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-differ... 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(a)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 Rich. -- Richard Jones, Virtualization Group, Red Hat http://people.redhat.com/~rjones Read my programming and virtualization blog: http://rwmj.wordpress.com virt-df lists disk usage of guests without needing to install any software inside the virtual machine.
