Set up VBox Bridge network interface on Ubuntu

To establish a permanent "host interface" on the http://www.aliyun.com/zixun/aggregation/13835.html ">ubuntu host", perform the following steps:

1. First install the Bridging program (bridge-utils). You can execute the following command, and the code is:

sudo apt install bridge-utils

2. Then you have to modify the contents of the file/etc/network/interfaces, the following is a simple example, to create a bridge called Br0, and add eth0 to it, use DHCP to obtain the IP address.

Auto br0 iface br0 inet DHCP bridge_ports eth0

You can make the appropriate changes as needed, and you can also assign it a net state address. For examples and resolutions, refer to the following file: a/usr/share/doc/bridge-utilities/readme. Debian.gz and B)/usr/share/doc/ifupdown/examples/network-interfaces.gz.

3. Restart networking on host, the code is:

sudo/etc/init.d/networking restart

Each time you start your host system, this bridge will automatically be generated again.

4. In order to produce a permanent name vbox0 (which must be called VBox, followed by a number) and added to the resulting bridge network, use code:

sudo vboxaddif vbox0 <user> br0 # Use your name to replace <user>

To tell VirtualBox to use this interface, choose to fold a virtual machine, configure the network card as: Checkmark to:host Interface Host Interface Settings Interface name:vbox0

This kind of bridge network card is OK.
