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：
[root@master init.d]# ./network restart正在关闭接口 ens33： 错误 : [/etc/sysconfig/network-scripts/ifdown-eth] 设备 具有 MAC 地址 00:00:00:00:00:0000:0C:29:94:8E:A2，而不是配置的地址 00:0C:29:8B:9A:F2。忽略。 [失败]正在关闭环回接口： Could not load file '/etc/sysconfig/network-scripts/ifcfg-lo'Could not load file '/etc/sysconfig/network-scripts/ifcfg-lo'Could not load file '/etc/sysconfig/network-scripts/ifcfg-lo'Could not load file '/etc/sysconfig/network-scripts/ifcfg-lo' [ 确定 ]正在打开环回接口： Could not load file '/etc/sysconfig/network-scripts/ifcfg-lo'Could not load file '/etc/sysconfig/network-scripts/ifcfg-lo'Could not load file '/etc/sysconfig/network-scripts/ifcfg-lo'Could not load file '/etc/sysconfig/network-scripts/ifcfg-lo' [ 确定 ]正在打开接口 ens33： 错误：没有找到可用于连接 'ens33' 的设备。 [失败]
3、执行 systemctl restart network报错：
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：
ens33: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet 192.168.130.109 netmask 255.255.255.0 broadcast 192.168.130.255 inet6 fe80::20c:29ff:fe94:8ea2 prefixlen 64 scopeid 0x20<link> ether 00:0c:29:94:8e:a2 txqueuelen 1000 (Ethernet) RX packets 550 bytes 48524 (47.3 KiB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 604 bytes 94343 (92.1 KiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0lo: flags=73<UP,LOOPBACK,RUNNING> mtu 65536 inet 127.0.0.1 netmask 255.0.0.0 inet6 ::1 prefixlen 128 scopeid 0x10<host> loop txqueuelen 0 (Local Loopback) RX packets 8 bytes 800 (800.0 B) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 8 bytes 800 (800.0 B) 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
TYPE="Ethernet"DEFROUTE="yes"IPV4_FAILURE_FATAL="no"NAME="ens33"UUID="707084bc-d3aa-483f-878b-c93e6abf4a07"ONBOOT="yes"HWADDR="00:0C:29:8B:9A:F2"BOOTPROTO="static"NM_CONTROLLED="yes"IPADDR="192.168.130.101"NETMASK="255.255.255.0"GATEWAY="192.168.130.2"
将HWADDR改为00:0c:29:94:8e:a2即可。
