Setting up VirtualBox Bridged Network on Windows 7 Host

Ubuntu 9

VirtualBox is a powerful, open-source, cross-platform virtualization software that allows you to create and manage virtual machines (VMs) on your computer. One of the key features of VirtualBox is its networking capabilities, which can be configured in a variety of ways to suit your needs. In this article, we will focus on setting up a Bridged Network on a Windows 7 host.

Quick Answer

To set up a VirtualBox Bridged Network on a Windows 7 host, open VirtualBox, select the VM, access the VM settings, navigate to network settings, configure the Bridged Adapter, and save the changes. If you’re having trouble SSHing into your Ubuntu guest machine, check firewall settings, verify SSH daemon status, enable VirtualBox Bridged Networking Driver, and check VirtualBox modules.

What is a Bridged Network?

In VirtualBox, a Bridged Network allows a virtual machine to connect to a network using the host computer’s Ethernet adapter. This means that the VM appears to other machines on the network as a physical device, with its own IP address and network identity.

Setting up VirtualBox Bridged Network

Step 1: Open VirtualBox and Select the VM

Launch VirtualBox and select the virtual machine for which you want to set up a bridged network.

Step 2: Access VM Settings

Navigate to the “Settings” of the selected virtual machine. You can find this option in the toolbar at the top of the VirtualBox Manager window.

Step 3: Navigate to Network Settings

In the Settings window, click on the “Network” tab on the left panel. This will open the network settings for your virtual machine.

Step 4: Configure Bridged Adapter

Under the “Adapter 1” tab, ensure that the “Enable Network Adapter” checkbox is ticked. In the “Attached to:” dropdown menu, select “Bridged Adapter”. This will allow your VM to connect to your physical network.

In the “Name” dropdown menu, select the network adapter that is connected to your Local Area Network (LAN). This is typically the Ethernet or Wi-Fi adapter of your host machine.

Step 5: Save Changes

Click “OK” to save your changes and close the Settings window.

Troubleshooting: SSH into Ubuntu Guest

If you’re having trouble SSHing into your Ubuntu guest machine, follow these troubleshooting steps:

Step 1: Check Firewall Settings

On your Windows 7 host machine, ensure that port 22 (the default port for SSH) is open. This can be done through the Windows Firewall settings.

Step 2: Verify SSH Daemon Status

On your Ubuntu guest machine, verify that the SSH daemon (sshd) is running. This can be done by running the command sudo service ssh status in the terminal. The sudo command gives you administrative permissions, service is used to run a System V init script, ssh is the service you’re checking, and status displays the current status of the service.

Step 3: Enable VirtualBox Bridged Networking Driver

On your Windows 7 host machine, ensure that the VirtualBox Bridged Networking Driver is enabled for the “VirtualBox Host-Only Network” connection. This can be done through the Network and Sharing Center.

Step 4: Check VirtualBox Modules

On your host machine, confirm that the vboxdrv and vboxnetflt modules are running. This can be done by running the command lsmod | grep vbox in a terminal. The lsmod command shows the status of modules in the Linux Kernel, grep is a command-line utility for searching plain-text data, and vbox is the term you’re searching for.

By following these steps, you should be able to set up a VirtualBox Bridged Network on a Windows 7 host and successfully SSH into your Ubuntu guest machine. If you encounter any issues, refer to the VirtualBox User Manual for further guidance.

What is the purpose of a Bridged Network in VirtualBox?

A Bridged Network in VirtualBox allows a virtual machine to connect to a network using the host computer’s Ethernet adapter, appearing as a physical device with its own IP address and network identity.
