Open Stack

Hello,

NetApp CI has been facing the same problem.

Here is a local.conf we have been using in our CI:
https://paste.openstack.org/show/807484/
The tests had basically same output described by Goutham:
https://paste.openstack.org/show/807486/

I have also tried this in a development environment in our lab but the same
issue is occurring.
