Yes. It's a ring buffer, with rptr pointing to the first used element and wptr pointing to the first free element. So, what we need is a function to move the content we are interested (between rptr and wptr) in to the head of the ring buffer, set rptr to 0, set wptr to count. We obviously need to do that in post_load(), but as I've noticed meanwhile also in pre_save, otherwise old qemu will get things wrong in case the buffer is wrapped (rptr > wptr). cheers, Gerd
