Cool! As I mentioned, looking at the python-novaclient code's --nic option should give you everything you need. Its worth noting that right now Quantum Manager only supports specifying the network using --nic, not setting the VM IP. > > Tres - let me know if there is any overlap with what you planned on working > on. > > Dan - if we remove the "Create Network" button, what is the right way to > create networks for testing purposes? The "administrator" needs to create them using nova-manage (stack.sh creates one for you already, but you can create more using the syntax: /opt/stack/nova/bin/nova-manage network create --label=net2 --fixed_range_v4=13.0.0.0/24 See the Quantum Admin Guide for details (http://docs.openstack.org/incubation/openstack-network/admin/content/index.html).
