现象：宿主机与虚拟机能互相ping通，宿主机能ping通外网，但虚拟机ping不通外网

原因：vmware的网关设置有误

1）查看linux网络配置信息

1.  
   [root@localhost ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0
2.  
   DEVICE=eth0
3.  
   TYPE=Ethernet
4.  
   UUID=4af77be9-c7c7-4245-acac-afc2b7f91e49
5.  
   ONBOOT=yes
6.  
   NM_CONTROLLED=yes
7.  
   BOOTPROTO=static
8.  
   HWADDR=00:50:56:26:15:DE
9.  
   DEFROUTE=yes
10.  
    PEERDNS=yes
11.  
    PEERROUTES=yes
12.  
    IPV4_FAILURE_FATAL=yes
13.  
    IPV6INIT=no
14.  
    NAME=”System eth0″
15.  
    IPADDR=192.168.137.3
16.  
    NETMASK=255.255.255.0
17.  
    GATEWAY=192.168.137.254 #linux网关与vmware网关需一致才行
18.  
    DNS1=114.114.114.114
19.  
    DNS2=10.111.1.2

2）点击：虚拟网络编辑器

3）点击：更改设置 → VMnet8 → NAT设置

4）保持vmware网关是否与linux网关一致

5）重启网卡

1.  
   [root@localhost ~]# service network restart
2.  
   Shutting down interface eth0: [ OK ]
3.  
   Shutting down loopback interface: [ OK ]
4.  
   Bringing up loopback interface: [ OK ]
5.  
   Bringing up interface eth0: Determining if ip address 192.168.137.3 is already in use for device eth0… [ OK ]

6）ping通百度

1.  
   [root@localhost ~]# ping baidu.com
2.  
   PING baidu.com (110.242.68.66) 56(84) bytes of data.
3.  
   64 bytes from 110.242.68.66: icmp_seq=1 ttl=128 time=60.3 ms
4.  
   64 bytes from 110.242.68.66: icmp_seq=2 ttl=128 time=64.3 ms
