You've hit "illegal instruction". The program was compiled on a computer
that is probably newer than the current one and supports more
instructions. As far as I can tell, it is not related to VM, but just to
the fact that you can not hope to transport cado-nfs binaries from one
machine to another.

Regards,
Pierrick
