I have been working on getting a helm distribution running on a vm for some time. I have found conflicting arguments about it being possible or not due to virtualization layers, but here it goes.
I am working with a virtualbox ubuntu 16.04 with 16gb ram following the guide at https://docs.openstack.org/openstack-helm/latest/install/developer/requirements-and-host-config.html
I am also working behind a proxy and I have added all the relevant proxy settings in accordance with https://docs.openstack.org/openstack-helm/latest/troubleshooting/proxy.html
When I run the command make dev-deploy setup-host it passes and has the following output:
$ docker ps

I have the same error. Problem is simple: your hostname doesn't match to this one that Ansible want to run a job.
E.g.:
root@k8s1:~# hostname
k8s1
So in /etc/hosts, it add:
XXX.XXX.XXX.XXX k8s1.XXX.test k8s1Solution:
echo "k8s1.XXX.test" > /etc/hostname
hostname "k8s1.XXX.test"
reboot
I had the same issue in this step of the Ansible playbook when deploying an AIO openstack with Helm on a VM.
In this step a number of docker containers are created. (You can verify this with "docker ps" in another terminal. It takes some time)

I'm not 100% sure but it could be a resource issue. Maybe the containers aren't created fast enough on your VM and therefore the script returns these failures:
"FAILED - RETRYING: wait for node to come online (1 retries left).",
As you can see in my output, I have more containers running.
Working VM specs:
