Thanks for providing the libguestfs-test-tool output in a previous message. Here you're setting backend = "direct", and while that isn't necessarily a problem in itself, the libguestfs-test-tool output that you provided was for the (normal, for RHEL) libvirt backend. This could make a difference, so what's the output of: $ LIBGUESTFS_BACKEND=direct libguestfs-test-tool ? By the way, unless you have a specific reason to set 'LIBGUESTFS_BACKEND=direct' that you can articulate, it is best not to set this as it is less secure and less well tested. If you just copied that environment variable from somewhere without understanding why, then don't do that.
