virt-sparsify: error: libguestfs error: could not create appliance through
libvirt.

Try running qemu directly without libvirt using this environment variable:
export LIBGUESTFS_BACKEND=direct

Original error from libvirt: Cannot access storage file
'/u01/workspace/OL8U10_x86_64-oci-b0/tmp.BObiwxXYR5/sparsify6d0789.qcow2'

If reporting bugs, run virt-sparsify with debugging enabled and include the
complete output:

virt-sparsify -v -x [...]

See https://libguestfs.org/guestfs-faq.1.html - section ""Permission denied" when running libguestfs as root"

Basically, you should not run this script as root as mentioned in this project's README:

Run the builder as a non-privileged user
