如何在復制VM和VBOX虛擬機時重新配置網卡

如何在復制VM和VBOX虛擬機時重新配置網卡？這個問題可能是我們日常學習或工作經常見到的。通過這個問題，希望你能收獲更多。今天跟隨小編一起來看解決方案吧。

1、 新復制的虛擬機，請選擇重新生成MAC地址，這個步驟在復制（克隆，WHATEVER）的時候，或者在復制完成，又或者完成后點配置，網卡屬性，高級屬性（各種平臺各不相同，找到重新生成MAC地址，勾上或者刷新）。記錄下這個MAC地址
2、新虛擬機啟動以后，無論網絡是否正常，停掉NetworkManager.Service...真的沒有那么好用。
systemctl stop NetworkManager
systemctl disable NetworkManager
3、運行ifconfig -a, 得到新網卡的網卡名稱，（也是設備名稱，結合剛才記錄下的MAC地址，很容易對上）
4、到/etc/sysconfig/network-scripts文件夾修改ifcfg-enxxx網卡啟動配置文件
4.1、 強烈建議刪除ifcfg-profile1類似這個腳本，這個是NetManager遺留。
4.2、 用uuidgen  enxxx這樣的格式得到uuid寫入配置檔。
4.3、 寫完配置檔，重啟網卡設備systemctl restart network。如果沒有報錯就完成了。

####舉例：
###配置一個網卡最終要三個要素，設備名，MAC地址，UUID

eno16777736: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 192.168.1.201  netmask 255.255.255.0  broadcast 192.168.1.255
        inet6 fe80::20c:29ff:fe4a:b12c  prefixlen 64  scopeid 0x20<link>
        ether 00:0c:29:4a:b1:2c  txqueuelen 1000  (Ethernet)
        RX packets 3647  bytes 3417904 (3.2 MiB)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 142  bytes 18249 (17.8 KiB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

eno33554992: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 192.168.199.241  netmask 255.255.255.0  broadcast 192.168.199.255
        inet6 fe80::20c:29ff:fe4a:b136  prefixlen 64  scopeid 0x20<link>
        ether 00:0c:29:4a:b1:36  txqueuelen 1000  (Ethernet)
        RX packets 5605  bytes 3465915 (3.3 MiB)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 1400  bytes 322360 (314.8 KiB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

###uuidgen （注意，UUID每次生成都不同，但是每個生成的ID都是可以用的）

[root@mysql01 dev]# uuidgen eno16777736
fd32246b-c655-45c6-ab6a-7a6aa84faa72
[root@mysql01 network-scripts]# uuidgen eno33554992
44e70d2f-4bf1-4753-865b-8fb042ecc8d6

###停止NetworkManager

[root@mysql01 network-scripts]# systemctl stop NetworkManager
[root@mysql01 network-scripts]# systemctl disable NetworkManager
Removed symlink /etc/systemd/system/multi-user.target.wants/NetworkManager.service.
Removed symlink /etc/systemd/system/dbus-org.freedesktop.NetworkManager.service.
Removed symlink /etc/systemd/system/dbus-org.freedesktop.nm-dispatcher.service.

[root@mysql01 network-scripts]# systemctl status NetworkManager

[root@mysql01 network-scripts]# ifconfig

###寫配置檔：（這里的UUID可能和我上面獲得的不同,因為配置檔是之前就寫好的.）

###重啟網絡服務:

[root@mysql01 network-scripts]# systemctl restart network.service
[root@mysql01 network-scripts]# 

###沒有報錯
