Why impossible? The existing watchpoints replace original physical
memory with io_mem_watch MMIO, virtual addresses are translated to
physical in exec.c:tlb_set_page(). The only missing piece is to allow
setting watchpoints with physical addresses directly.
Since KVM can handle MMIO, I think it should also be able to handle
watchpoints.
Not on RAM areas.
