经验 Oracle VM VirtualBox 配置虚拟网卡实现桥接上网

Step1:
VirtualBox在虚拟机关机状态下，选中需要配置的虚拟主机，点击选择“设置”，选择“网络”，选择一个你想使用的网卡，勾选“启用网络连接”，连接方式选择“桥接网卡”。

Step 2:

虚拟机开机，打开/etc/udev/rules.d/70-persistent-net.rules内容如下面例子所示：

# vi /etc/udev/rules.d/70-persistent-net.rules
# This file was automatically generated by the /lib/udev/write_net_rules
# program, run by the persistent-net-generator.rules rules file.
#
# You can modify it, as long as you keep each rule on a single
# line, and change only the value of the NAME= key.
# PCI device 0x1022:0x2000 (pcnet32)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:8f:89:9
7", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"
# PCI device 0x1022:0x2000 (pcnet32)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:50:bd:1
7", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"

记录下，eth1网卡的mac地址00:0c:29:50:bd:17

接下来，打开/etc/sysconfig/network-scripts/ifcfg-eth0

# vi /etc/sysconfig/network-scripts/ifcfg-eth0

将 DEVICE="eth0" 改成 DEVICE="eth1" ,
将 HWADDR="00:0c:29:8f:89:97" 改成上面的mac地址 HWADDR="00:0c:29:50:bd:17"

最后，重启网络

# service network restart
或者

# /etc/init.d/network restart

这样就可以了。
可以使用ifconfig查看本机是否为独立IP，如果是那就是已经成功了。
