I was working on upgrading some of our POWER8 ppc64le nodes and ran into the following issue with the libguestfs package that's currently in updates:

$ yum upgrade libguestfs

Error: Package: 1:libguestfs-1.40.2-5.el7_7.1.ppc64le (updates)
           Requires: kernel-core
 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

Thanks!
