Eh? I don't follow you here.
guest writes in qemu set the qemu dirty bitmap (for
cpu_physical_memory_get_dirty()), but guest accesses in kvm won't,
unless you enable dirty tracking and synchronize kvm's bitmap to
qemu's. See the changes to migration.c in kvm's qemu.
Oh yes, that falls under the save/restore TODO item.
