Hi all, 
I have ovirt 4.1 with self hosted engine. 
I have performed lately yum update -y on the hosts and at next yum update at both hosts I get the following dependency issue: 
Error: Package: rubygem-fluent-plugin-secure-forward-0.4.5-1.el7.noarch (centos-opstools-release)
           Requires: rubygem(proxifier)
