Well, I already treat kernel mappings specially (effectively I know the guest's PAGE_OFFSET): they're kept identical in all the 4 shadows, and need explicit guest flushing. Whether the guest shares (non-kernel) page tables or not, I will shadow them dumb as separate page table pages the way things stand. So, yes, shared libs will be my main issue. Address space randomization means I can't even use a heuristic such as looking for the page at the same address in other shadows. I'll come up with something. Anyway, virtio what I'm *supposed* to be doing today...
