The bitmaps are transmitted many times in their entirety, but only the last copy actually means something. The others are lost. This means you should use the non-live interface (register_savevm). This will simplify the code a lot.

But what if the dirty bitmap is really big?

For example, for 5 Pb drive the bitmap with granularity 65536 will be of 2 Gb size. So, shouldn't it be migrated iteratively for live migration?
