[Qemu-devel] [PATCHv2 0/2] fix migration of zero pages

[Peter Lieven]

There have been reports that migration is broken on pseries by Alexey 
Kardashevskiy.
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.

Peter Lieven (2):
  Revert "migration: do not sent zero pages in bulk stage"
  migration: do not overwrite zero pages
