df769041c2 domain_capabilities: Don't report machine type for bhyve
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.

c51090fc99 qemu: Add support for generic PCIe Root Ports
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.

3c647ee4bb Switch to GSSAPI (kerberos) instead of the insecure DIGEST-MD5
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.

e433546bef qemu: Introduce label-size for NVDIMMs

80af11d3dd conf: Introduce @access to <memory/>
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.

b4e8a49f8d Introduce NVDIMM memory model
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.

1d9ab0f04a qemu: Allow empty script path to <interface/>
Before 9c17d665fd (v1.3.2 - I know, right?) it was possible to
have the following interface configuration:

  <interface type='ethernet'/>
    <script path=''/>
  </interface>

This resulted in -netdev tap,script=,.. Fortunately, qemu helped
us to get away with this as it just ignored the empty script
path. However, after the commit mentioned above it's libvirtd
who is executing the script. Unfortunately without special
case-ing empty script path.
