installed spice debuginfo and got more details. Reason seems to be
this bug: http://cgit.freedesktop.org/spice/spice/commit/?id=4019a8801d7a67035749562c0c1f403c24f36b0b
As the CPU consumption is quite nasty I advise anyone who gets similar issues
on FC19 nodes to jump onto FC20. spice-server 0.12.5 including the bugfix has
been pushed to the testing repos and should be available the next weeks.
