[Libguestfs] libguestfs error: need help troubleshooting

[Deepti Navale]

Hi,

I'm trying to manually create a rhel7 image using the qemu-img and virt-install commands. I'm re-testing a procedure I previously wrote with the new grub commands that a customer suggested we add in. This procedure is available at: http://file.bne.redhat.com/dnavale/docs/review/RH-guides/AG-020715/#sect-create-images

As in the procedure, I'm able to run all steps successfully until step 12. When I run the virt-sysprep command, I get the following errors:
--------------
➜  RHEL7  sudo virt-sysprep -d rhel7 --format qcow2
[   0.0] Examining the guest ...
Fatal error: exception Guestfs.Error("qemu-img: /tmp/libguestfsStQSH1/overlay1: qemu-img 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")
--------------

Then I updated the qemu-img package and started getting this error:
--------------
➜  RHEL7  sudo virt-sysprep -d rhel7            
[   0.0] Examining the guest ...
Fatal error: exception Guestfs.Error("/usr/bin/supermin 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")
--------------

I'm using the following packages: libguestfs-tools-c-1.26.10-1.fc20.x86_64, libguestfs-1.26.10-1.fc20.x86_64 on a Fedora20 machine. And I used 'yum install -y libguestfs-tools-c' command to install the package.

The complete, unedited output of the libguestfs-test-tool command is as below:

Please help me resolve this issue and get a compatible rhel7 image that I can upload to OpenStack and create an instance from.
