It is in qemu-kvm-1.0 as well. But like you said fedora carries 0.15.1
that doesn't have it.

which doesn't have the spice side fix. but 0.10.0 has it, and it is
closest to 0.9.1. I assume this is from the fedora package as well since
you mentioned qemu-kvm is from a fedora package? seems the latest is
indeed 0.9.1-1, can you test
http://koji.fedoraproject.org/koji/buildinfo?buildID=273917
(spice-server-0.10.0-1)?
