Description of problem:
In a previous Bug 1114150 for OpenStack 4, sysfsutils was identified to be an important component of openstack-nova and Cinder and was included as a dependency of openstack-nova. However, the dependency appears to be missing in OpenStack 6. This caused an issue with a customer deployment of OSP 6.

Version-Release number of selected component (if applicable):
openstack-nova-compute.noarch 2014.2.3-31.el7ost

How reproducible:
Very

Steps to Reproduce:
1. Install OSP 6 using the OSP installer (Foreman)
2. Configure cinder storage using a fibre backend (3par in this case)
3. Try to attach a volume to an instance

Actual results:
Volume attach fails

Expected results:
Volume should properly attach
