Open Stack

Hi Jean-Philippe Evrard and Jesse,

Thank you both for your responses.
Finally i succeeded in deploying DVR setup but i don’t know if my approach
is good or not. I am going to describe it for the sake of sharing.

I used newton tag 14.0.2 and my scenario is VLANs tenant networks+flat
external network+DVR. Inside  neutron agents containers i created 2 OVS
bridges, br-prv for tenant networks and br-floating for the flat network,
then i attached eth11 and eth12 as ports accordingly, like this:

*ovs-vsctl add-br br-floating*
*ovs-vsctl add-br br-prv*
*ovs-vsctl add-port br-prv eth11*
*ovs-vsctl add-port br-floating eth12*

In the compute nodes it was a bit hard for me as the equivalent  of eth11
and eth12 interfaces don’t exist, also OpenvSwitch cannot accept br-vlan to
be a port for both  br-prv and br-floating. So, what i ended up doing is
creating 2 *internal* OVS ports one for br-prv and the other for
br-floating, then i added them to br-vlan bridge in
 /etc/network/interfaces file, like this:

*auto p_prv*
*allow-br-prv p_prv*
*iface p_prv inet manual*
* ovs_type OVSIntPort*
* ovs_bridge br-prv*


*auto p_floating*
*allow-br-floating p_floating*
*iface p_floating inet manual*
* ovs_type OVSIntPort*
* ovs_bridge br-floating*

*auto br-vlan*
*iface br-vlan inet manual*
*        bridge_stp off*
*        bridge_waitport 0*
*        bridge_fd 0*
*        bridge_ports enp4s1 p_prv p_floating*


I hope we could get other solutions that use openstack-ansible with DVR to
select the best one since DVR is new in openstack-ansible.

Best regards,
Hamza
