Subject CS SSVM网络不通
Date Sat, 04 May 2013 05:18:21 GMT
HI:
KVM主机网络配置:
物理网卡:ifcfg-em1  ifcfg-em2  ifcfg-em3
桥接: ifcfg-cloudbr0 ifcfg-cloudbr1  ifcfg-cloudbr2

具体设置:
more ifcfg-em1
DEVICE=em1
ONBOOT=yes
BOOTPROTO=none
HOTPLUG=no
TYPE=Ethernet
BRIDGE=cloudbr0

more ifcfg-cloudbr0
DEVICE=cloudbr0
ONBOOT=yes
TYPE=Bridge
BOOTPROTO=none
DEEROUTE=yes
DELAY=5
STP=yes
IPADDR=10.10.50.1
NETMASK=255.255.255.0
GATEWAY=10.10.50.250
DNS1=172.20.1.250

more ifcfg-em2  
DEVICE=em2
ONBOOT=yes
BOOTPROTO=none
HOTPLUG=no
TYPE=Ethernet
BRIDGE=cloudbr1

more ifcfg-cloudbr1
DEVICE=cloudbr1
ONBOOT=yes
TYPE=Bridge
BOOTPROTO=none
DELAY=5
STP=yes
IPADDR=10.10.60.1
NETMASK=255.255.255.0

KVM主机上ping 10.10.60.250
 ping 10.10.60.250
PING 10.10.60.250 (10.10.60.250) 56(84) bytes of data.

SSVM的公网IP无发ping通: 
公用 IP 地址10.10.60.210

登陆该SSVM,查看路由:

到默认网关不通:
root@v-2-VM:~# ping  10.10.60.250

这个网络应该怎么排查??
