Why do you need the --userns option?
Because otherwise it's run as a fake root user and will fail on the
tests requiring real root permissions.
You run this in a container because your development environment
is not compatible - right?
Yes, I need to run the tests in a supported and predictable environment.

I never run autogen and make during the tests, this can be done once
after checkout or when modifying the makefiles.
It can but it's safer to run the tests in a clean environment otherwise
they can fail after switching branches or rebases and then one may waste
time on looking at the errors. This part doesn't consume much running
time in comparison with some other parts so why not to have it there.

You are missing:
make storage
Without this, a lot of tests will be skipped or xfailed.
I see. Why does tests-storage not depend on this target? E.g.
.PHONY: tests-storage
tests-storage: tox tests-storage-setup tests-storage-run
.PHONY: tests-storage-run
tests-storage-run:
tox -e "storage"
.PHONY: tests-storage-setup
tests-storage-setup:
python3 tests/storage/userstorage.py setup
But perhaps it is better the way it is because `make storage' requires
root access.

nbd_test.py should be skipped unless you run as root, or have running
supervdsm serving your user.
Not all tests there are marked as requiring root privileges (and they
pass without them).

This is not correct for your local container - in travis we run a
privileged container
as root and we create loop devices before the test.
It is needed to skip tests in common/systemctl_test.py that require
systemd. Perhaps we should use a different mechanism to disable them
there.
Other than that there is no difference between having this variable or
not when running without root privileges.
I tried this:
podman run --rm -it -v `pwd`:/src:Z --userns=keep-id vdsm-test-centos-8
cd src
make tests-storage
Got 2 test failures:

devs = glob.glob("/sys/block/*/dev")

major_minor = f.readline().rstrip()
> assert devicemapper.device_name(major_minor) == dev_name
E AssertionError: assert '7:1' == 'loop1'
E - loop1
E + 7:1
This likey failed since there are no loop devices in the container:
bash-4.4$ ls /dev/
console core fd full mqueue null ptmx pts random shm stderr
stdin stdout tty urandom zero
And there is no way to create them, since your run as regular user
and sudo does not work. Event if it works I think you will not be able
to create the loop devices since the container is not privileged.
It may be possible to map the loop devices from the host to the container
but I never tried.

This fails because we have systemd in the container, but we did not start
the
container in the write way to make it happy.
I'm not sure why the test was not skipped, probably a bug in the skip
condition.
These are the tests where TRAVIS_CI=1 is needed.
But these are not storage tests. Do storage tests pass for you?
I always get the following error:
