I connected using the spice gtk client. Same black screen. So I guess it
has to do with the server (qemu spice support). Fedora qemu package had
a lot of spice patches, all merged in qemu 1.0. Upstream said it
shouldn't be needed to apply the patches though (and I didn't).

There was also some other spice client, maybe spicec, but that depended
on yet another package (cegui or something), but an older version than
what Cauldron had. Upstream said they'd replace it with a gtk version
(which I already packaged), so I excluded the old client from the spice

Indeed :)

I think I changed libvirt to support spice, but not sure. I'm focussing
on gnome-boxes and I had to package a lot of things to get it to
actually run a VM. Virt-manager does work though (started Mageia 1 dvd
in a VM).

Any pointers on how to add support in the distribution? I guess maybe I
should try to make a VM in gnome-boxes and start a Fedora iso.
