Recommendation For Reinitialize The Mac Address Of All Network Cards When Making A Virtualbox Clone4/28/2021
The routers each use three of the four available network adapters to connect to internal networks.In addition to creating and managing individual virtual machines, VirtualBox can connect virtual machines together to emulate a network of computers and network appliances such as routers or servers.
VirtualBox works on the major computing platforms: Windows, MacOS, and Linux. This tutorial will utilize some of the advanced functions supported by VirtualBox and provide you with the skills to set up a network of virtual machines on your own personal computer. I also assume you have a basic understanding of Linux shell commands, which will be needed to configure the Linux operating system running on the virtual routers and PCs. VirtualBox does not have a drag-and-drop graphical user interface for creating networks of virtual machines so you must draw the network using another tool such as Microsoft PowerPoint, Visio, or open-source alternatives like LibreOffice Draw or Dia or even pencil and paper. Once the network topology and IP network design is defined, build configuration plans (see the tables I use later in this post) and set up and debug the emulated network. The network topology you will create is shown in the figure below. I added a network adapter on each guest VM and attached it to the VirtualBox NAT interface to connect each guest VM to the host computer and to other external networks. Your personal computer is connected to a local area network and to the Internet via a router. Recommendation For Reinitialize The Address Of All Network Cards When Making A Virtualbox Clone Install A VMIf you need to know how to install a VM in VirtualBox, please see my post about installing a Linux system in a VirtualBox VM. See below that a virtual machine named Ubuntu server appears in the VirtualBox Manager window. If you chose a different hostname, you will need to modify some of the commands I list later in this tutorial. Right-click on Ubuntu server and select Clone from the menu. You must ensure that the MAC addresses will be different on each cloned VM. In this case, create a total of six virtual machines, each of which is a linked clone of the Ubuntu server VM. Choose virtual machine names to match the node names defined in the network diagram. This limits the complexity of network scenarios you can create. Fortunately, VirtualBox really supports up to thirty-six network adapters per VM. These additional network adapters may be configured using the VirtualBox command-line interface, which is a topic for another post. For now, limit yourself to using the four adapters supported on each VM by the VirtualBox GUI. If enabled, the adapter may be configured to connect to one of the many different types of interfaces provided by VirtualBox. In the example below, you will configure Network Adapter 2 on the Router-1 virtual machine. The name must match with the name configured on the corresponding network adapter on other the VM to be connected to this VM.
