nova floating-ip-associate f7ff6d3f-b998-45a7-b5f7-fd51963951e9 192.168.0.2

nova floating-ip-disassociate demo-instance1 192.168.0.1

 

4. 打开/关闭实例

nova start/stop demo-instance1

 

5. 查看实例位于哪一台宿主机

    a. nova show demo-instance1, 结果中的hostid即为宿主机id号

    b. cd /var/lib/nova/instances, 在计算节点上进入此文件夹,可以看到以实例id号命名的文件夹

 

6. nova host-list

 

7. 查看当前OpenStack版本号
