As the firewalld tests expect the libvirt "default" network, add
cockpit-machines test dependency, which pulls in the libvirt stack. We
will soon test the Machines page anyway.
Upstream now grows more and more @nondestructive test, which we can run
in our single test VM, so add the first batch.
This uncovers some issues in the tests that assume that there is no root
login in the VM, skip them. They are being fixed in
https://github.com/cockpit-project/cockpit/pull/13773
check-menu is a very robust test that also does not change the host too
much. This does not cover a lot of functionality to actually find
regressions in subsystems, but exposes the missing pieces for
running more integration tests in the dist-git pipeline.
Re-use the cockpit/tests container for this, which has the necessary
test dependencies -- most importantly, chromium-browser. Aside from not
being available in RHEL, this also better shields the tests from the
tested system. The container talks to Cockpit on the host, i. e. the
container's gateway.
Use a fixed tag to avoid running into failures with "latest", as we
don't gate container updates on the dist-git tests for now.
