I've kicked off an adhoc test (hopefully correctly) of v3.14 using the
template failure from flight 31795. It's easiest to do this in the
Cambridge instance because that has the oldest (and therefore nearest
the actual bug) flight.

I had to bodge it slightly by changing the freebsd_image to a raw one
since the templates used a qcow2 but the current harness seems to no
longer support that.

Assuming this flight produces something useful (i.e. a pass) then I'll
look into a bisect.

Ian.
