I'm not exactly sure what's wrong. There are two things you can try: (1) Upgrade to a later supermin. The latest version is 5.1.16, which is available here: https://people.redhat.com/~rjones/libguestfs-RHEL-7.3-preview/ It is also much faster than 5.1.10.

(2) With 5.1.16, if it still doesn't work, strace it, and let us see the full strace.log: strace -o /tmp/strace.log -s 1024 \ supermin5 --build -f ext2 -v -v -v /usr/lib64/guestfs/supermin.d \ -o /tmp/appliance.d Rich. -- Richard Jones, Virtualization Group, Red Hat http://people.redhat.com/~rjones Read my programming and virtualization blog: http://rwmj.wordpress.com virt-df lists disk usage of guests without needing to install any software inside the virtual machine.
