This is a case where xen virtualizaion is used and Suricata can not start unless compiled in with "--disable-gccmarch-native" on the particular virtual guest.

There is no other err msg(and/or core file even when compiled with debugging) besides the

Illegal instruction (core dumped)

while a more descriptive err message or a check could point to the right direction.

No other checks could "confirm" that this is a virtual machine besides(at least in this particular case):
