Open Stack

Hi All,
I tried to install openstack kolla by following kolla documentation:
https://docs.openstack.org/kolla-ansible/latest/user/quickstart.html

When doing this command: "kolla-ansible -i ./multinode bootstrap-servers",
I observed following error:
Error message is "fatal: [control01]: FAILED! => {"msg": "The task includes
an option with an undefined variable. The error was: 'dict object' has no
attribute 'ipv4'\n\nThe error appears to have been in
'/usr/local/share/kolla-ansible/ansible/roles/baremetal/tasks/pre-install.yml':
line 19, column 3, but may\nbe elsewhere in the file depending on the exact
syntax problem.\n\nThe offending line appears to be:\n\n\n- name: Generate
/etc/hosts for all of the nodes\n  ^ here\n"}
Command failed ansible-playbook -i ./multinode -e @/etc/kolla/globals.yml
-e @/etc/kolla/passwords.yml -e CONFIG_DIR=/etc/kolla  -e
action=bootstrap-servers
/usr/local/share/kolla-ansible/ansible/kolla-host.yml

any suggestion?
