driver.py 及 config 修改

1. 切換工作目錄。

   [root@ip110 ~]# cd /usr/lib/python2.7/site-packages/nova/virt/libvirt/
   [root@ip110 libvirt]#
   

2. 修改 driver.py：self._guest_add_video_device 函式增加引數 instance，判斷 instance.metadata 是否設定 hw:port，有則使用且 graphics.autoport=False。判斷 instance.metadata 是否設定 hw:posswd，有則使用此密碼。

4. 修改後必須重新啟動 openstack-nova-compute 服務才會生效。

   [root@ip110 libvirt]# systemctl restart openstack-nova-compute.service
