After the steps below, I am sure it is spice-server-0.10.0-1.fc16.x86_64 works.
[root at localhost pkgconfig]# ldd /usr/bin/qemu-kvm
      libspice-server.so.1 => /usr/lib64/libspice-server.so.1

The software suits related:

This random bug appears at least 2 time one day before fixing.
So in the coming 2 days, if this bug does't appear again, I will
assume spice-server-0.10.0-1.fc16.x86_64.rpm fix it :)
