VMware克隆後找不到eth0

用ESX克隆虛擬機的時候，會發現網卡編號變化了，原來的eth0,eth1不見了，而出現了eth2,eth3。我估計可能的原因是ESX在創建虛擬機時，會重新創建網卡，當系統發現網卡和配置不一樣時，就新建了新的網絡接口。

可以用下面的方法把eth0改回來：

修改70-persistent-net.rules文件

1. [root@RedHat89178 ~]# cat /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. #
   
5. # You can modify it, as long as you keep each rule on a single
   
6. # line, and change only the value of the NAME= key.
   
7. 
   
8. # PCI device 0x15ad:0x07b0 (vmxnet3)
   
9. # 把原來的配置注釋掉
10. #SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:50:56:9c:00:99", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"
    
11. 
    
12. # PCI device 0x15ad:0x07b0 (vmxnet3)
13. # 把新出現的eth2改為eth0
14. SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:50:56:9c:00:9a", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"

更改網卡配置文件

1. [root@redhat89178 ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0
   
2. DEVICE="eth0"
   
3. BOOTPROTO=static
4. # 把MAC地址改成新的地址
   
5. HWADDR="00:50:56:9C:00:3A"
6. ...

更新主機名

1. [root@redhat89178 ~]# cat /etc/sysconfig/network
   
2. NETWORKING=yes
   
3. HOSTNAME=<new_hostname>
   
4. GATEWAY=10.10.10.1
