Assuming I have two host machines in the same LAN running ubuntu, and on each one I set up two guest virtual machines also running ubuntu. The virtualization software, in this particular case is Virtual Box.
I'd like to create a private LAN with all VMs (even so they're in different hosts). Today I'm using only 2 guests in the same host, and connect them by setting up the bridge mode.
How can I connect all 4 VMs using my lan connection? (The hosts are in the same LAN, but they don't have internet access).
