For starters, they'll need to be different addresses that also don't
clash with anything else on your network.

With VirtualBox, I find that it works well for me if I use the "Bridged"
network setting, which allows your virtual machine to connect to your
physical LAN. AFAICT the NAT setting appears to set up a virtual LAN
inside the VM which most probably isn't what you want.

BTW why are you using Ubuntu 12.04? Why not use the LTS 14.04 version?
Fixing the IP address in the /etc/network/interfaces file is easy:-

# The primary network interface
auto em1
#iface em1 inet dhcp
#Changes to:-
iface em1 inet static
  address          192.168.2.2
  netmask          255.255.255.0
  network          192.168.2.0
  broadcast        192.168.2.255
  gateway          192.168.2.1
  dns-nameservers  192.168.2.1 8.8.8.8

This is what is in my 14.04 home server.
