You pretty much need this library and qemu linked against it.

I'd probably say status of project is, initial implementation in
process of upstreaming.

Not really, I'm not a drawer but I could probably try and draw something.

Nope. the idea is to get the pieces upstream first and then have it just work.

Again project is currently on its way upstream, making definitive comments is
hard as they go out of date too quick. So the answer to this question is it
dependson what version of what stuff you have. qemu 2.5 only works with local
VMs using GTK+. qemu 2.6 is hoped with the correct spice pieces in place to work
wih spice. There are of course libvirt pices to put in the place as
well and then
boxes for GNOME will need work. This stuff is all mostly in progress
upstreaming,
and awaiting releases of various components in the virt stack, like spice*.

The guest OS requires 4.4, the host OS really needs dma-buf but otherwise
should work with modern mesa based GL drivers.

Nothing is known on this. No other driver can be used. Red Hat has an
interest in doing that work at some point but there is no timeline, and no
real work been done, so if anyone wanted to learn about writing WDDM
drivers here's a good time to learn!.

gnome-shell is the only thing I have to care about from a Red Hat perspective,
we've been testing various games and using piglit on it. Most things
run, but it's
exactly blisteringly fast yet, we've left a fair bit of performance
work for after the
initial implementation is upstream.

I think once we have some initial releases upstream of the various pieces I'l
try and update the website again, at the moment things are too in flux for me
to stay on top off.
