centos 6.2 NetworkManager的bug

这个bug以前遇到过，当时认为是自己配置的问题。
使用centos的NetworkManager给eth0配置多个网卡。
# cat /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE="eth0"
NM_CONTROLLED="yes"
ONBOOT=yes
HWADDR=08:00:27:52:86:B2
TYPE=Ethernet
BOOTPROTO=none
IPADDR=192.168.0.171
PREFIX=24
GATEWAY=192.168.0.254
IPADDR2=10.10.10.2
PREFIX2=8
DEFROUTE=yes
IPV4_FAILURE_FATAL=yes
IPV6INIT=no
NAME="System eth0"
UUID=5fb06bd0-0bb0-7ffb-45f1-d6edd65f3e03
运行ip a
显示

只有一块网卡
删除NetworkManager
yum remove NetworkManager NetworkManager-gnome NetworkManager-glib
还是使用老办法，创建ifcfg-eth0的虚拟配置文件
# cd /etc/sysconfig/network-scripts
# cp ifcfg-eth0 ifcfg-eth0:0
# vi ifcfg-eth0:0

BOOTPROTO=static
 BROADCAST=192.168.0.255
IPADDR=192.168.0.11
NETMASK=255.255.255.0
NETWORK=192.168.0.0
ONBOOT=yes
TYPE=Ethernet

重启网络
# /etc/init.d/network restart
或者
service  network restart
