Okay I got it!

container version is slightly different from awx-rpm. All happen in awx_web container. You must use persistent volume so as to use venv and project data over ephemeral container.

You must use python 3 with ansible 2.9.x

cd installer && vi inventory

custom_venv_dir=/opt/my-envs
project_data_dir=/var/lib/awx/projects

you can run installer

ansible-playbook -i inventory install.yml

check mounts

docker inspect -f "{{ .Mounts }}" awx_web
[{bind /opt/my-envs /opt/my-envs rw true rprivate} {bind /var/lib/awx/projects /var/lib/awx/projects rw true rprivate}]

Right from now, you modify the container itself, becareful data are not persistent along container lifecycle, so what follows is for POC. You should build your own container image with this wanted parameters.

yum install -y make gcc redhat-rpm-config python3-devel libcurl-devel libxml2-devel
source /opt/my-envs/py36/bin/activate
pip install psutil
export PYCURL_SSL_LIBRARY=openssl; pip install pycurl --compile --no-cache-dir
pip install ansible ovirt-engine-sdk-python centreonapi dnspython

select the py36 venv into the source to sync and it should work

Objet: Re: [ovirt-users] Re: AWX and error using ovirt as an inventory source

Actually it seems I was using the wrong container... so explaining why I got the not found error about /opt/my-envs/ovirt/lib ... ;-)

I was working on ansible/awx_web:9.0.1 container, while it seems I have to work ansible/awx_task:9.0.1

After doing same steps on this container I get now this kind of error at the end while using apparently the correct virtualenv:
