+        <description>
+          Historically firewall rules for virtual networks were added
+          straight into the base chains. This works but has a number of
+          bugs and design limitations. To address them, libvirt now puts
+          firewall rules into its own chains.

+        <description>
+          When starting a migration libvirt performs some sanity checks
+          to make sure domain will be able to run on the destination.
+          One of the requirements is that the disk has to either be
+          migrated too or be accessible from a network filesystem. CEPH
+          and GPFS weren't detected as a network filesystem.

+          Allocate QEMU memory at the configured NUMA nodes from start
+        </summary>
+        <description>
+          Libvirt used to just start QEMU, let it allocate memory for
+          the guest, and then use CGroups to move the memory to
+          configured NUMA nodes. This is suboptimal as huge chunks of
+          memory have to be moved. Moreover, this relies on ability to
+          move memory later which is not always true. A change was made
+          to set process affinity correctly from the start so that memory
+          is allocated on the configured nodes from the beginning.

+          If the container is really a simple one (init is just bash and

+          virDomainShutdown would reboot or shutdown the host. The

+        <description>
+          Storage pools might want to specify format of the image when
+          translating the volume thus libvirt can't add any default
+          format when parsing the XML. Add an explicit format when
+          starting the VM and format is not present neither by user
+          specifying it nor by the storage pool translation function.

+          Remote files can also have backing store (even local) so we
+          should do this also for network backed storage.

+        <description>
+          In some cases QEMU can get to 100% and still not reach the
+          synchronised phase. Initiating a pivot in that case will fail.
+          Therefore it is strongly advised to wait for
+          <code>VIR_DOMAIN_BLOCK_JOB_READY</code> event which does not
+          suffer from this problem.

+        <description>
+          If a <code>-drive</code> has no image, then formatting
+          attributes such as cache, readonly, etc. would cause errors to
+          be reported from QEMU. This was fixed by not supplying the
+          attributes for devices without an image.
