Hi all, after several tests it seems that the interrupt assignment on the host systems influences the kvm performance drastically. If eth0, video and usb are on seperate interrupts the perfomance is way better than if they are shared (that means on the same one). Normally this should not matter. But why is it within kvm? Does kvm somehow hook up into the interrupt service routines? My guest is Windows XP SP3.
