Move it to the place where actually interleaving elements can be placed.

'diskSourceNetwork' schema define was rather big and it would be hard to
simplify it. Split out the host portion subelement into a separate
define.

They don't contain any elements to interleave.

This patch introduces

    <cache level='N' mode='emulate'/>
    <cache mode='passthrough'/>
    <cache mode='disable'/>

sub element of /domain/cpu. Currently only a single <cache> element is
allowed.

We are currently parsing only rx/frames/max because that's the only
value that makes sense for us.  The tun device just added support for
this one and the others are only supported by hardware devices which
we don't need to worry about as the only way we'd pass those to the
domain is using <hostdev/> or <interface type='hostdev'/>.  And in
those cases the guest can modify the settings itself.

docs/schemas directory is meant for schemas which are installed on the
system. The schema for the news file does not need to be installed.
Store it along with the file it describes for simplicity.

Similar to commit c3c2cc65, use a literal newsline instead of \n
inside the brackets.

Creating dummy <change> elements was a workaround for the
HTML DTD not allowing empty <ul> elements, but we can do
better by tweaking the the XSLT stylesheet.

Since this file gets changed (and broken) rather often, introduce a
schema file so that the test suite can validate it.

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.

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>

QEMU 2.9 introduces the pcie-root-port device, which is

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.

With that users could access files outside /dev/shm.  That itself
isn't a security problem, but might cause some errors we want to
avoid.  So let's forbid slashes as we do with domain and volume names
and also mention that in the schema.

This part introduces new xml elements for file based
memorybacking support and their parsing.
(It allows vhost-user to be used without hugepages.)

New xml elements:
<memoryBacking>
  <source type="file|anonymous"/>
  <access mode="shared|private"/>
  <allocation mode="immediate|ondemand"/>
</memoryBacking>

Example:

  <network>
     ...
     <mtu size='9000'/>
     ...

If mtu is unset, it's assumed that we want the default for whatever is
the underlying transport (usually this is 1500).

This setting isn't yet wired in, so it will have no effect.
