Potentially?

Suppose we fired up a guest OS and captured the console output.  Is there
a way to make that guest OS shut down automatically at the end of the
test and to extract the test results?

In the short term, I am good with this the current state of this being
default-disabled and those of us wishing to run it regularly adjusting
our scripts accordingly.

But, longer term, if there is a better way...
