Upcoming patches will modify how we populate the capability cache in
tests to be more saner. This also means that the emulator binary and
architecture used in the test files using real capabilities must match
what the real capabilities have.

Currently the QEMU driver secretly sets the QEMU_AUDIO_DRV env variable
- VNC - set to "none", unless passthrough of host env variable is set
- SPICE - always set to "spice"
- SDL - always passthrough host env
- No graphics - set to "none", unless passthrough of host env variable is set
The setting of the QEMU_AUDIO_DRV env variable is done in the code which
configures graphics.
If no <audio> element is present, we now auto-populate <audio> elements
to reflect this historical default config. This avoids need to set audio
env when processing graphics.

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.
