Save the machine state should have worked.
Afterwards, the VM should stop, and display 'Saved' under the VM name in the 
main VB GUI.
Starting it again should resume it exactly where it was.

What did happen?  What was shown under the machine name?

If a machine crashes (physical or virtual), you can always loose data.
However, if you disable host IO caching, a VM crash will be more exactly like a 
real machine crash, which matters for some
filesystems.

I think you can set this from the GUI now as well.

The VM still has the Ubuntu 'CD' mounted in its virtual CD/DVD drive, so it is 
booting that, just as if you had left an Ubuntu
install CD in a real machine.

Either configure Settings > Storage and set the CD/DVD drive to Empty, or use 
the Devices menu on the VM.
