-Subject: [PATCH] launch: direct: Omit locking option for non-file disks
- (RHBZ#1516094)
-
-QEMU does not accept options unrecognized by the block driver
-in use. Disable locking only for read-only disks that are
-file-backed, as that's the only block driver it is supported
-with.

-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.
