Linux的虚拟机拷贝到另外的操作系统时，NAT方式的静态IP无效，一直是获取的DHCP动态地址

浏览数：45 / 时间：2015年06月20日
一、问题：
1、Linux虚拟机在A机的虚拟机中是NAT方式DHCP动态获取IP，设置了静态地址，IP地址不会发生变化，但是拷贝到B机上的虚拟机后，一直获取的时动态IP地址，无法得到静态IP。
2、执行/etc/init.d/network restart报错：
  1. [root@master init.d]# ./network restart
  2. 正在关闭接口 ens33： 错误   : [/etc/sysconfig/network-scripts/ifdown-eth] 设备  具有 MAC 地址 00:00:00:00:00:00
  3. 00:0C:29:94:8E:A2，而不是配置的地址 00:0C:29:8B:9A:F2。忽略。
  4.                                                            [失败]

3、执行 systemctl restart network报错：
  1. Job for network.service failed. See "systemctl status network.service" and "journalctl -xe" for details.
4、执行journalctl -xe报错：

二、解决：
Linux虚拟机从A拷贝到B后，MAC地址发生改变，但是配置文件中并没有同步修改，导致此问题。
1、首先执行ifconfig查看新的MAC地址：
  1. ens33: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
  2.         inet 192.168.130.109  netmask 255.255.255.0  broadcast 192.168.130.255
  3.         inet6 fe80::20c:29ff:fe94:8ea2  prefixlen 64  scopeid 0x20<link>
  4.         ether 00:0c:29:94:8e:a2  txqueuelen 1000  (Ethernet)
  5.         RX packets 550  bytes 48524 (47.3 KiB)
  6.         RX errors 0  dropped 0  overruns 0  frame 0
  7.         TX packets 604  bytes 94343 (92.1 KiB)
  8.         TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0
  10. lo: flags=73<UP,LOOPBACK,RUNNING>  mtu 65536
  11.         inet 127.0.0.1  netmask 255.0.0.0
  12.         inet6 ::1  prefixlen 128  scopeid 0x10<host>
  13.         loop  txqueuelen 0  (Local Loopback)
  14.         RX packets 8  bytes 800 (800.0 B)
  15.         RX errors 0  dropped 0  overruns 0  frame 0
  16.         TX packets 8  bytes 800 (800.0 B)
  17.         TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0
可以看出ens33网卡对应的MAC地址为：00:0c:29:94:8e:a2，即ether对应的地址。
2、修改ens33网卡对应的MAC地址
vi /etc/sysconfig/network-scripts/ifcfg-ens33
  1. TYPE="Ethernet"
  2. DEFROUTE="yes"
  3. IPV4_FAILURE_FATAL="no"
  4. NAME="ens33"
  5. UUID="707084bc-d3aa-483f-878b-c93e6abf4a07"
  6. ONBOOT="yes"
  7. HWADDR="00:0C:29:8B:9A:F2"
  8. BOOTPROTO="static"
  9. NM_CONTROLLED="yes"
  10. IPADDR="192.168.130.101"
  11. NETMASK="255.255.255.0"
  12. GATEWAY="192.168.130.2"
将HWADDR改为00:0c:29:94:8e:a2即可。
