An Alternative Method for Adding More Nodes to the Network
Another way you can add a VM to one or more of the internal virtual networks in VirtualBox is by cloning the VM. However, keep the following in mind:
- To quickly set up any configurations that you want across multiple nodes on your system, configure the settings on the original VM, then clone the VM using Machine > Clone. For example, if you want to include a management VM for the new topology you are going to create, you can set the eth0 port to be on a virtual network that the management VM is on, so when you clone the new VM, it will duplicate this port, giving you an out-of-band (OOB) network.
- When you clone the VM, you save on disk storage by referring to the original disk image instead of copying it to the new VM.
- Always reset your MAC addresses on the virtual NICs, unless you have a strong reason not to do so.
