    执行命令： nova interface-detach **虚拟机ID PortID**
    nova interface-detach fbbff44d-a3e8-4575-8f67-1246307026b6 97b426b7-732a-4665-b5ad-c3f140ff4b19

    4：添加新网卡
    解绑后，在SC上查看虚拟机信息为虚拟机重新添加新网卡，然后返回在后面级联层控制节点主机上，查看当前添加的新网卡是否为主网卡

    5：检查新网卡信息
    查看网卡是否为主网卡命令：neutron port-show PortID

    6：检查新网卡信息
    查看回显信息，admin_state_up字段是否为true，true为主网卡，反之不是
    如新加网卡不是主网卡，则需要为当前网卡添加主网卡属性
    命令：neutron port-update PortID admin_state_up True
