Depending on your configuration, it might display designed to cooperate. For example, one virtual machine may contain a web server and a second one a database, and since they are intended to talk to each other, the appliance can instruct VirtualBox to set the web server to the outside world to serve data to, but the outside world cannot connect to the database. To change a virtual machine’s virtual network interface to “host only” mode: 103 6 Virtual networking
