Ugh. This is really really bad news. We've set the freeze date at july
19th so that we had a chance to finish things for the Fedora 14 feature
freeze a week later (July 27th). But unless we can get spice support
into the qemu in fedora we will have a hard time getting spice into
fedora (no users of the library), and if spice support is not in
upstream qemu its very unlikely that we'll get spice support in the F14
qemu (standard "focus on upstream" fedora prio).

So, this basically means that we're likely to miss spice in F14, having
to wait for F15, thus missing half a year of testing and use. That sucks
big-time...

Yes, this was in our plan. 0.13 was supposed to go out in june:ish, and
then we'd be able to land right after that. Its probably ok for fedora
to backport a feature like that, while it not being acceptable to add a
such a patch that is not upstream.

Sucks...

Do you have any ideas how to get "live" migration (spice 0.4-style) into
the new spice?
