But we are talking about the Fedora 20 client atm, right? You just assume the bug would happen with Windows client too?

Interesting, what virtio and spice agent version have you installed in the Windows guest?

What is the host btw?

I am not aware of such bug. I guess you should open one.

Could you install debugging symbols and run remote-viewer under gdb, with SPICE_DEBUG=1 ? When it hangs, do "thread apply all bt" and copy paste the last logs and the fullbacktrace. That should help us.
