请教XEN的网络桥接配置问题

shy9000 · 发表于 2011-1-30 21:47:34

XEN搭建完成,VPS也是正常的,可是外部ping不了VPS内部,VPS内部也ping不了外部.
已经把iptables给stop了,然后开启了ipv4_forward,并重启过一次,请问还需要做什么才能够使XEN子VPS能够接收到外部的网络
附上ifconfig

[root@node1 ~]# ifconfig

再附上

[root@node1 ~]# brctl show
bridge name    bridge id             STP enabled    interfaces
xenbr0       8000.feffffffffff    no             vifvm101.0
                                                      peth0
                                                      vif0.0

配置都检查过了,VPS也能够正常开启,就是没有网络

补上一句,我看了日志,似乎没有啥错误提示

额，不懂技术了。。。。。代码一多我就晕。。。。

Proxy ARP ?

Proxy ARP ?

参数调整后重启,依旧失败

虚拟机配置贴上来看看
注意检查一下设置的网桥

网桥检查过了,虚拟机的配置应该是正常的,待会儿我重做一下机器的系统重做环境

shy9000 · 发表于 2011-1-31 00:50:42

虚拟机除了ifconfig之外还要哪些配置?

wishour · 发表于 2011-1-31 01:02:26

从来都自动分配的飘过

子机器的ifconfig

[root@www ~]# ifconfig
eth0 Link encap:Ethernet HWaddr 00:16:3E:64:E6:61
