<br>
<br>
Description<br>
===========<br>
After Openstack installed, it's adding centos82.localdomain on /etc/hosts and causing OVN Southbound (ovn-sbctl show) using this centos82.localdomain. But after the machine rebooted, "ovn-sbctl show" is showing the correct fqdn: centos82.domain.tld, and it is causing VM instantiate error (Refusing to bind port <UUID> due to no OVN chassis for host: centos82.localdomain).<br>
<br>
<br>
Steps to reproduce<br>
==================<br>
Base installation: https://docs.openstack.org/project-deploy-guide/tripleo-docs/latest/deployment/standalone.html<br>
Tested on Centos 8.2 latest, tested several times on Train and Ussuri. <br>
100% reproduceable. <br>
<br>
<br>
Set the custom FQDN hostname<br>
<br>
<span style="font-style: italic;">hostnamectl set-hostname centos82.domain.tld<br>
hostnamectl set-hostname centos82.domain.tld --transient (also tested with or without this line)</span><br>
<br>
<span style="font-style: italic;">cat /etc/hosts<br>
127.0.0.1 centos82.domain.tld localhost localhost.localdomain localhost4 localhost4.localdomain4<br>

<br>
<br>
<br>
Follow the guide to install (without ceph)<br>
<br>
<font size="1">(<span style="font-weight: bold;">Issue 1B</span>) with ceph was having another error, just tested once on Train:<br>
<span style="font-style: italic;">fatal: [undercloud]: FAILED! => {<br>

<br>
<br>
<br>
<br>
All will be installed successfully, and able to instantiate VMs and these VMs are able to ping to each other. <br>
<br>
Then do "reboot" on this standalone host/server. <br>
<br>
Do instantiate a new VM, and then this new VM status will be ERROR. <br>

[root@centos82 /]# <br>
<br>
<br>
So that the OVN seems could not bind the port to different hostname (that already changed). <br>
<br>
<br>
Environment<br>
===========<br>
1. Exact version of OpenStack you are running: Any, tested Train and Ussuri<br>
2. Centos 8.2 latest update<br>
Others (without ceph): https://docs.openstack.org/project-deploy-guide/tripleo-docs/latest/deployment/standalone.html<br>
<br>
<br>
<br>
Workaround<br>
==========<br>
Don't use custom domain, instead use "localdomain" as on the document<br>
<br>
<span style="font-style: italic;">hostnamectl set-hostname centos82.localdomain<br>
<br>
[root@centos82 ~]# cat /etc/hosts<br>
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4<br>
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6<br>
192.168.156.82 centos82.localdomain centos82</span><br>
<br>
Deploy, test instantiate, reboot, test instantiate, and working perfectly fine. <br>
<br>
<br>
Question: For custom domain, where did I do wrongly? Is it expected or kind of bugs?<br>
