thomas,

Your very first email refers to libguestsfs 1.40.2, where is
libguestfs-test-tool reports refer to libguestfs 1.38.2.
Anyway, can you download pre-built FIXED appliance matching your
libguestfs version and try using it?

Here is you can find pre-built FIXED appliances:
http://download.libguestfs.org/binaries/appliance/
Download and untar it anywhere.
Then launch libguestfs-test-tool specifying path to fixed appliance like this:

LIBGUESTFS_PATH=/path/to/fixed-appliance libguestfs-test-tool

Does it make any difference?

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@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

yes,  this system tailor it's kernel ,reduce the 
"CONFIG_VIRT_DRIVERS=y " ,this cause the vm fail to start .
after add the virtio driver config ,then recompile the kernel ,
libguestfs-test-tool run successfully .
 thanks for help !
