I would rephrase to:
-------------------------------
Under KVM recommendations
PCI passthrough recommendations
If you are running PCI passthrough with 16.04.x KVM and with the stock
QEMU package, update to the QEMU package that have DDW support. If you
do not update the package, you will hit data integrity issues as soon
as I/O is started on the adapter.
The package is available at:
