neutron

failed to create network by dashboard

Asked by Yi Liu

1.Create a network by command 'neutron net-create' with parameter '--tenant-id' is OK.
# neutron net-create --tenant-id 42b15ed7cc7d4986a1cc1ccdda844eca test_net
Created a new network:
+---------------------------+--------------------------------------+
| Field | Value |
+---------------------------+--------------------------------------+
| admin_state_up | True |
| id | cccb503b-03f7-4ac3-a8c2-82dd7f1c945b |
| name | test_net |
| provider:network_type | vlan |
| provider:physical_network | physnet1 |
| provider:segmentation_id | 3 |
| shared | False |
| status | ACTIVE |
| subnets | |
| tenant_id | 42b15ed7cc7d4986a1cc1ccdda844eca |
+---------------------------+--------------------------------------+

2.Create a network by command 'neutron net-create' without parameter '--tenant-id' , failed!
# neutron net-create test_net
Running without keystone AuthN requires that tenant_id is specified

3.create network on dashboard, failed, error message as below:
Error: Failed to create network "test_net": Running without keystone AuthN requires that tenant_id is specified

However, there is no place to set tenant_id when create a network on dashboard!!!

I think the tenant_id should be included in the request context?? But how?

aren't u are using keystone as authentication module?

neutron.conf:
[DEFAULT]
auth_strategy = keystone

OpenStack Dashboard is expected to use keystone-enabled OpenStack. When creating a network, Dashboard passes keystone token to Neutron and Neutron retrieves tenant_id or other information such as roles from Keystone based on the passed token.

I believe yong's suggestion will address your problem. It seems you already enable keystone because you succeed to login Dashboard, but it seems neutron is not configured to use keystone.
