GATEWAY=192.168.1.1
DNS1=114.114.114.114
DNS2=8.8.4.4
增加BRIDGE=br0，删除IPADDR、NETMASK、GATEWAY、DNS
DEVICE=eth0
HWADDR=00:0C:29:DB:B2:28
TYPE=Ethernet
UUID=b2268aab-fa2e-49e9-bd67-2572f29e5790

#GATEWAY=192.168.1.1
#DNS1=114.114.114.114

[root@localhost network-scripts]# vi ifcfg-br0
DEVICE=eth0
HWADDR=00:0C:29:DB:B2:28
TYPE=Ethernet
UUID=b2268aab-fa2e-49e9-bd67-2572f29e5790

GATEWAY=192.168.1.1
DNS1=114.114.114.114
DNS2=8.8.4.4
修改DEVICE为br0，Type为Bridge，把eth0的网络设置设置到这里来
DEVICE=br0
TYPE=Bridge
ONBOOT=yes
BOOTPROTO=static
IPADDR=192.168.1.179
NETMASK=255.255.255.0
GATEWAY=192.168.1.1
DNS1=114.114.114.114
DNS2=8.8.4.4
保存退出
[root@localhost network-scripts]# service network restart这一步我出现了问题，不过重启宿主机后就OK了。
