Virtual Machine Setup
Note: There are several other webpages describing how to install a new VM on different web systems. A good example on how to install Ubuntu on a MAC is here.
After your VM restarts, you can log in using the username and password you supplied during installation. To launch applications, you can use the menu in the top-left corner. Find the Terminal Emulator application – you will be using this a lot!
VM snapshots are a simple way to save the state of your VM before experimenting with it. To save a snapshot, go to the VM menu, then Snapshot, and choose "Take Snapshot." Take a snapshot right now in case you ever need to reset to a freshly installed system.
You can always revert to a saved snapshot if something goes awry, so feel free to use them liberally. Note that reverting to a snapshot will reset the contents of the virtual disk too, so be sure to have a backup copy of your code somewhere non-virtual!
