From 84757f7e67cda3df8b04e06fbdeecc266415d2f3 Mon Sep 17 00:00:00 2001 From: Max Reitz Date: Wed, 9 Oct 2013 14:42:00 +0200 Subject: qcow2: Fix snapshot restoration in snapshot_create If the new snapshot table could not be written in qcow2_snapshot_create, the old snapshot table has to be restored in memory and the new one released. This should include restoration of the old snapshot count as well, which is added by this patch.
