The failure is here:

  https://github.com/libguestfs/libguestfs/blob/master/appliance/init#L110-L117

But actually it's a failure in whatever provides the dhclient /
dhclient-script in your host.  What is the host system?

This was reported before, but not resolved:

  https://www.redhat.com/archives/libguestfs/2015-June/msg00361.html

It can be worked around by changing the code (see above) to use dhcpcd
or another dhcp server.  But basically it's a bug in your host distro
that they are supplying a dhclient-script that doesn't work when
/etc/fstab is missing, so you need to report it there.
