Shinobu, I don't think you meant to write this bug to Fuel, but instead Ironic project.
You're using Red Hat Enterprise Linux 7 packages, not Fuel ones, so I don't think we can help you here.
If this is the case, please either report a bug directly to Ironic project or to Red Hat Bugzilla. If you have any questions, feel free to reopen this bug.
