Bug Description
Tester did not have a local cloud image copy, and did not specify one in the config file. When the virtualization test ran, the results were tracebacks and unhandled exception errors:

This is probably caused by connection wonkiness; the script is trying to download a cloudimage but running into a timeout:
urllib.
The root cause of this is the connection trouble; I suggest the user try to download the given URL manually to diagnose things:

Of course, the traces are ugly and make users unhappy :( in our code, the problem is that we're not catching the URLError exception that urlretrieve can raise. We can add that exception to the list in line 85 of the script to at least result in a friendly error message and clean failure, rather than end-of-the-world as it is now.
