It seems to stop working if i supply -no-kvm-irqchip. Can you try to 
reproduce this?

We introduced that parameter because we encountered some problems with 
the e1000 kernel driver stopped to work in some
guests after live migration with a "nobody cared about interupt" (i 
don't know the exact error anymore). supplying
-no-kvm-irqchip made live migration of these guests possible...
Sounds that familiar to someone?
