The log output from command " ./virt-sparsify --inplace -v -x

Thanks. This is actually a bug in libguestfs. In the following
function which is called from virt-sparsify early on:
https://github.com/libguestfs/libguestfs-common/blob/9d40590852e0755d4719...
if the "lvs" feature is not enabled then calling guestfs_lvs will
fail:
libguestfs: trace: lvs
guestfsd: <= lvs (0xb) request length 40 bytes
guestfsd: error: feature 'lvm2' is not available in this
build of libguestfs. Read 'AVAILABILITY' in the guestfs(3) man page for
how to check for the availability of features.
guestfsd: => lvs (0xb) took 0.00 secs
libguestfs: trace: lvs = NULL (error)
and cause virt-sparsify to exit.
Can you try the attached patch to libguestfs/common ?
Rich.

Difficult to say. What is the complete output from virt-sparsify -v -x .... ?
