Hi Emilien,

Which mode are you running OVS in?  VLAN or tunneled?  If you are using
VLAN-mode (default) you need to add some physical interface to br-int, so
that VLANs are trunked to the physical network.  Is it possible that eth1
was also the interface you were using for IP communication on the box?
 That definitely won't work with OVS or the linux bridge.  I'll improve the
docs around that to make this more clear.

Can you ping me with the error messages (can be offlist)?  I still don't
understand what you misconfigured, or how you fixed it.

Great to hear.  As I mentioned in a previous post, Horizon + Quantum isn't
complete.  You won't be able to create networks using Horizon, or boot VMs
while specifying a particular set of vNICs.  If you're interested in
helping this work move forward more quickly, I'm happy to put you in touch
with the right people.
