A1: When I had the symptoms you are describing it was because the instance
never managed to boot from the image, and was just spinning cpu cycles
displaying a "could not boot disk" type message.  I figured that out by
connecting to the VNC console of the instance.  IIRC, you can look through
the nova logs to figure out what VNC address to hit for the instance.

Apologies to aron, who will see this twice.
