There's something really weird going on here with your system. Could it be that /var/tmp is not readable? Tomas already suggested doing this: &nbsp; rm -rf /var/tmp/.guestfs-* then try to run libguestfs-test-tool again.&nbsp; If it still doesn't work, have a look at the permissions of files in /var/tmp/.guestfs-0 or if you see any SELinux audit messages.
