The kernel that fails isn't the Red Hat kernel, so I suppose it lacks
the right drivers or has some different configuration which breaks
libguestfs.

You can tell libguestfs to use a different kernel by setting the
SUPERMIN_KERNEL parameter and removing the /var/tmp/.guestfs-*
directory between runs.  See the FAQ here:

http://libguestfs.org/guestfs-faq.1.html#broken-kernel-or-trying-a-different-kernel

For comparison the successful run is using the ordinary CentOS kernel:

[    0.000000] Linux version 3.10.0-957.10.1.el7.x86_64 (mockbuild at kbuilder.bsys.centos.org) (gcc version 4.8.5 20150623 (Red Hat 4.8.5-36) (GCC) ) #1 SMP Mon Mar 18 15:06:45 UTC 2019
