More info:

I've tried associating the new network with the project by issuing:
nova-manage network modify 10.1.2.0/24 --project=admin

This did not help. So I wanted to debug the issue and hardcoded the 
network id into nova/db/sqlalchemy/api.py:
#def network_get(context, network_id, session=None):
def network_get(context, 2, session=None):

Now instances start. Do I need to create a new project *after* the new 
network is created? Testing... Yes, that works.

Is there a bug for: deleted networks are not automatically and cannot be 
manually disassociated from projects?

Comments:
There seems to be some quite some issues with regards to failing 
gracefully and clean up around the project. For example, any of the 
failed instances that I started while debugging this have to manually be 
removed from the database. Shouldn't a warning be issued that the vm 
doesn't exist and references to it were removed from the system?
