"""
Example script - needs configuration (or use lava-tool).
Expects to submit a pipeline job to a QEMU device, so
ensure that the host supports these jobs.
**This script is not to be expanded with argparse or CLI options for
the username, token, hostname or image**.
It is meant to be copied into something like jenkins to do the
submission using hardcoded values, themselves hidden behind a UI.
Other details like architecture, prompt and login information may
need to come from a config file or command line.
LAVA needs a serial console to tell whether the VM booted or not.
Larger images will need the LAVA device to have more memory available.
