<p>Hmmmmm. I just succeeded in setting up my Packstack after
removing IPv6 from the kernel and cleaning out ifgcfg-eth0. Since
I don't need IPv6, I am good. My config:<br>

<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>
