Cannot create network with Openstack

[fclaudiopalmeira]

The Cassandra container and the Vrouter-Agent, the analytics database kafka and cassandra, and the config database cassandra containers stay on the Reastarting state forever, the vrouter agent being down is probably the reason that we cant create networks or list them.
run docker ps and you will see it.
What is happening?i have tried installing the kernel-3.10.0-693.21.1.el7.x86_64, but unfortunately it seems that either it won´t be available for you to downgrade after upgrading Centos or it is not available at the repositories anymore.
How do we solve that?

Just to add , I will be trying installing the kernel below and reinstall everything.

http://mirror.centos.org/centos/7.4.1708/centosplus/x86_64/Packages/kernel-plus-3.10.0-693.21.1.el7.centos.plus.x86_64.rpm

[fclaudiopalmeira]

You should not install the Centosplus Kernel, install the exact one mentioned in the docs instead:
yum install http://mirror.centos.org/centos/7.4.1708/updates/x86_64/Packages/kernel-3.10.0-693.21.1.el7.x86_64.rpm
But just to tell you in advance, still the issue remains.

After adding the CONTROLLER_NODES: directive I was able to create the network correctly.
Best Regards

@egomezgarreaud I am facing the same error, which directive are you referring to? Is is similar to this: contrail_configuration:
CONTROL_NODES:

however I have tried the above and ran all the playbooks again and still stuck with the same issue

I was facing the same problem and the issue was with Cassandra container. It got stuck on restarting state. Please check if Cassandra is running properly and if it's stuck on restarting state then check its logs.
$ docker logs {container-id}
In my case I did set the hostname and everything worked fine for me.
$ hostnamectl set-hostname {host-name}

If the above solution doesn't work then please paste the logs of containers that are in restarting state.

@AbdulMalik206267 this is what i see, The horizon dashboard itself isn't opening now.
