这两天我在虚拟机OEL5.7 Linux环境装RAC时，一直未解决Prerequisite Checks的Task resolv.conf Integrity问题。请各位赐教！
版本：Oracle Database 11g R2（11.2.0.3）
Host环境：
Win7 SP1 x64 + VirtualBox 4.1.2
Guest环境：
两个主机rac1，rac2各配置2个网卡，皆以Bridged Adapter方式以Host的以太网卡相连。
系统： Oracle Enterprise Linux 5.7

在安装grid中的Prerequisite Checks步骤遇到Task resolv.conf Integrity问题一直未能解决。
用cluvfy进行检查，./runcluvfy.sh stage -pre crsinst -n rac1,rac2 -verbose发现如下问题（其它皆已passed，输出省略）：
