173733b7a8 conf: Introduce virtio-pmem <memory/> model
The virtio-pmem is a virtio variant of NVDIMM and just like
NVDIMM virtio-pmem also allows accessing host pages bypassing
guest page cache. The difference is that if a regular file is
used to back guest's NVDIMM (model='nvdimm') the persistence of
guest writes might not be guaranteed while with virtio-pmem it
is.

To express this new model at domain XML level, I've chosen the
following:

  <memory model='virtio-pmem' access='shared'>
    <source>
      <path>/tmp/virtio_pmem</path>
    </source>
    <target>
      <size unit='KiB'>524288</size>
    </target>
    <address type='pci' domain='0x0000' bus='0x00' slot='0x05' function='0x0'/>
  </memory>

Another difference between NVDIMM and virtio-pmem is that while
the former supports NUMA node locality the latter doesn't. And
also, the latter goes onto PCI bus and not into a DIMM module.

08f8fd8413 conf: Add support for vDPA network devices
This patch adds new schema and adds support for parsing and formatting
domain configurations that include vdpa devices.

vDPA network devices allow high-performance networking in a virtual
machine by providing a wire-speed data path. These devices require a
vendor-specific host driver but the data path follows the virtio
specification.

When a device on the host is bound to an appropriate vendor-specific
driver, it will create a chardev on the host at e.g.  /dev/vhost-vdpa-0.
That chardev path can then be used to define a new interface with
type='vdpa'.

2508d10f67 conf: domain: sev: Make 'cbitpos' & 'reducedPhysBits' attrs optional
These XML attributes have been mandatory since the introduction of SEV
support to libvirt. This design decision was based on QEMU's
requirement for these to be mandatory for migration purposes, as
differences in these values across platforms must result in the
pre-migration checks failing (not that migration with SEV works at the
time of this patch).

Expecting the user to specify these is cumbersome and the same XML
cannot be re-used across different revisions of SEV. Since
we have SEV platform information saved in QEMU capabilities, we can
make the attributes optional and should fill them in automatically
in the QEMU driver right before starting it.

9d15647dcb Xen: Add writeFiltering option for PCI devices
By default Xen only allows guests to write "known safe" values into PCI
configuration space, yet many devices require writes to other areas of
the configuration space in order to operate properly. To allow writing
any values Xen supports the 'permissive' setting, see xl.cfg(5) man page.

This change models Xen's permissive setting by adding a writeFiltering
attribute on the <source> element of a PCI hostdev. When writeFiltering
is set to 'no', the Xen permissive setting will be enabled and guests
will be able to write any values into the device's configuration space.
The permissive setting remains disabled in the absense of the
writeFiltering attribute, of if it is explicitly set to 'yes'.

f1d7d6c2cf docs: documentation and schema for the new TPM Proxy model
QEMU 4.1.0 introduced a new device type called TPM Proxy, currently
implemented by PPC64 guests via a new virtual device called
'spapr-tpm-proxy' (see QEMU 0fb6bd073230 for more info).

The TPM Proxy device interacts with a TPM Resource Manager, a host
device capable of multiplexing the host TPM with multiple processes.
This allows multiple guests to access some TPM features at the
same time. Note that this mode of operation does not provide
full TPM features to be available for the guest - for that case
the guest still needs to assign a vTPM device (tpm-spapr for
PPC64 guests). Although redundant, there is currently no technical
limitation for a guest to assign both a vTPM and a TPM Proxy at the
same time.

This patch adds documentation and schema for a new TPM model
type called 'spapr-tpm-proxy' that creates this new TPM Proxy
device. This model is valid only for the 'passthrough' backend.
An example of a TPM Proxy device connected to a TPM Resource Manager
'/dev/tpmrm0' will look like this:

<tpm model='spapr-tpm-proxy'>
  <backend type='passthrough'>
    <device path='/dev/tpmrm0'/>
  </backend>
</tpm>

3dda889a44 conf: Add firmware blob configuration
QEMU has -fw_cfg which allows users to tweak how firmware
configures itself and/or provide new configuration blobs.
Introduce new <sysinfo/> type "fwcfg" that will hold these
new blobs.

It's possible to either specify new value as a string or
provide a filename which contents then serve as the value.

IBS can have the following values: "broken", "workaround",
"fixed-ibs", "fixed-ccd" and "fixed-na".

104dadcff6 qemu: Implement the SBBC pSeries feature
This patch adds the implementation of the SBBC pSeries feature,
using the QEMU_CAPS_MACHINE_PSERIES_CAP_SBBC capability added
in the previous patch.

Like the previously added CFPC feature, SBBC can have the values
"broken", "workaround" or "fixed". Extra code is required to handle
it since it's not a regular tristate capability.

This is the XML format for the cap:

<features>
  <sbbc value='workaround'/>
</features>
