Dears, I'm new to the list. We're just trying to introduce a demo install of openstack in our network. Our intention was to use 5 machine, already installed with ubuntu-mini 20.04. ostack1 as control node ostack2 -| ostack3 -| AS COMPUTE NODE ostack4 -| ostack5 -| ostack4 - ostack5 also as block storage node, they are connected on a direct storage (sas) where we deployed lvm with a vg named "cinder_volumes". All nodes both are on a /24 network (192.168.32.0/24) behind a router (32.254) and also on a "private" network (10.255.255.0/24) which just interconnect nodes themselves. We inteded to deploy openstack using openstack-ansible, available on github, last stable release. You can see our user_config as attachment. setup-hosts playbook runs with no errors. setup-infrastructure playbook hangs on RUNNING HANDLER [repo_server : reload nginx] **************************************************************************************** FAILED - RETRYING: reload nginx (1 retries left). fatal: [ostack1_repo_container-aabb6a12]: FAILED! => {"attempts": 5, "changed": false, "msg": "Unable to start service nginx: Job for nginx.service failed because the control process exited with error code.\nSee \"systemctl status nginx.service\" and \"journalctl -xe\" for details.\n"} Looking at log I can see that nginx coudn't start due to "Cannot assign requested address: 99" error. I suppose that must be a mistake in the deploy file? Many thanks for your suggestion, and pls, be sorry for my poor english :) Nick
