I  assume  Quantum Manager is enabled  ( the following flag specified in nova.conf )

network_manager=nova.network.quantum.manager.QuantumManager

Remove the existing network. Restart the Network Services .

Issue the below to create the 2 different networks as per your requirment . It Should work.

nova-manage network create --label=public --fixed_range_v4=10.0.1.0/24<http://10.0.1.0/24>

nova-manage network create --label=test-1 --fixed_range_v4=10.0.2.0/24<http://10.0.2.0/24>  --project_id=64a1c0f3-572b-4349-993d-36c06b746006

i think you should use --vlan=<vlanid> in command nova-manage network create

I thought by default nova-manage try to use vlan_start (default is vlanid 100) to insert it in db table networks. and if you already have one network with vlanid100 , it should return such error about duplicated vlan.

what is the type of network_manager in you configuration?

According doc: http://docs.openstack.org/incubation/openstack-network/admin/content/Net-Create-dle455.html

when I create the second network, it return errors:
