修改 port 及密碼

1. instance cirros5 新增時使用 autoport，且沒設定連線密碼，現在使用 –property 選項設定 hw:port 及 hw:passwd 兩個 metadata。

   [root@ip110 ~]<demo># openstack server set --property hw:port=5995 --property hw:passwd=123321 cirros5
   

2. 查詢 instance cirros5 的 properties 有印出設定的值。

   [root@ip110 ~]<demo># openstack server show cirros5

3. 重新啟動 instance cirros5。

   [root@ip110 ~]<demo># openstack server reboot --hard cirros5
   

4. 再查詢 instance cirros5 的 xml 檔，autoport='no'，port 為 5995，passwd 為 123321。

   [root@ip110 ~]<demo># grep graphic /var/run/libvirt/qemu/instance-00000153.xml 
       <graphics type='spice' port='5995' autoport='no' listen='0.0.0.0' keymap='en-us' passwd='123321'>
       </graphics>
   [root@ip110 ~]<demo># grep graphic /etc/libvirt/qemu/instance-00000153.xml 
       <graphics type='spice' port='5995' autoport='no' listen='0.0.0.0' keymap='en-us' passwd='123321'>
       </graphics>
