I also noticed that when I try: 
sudo ovs-ofctl dump-flows br-int
to check if the flow was installed properly I receive this message:

Moreover, in Karaf, I've done:
web:list
and I can see that the services related to neutron are active but in a failed web state.

Could this be helpful?Thanks

I'm sorry, I have another doubt about promiscuos mode.The controller node and the compute nodes, as you said, are created with vSphere. But in this environment there is not only those VMs that I'm using, but also some other. Who manages this system enabled in promiscuos mode the bridges that connect my VMs (data network), and the bridge related to the management network.I did not enabled the bridge that exposes externally ALL VMs that are in the server (security reasons). Could be this the problem?
Thanks

Hi Venkat,I've checked that everything is in promiscuos mode, the interfaces are enabled and I have also added the flow that you told me (it's the same of the wiki). Nothing has changed, links are still broken.Any other hypothesis or something that I could try?

Hi Silvia,


 


Thanks for your interest in this integration.



 Assuming you are using Helium release (these are some tested steps in Helium when the same problems were reported).


There are multiple things that you could do to debug this situation



a.      
If you are using vsphere to create the control node and compute VM’s then please enable the (Accept
 Promiscuous mode)


 



b.     
Sometimes, the Ethernet interfaces may not be “UP” so please check ifconfig and if the interface name does ot show up, it is probably
 nnot iun UP. Please bring it up manually ifup <interface_name>


 


 



c.      
Finally, try adding the default flow




ovs-ofctl --protocols=OpenFlow13 add-flow br-int priority=0,actions=output:CONTROLLER



 


in all the nodes and try the dlux GUI to cjheck if the links appeared.


 


 


Kindly let us know in case of any queries.


 


Regards,


Venkat G

Hi all,



I have installed openstack following the wiki for VTN integration, but when I visualize the topology I can see the switches but there are no links between them.




The stacking operation seems to be successful.




Someone can help me.




Ask if you need further details.




Regards
