      The issue happens when VMWare VM has a too small NVRAM file.
      It would be nice to point to the KCS I just wrote: https://access.redhat.com/solutions/7023631

      This KCS is VMWare specific. If the issue happens on other hardware, then likely there is some Firmware issue to deal with.

      Version-Release number of selected component (if applicable):

      all releases

      How reproducible:

      Always

      Steps to Reproduce:
      1. Create a VMWare VM at Hardware Level 13 in UEFI
      2. Install RHEL7 and update it
      3. Try to leapp it

      Actual results:

      See above

      Expected results:

      Error + KCS
