Description of problem:
The issue appeared in the middle of installing rawhide release using the BFO installer. This issue appered in ESXi 5.1 and latest Oracle VirtualBox. The point is that it appered on different days. Normal release is installing just fine. I might have look into this problem myself but I dont have time right now. Also the installation was done just without any changing (the only thing I changed was the root password and set the user, I didnt even created the volumes manually but let the installation do the work)

Version-Release number of selected component:
anaconda-21.34-1

The following was filed automatically by anaconda:
