You can use the os-create-server extension to do this.  We recently added
support for this extension to the nova client utility using the "--nic"
option, though I believe it only went in during Essex-2, so I'm not sure if
it would be in a distro like StackOps yet.  The following command would
create a VM connected to quantum network
0c02f3d3-204a-4e37-b820-5d15e6d74a9f. :

nova boot --flavor 1 --image 07f3c46c-5062-4837-b43d-ec1a93b894dc --nic
net-id=0c02f3d3-204a-4e37-b820-5d15e6d74a9f test1
