Hello Marcin,<br>

<br>
</span>Yes, i know. The network is defined by neutron, which has it's own dhcp server.<br>

<br>
</span>there is no firewall between openstack controllers and ovirt<br>
engine/hosts. My doubt is about configuration, i've configured in this<br>
way:<br>
<br>
Name: openstack-networks<br>
Type: OpenStack Networking<br>
Description:<br>
Provider URL: <a href="http://openstack.example.com:9696" rel="noreferrer" target="_blank">http://openstack.example.com:9<wbr>696</a><br>
<br>
Flagged read-only and requires authentication<br>
<br>
Set the authentication and tested, reports everything ok.<br>
<br>
Nothing else has been configured. I didn't found any documentation<br>
that clarified if is enough.<br>
<br>
After powering on i see on openstack this:<br>
<br>
[stack@opstrio1101 ~]$ openstack port list | grep 00:1a:4a:16:01:51<br>
<-- this is mac address of oVirt VM<br>
| 86c46fed-dddf-4776-a765-27d4e5<wbr>2e861c | nic1<br>

<br>

<br>
</span>This are the output of the commands you asked from a node where a vm<br>
that is attached to a neutron network is running:<br>
