qemu-2.3.1-7.fc22 seems to break interaction with the guest spice-vdagent. There's even reports of this hanging windows VMs The issue is that the package was built against spice-server 0.12.6, but if it runs against an older spice-server, everything misbehaves.

Pushing spice 0.12.6 to stable will more or less fix this, but anyone hitting issues in the interim can do: sudo yum --enablerepo=updates-testing update spice\*

Thank you very much for the solution. I installed spice 0.12.6 packages and this solved my problem.
spice-server-0.12.5-6.fc22.x86_64 → b0rken spice-server-0.12.6-1.fc22.x86_64 → works
