Personally I would just send one here. > - is ok if KVM is disabled? more testing required If I understand correctly it used to interrupt guest code execution whereas now it simply invoked a callback in the I/O thread. Normally this callback will raise a guest interrupt and get the vCPU to notice that I/O has completed. So I think this should work. Stefan
