It turned out that migration will fail in general as soon as a page is zero on the source, but not on the destination. I thus reverted the skipping of zero pages in bulk transfer phase and added a patch that does not (over)write zero pages at the destination. v2: - keep skipped pages fields in monitoring and qmp intact to avoid compatiblity issues.
