https://www.redhat.com/archives/anaconda-devel-list/2011-March/msg00129.htmlSorry again for late reply, this issue has been fixed and problem was with Library we were missing some library at the time of building ISO (creating initrd and stage2 images)
Hope this will help someone... and just update on setColor method is available in python 2.7 or later version....
