Description of problem:

When I close the lid of laptop, guest only come back some of the times.




Version-Release number of selected component (if applicable):

guest: kernel-3.15.10-201.fc20.x86_64
host: kernel-core-3.17.0-300.fc21.x86_64
      qemu-system-x86-2.1.2-4.fc21.x86_64

It also happened when the host was on F20.


How reproducible:

Around 20% of the time the guest hangs.  Sometimes it is only the spice client what is broken.  But that 20% of the time, even ping to the guest don't work.

Steps to Reproduce:
1.  close the lid of laptop (suspend)
2.  wait 1h or more
3.  open lid (wakeup)

Actual results:

Guest is hanged

Expected results:

Guest answer correctly.
