Comment 13 for bug 1752540

Hi,

I add to revert this commit it the latest 16.0.11 release,

each time os_nova is failing on cell_v2 playbook :

I don't know how the delegation is working, from the deployer machine, /etc/hosts is not populated but I assume the name to resolve from inventory.

On a controller node, I can resolve and SSH into os-rone-cp-01_nova_conductor_container-dbee0504.

From a compute node I can resolve but not SSH into os-rone-cp-01_nova_conductor_container-dbee0504
