multinic nova network-create Unexpected API Error

[surajkumar]

Hi,

I was going through the the openstack link and doing hands on practice as well.

link: http://docs.openstack.org/admin-guide/compute-networking-nova.html

Heading: Using multinic

Below error I got after running the command:

stack@mirantis-HP-Z400-Workstation:/opt/devstack/devstack$ nova network-create first-net --fixed-range-v4 20.20.0.0/24 --project-id nova
ERROR (ClientException): Unexpected API Error. Please report this at http://bugs.launchpad.net/nova/ and attach the Nova API log if possible.
<type 'exceptions.NotImplementedError'> (HTTP 500) (Request-ID: req-8ee17d86-7d8b-438a-a80e-26389fbf565a)
stack@mirantis-HP-Z400-Workstation:/opt/devstack/devstack$
stack@mirantis-HP-Z400-Workstation:/opt/devstack/devstack$

I am using mitaka version in devstack.

Thanks and Regards,
Suraj

Thanks for taking the time to file a bug! Could you provide your n-api and n-net logs?

[surajkumar (surajkumar47)]

Hi Augustina,

Please find the attached log, there is not any log file with the name of n-net.

[Augustina Ragwitz (auggy)]

Thanks for the logs! I've pasted the full error below. The error you are seeing typically happens if you are using neutron networking and you try to run nova-net commands. Check the "use_neutron" value in your nova.conf. If that doesn't appear to be the issue, then please attach your nova.conf to this bug.

Thanks for the reply!

In my nova.conf the variable is marked as true

"use_neutron = True"

Plz correct me if i am wrong, It means that my devstack is using neutron not nova-network ?

[Augustina Ragwitz (auggy)]

Based on your config, your devstack is using Neutron for networking. Nova-network commands won't work.
