fails with `unknown option'

[sevenEng]

while trying out the unikernel under the directory example/, it crashes with the following output:

Parsing config from unikernel.xl
MirageOS booting...
Initialising timer interface
Initialising console ... done.
unikernel: unknown option `--hello', did you mean `--help' ?
Usage: unikernel [OPTION]...
Try `unikernel --help' for more information.
Mirage exiting with status 1
Do_exit called!

and i'm on ubuntu 14.04, with ocaml 4.02.3, mirage-xen 2.6.0, the lib version is 0.3.2

I'm confronted with similar situation on EC2:

============= Init TPM Front ================

The unikernel image was built on Ubuntu 14.04 with OCaml 4.03.0 and the library versions being same.

The above error (mine) was resolved by using register ~argv:Mirage.no_argv ... in config.ml.
