Hello Luca
Name: openstack-networks
Type: OpenStack Networking
Description:
Provider URL: http://openstack.example.com:9696
I assume Networking Plugin: Open vSwitch
Yes, i confirm.
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).
No i haven't defined any security policy, explicitly. I'm using a network
defined through horizon without any special option.
This are the output of the commands you asked from a node where a vm
that is attached to a neutron network is running:
Yes, this is what I needed.
[root@ovirt002 ~]# ovs-vsctl show
ovs-vsctl: unix:/var/run/openvswitch/db.sock: database connection
failed (No such file or directory)
This is quite worrying. Is ovs on the host working properly?
Can you please check: service openvswitch status
If not active: service openvswitch start
Who should enable it, a cluster confoguration or whatl else? I'm using
ovirt-node-ng, i suppose that openvswitch is already installed (didn't
check).

What do you mean?
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>
Where i find the xml file?
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' |

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