+ Create private chains for virtual network firewall rules
+ </summary>
+ <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.

+ Detect CEPH and GPFS as shared FS
+ </summary>
+ <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
+ solution is to use different method to reboot or shutdown the

+ QEMU: Use 'raw' for 'volume' disks without format
+ </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.

+ 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.

+ QEMU: Fix block job progress reporting and advocate for READY event
+ </summary>
+ <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.

+ QEMU: Don't format image properties for empty drive
+ </summary>
+ <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.
