查看message中关于网络的一些日志，现实好像有个关于Profile_1驱动不存在

[root@openstack home]# cat /var/log/messages | grep network

查看 /etc/sysconfig/network-scripts/，确实多了一个ifcfg-Profile_1

[root@openstack home]# cd /etc/sysconfig/network-scripts/
[root@openstack network-scripts]# ls
ifcfg-Profile_1  ifdown-Team      ifdown-ippp  ifdown-routes  ifup-Team      ifup-eth   ifup-plip    ifup-sit          network-functions
ifcfg-enp1s0     ifdown-TeamPort  ifdown-ipv6  ifdown-sit     ifup-TeamPort  ifup-ippp  ifup-plusb   ifup-tunnel       network-functions-ipv6
ifcfg-lo         ifdown-bnep      ifdown-isdn  ifdown-tunnel  ifup-aliases   ifup-ipv6  ifup-post    ifup-wireless
ifdown           ifdown-eth       ifdown-post  ifup           ifup-bnep      ifup-isdn  ifup-routes  init.ipv6-global

删除该文件重新启动网络即回复正常
