Thanks. I have joined the channel.
AIO doc says minimum 8 vcpu's are required. Is that a mandatory requirement? My laptop has less vcpu's. if its just a test deployment you can run with less we normally recommend 8G for ram and 8vcpus for an all in one deployment of openstack but it will work with 4 you just wont be abel to run many vms. on the ram side i have deployed all in one node in 6G of ram but again that teands not to leave much room for vms.
i havent realy used OSA but the requirements should be more or less the same.

In my setup I have deployed everything on real hardware with VLANs etc to mimic production style. Are you trying to deploy openstack-ansible (AIO)? https://docs.openstack.org/openstack-ansible/latest/user/aio/quickstart.html
Let me assume you are trying to deploy an openstack-ansible AIO model on a virtual box. In that case you don't need any special networking, all you need is a single virtualBox nic in Bridge mode and follow AIO instructions. Why don't you join openstack-ansible IRC, it's hard to answer interactive questions here.

Hello Satish,
I am unable to ssh/ping the CentOS 8.2 machine after following the steps mentioned in your document. I am trying this POC using Oracle Virtualbox. The vm got 192.168.0.x IP from DHCP in my wifi router.
Till bootstrap, the SSH session was alive. But after a while I lost access to the vm. Now If I do ip a, I don't see the 192.168.0.x IP to any interface.
What can be the issue?
Regards, Amey.

Hi Amey,
I am running my cloud using openstack-ansible on centos 7.5 (on Production) and 8.x (on Lab because centos 8 soon end of life, my future plan is to migrate everything to ubuntu ).
Answer to your question is you have two way to configure networking using OSA
1. Use systemd-networkd here is the example - http://paste.openstack.org/show/802517/ 2. Use package network-scripts (This is legacy way to configure network on centOS /etc/sysconfig/network-scripts/* style) - You can see example on my blog how to deploy OSA on centos - https://satishdotpatel.github.io//build-openstack-cloud-using-openstack-ansi...

Hi Amey,
The documentation that you linked to is specifically for the ansible deployment host, which can be separate from the OpenStack target hosts if you wish. The only requirement is that it has ssh access to the target hosts, by default this would be via the network attached to br-mgmt on those hosts.
In terms of the target hosts networking, you should refer to https://docs.openstack.org/project-deploy-guide/openstack-ansible/latest/tar....
Yes I checked this reference.
OpenStack-Ansible does not prescribe any particular method for setting up the host networking as this tends to be specific to the individual environment or deployer preferences.
I am looking for an example where to put the interface configurations in CentOS 8. But, I am unable to find any references specifically for CentOS/RHEL. Hence I post the question here to get help from some1 who is already running OpenStack on CentOS 8.
Regards, Amey.
You should pick most appropriate network config tool for your OS/environment and create the bridges and networks listed in the table on the target hosts documentation.
I would always recommend starting with an All-In-One deployment https://docs.openstack.org/openstack-ansible/latest/user/aio/quickstart.html. This will generate a complete test environment with all the host networking set up correctly and will serve as a reference example for a production deployment.
Do join the #openstack-ansible IRC channel if you would like to discuss any of the options further.
Regards, Jonathan.
