Comment 6 for bug 1906566

From my understanding of the docs, kolla-asible should create the virtual environment:

> Kolla-ansible provides support for creating a python virtual environment on the target hosts as part of the bootstrap-servers command. The path to the virtualenv is configured via the virtualenv variable, and access to site-packages is controlled via virtualenv_site_packages.

https://docs.openstack.org/kolla-ansible/latest/user/virtual-environments.html#target-hosts

I've added this to the top of /etc/kolla/globals.yml:

virtualenv_site_packages: yes
virtualenv: /root/targethost/env
ansible_python_interpreter: /root/targethost/env/bin/python

And I get:

# kolla-ansible -i ./all-in-one bootstrap-serverss
Bootstrapping servers : ansible-playbook -i ./all-in-one -e @/etc/kolla/globals.yml -e @/etc/kolla/passwords.yml -e CONFIG_DIR=/etc/kolla -e kolla_action=bootstrap-servers /root/kolla/env/share/kolla-ansible/ansible/kolla-host.yml

I can update the docs and even try to fix the code. But I'd need to know if I'm doing something wrong or this is a bug.
