+    CVE-2014-3633: qemu: blkiotune: Use correct definition when looking up disk
+    
+    Live definition was used to look up the disk index while persistent one
+    was indexed leading to a crash in qemuDomainGetBlockIoTune. Use the
+    correct def and report a nice error.
+    
+    Unfortunately it's accessible via read-only connection, though it can
+    only crash libvirtd in the cases where the guest is hot-plugging disks
+    without reflecting those changes to the persistent definition.  So
+    avoiding hotplug, or doing hotplug where persistent is always modified
+    alongside live definition, will avoid the out-of-bounds access.
+    
+    Introduced in: eca96694a7f992be633d48d5ca03cedc9bbc3c9aa (v0.9.8)
+    Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1140724
+    Reported-by: Luyao Huang <lhuang@redhat.com>
