解决办法：  
  
首先，打开/etc/udev/rules.d/70-persistent-net.rules内容如下：  
  
\# vi /etc/udev/rules.d/70-persistent-net.rules  
\# This file was automatically generated by the /lib/udev/write\_net\_rules  
\# program, run by the persistent-net-generator.rules rules file.  
\#  
\# You can modify it, as long as you keep each rule on a single  
\# line, and change only the value of the NAME= key.  
\# PCI device 0x1022:0x2000 (pcnet32)  
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?\*", ATTR\{address\}=="00:0c:29:8f:89:97", ATTR\{type\}=="1", KERNEL=="eth\*", NAME="eth0"  
\# PCI device 0x1022:0x2000 (pcnet32)  
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?\*", ATTR\{address\}=="00:00:27:a1:fe:fd", ATTR\{type\}=="1", KERNEL=="eth\*", NAME="eth1"  
  
  
记下eth1网卡的mac地址00:0c:29:50:bd:17  
接下来修改ifcfg-eth0配置  
\# vi /etc/sysconfig/network-scripts/ifcfg-eth0  
  
将 DEVICE="eth0"  改成  DEVICE="eth1"  ,  
将 HWADDR="00:0c:29:8f:89:97" 改成上面的mac地址  HWADDR="00:00:27:a1:fe:fd"

最后，重启网络  
\# service network restart  
或者  
\# /etc/init.d/network restart  
  
  
ping下发现 正常了
