另外有个恐怕是白痴级别的问题，启动的时候我看到说eth1 ok，eth2 ok，启动以后事实上eth2是没有的，只有eth0 和eth1 是怎么回事？

哦，忘了ifconfig -a eth0了。。。。。。需要？需要的话我再重启下

jodgen

wenhq 发表于 2013-05-20 11:02
ifconfig -a 输出.

好的，马上再去重启

奇怪，KVM也不行，别的linux机器可以kvm的啊，用的Avocent DSR2035

重启以后的ifconfig -a

你在那里ping 10.1.0.40?
麻烦贴以下route -n 2种情况下的.

你在那里ping 10.1.0.40?
麻烦贴以下route -n 2种情况下的.

ping自己的IP，始终都没有问题的

route -n 也没有什么区别，不过ifcfg-eth2这个文件里的gateway顺序是否有关系，应该是没有关系的。另外我前面说的启动时看到eth1 ok和eth2 ok的问题也明白了。

eth1，也就是192段的地址是不需要网关的，它就是一个简单的内部局域网。

增加这个然后重启试试。
