Open Stack

Hi everyone,
 
I am new to openstack and just followed
the "Quick Start" guide for kolla-ansible
[https://docs.openstack.org/kolla-ansible/ussuri/user/quickstart.html]
on ussuri release, but now having some problems during deployment.
I used virtualbox to create a new vm with ubuntu 18.04.5
[https://releases.ubuntu.com/18.04/ubuntu-18.04.5-live-server-amd64.iso.torrent]
and attached one interface (enp0s3, 10.0.2.15) with Nat-Network and
the second interface as for the neutron interface (enp0s8, no ip)
an internal network and named it "neutron".
Then I followed the guide to create a new virtual python environment
(logged in over ssh using "user" user).
--
sudo apt-get update
sudo apt-get install python3-dev libffi-dev gcc libssl-dev
sudo apt-get install python3-venv

python3 -m venv $(pwd)
source $(pwd)/bin/activate
pip install -U pip
pip install 'ansible<2.10'
--

Everything seems to work as mentioned with no problems so far.
(Beside the missing "python-venv" package in the docs)
--
pip install kolla-ansible
sudo mkdir -p /etc/kolla
sudo chown $USER:$USER /etc/kolla
cp -r $(pwd)/share/kolla-ansible/etc_examples/kolla/* /etc/kolla
cp $(pwd)/share/kolla-ansible/ansible/inventory/* .

mkdir /etc/ansible
sudo nano /etc/ansible/ansible.cfg
### content from /etc/ansible/ansible.cfg
[defaults]
host_key_checking=False
pipelining=True
forks=100
###
--

I then modified the "multinode" file to only deploy on localhost
(replaced all control01, etc. with localhost) as I first wanted
to try openstack on one node.
The ping worked, changed the globals.yml file according to the
documentation, then bootstrap and the prechecks worked
so far with no issue.
--
ansible -i multinode all -m ping
kolla-genpwd

sudo nano /etc/kolla/globals.yml
### additional content of /etc/kolla/globals.yml
kolla_base_distro: "ubuntu"
kolla_install_type: "source"
network_interface: "enp0s3"
neutron_external_interface: "enp0s8"
kolla_internal_vip_address: "10.0.2.10"
###

kolla-ansible -i ./multinode bootstrap-servers
kolla-ansible -i ./multinode prechecks
--

But on the deploy stage I am stuck right now:
--
kolla-ansible -i ./multinode deploy
--

The mentioned error is telling me,
that the keystone service is not available.
I attached the error log file, because the error is longer.
As a side node, now when I try to login using tty,
the vm is nearly frozen and only prompts very, very slowly
(about 10 minutes for prompt). ssh in putty is also frozen
and the connection broke after about 30 minutes.

Does anyone know what is wrong or has some hints/insight on how
to correctly deploy openstack using kolla-ansible?

Best Regards,
Lukas Lüdke
