Things starting to work !
When I boot boot cirros image with ip 10.0.0.1, I can ssh (even if it doesn't accept my password), but when I lauch tty-uec image (or other) with ip starting at 10.0.0.2, ssh tell "no route to host"

If it works on one image, but not another, this is probably an issue with the image itself.  The "no route to host" error is likely because the gateway interface 10.0.0.1 is arping for 10.0.0.2 and not getting a response.  Perhaps the image is not configured to use DCHP on the interface?  Or is not correctly launching?  I'd use VNC to login and check it out.

I sum up the actual conf

  *   br-int as bridge in OVS, no other conf (nothing in interfaces file), ifconfig show a 10.0.0.1 ip
  *   nova conf got public_interface=br-int / flat_network_bridge=br-int / flat_interface=eth0
  *   quantum manage the assignation successfully
Thanks
