Description Timothy Redaelli 2019-04-16 11:02:29 UTC 
This bug was initially created as a copy of Bug #1699689

I am copying this bug because: 



Description of problem:
Openvswitch fails to start because of dependencies of bridge module during overcloud deploy of nodes with infiniband interfaces.

Version-Release number of selected component (if applicable):

openvswitch-2.9.0-97.el7fdp.x86_64
Red Hat Openstack Platform 13

How reproducible:

Always

Steps to Reproduce:

run overcloud deploy with overcloud nodes with infiniband interfaces

Actual results:

Overcloud deploy fails because it is not able to communicate with overcloud nodes

Expected results:

Overcloud deploy should be able to communicate with overcloud nodes

Additional info:

Change rmmod to modprobe -r  in /usr/share/openvswitch/scripts/ovs-ctl
after this change the deployment was successful
