Cloned Red Hat/CentOS/ Linux Virtual Machines 出现“Device eth0 does not seem to be present”


$ vi /etc/udev/rules.d/70-persistent-net.rules

原来的内容

# This file was automatically generated by the /lib/udev/write_net_rules
# program, run by the persistent-net-generator.rules rules file.
#
# You can modify it, as long as you keep each rule on a single
# line, and change only the value of the NAME= key.

# PCI device 0x15ad:0x07b0 (vmxnet3) (custom name provided by external tool)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:50:56:87:00:21", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"

# PCI device 0x15ad:0x07b0 (vmxnet3)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:50:56:87:00:25", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"


删除最后面的一行

新的内容

SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:50:56:87:00:25", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"


修改 网卡的MAC地址为上面的 {address}=="00:50:56:87:00:25" 中的地址

$  vi /etc/sysconfig/network-scripts/ifcfg-eth0

找到 HWADDR,如果没有就添加

HWADDR="00:50:56:87:00:25"


重新启动

$ reboot

查看eth0是否启动

$ ifconfig
