Subject: [Qemu-devel] [PATCH 0/2] fix migration of zero pages
Date: Thu, 6 Jun 2013 10:36:03 +0200 [thread overview]
Message-ID: <1370507765-2806-1-git-send-email-pl@kamp.de> (raw)
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.
Peter Lieven (2):
Revert "migration: do not sent zero pages in bulk stage"
migration: do not overwrite zero pages
