配置虚拟机连接网络
首先确保NetworkManager服务正常运行

[root@administrator ~]# ping baidu.com
ping: unknown host baidu.comPING百度无法PING通，下面开始配置
两种配置方式：修改配置文件/使用图形界面工具
- 修改网卡配置文件
打开配置文件[root@administrator ~]# vim /etc/sysconfig/network-scripts/ifcfg-eno16777736
修改前的原配置文件TYPE=Ethernet BOOTPROTO=dhcp DEFROUTE=yes PEERDNS=yes PEERROUTES=yes IPV4_FAILURE_FATAL=no IPV6INIT=yes IPV6_AUTOCONF=yes IPV6_DEFROUTE=yes IPV6_PEERDNS=yes IPV6_PEERROUTES=yes IPV6_FAILURE_FATAL=no NAME=eno16777736 UUID=ea5c55cd-2fcf-4ed8-a31d-90e86fe56925 DEVICE=eno16777736 ONBOOT=no
修改后的配置文件TYPE=Ethernet #static/none/dhcp 桥接模式设置为dhcp即可 BOOTPROTO=dhcp DEFROUTE=yes PEERDNS=yes PEERROUTES=yes IPV4_FAILURE_FATAL=no IPV6INIT=yes IPV6_AUTOCONF=yes IPV6_DEFROUTE=yesgi IPV6_PEERDNS=yes IPV6_PEERROUTES=yes IPV6_FAILURE_FATAL=no NAME=eno16777736 UUID=ea5c55cd-2fcf-4ed8-a31d-90e86fe56925 DEVICE=eno16777736 #启用 ONBOOT=yes
重启网络服务[root@administrator ~]# systemctl restart network
再次PING百度，虚拟机已经能正常上网[root@administrator ~]# ping baiu.com PING baiu.com (222.76.218.234) 56(84) bytes of data. 64 bytes from baiu.com (222.76.218.234): icmp_seq=1 ttl=119 time=52.1 ms 64 bytes from baiu.com (222.76.218.234): icmp_seq=2 ttl=119 time=133 ms 64 bytes from baiu.com (222.76.218.234): icmp_seq=3 ttl=119 time=52.1 ms 64 bytes from baiu.com (222.76.218.234): icmp_seq=4 ttl=119 time=50.7 ms 64 bytes from baiu.com (222.76.218.234): icmp_seq=5 ttl=119 time=54.0 ms 64 bytes from baiu.com (222.76.218.234): icmp_seq=6 ttl=119 time=53.3 ms ^C --- baiu.com ping statistics --- 6 packets transmitted, 6 received, 0% packet loss, time 5009ms rtt min/avg/max/mdev = 50.727/65.890/133.046/30.051 ms
