[Libguestfs] error during virt-sparsify

[Illia Svyrydov]

Hello,

I'm using *virt-sparsify* for compressing image file

[ash2] jenkins at b-imagebuilder-worker-r13h17-prod:~/workspace/imagebuilder/packer/output$
virt-sparsify --compress
 /data/home/jenkins/workspace/imagebuilder/packer/output/packer-vm.qcow2
/data/home/jenkins/workspace/imagebuilder/packer/output/packer-vm.qcow2.sparsified
Input disk virtual size = 41943040000 bytes (39.1G)
Create overlay file in /data/tmp/ to protect source disk ...
Examine source disk ...
Fatal error: exception Guestfs.Error("guestfs_launch failed.
This usually means the libguestfs appliance failed to start or crashed.
See http://libguestfs.org/guestfs-faq.1.html#debugging-libguestfs
or run 'libguestfs-test-tool' and post the *complete* output into a
bug report

Here is *libguestfs-test-tool* output

I would really appreciate any help or hint

Have a nice day,
Illia Svyrydov
