Every time I Launch an image other than cirros from Horizon, i get an error "No valid hosts". This time I thought id try doing it from the command line.

Questions.

What are the minimum arguments required to launch an error free instance?

I used : nova boot --flavor m1.tiny --image cirros-uec command_line_VM but this launched into an error state.

How do I assign it an ip address when (I assume) I do not have neutron installed (how are the other VMs in horizon assigned IP addresses?).

neutron net-list: PublicUR endpoint for network service in RegionOne region not found
