The environment executing the test playbooks matters. Establish a
script to bootstrap a known-good and fixed-version python virtual
environment. Spell out precise execution requirements in a standard
pip 'requirements.txt' file, including version numbers and hashes.
Upon executing the ``venv-ansible-playbook.sh`` wrapper, a virtual
environment is setup and contained within a fixed (or temporary)
directory, with full logs from setup. If this is to be preserved
across executions, the ``$WORKSPACE`` environment variable must be
set and exported beforehand.

Without any swap space enabled, it's possible some intensive operation
can chew up all the memory on the test VM. Enabling swap space will
prevent this for minor cases, but could lead to disk-thrashing if the
memory demand is excessive.
Since the test system never reboots, using a file-backed swap should
suffice. Though not ideal, it's easy to setup and doesn't require any
interactions with the cloud that owns the VM or the job that created it.
