# Basic initial configuration of Ubuntu 12.04 on VirtualBox
# (execute after installing the relevant ISO on the VM through VirtualBox: http://releases.ubuntu.com/12.04/)
# 
#
# In order to access the VM from your host (e.g. OS X), forward the relevant ports on VirtualBox:
# Network -> Adapter 1 (NAT) -> Port Forwarding (http://stackoverflow.com/a/10532299/2708484)
#
# Easily access the VM by adding the following to your host's ~/.ssh/config
# (allows for `ssh $VM_HOST` as opposed to `ssh -p $VM_PORT $VM_USER@127.0.0.1`):
#
# host $VM_HOST
#	HostName 127.0.0.1
#	Port $VM_PORT
#	User $VM_USER
