I guess the problem is that I was creating *external* _and_ *shared*
network, but if I don't want to use floating IPs from that network I
probably don't need the network to be external, right?

Thank you, I will test it further.

I currently have only 1 l3-agent running, but it's suboptimal. I would
like to have L3-HA for the floating IPs and DVR for the shared and
tenant networks, but as far as I know it's not currently supported. I
plan to deploy the production cloud after Kilo release, and crossing
my fingers...

Floating IPs are currently configured on br-ex.
