I assume Networking Plugin: Open vSwitch

Do you have any security groups defined for the vnic profile on your external network?

Looking at the output you provided is seems you do.The qpb bridge and the qvb/qvo veth pair are created when the security groups are present.

Can you try without the security groups? This would connect your vm vnic right into the ovs integration bridge (br-int).

Yes, this is what I needed.

This is quite worrying. Is ovs on the host working properly?

Can you please check: service openvswitch status

If not active: service openvswitch start

Add 2 ports in openstack directly

Add 2 nics on vm's, specifying the libvirt xml for the interfaces:

<interface type="bridge">
  <model type="virtio"/>
  <source bridge="br-int"/>
  <virtualport type="openvswitch">
    <parameters interfaceid="<neturon port id>"/>
  </virtualport>
</interface>

If the openstack neutron plugin works correctly, the ports should be connected to the osn network.

Yes, i know. The network is defined by neutron, which has it's own dhcp server.

What do you mean?

there is no firewall between openstack controllers and ovirt
engine/hosts. My doubt is about configuration, i've configured in this
way:

Name: openstack-networks
Type: OpenStack Networking
Description:
Provider URL: http://openstack.example.com:9696

Flagged read-only and requires authentication

Set the authentication and tested, reports everything ok.

Nothing else has been configured. I didn't found any documentation
that clarified if is enough.

After powering on i see on openstack this:

[stack@opstrio1101 ~]$ openstack port list | grep 00:1a:4a:16:01:51
<-- this is mac address of oVirt VM
| 86c46fed-dddf-4776-a765-27d4e52e861c | nic1
                        | 00:1a:4a:16:01:51 | ip_address='172.25.7.4',
subnet_id='280a98ad-0fd5-4961-a307-d1bfea8355cd'     |

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

If you need other clarifications i'll dig without problem in this env.
