In part thats a legal question so only a lawyer can really tell you what
is and isn't the line for derivative works. 

Philosophically I can see the argument that the moment you hit a
hypervisor trap its akin to running another app (and an app which
communicates via that interface with many othr apps) so your Linux
kernel side code would be GPL and whatever it fires up which handles the
trap come syscall probably isn't. But I'm not a lawyer and neither you
nor anyone else, nor a court reviewing a case should consider the
statement above a guideline of intent.
