From 95d6aff7878309037f82acaae756108f29e42309 Mon Sep 17 00:00:00 2001 From: Peter Krempa Date: Tue, 15 Jul 2014 10:31:36 +0200 Subject: [PATCH] qemu: blockcopy: Initialize correct source structure 4cc1f1a01fb338de939ba88eb933931687b22336 introduced a crash when doing a block copy as virStorageSourceInitChainElement was called on "disk->mirror" that is still NULL at that point instead of "mirror" which temporarily holds the mirror source struct until it's fully initialized. This resulted into a crash as a NULL was dereferenced.
