See my comment below. + This definition should be renamed VM_EVENT_FLAG_ALTERNATE_P2M and moved to the appropriate location. It should also be checked for all events, not just for mem_access, similar to how VM_EVENT_FLAG_VCPU_PAUSED is checked for, as we might want to switch views in response to a variety of events. Right now I worked around this be specifying the response to a singlestep event as if it was a response to a mem_access one, but that's very hackish.
