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. 64 bytes from 10.10.60.250: icmp_seq=1 ttl=255 time=2.66 ms 64 bytes from 10.10.60.250: icmp_seq=2 ttl=255 time=0.737 ms 64 bytes from 10.10.60.250: icmp_seq=3 ttl=255 time=0.745 ms 64 bytes from 10.10.60.250: icmp_seq=4 ttl=255 time=1.19 ms 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： root@v-2-VM:~# route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 172.20.1.250 10.10.40.250 255.255.255.255 UGH 0 0 0 eth1 10.10.60.0 0.0.0.0 255.255.255.0 U 0 0 0 eth2 10.10.40.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1 169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth0 0.0.0.0 10.10.60.250 0.0.0.0 UG 0 0 0 eth2 到默认网关不通： root@v-2-VM:~# ping 10.10.60.250 PING 10.10.60.250 (10.10.60.250): 56 data bytes 64 bytes from v-2-VM (10.10.60.210): Destination Host Unreachable Vr HL TOS Len ID Flg off TTL Pro cks Src Dst Data 4 5 00 5400 0000 0 0040 40 01 c9ac 10.10.60.210 10.10.60.250 64 bytes from v-2-VM (10.10.60.210): Destination Host Unreachable Vr HL TOS Len ID Flg off TTL Pro cks Src Dst Data 4 5 00 5400 0000 0 0040 40 01 c9ac 10.10.60.210 10.10.60.250 这个网络应该怎么排查？？ waydee.chen
