+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
+package.

+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.
