That certainly demonstrates the bug.  I'm unclear why it would be
happening, but perhaps you can run the following commands and send me
the results:
LIBGUESTFS_BACKEND=direct guestfish --ro -a fc21-64.qcow2 -i find / > files
LIBGUESTFS_BACKEND=direct virt-cat -a fc21-64.qcow2
/etc/selinux/targeted/contexts/files/file_contexts / > file_contexts
rpm -qf /usr/sbin/setfiles > setfiles.version
Note that the first command produces a list of all filenames within
the virtual machine, which might be sensitive information, so you may
wish to send me that file privately.
Thanks,
Rich.
