[root@localhost ~]# rpm -i spice-server-0.10.0-1.fc16.x86_64.rpm
        file /usr/lib64/libspice-server.so.1.0.2 from install of
spice-server-0.10.0-1.fc16.x86_64 conflicts with file from package
spice-server-0.9.1-1.fc16.x86_64

So I force install
rpm -i --force spice-server-0.10.0-1.fc16.x86_64.rpm

yum list installed:
spice-server.x86_64                     0.9.1-1.fc16                 @anaconda-0
spice-server.x86_64                     0.10.0-1.fc16                installed

0.9.1-1.fc16 seems not be overrided.

So  first, I am not sure qemu-kvm will use 0.10.0-1.fc16  or 0.9.1-1.fc16

Second, this is a random bug, I am not sure when it will  appear again.
