You should use rpm -U (upgrade), not -i (install). Or better
yet, yum install <file>

That's because you now have the two versions installed. Remove
them using rpm -e spice-server-0.10.0-1 spice-server-0.9.1-1 and
then reinstall the version you want.

As a general rule, never use --force unless you're absolutely
sure of what you're doing, and prefer to use yum as much as
possible.
