<p>More info: This is a VM running <i>CentOS 7.6.1810 </i>on a
Fedora KVM host. eth0 is bridged. I did disable and stop network
manager and firewalld on the guest.</p>

<div>Hi,</div>
<div><br>
</div>
<div>So, IIUC, your server has a single NIC, eth0, right?</div>
<div><br>
</div>
<div>Could you provide the configuration file for eth0 before
running packstack?, i guess you are using ifcfg files?<br>

<p>Now, it fails during network setup. My network connection

its only network interface <i>eth0 </i>has no IP address

<p>In the <i>network.pp.finished </i>file, I find various
