+        <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 does some sanity checks to
+          make sure domain will be able to run on destination. One of
+          requirements is that disk has to either be migrated too or
+          live on 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. Set process
+          affinity corretly from the start so that memory is allocated
+          on the configured nodes from the beginning.

+          Wireshark supports out of tree builds of dissectors since its
+          2.5.0 release. Adapt libvirt to that. This affects minimal
+          required version then too.

+        <description>
+          Usuaully, this would be viewed as an internal change that
+          should not concern users. However, since libvirt is written in
+          memory unsafe language some memory leaks might have been
+          actually fixed by using VIR_AUTOFREE(). It is definitely step
+          towards defensive programming.

+          block jobs anymore.

+        </summary>
+        <description>
+          Due to a bug libvirt was not allocating PCI address for
+          watchdog device nor it was telling it to qemu. This lead qemu
+          to chose one (the lowest one) which might not be hotpluggable.

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

+          virDomainShutdown would reboot or shutdown the host. The
+          solution is to use different method to reboot or shutdown the
+          container in that case (e.g. signal).

+        </summary>
+        <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.

+        <description>
+          Post parse callback adds the 'raw' type only for local files.
+          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 adviced to wait for
+          VIR_DOMAIN_BLOCK_JOB_READY event which does not suffer from
+          this problem.

+          If a -drive has no image, using image properties makes qemu

+          like cache/readonly/... in that case.
