    LGTM - Built agent RPMs for CentOS 7 from this PR branch and installed 
those on the KVM hypervisors. Run the management server also from this branch 
and was able to add a CentOS 7 host both through Marvin and UI without manual 
intervention. Just like you can do on master.
    
    Thanks for back porting to 4.5 @wido !
