Opensuse virtualbox network setup

Do I need a bridge? How can I configure such? Thanks for any help! Re: VirtualBox network setup Maybe this will help. It's for openSUSE The PDF of the manual is at virtualbox. In Novell was acquired by Attachmate. The openSuSE project offers two distributions: Tumbleweed , which is a rolling distribution that gets continuous updates, and Leap , which is a point distribution that gets periodic updates.

According to me, you should download Leap version to obtain a better stability. OK, now I will download this version. Select RAM capacity that you provide to this virtual machine.

If there is a DHCP server in your physical network, the virtual network adapter of the VM will obtain the IP address automatically in the bridged mode if obtaining an IP address automatically is set in the network interface settings in a guest OS. Thus, the default gateway for a virtual network adapter operating in the bridged mode is the same as for your host machine.

IP configuration of the host machine: The IP address — IP configuration of the guest machine: The IP address — Sometimes, you may find that you have multiple gateways in your physical network. You can use a host machine for connecting to necessary networks via one gateway and use a guest machine for connecting to other networks via the second gateway. You can also edit a routing table on your VM and add routes for using both gateways to connect to the appropriate networks.

As you can see, the bridged network mode is a powerful option in VirtualBox network settings with a lot of use cases. Promiscuous mode. This mode allows a network adapter to pass all received traffic, no matter to which adapter the traffic is addressed. In normal mode, a network adapter receives only frames that include the MAC address of this particular network adapter as the destination address in the header. The frames that are addressed to a MAC address which differs from the MAC address of the selected adapter when traffic is not broadcast are dropped when in normal mode.

The promiscuous mode makes it possible for a physical network adapter to have multiple MAC addresses, allowing all incoming traffic to pass the physical network adapter of the host machine and reach the virtual network adapter of the VM which has its own MAC address that is represented on the host adapter, even if that traffic is not addressed to the virtual network adapter of that particular VM.

Bridging to Wi-Fi adapters is done in following way — VirtualBox replaces the appropriate MAC addresses in the headers of Ethernet frames that must be delivered to the virtual network adapter of the VM the MAC address of the host Wi-Fi adapter must be used for that traffic. The promiscuous mode is useful for network testing and security audits.

You can enable the promiscuous mode in VirtualBox network settings and monitor network traffic with a sniffer. Virtual machines whose adapters are configured to work in the VirtualBox Internal Network mode are connected to an isolated virtual network. VMs connected to this network can communicate with each other, but they cannot communicate with a VirtualBox host machine, or with any other hosts in a physical network or in external networks.

VMs connected to the internal network cannot be accessed from a host or any other devices. The VirtualBox internal network can be used for modelling real networks. For example, you can create three VMs, each of which has a virtual network adapter Adapter 1 connected to the internal network. The IP addresses of these network adapters are defined from the subnet used for the VirtualBox internal network you should define the subnet manually.

IP address — This network mode is used for communicating between a host and guests. A VM can communicate with other VMs connected to the host-only network, and with the host machine. The VirtualBox host machine can access all VMs connected to the host-only network. The VirtualBox Host-Only virtual network adapter is created in a host operating system for use in the host-only network. In our case, the default network address of the host-only network is You can edit these IP addresses manually in the Adapter tab.

A DHCP server can be enabled or disabled by ticking the appropriate checkbox. It is also possible to create more than one VirtualBox host-only network adapter in order to use different host-only networks—just press the Create button. Next, refresh the repository list using the following zypper command. Once the repositories have been refreshed, you will need to install few required packages for building VirtualBox kernel modules and header files using the following command.

You can download the VirtualBox Extension Pack using the following wget command. After selecting the extension package file, read the message from the dialog box and click on Install as shown in the following screenshot.

Then read the use and evaluation License and click I Agree to start the actual installation. You will be prompted to enter your root user password, provide it to proceed. Once the installation is complete, the extension package installed should be listed under Extensions. You can ask questions or share your thoughts about this article via the feedback form below.
