You will likely need to use the internet to gather some information. To reconfigure the network interface run sosetup-network and reboot. The management interface is enp0s3 and the monitor interface is enp0s8. Use DHCP to get an address from the NAT Server on VirtualBox. Ignore the message on the SO Screen to run setup again.
