[Libguestfs] Help, it's not working!

[Sa Kh]

Hi,

*1. What are you trying to do?*
I was trying to clean up a virtual machine image in place. I followed the
instruction in the Openstack documentation to do so. Here is the link:
http://docs.openstack.org/image-guide/ubuntu-image.html

*2. What exact command(s) did you run?*
virt-sysprep -d trusty

*3. What was the precise error or output of these commands?*
Examining the guest ...
Fatal error: exception Guestfs.Error("/usr/bin/supermin-helper exited with
error status 1.
To see full error messages you may need to enable debugging.
See http://libguestfs.org/guestfs-faq.1.html#debugging-libguestfs")

4.*Enable debugging, run the commands again, and capture
the complete output. Do not edit the output.*

*5.Include the version of libguestfs, the operating system version, and how
you installed libguestfs (eg. from source, yum install, etc.)*
version : virt-sysprep 1.24.5
operating system version : ubuntu 14.04 trusty
installation method: apt-get install

I need to add that the system i ran this command on, is an Openstack
controller.

I appreciate your help.

Regards,
Sajad
