d5283b7be2 Fix format network dns doc
The code block on the srv name in the formatnetwork page is confusing
since the actual parameter is service. Moving the code block to the
service work makes it better.

85523cfae0 docs: Clarify use of virtio-scsi model for SCSI controllers
The current formulation can lead people to believe SCSI
controllers only allow the virtio-scsi model, but really the
only difference is that you have to use model='virtio-scsi'
where you would use model='virtio' for another device.

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.

b44f35e2cf docs: kbase: sev: Adjust the claims that virtio-blk doesn't work
Using virtio-blk with SEV on host kernels prior to 5.1 didn't work
because of SWIOTLB limitations and the way virtio has to use it over
DMA-API for SEV (see [1] for detailed info). That is no longer true, so
reword the kbase article accordingly.

For reference, these are the upstream kernel commits lifting the
virtio-blk limitation:
