Ok, first of all, thanks for doing it and sharing the draft.

It is indeed a bit short, but that is not necessarily an issue. However,
I'd try to think whether there isn't some more interesting and useful to
know (for our users) content that we/you could not add...

For instance, in the very first sentence you mention both "QEMU" and the
"old qemu-traditional". Apart from adding the proper hyperlinking, what
about stating once more, as clearly as possible, what the differences
are, i.e., which one is what, which one is the default, etc.?

I know that piece of info is out there already, but, to me, this really
looks like something really easy to get confused about, even for
experienced users.

"A thing called dirty tracking of physical memory", worth expanding a
little bit to tell people what it is and why it is important? Still in
that sentence, I'm not sure I understand what the following means: "but
it has also been backported to 4.2, so itâs not that new".

"Missing feature_s_?" ?

What about some of the development that is happening right now, whether
or not it is targeting 4.4? You've got QEMU stubdom there already, I
know, but is that the only thing happening on the qemu side? Perhaps we
can quickly list what we've got in George's development update that is
qemu related with a few words of context? I'm sure there's someone
(Fabio Fantoni?) working on improved USB controller, spice and qxl
support... No need to have a detailed tech report, but it perhaps is
worth at least mentioning?

Another thing that I think could be interesting to (re)state is what
does it mean to achieve the goal of getting rid of qemu-traditional? Why
is it a good thing? For instance, in 4.4 there will be config options
for using the distro provided QEMU, instead of cloning and building our
own (whether it is upstream or traditional), wont it? If yes, that I
think is quite a _big_deal_ (or so I always hear from distro people!).

So... Am I talking nonsense? Do you think it's worth trying to add at
least some of the things I mentioned?

Thanks and Regards,
Dario
