[RFC XEN PATCH 00/13] Running bare-metal tests with "pytest"

[Anthony PERARD <anthony@xenproject.org>]

From: Anthony PERARD <anthony.perard@vates.tech>

Hi,

I wanted to add some new machine to our GitLab CI, but I didn't want to
duplicate yet another time the existing shell script. They are good to get the
ball rolling but are getting harder to maintain as more test are been added,
and don't share common code between machines.

So, I've start work on something based on `pytest` which I hope will be easier
to maintain and extend and use to add new machines.

It's still Work In Progress.

Here is the current result:
    https://gitlab.com/xen-project/people/anthonyper/xen/-/jobs/16529107619

In this pipeline, the artifact use are a bit different from master; linux is
built with network driver, and vlan; the rootfs is from Marek's patch series,
with networking and dropbear service enabled.

Next:

I'd like to at least have a new fixture that give a started Host that a test
can ssh into. Then maybe a new class "Host" which could have functions for ssh
and getting the serial console output.

Don't go to much into detail review, I'm more interested of a general overview,
and to present what I have so far.

Some runes:
    - uv run mypy .
      to check the code, at least the types used.
      other code check could be added, and run by the pipeline
    - uv run pytest
      to run the whole test suite
    - uv run pytest test_boot.py::test_xen_tools_tests
      to run just one test

I did create an Arch Linux docker image with pytest, but paramiko got too new
to be used, so I've started to use `uv` to deal with the dependencies. `mypy`
always needed to be run with `uv` due to missing types for paramiko (not
packaged in Arch Linux). So the image is useless, and I'll look for a different
image later, for now just Arch Linux with `uv` installed.

Thanks,
