I've installed nova from the launchpad ppa and just updated this morning
I have three 172.16.x.0/24 networks created with
nova-manage network create private 172.16.1.0/24 1 255
and modified using the method outlined for Vlan manager in the nova administrator documentation (create a script to modify the database to add virtual bridge interfaces, etc)
euca-run-instance fails with the following error messages in /var/log/nova/nova-networking:
