[Openstack] unexpected distribution of compute instances in queens


Hi Smooney,

thank you for your help. I am trying to enable randomization but not
working. The instance I have created is still in the same node. Below is my
nova configuration (added randomization from your suggestion) from the
master node (Template jinja2 based).

[DEFAULT]
enabled_apis = osapi_compute,metadata
transport_url = rabbit://openstack:{{ rabbitmq_pw }}@{{ controller1_ip_man
}}:5672,openstack:{{ rabbitmq_pw }}@{{ controller2_ip_man

my_ip = {{ hostvars[inventory_hostname]['ansible_ens3f1']['ipv4']['address']
}}
