This will help you in better way.

   image=nova.images.find(name="Ubuntu 12.10 cloudimg amd64") 
   flavor=nova.flavors.find(name="m1.tiny")
   my-nic= [{"net-id": myNet.id, "v4-fixed-ip": str(ip_address)}]
   instance=nova.servers.create(name="samplehost", image=image, flavor=flavor,nics=my-nic)

oh, sorry, novaclient use boot instead of create, so the nova help command is nova help boot

i think the common way to solve such problem is:

1. find documents in http://docs.openstack.org for i.e. http://docs.openstack.org/api/openstack-compute/2/content/NetworksSection.html (http://docs.openstack.org/api/opensta...) , it may not be right, but can provide a general knowlege, like it said:"The parameter fixed_ip is used only when network uuid is specified; also, when port is specified, network uuid and fixed_ip are properties of the port and are ignored. Omit fixed_ip and (network) uuid to avoid validation errors."
2. use cli help, for this case: nova help create, it can give you a direct param help message
3. read the source code, code is power for i.e. in novaclient/base.py:

384 if nics is not None: 385 # NOTE(tr3buchet): nics can be an empty list 386 all_net_data = [] 387 for nic_info in nics: 388 net_data = {} 389 # if value is empty string, do not send value in body 390 if nic_info.get('net-id'): 391 net_data['uuid'] = nic_info['net-id'] 392 if nic_info.get('v4-fixed-ip'): 393 net_data['fixed_ip'] = nic_info['v4-fixed-ip'] 394 if nic_info.get('port-id'): 395 net_data['port'] = nic_info['port-id'] 396 all_net_data.append(net_data) 397 body['server']['networks'] = all_net_data

so, nics is a list of dict, each may have key of net-id, v4-fixed-ip, port-id, in your case, you can use nova.servers.create(name="samplehost", image=image, flavor=flavor,nics=[{'net-id': '9883ec93-4589-4fa2-825d-7a9a8215fd07'}])

it may not be right, because it depends on which version of novaclient you have installed. you can check and fix it

good luck
