VBoxManage modifyhd $disk --resize $size

Problems with getting the correct IP adress Edit

It is not uncommon with Virtualbox that you are getting an IP adresse in the 10.0.x.x range, even though your DHCP is on e.g. 172.x.x.x or 192.x.x.x to fix this problem shutdown your virtual machine. Go to settings for the network and change your network card adapter from being PC-NET to being an Intel Pro card. This will solve the problem.
