With QEMU, they have the "kvm=off" option which hides hypervisor info 
from the guest.
See: https://www.redhat.com/archives/libvir-list/2014-August/msg00512.html

I did try to replicate this a while back but didn't have much success - 
maybe I missed a flag?
The QEMU diff seems relatively small, see: 
http://lists.gnu.org/archive/html/qemu-devel/2014-06/msg00302.html

Having another go at doing this is on my to-do list, but not very near 
the top!
