [root@ip110 ~]<admin># grep graphic /etc/libvirt/qemu/instance-00000150.xml 
       <graphics type='spice' port='5999' autoport='no' listen='0.0.0.0' keymap='en-us' passwd='123qwe'>
       </graphics>
   [root@ip110 ~]<admin># grep graphic /var/run/libvirt/qemu/instance-00000150.xml  
         <graphics type='spice' port='5999' autoport='no' listen='0.0.0.0' keymap='en-us' passwd='123qwe'>
