[Libguestfs] libguest-test-tool error report

[Mark Husted (hustedm)]

Hello Rich,

Well, that stinks.

I really appreciate the quick responses.  Thank you for your time and effort, too.  I will see what I can do to solve this problem some other way.  Maybe I can virtualize my disk image maker.

Thanks,
Mark

The problem is that the disk image uses qcow2 features which were added in RHEL 7.  RHEL 6 is simply unable to read or process this disk image.

The only solution here is to update the host to RHEL 7 / CentOS 7.
