I am getting a fatal error in lxc_create when running openstack-ansible
playbooks/setup-hosts.yml and hoping someone can push me in the right
direction. Logs below...
I am interpreting the fatal error as some sort of missing config, which
is why I included the warnings that happened earlier in the above. Is
that right? Is there any way I can isolate where exactly in the ansible
setup this happens?
The only significant changes I've made to the ansible setup are
- comment out `linux-image-extra-{{ ansible_kernel }}` package from the
ubuntu config as it no longer exists.
- create /etc/ansible/.../*ubuntu-18.04.yml files by copying the
equivalent ubuntu-16.04.yml file, where no 18.04 version was already
present.

Context: I want to run openstack on ubuntu bionic, and using ansible
seemed to be the best way forward. I know openstack-ansible is only
supported on xenial, but as I'm a software developer I thought I'd give
it a go. I first commented out the OS checks... and have got a good deal
of progress since. However, I have hit a problem and am hoping someone
can help.
I also posted this question on the ask.openstack pages but it's still
awaiting moderation :(
