Apparently, not all page faults on the guest result in a page fault in the host. I would like to intercept page faults on the guest that are not handled by the host.
I am not quite sure where (in the source code) can I monitor that?
Can any one give me code pointers to look at?
  		 	   		

You need to disable ept or not, and on Intel, load the kvm_intel module with bypass_guest_pf=0. With that, kvm will intercept all guest page faults.
