Summary:
I believe the failures in the Server DVD chained Base tests are
happening because the VM is not cleanly shut down before the disk
image is uploaded. This adds a shutdown step to all tests that
upload a disk image (so, for now, just default_install). To keep
things simple it just runs 'shutdown' from a root console, rather
than using graphical desktop shutdown methods, as the aim is only
to make the disk state clean, not to test shutdown exactly.
I've tested this on staging; a Server DVD test run with this
change produced a full set of passed tests, as opposed to all
the Base tests failing because the system didn't boot properly.
Workstation and KDE tests seem to work fine also.
For the record, SUSE does much the same thing as this commit.
Test Plan:
Do a full test run and make sure everything that worked
before still does. Check that all default_install tests have a
_console_shutdown step added, and it works, and all chained tests
work (or fail for some unrelated reason, but make sure this
doesn't break them).
