Open Stack

Hi Venkat,
I've verified if eth1 was mapped on br-int and it was not. So I've
unstacked and restart everything and than eth1 was mapped. Now it works.
Thanks.

There is still a problem when I restart the ODL controller.
In fact after restarting ODL if I try to add a network I have this error in
Openstack:

*Error: *Failed to create network "Net": create_network_postcommit failed.

And if I try to create a new instance:

*Error: * Failed to launch instance "asd": Please try again later [Error:
No valid host was found. Exceeded max scheduling attempts 3 for instance
87a3545e-e067-4193-8aaf-8bfa9de6385d. Last exception: [u'Traceback (most
recent call last):\n', u' File "/opt/stack/nova/nova/compute/manager.py",
line 2081, in _do_build_and_run_in].

What happens?
I don't think that I have to reinstall everything everytime that I restart
the controller...

Thanks for your support
