Anda,

Will you be able to join the OpenContrail summit today? The Zoom link is below if you weren't able to make advance plans to join us in person in Austin. Hopefully the presentations will be helpful and there will be time for discussion directly related to this topic.

Subject: [openstack-dev] Neutron exception when creating a network using Contrail R4.1 and OpenStack Ocata

Hi all,

I am struggling with Contrail R4.1 and OpenStack Ocata on Ubuntu 16.04.2.
I managed to install Contrail R4.1 on Ubuntu 16.04 using contrail-installer package and to successfully start all Contrail processes.
Then, I installed OpenStack Ocata using devstack. Unfortunately, I am facing some errors.

Worth mentioning that I have also installed only OpenStack Ocata without Contrail on Ubuntu 16.04 and it worked without any errors.

Some of the errors I have encountered with OpenStack Ocata and Contrail R4.1 are:
If I issue: 'neutron net-list', works fine but 'neutron --debug net-create net1' returns:

>From q-svc logs, I've found:

Also, when I try to create the network using Contrail GUI, I have the following error:
Error: Parent project cannot be found: Unknown id: project default-domain:admin


Do you have any idea why this happens?


Thanks,
Anda
