We are enforcing #!/bin/bash at the beginning of the scripts and bash is
installed in every guest.

No idea in that case.  Suggest using guestfish on the guest
after virt-customize has run to check that the files are
really being installed in the right places and have the
right permissions etc.

Read my programming and virtualization blog: http://rwmj.wordpress.com
virt-top is 'top' for virtual machines.  Tiny program with many
powerful monitoring features, net stats, disk stats, logging, etc.
http://people.redhat.com/~rjones/virt-top

Figured it out.

The generated script had CRLF line termination. When we have removed the \r from
the end if line everything started to work.

Thanks for the help.

Peter
