Using Unicamp's Minicloud for the QEMU CI

Using Unicamp's Minicloud for the QEMU CI

Hi everyone!

I would like gauge the interest in using Minicloud's infrastructure[1] 
for the CI, talking with some people from there they are interested. It 
has both ppc64 and pp64le images, multiple versions of 4 distros 
(Ubuntu, Fedora, Debian and CentOS).

I've made a initial test setup in a fork[2] with a branch(ppc64-runners) 
that has both a new pipeline with jobs to run on the ppc64/ppc64le 
runners and updated some scripts (mainly the build-environment.yml) to 
automate the setup of the environment in those architectures.

PPC host is something we're currently missing in our testing, so definitely
yes in principle. I don't know what the specifics of getting new runners
set up is, though. Alex ?

thanks

So the first thing is can we have a minicloud VM dedicated to CI 24/7?
Our current usage of the GitLab CI model relies on the runner always
running on the host rather than being spun up on demand.

After that you need to extend:

  scripts/ci/setup/build-environment.yml
  scripts/ci/setup/gitlab-runner.yml

to setup a ppc64 host and setup the gitlab runner on it. We document
this at:

  https://qemu.readthedocs.io/en/latest/devel/ci.html#machine-setup-howto

After that we can define a new variable in the GitLab config
(PPC64_RUNNER_AVAILABLE) and then define some custom build jobs in:

  .gitlab-ci.d/custom-runners/

to run the build and test on the native ppc64 HW.

It looks like your branch has most of this stuff already but I couldn't
see any successful runs. I think this is tripped up by our switch to not
trigger CI by default. See the documentation about QEMU_CI:

  https://qemu.readthedocs.io/en/latest/devel/ci.html#setting-aliases-in-your-git-config
