解决如下：
查看复制虚拟机网卡信息如下：
1 root@jcfx-2 ~]# ifconfig 2 eth1 Link encap:Ethernet HWaddr 00:0C:29:CC:32:63 3 inet addr:192.168.72.11 Bcast:192.168.72.255 Mask:255.255.255.0 4 inet6 addr: fe80::20c:29ff:fecc:3263/64 Scope:Link 5 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 6 RX packets:17551 errors:0 dropped:0 overruns:0 frame:0 7 TX packets:166 errors:0 dropped:0 overruns:0 carrier:0 8 collisions:0 txqueuelen:1000 9 RX bytes:1303129 (1.2 MiB) TX bytes:63288 (61.8 KiB) 10 lo Link encap:Local Loopback 11 inet addr:127.0.0.1 Mask:255.0.0.0 12 inet6 addr: ::1/128 Scope:Host 13 UP LOOPBACK RUNNING MTU:16436 Metric:1 14 RX packets:8 errors:0 dropped:0 overruns:0 frame:0 15 TX packets:8 errors:0 dropped:0 overruns:0 carrier:0 16 collisions:0 txqueuelen:0 17 RX bytes:584 (584.0 b) TX bytes:584 (584.0 b）
具体需求是将eth1修改为eth0：
为什么eth0会变成eth1?
Linux distribution使用udev动态管理设备文件，并根据设备的信息对其进行持久化命名。udev会在系统引导的过程中识别网卡，将mac地址和网卡名称对应起来记录在udev的规则脚本中。而对于新的虚拟机，VMware会自动为虚拟机的网卡生成MAC地址，当你克隆或者重装虚拟机软件时，由于你使用的是以前系统虚拟硬盘的信息，而该系统中已经有eth0的信息，对于这个新的网卡，udev会自动将其命名为eth1（累加的原则），所以在你的系统启动后，你使用ifconfig看到的网卡名为eth1；
在RedHat中，udev记录网络规则的脚本为：/etc/udev/rules.d/70-persistent-net.rules
1 [root@jcfx-2 ~]# more /etc/udev/rules.d/70-persistent-net.rules 2 # This file was automatically generated by the /lib/udev/write_net_rules 3 # program, run by the persistent-net-generator.rules rules file. 4 # You can modify it, as long as you keep each rule on a single 5 # line, and change only the value of the NAME= key. 6 # PCI device 0x15ad:0x07b0 (vmxnet3) 7 SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:a0:25:f7", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0" 8 # PCI device 0x15ad:0x07b0 (vmxnet3) 9 SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:cc:32:63", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"
1 解决如下： 2 将70-persistent-net.rules脚本中多出来的eth1信息注销，并且修改原有的eth0的MAC地址信息，该信息与eth1的MAC信息保持一致，或者修改为别的MAC地址； 3 修改如下： 4 [root@jcfx-2 ~]# more /etc/udev/rules.d/70-persistent-net.rules 5 # This file was automatically generated by the /lib/udev/write_net_rules 6 # program, run by the persistent-net-generator.rules rules file. 7 # You can modify it, as long as you keep each rule on a single 8 # line, and change only the value of the NAME= key. 9 # PCI device 0x15ad:0x07b0 (vmxnet3) 10 SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:cc:32:63", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0" 11 # PCI device 0x15ad:0x07b0 (vmxnet3) 12 #SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:cc:32:63", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1" 13 最后重启服务器： 14 reboot
