CentOS虚拟机克隆后网卡配置问题

CentOS虚拟机克隆后网卡配置问题及解决。

CentOS虚拟机克隆,物理地址会冲突,于是自动新建了网卡eth1,无法启动网卡。
 
解决办法:   
 
方式1:
 
1)修改/etc/sysconfig/network-scripts/ifcfg-eth0 为 /etc/sysconfig/network-scripts/ifcfg-eth1
 
2)配置/etc/sysconfig/network-scripts/ifcfg-eth1
 
# 修改为eth1
 
DEVICE="eth1"
 
BOOTPROTO="static"
 
# 硬件地址取自eth1(通过“ifconfig -a”获取)
 
HWADDR="00:0C:29:91:42:2C"
 
MTU="1500"
 
NM_CONTROLLED="yes"
 
ONBOOT="yes"
 
IPADDR=192.168.152.101
 
NETMASK=255.255.255.0
 
GATEWAY=192.168.152.2 
 
3)service network restart
 
方式2:
 
1)修改/etc/udev/rules.d/70-persistent-net.rules
 
拷贝eth1的硬件地址到eth0
 
删除eth1信息
 
2)配置/etc/sysconfig/network-scripts/ifcfg-eth0
 
DEVICE="eth0"
 
BOOTPROTO="static"
 
HWADDR="00:0C:29:91:42:2C"
 
MTU="1500"
 
NM_CONTROLLED="yes"
 
ONBOOT="yes"
 
IPADDR=192.168.152.101
 
NETMASK=255.255.255.0
 
GATEWAY=192.168.152.2
 
3)reboot
 
方式3(未测试): 
 
1)删除/etc/udev/rules.d/70-persistent-net.rules
 
2)配置/etc/sysconfig/network-scripts/ifcfg-eth0
 
DEVICE="eth0"
 
BOOTPROTO="static"
 
HWADDR="00:0C:29:91:42:2C"
 
MTU="1500"
 
NM_CONTROLLED="yes"
 
ONBOOT="yes"
 
IPADDR=192.168.152.101
 
NETMASK=255.255.255.0
 
GATEWAY=192.168.152.2
 
3)reboot
