+Subject: [PATCH] lib: libvirt: stop using <shareable/> for appliance disk
+ (RHBZ#1518517)
+
+Commit aa9e0057b19e29f76c9a81f9aebeeb1cb5bf1fdb made the libvirt backend
+use <shareable/> for the disk of the appliance, since at that time all
+the instances were using the disk directly.
+OTOH, commit 3ad44c866042919374e2d840502e53da2ed8aef0 switched to
+overlays for read-only disks, including the appliance, so effectively
+protecting the appliance.
+
+Because of this, the libvirt backend does not need <shareable/> anymore.
+
+Thanks to: Daniel Berrange, Richard W.M. Jones,  Peter Krempa.
