Xiao Guangrong 34ab9e9743 migration: detect compression and decompression errors ... Currently the page being compressed is allowed to be updated by the VM on the source QEMU, correspondingly the destination QEMU just ignores the decompression error. However, we completely miss the chance to catch real errors, then the VM is corrupted silently To make the migration more robuster, we copy the page to a buffer first to avoid it being written by VM, then detect and handle the errors of both compression and decompression errors properly Reviewed-by: Peter Xu <peterx@redhat.com> Signed-off-by: Xiao Guangrong <xiaoguangrong@tencent.com> Message-Id: <20180330075128.26919-5-xiaoguangrong@tencent.com> Signed-off-by: Dr. David Alan Gilbert <dgilbert@redhat.com>		2018-04-25 18:04:08 +01:00
