If we can poison a page in the backing file, how do we know the
corresponding gpa and hpa?
I think you currently can't know it's gpa (why do you want to?); the
upcoming NUMA enhancements should allow this (the plan is to have a
file per guest NUMA node, so we can tell the host what policy to apply
for that node).
gpa->hpa translation can be derived from /proc/pid/maps.
That would be gpa->hva.
