/domain/devices/disk/driver/@name is not a required or mandatory
attribute according to formatdomain, and indeed it was agreed on
IRC that the attribute is "optional for input, recommended (but
not required) for output". Currently the schema requires the
attribute, causing virt-xml-validate to fail on disk config where
the driver name is not explicitly specified. E.g.
# cat test.xml | grep -A 5 cdrom
<disk type='file' device='cdrom'>
<driver type='raw'/>
<target dev='hdb' bus='ide'/>
<readonly/>
<address type='drive' controller='0' bus='0' target='0' unit='1'/>
</disk>
# virt-xml-validate test.xml
Relax-NG validity error : Extra element devices in interleave
test.xml:21: element devices: Relax-NG validity error : Element domain failed to validate content
test.xml fails to validate
Relaxing the name attribute to be optional fixes the validation
# virt-xml-validate test.xml
test.xml validates

qemu requires that the topology equals to the maximum vcpu count.
Document this along with the API to set maximum vcpu count and the XML
element.

After the release it's necessary to add a new <release> section for the
upcoming release. Add a template so that it does not have to be
compiled over and over again.
Pool types that have the VIR_STORAGE_POOL_SOURCE_NAME flag set
allow omitting the <name> element and instead fill out the pool name
from the <source><name> element.
Relax the schema to make <name> optional for these pools.
Expressing that at least one of these is required is out of scope
of the schema.

When reading release notes, patch summary is not always the best
description of what users can expect in new version. I propose
changing it slightly so that it describes what exactly happens and
when.
However, we do not have to add every single code change to the news
file, that would be ridiculous and unreadable for users. If the patch
subject needs changes like this one, I'm rather tempted to say that
such changes should not be in the news file at all. So that would be
the other way how to fix this.

This brings the libvirt version of this RNG file in line with the same
file in netcf (as soon as the corresponding patch there is ACKed and
pushed).
There's no reason to require it when defining an interface (the config
option it corresponds to is optional), and it isn't even output in the
status of an interface.

A mediated device will be identified by a UUID (with 'model' now being
a mandatory <hostdev> attribute to represent the mediated device API) of
the user pre-created mediated device. We also need to make sure that if
user explicitly provides a guest address for a mdev device, the address
type will be matching the device API supported on that specific mediated
device and error out with an incorrect XML message.
The resulting device XML:
<devices>
<hostdev mode='subsystem' type='mdev' model='vfio-pci'>
<source>
<address uuid='c2177883-f1bb-47f0-914d-32a22e3a8804'>
</source>
</hostdev>
</devices>

For some drivers the domain's machine type makes no sense. They
just don't use it. A great example is bhyve driver. Therefore it
makes very less sense to report machine in domain capabilities
XML.

The attribute can be used to request a specific way of checking whether
the virtual CPU matches created by the hypervisor matches the
specification in domain XML.

QEMU 2.9 introduces the pcie-root-port device, which is
a generic version of the existing ioh3420 device.
Make the new device available to libvirt users.
RFC 6331 documents a number of serious security weaknesses in
the SASL DIGEST-MD5 mechanism. As such, libvirtd should not
by using it as a default mechanism. GSSAPI is the only other
viable SASL mechanism that can provide secure session encryption
so enable that by defalt as the replacement.

For NVDIMM devices it is optionally possible to specify the size
of internal storage for namespaces. Namespaces are a feature that
allows users to partition the NVDIMM for different uses.

Now that NVDIMM has found its way into libvirt, users might want
to fine tune some settings for each module separately. One such
setting is 'share=on|off' for the memory-backend-file object.
This setting - just like its name suggest already - enables
sharing the nvdimm module with other applications. Under the hood
it controls whether qemu mmaps() the file as MAP_PRIVATE or
MAP_SHARED.
Yet again, we have such config knob in domain XML, but it's just
an attribute to numa <cell/>. This does not give fine enough
tuning on per-memdevice basis so we need to have the attribute
for each device too.

NVDIMM is new type of memory introduced into QEMU 2.6. The idea
is that we have a Non-Volatile memory module that keeps the data
persistent across domain reboots.
At the domain XML level, we already have some representation of
'dimm' modules. Long story short, NVDIMM will utilize the
existing <memory/> element that lives under <devices/> by adding
a new attribute 'nvdimm' to the existing @model and introduce a
new <path/> element for <source/> while reusing other fields. The
resulting XML would appear as:
<memory model='nvdimm'>
<source>
<path>/tmp/nvdimm</path>
</source>
<target>
<size unit='KiB'>523264</size>
<node>0</node>
</target>
<address type='dimm' slot='0'/>
</memory>
So far, this is just a XML parser/formatter extension. QEMU
driver implementation is in the next commit.

bhyve supports 'gop' video device that allows clients to connect
to VMs using VNC clients. This commit adds support for that to
the bhyve driver:
- Introducr 'gop' video device type
- Add capabilities probing for the 'fbuf' device that's
responsible for graphics
- Update command builder routines to let users configure
domain's VNC via gop graphics.
