This should enable faster migration of memory pages that the destination
tries to read before they are migrated from the source.
+ * qemu: Add support for mapping iothreads to virtqueues of ``virtio-blk`` devices
+
+ QEMU added the possibility to map multiple ``iothreads`` to a single
+ ``virtio-blk`` device and map them even to specific virtqueues. Libvirt
+ adds a ``<iothreads>`` subelement of the ``<disk> <driver>``
element that
+ users can use to configure the mapping.
+
+ * qemu: Allow automatic resize of block-device-backed disk to full size of the device
+
+ The new flag ``VIR_DOMAIN_BLOCK_RESIZE_CAPACITY`` for
+ ``virDomainBlockResize`` allows resizing a block-device backed ``raw`` disk
+ of a VM without the need to specify the full size of the block device.
+
* **Improvements**
+ * qemu: Improve migration XML use when persisting VM on destination
+
+ When migrating a VM with a custom migration XML, use it as a base for
+ persisting it on the destination as users could have changed non-ABI
+ breaking facts which would prevent subsequent start if the old XML were used.
+
+ * qemu: Simplify non-shared storage migration to ``raw`` block devices
+
+ The phase of copying storage during migration without shared storage
+ requires that both the source and destination image are identical in size.
+ This may not be possible if the destination is backed by a block device
+ and the source image size is not a multiple of the block device block size.
+
+ Libvirt aleviates this by automatically adding a ``<slice>`` to match the
+ size of the source image rather than failing the migration.
+
* **Bug fixes**
+ * qemu: Various migration bug fixes and debuggability improvement
+
+ This release fixes multiple bugs in virsh and libvirt in handling of
+ migration arguments and XMLs and modifies error reporting for better
+ debugging.
